Do-it-yourself lovato gas reducer repair 4 generations In detail: do-it-yourself 4-generation do-it-yourself lovato gas reducer repair from a real master for the site my.housecope.com. Like I do not like endrio jan 26, 2009 Hello, help with advice if anyone has encountered such a breakdown. I had a 4-generation LPG Lovato, it was the turn to change the filter on the gearbox (unscrewed on the gearbox with a hexagon) made two turns as the bolt jammed neither there nor back, only a little free play. At the station they only say to change the gearbox (3500r + 500r setting + 600r setting). So I would like to ask if it is possible to unscrew the filter without resorting to buying a new gearbox? Unscrew it only on the "cold" one as you unscrew it, spray WD 40, you can tap the meme from the end on the screw (carefully), I did that, but in general, if there is a pre-filter, then it makes no sense to change (divorce for money 400 rubles + replacement) Like I do not like alex150 26 Jan 2009 Hello, help with advice if anyone has encountered such a breakdown.

The filter in the gearbox does not need to be changed, but you can rinse it without removing it. You disconnect the hose from the ramp and lengthen it, direct the end of the hose to a light surface and forcibly turn on the reducer valve (remove the standard wires from the coil of the electric valve, in their place are 2 wires, one for the ground, the second to the “+” battery). First, the black gas will FLY from the hose, then it will brighten. You will observe the filter cleaning process on a light surface. When the gas from the hose does not leave black traces on the surface, this means that the filter has been flushed. I always do this procedure before changing the fine filter. Video (click to play).

In a previous article, I talked about how to disassemble a Tomasetto AT-07 gas reducer at home.This time it will be about the gas reducer again, and today you will learn how to disassemble the Lovato gas reducer and install the repair kit. The need to disassemble and clean the gearbox arises when certain symptoms indicate malfunctions. How to understand that it is time to clean the gearbox is written in this article. A set of hexagons and screwdrivers; Gearbox repair kit Lovato; White Spirit, detergent; Rags. Safety comes first! Before how to disassemble the reducer: find a well-ventilated area, turn off the gas supply, remove the negative terminal from the battery. And most importantly, remove any sources of fire! 1. So, the gas supply is shut off, all safety measures are observed, you can proceed. The first step is to remove the gas supply hoses and dismantle the reducer. 2. Then we take the hexagon “H4” and unscrew the 6 bolts securing the upper gearbox cover. 3. They removed the cover, under which the first membrane is located. We pry on the membrane and remove it in the direction indicated in the photo. 4. You will then have access to the rocker arm. Remove the two rocker arm mounting bolts. 5. Unscrew the sensitivity adjustment screw. 6. Hook the rocker arm with a screwdriver and remove it. 7. Unscrew 4 bolts with a hexagon, then remove the diaphragm and the spring located under the diaphragm. 8. Turn the gearbox over and unscrew the 8 fixing screws, remove the cover together with the spring located under it. 9. Further, according to the same principle, we remove the membrane. 10. After you dismantled the gearbox, clean it, wash it, and also replace all necessary rubber bands and oil seals. Allow all parts to dry before assembly. Assembly is carried out in reverse order. That's all for me, thank you for your attention and see you again at the GBOshnik. In gas equipment, the reducer is given the greatest importance among all units. Its task: to provide the driver with an opportunity to lower the pressure that comes from the cylinder. Repair, namely adjustment, on a car's gearbox provides for working with one or two regulators: this is the main difference. In principle, a gas pressure regulator is a primitive pressure regulator designed to maintain a standard pressure value from the fuel consumption independently. As practice shows, the device supports it with insignificant fluctuations. The pressure decreases slightly with increasing gas flow. This is not a very significant point, but it requires attention. The Lovato gearbox design is characterized by versatility, simplicity and reliability. For Turkish semi-handicraft manufacturers, the manufacturer is a role model. Almost all generations of Turkish gearboxes have adopted the design of a flattened "drum", on the ends of which there are two stamped covers. Company "OFFICINE Lovato S.p.A." belongs to a family-type enterprise which was founded in the post-war period under conditions of an acute shortage of fuel. In modern conditions, Lovato is one of the leaders in the world market for gas cylinder systems. Repair, namely adjustment, of Lovato analogues depends on the following factors: generations of the mechanism; the number of regulators; fuel system. Manufacturer's product range: Reducer propane Lovato vacuum 90 and 140 kW. The device is intended for systems of the 1st generation of LPG on a carburetor type car with a capacity of up to 123 horsepower. The gearbox is intended exclusively for conversion to propane. Propane Lovato reducer electronic 90, 140, 170 kW. The device is designed for HBO systems of the 1st, 2nd and 3rd generations on auto injection, mono-injector and carburetor types with engine power up to 123 horsepower. The reducer is designed for propane-butane. Lovato methane reducer. The 2nd generation device is used for converting cars and buses to methane fuel. Repair, namely adjustment, of the gearbox provides for orientation in its settings. Propane counterparts mainly have two regulators, but they also meet with one. Methane type reducers are almost always characterized by one regulator. In their management, these settings are the most problematic. Repair for the gas generation of reducers with one unique setting involves manipulating exclusively the pressure of the transmitted gas. Vehicle owners with particular enthusiasm prefer to "turn up" the pressure on their own. Having set the only correct and, which is very important, the true value of the pressure, the fuel reducer alone will make it possible to limit the consumption of gas at operating capacities due to an element called the screw of greed. The repair has some difficulties in the case when the screw is in the "closed" position. To maintain idle speed, in this case, it is required to build up pressure, the process of which includes: Checking the gearbox before adjusting, namely, whether the "greed screw" is open. After the implementation of the previous stage, you can start adjusting work. Gearbox device Lovato Directly the gas regulator lovato is presented in the form of a screw compressing the spring. In order to install it, you should consider: when twisting, the gas supply will be reduced by the reducer; when twisting - build up. Sometimes screws are found with a left-hand thread, most often it is a right-hand thread. This moment depends on the manufacturer's design imagination. To slightly simplify this task, it is necessary to take into account: for any rotation, the above characteristics of the change in gas pressure are characteristic of it. Idling adjustment in vehicles is explained by the degree of shaking of the engine. Its quiet work indicates that the gearbox repair was done competently and efficiently. So, we start the engine and hold the throttle open. Then we smoothly release it and slow down until the power unit stalls. At the same time, do not forget the condition: the gas reducer of the car engine must continue to work. For "dummies" explanation: the engine will not stall completely if you start turning the throttle regulator in an arbitrary direction. If the worst performance of the motor is visible, it will be necessary to change the direction of rotation of the gearbox and restore its stable operation. Hello to all viewers of our channel!

In this review, we disassemble the 4th generation OMVL LPG reducer, which is widely used when installing gas on a car. The main advantage of the reducer is the absence of a membrane between the antifreeze and the gas chamber. For other features, see the overview. Discussion of the video here Buy OMVL reducer here Video Reducer OMVL HBO 4th generation. What's inside and how the HBO TV channel works Very often installed on a car 4th generation gas equipment, users are not happy with the fuel consumption or the vehicle's performance.This forces you to go to the service center for additional LPG adjustment... It's good if the masters understand how to solve the problem. There are situations when driving LPG adjustment there's no point. This happens if the installer's employees do not understand well in principle settings, and it is not uncommon to find a generally absurd opinion - the autotuning of Italian systems solves all problems. No autotuning will make the minimum - so that the car does not at least stall. Rest settings must be carried out manually using diagnostic equipment. It has been said, written many times, and the most important thing is in all instructions for automobile gas equipment - if it is correct tuned HBO 4 generations the petrol injection time remains the same when running on petrol and gas. It is the job of the tuner to make sure that the injection time does not change. HBO... For example, refer to the instructions for gas equipment of the 4th generation OMVL – Fuel card setup... We read from the point 4.4.1 Modify the map. And the rest of the systems are no different. This is the main thing. 1. To configure having only a cable for LPG adjustment by changing the injection time. If you have to use this option, then it is easier to use older versions of programs where there is a rough HBO setting by load. 2. Adjust with the fuel trim diagnostic scanner. If you have a diagnostic scanner or adapter, it will be convenient to configure it with any program. I will clarify what is the load on the engine. For many, an increase in load is an increase in revs. This is fundamentally wrong. If you push the throttle to the floor in neutral, the revs will skyrocket, but the load will be at its lowest. The load is proportional to the injection time, and therefore to the discharge in the manifold (more air is required to burn a large amount of fuel, therefore the vacuum in the manifold is proportional to the load). Favorite section of settings for most installers. In principle, this should always be the starting point. Autocalibration is a fairly simple operation, the control unit remembers the petrol injection time. Switches to gas. And it adjusts the coefficients of the fuel map in order to repeat the petrol injection time on gas. Only there is one big BUT. The whole map is changed according to the data of one cell. That is, for example OMVL changes the entire map of coefficients for the minimum load cell at 3000 rpm. LOVATO changes the whole map at idle. This is necessary for the vehicle to be able to travel for tuning while in motion. There is no question of any 100% setting of all revolutions and the entire load. LPG adjustment by load implies a change in the cells not in terms of revolutions, but in terms of injection time. That is, you memorize the petrol injection time at a certain moment of movement (for example, 3 ms), switch to gas. See how the petrol injection time changes (do not change driving conditions and effort on the gas pedal). Compare with gasoline readings. For example, it turned out 4 ms, but it was 3 ms. This means there was an increase in injection by 33%. If the petrol injection time while running on gas has increased, this means the mixture is poorer than necessary. And it is poorer by 33%. Now we change the entire line of 3 ms to +33 units, and so on throughout the load. Manufacturing companies HBO until about the middle of last year, they closed the odds map in their programs and left only a rough one in the public domain. customization by load. Rough adjustment the load looked like 8 cells, where the coefficients were entered. These factors were applied to the fuel card. The first column of 4 cells was responsible for the idle run. The first cell changed the 1000 revolutions map column from 2 ms to 3 ms; 2, the cell changed from 3.5 ms to 6 ms, and so on. Cells of the second column of coarse adjustments changed the map in all columns except 1000 revolutions. That is, everything except idling. For clarity, I made screenshots of the old version of the program. Program odds map OMVL... I specifically changed all values to 100. Cells settings in terms of load, they were gone with version 6. We introduce correction factors into the rough customization. Let's see what happened to the odds map. It shows well how it works. customization by load. At adjusting in terms of injection time, it will be easier to use exactly the old version of the programs (5.0.5 or 5.0.8). The tuning method discussed earlier is not convenient when tuning in motion. It is very difficult to keep your foot in one position and finding a road with a perfectly flat surface is also not always possible. It was more convenient to record the data and analyze it after disconnecting from the car. First, we record driving on gasoline, then on gas. We compare the injection time. But this is where the difficulty arises. How to compare injection times in different operating modes? To do this, you need to synchronize the data when driving on gasoline with the data when driving on gas according to the readings of the MAP sensor. The MAP sensor shows the collector vacuum. Its readings change as the load changes, but do not change if the coefficient is incorrectly selected in the LPG tuning program. For example, when running on gasoline at idle, you have an injection time of 3 ms, a vacuum of 0.3 atmospheres. Switch to gas, the injection time becomes 4 ms, but the MAP sensor readings do not change and 0.3 atmospheres remains. To use this principle, you need to use the signal registration tab in the setup program (item 6.1 Acquisitions). First, you need to drive about 100 kilometers on gasoline so that the fuel trim is back to normal. Record data when driving on gasoline, save it. Write down what the manifold vacuum is equal to at the injection time used in the HBO program (2, 2.5, 3, 3.5, 4.5 ms, etc.). Record data when driving on gas, save it. In the gas data, look at the MAP readings and use them to determine how long the petrol injection time took. For example, you need to set up a line of 3 ms, see how much MAP is equal to 3 ms when driving on gasoline, for example 0.3. See how much the petrol injection time when driving on gas at MAP 0.3, for example 4 ms. This means that in line 3 ms the mixture is 33% lean, add 33 units. This principle is remarkably implemented in HBO. Digitronik... The program collects data and builds a schedule of work on petrol and gas. It immediately becomes clear where to add, where to subtract. In simple blocks, you can see only load curves - 2D map. In more serious blocks, you see a 3D map, in it you can see the change in injection relative to the load and rpm. Because of this feature, I recommend everyone to use Digitronik control boxes. For their settings only the cable is enough for HBO. For the convenience of processing the recorded data, you can use a spreadsheet processor - Excel or Calc (OpenOffice). I will tell you how to do this in another article. The most correct option is 4 generation LPG adjustment using a diagnostic scanner. The diagnostic scanners show the vehicle ECU fuel trim (FuelTrim). Fuel trim displays the injection deviation from the norm as a percentage. Again, the readings of MAP and MAF sensors and a table of reference values of injection times at certain readings of these sensors are most likely used. When the injection times deviate from the reference, the correction is shifted from 0. For example, the same example with 3ms when running on petrol and 4ms when running on gas. The correction will be 33%. The essence settings according to the diagnostic scanner, it is reduced to the selection of card coefficients in such a way that at any load and speed the correction does not go beyond + -5%. At first, I would recommend adjusting the card only for load, and then see if there is any difference in rpm. Usually it is enough to adjust the load only. The convenience of using the scanner is that you do not need to calculate deviations in your head. It helps a lot with at the construction site in real time. While driving, you see a map of coefficients and fuel trim readings. Enter the correct ratio instantly and watch the car's reaction. If you are using not a full-fledged scanner, but an OBD adapter with a laptop, then the data can also be recorded and processed later.Again, tied to the MAP sensor. I will describe the processing of diagnostic program data in a spreadsheet processor, using Digimoto 5 version as an example, in the future. Every car owner wants to save on fuel, especially in modern conditions. Of course, it is quite possible to realize such an idea if you install gas equipment. Moreover, in specialized reputable services, in which real professionals work, such work is done in a matter of time. Of course, before installing LPG, drivers should be aware of whether propane or methane is suitable as fuel for the engine of your car, whether it can shorten the service life of the internal combustion engine as a whole, etc. As experienced experts say, problems can be avoided only when the owner of the vehicle means will be able to correctly select the equipment - then it will not bring any harm to the motor. Consequently, the owner will be able to save significantly. In addition to installing the unit, it is also necessary to configure it, since the 4th generation HBO setting plays an important role. Wanting to know how to connect 4 generations of HBO with your own hands, how to adjust 4 generations of HBO yourself, you need to carefully study the intricacies of this issue. To set up the hardware, you need some details: the program intended for this; a special cable that will allow connection to the control unit of the unit; diagnostic cable. In order for the 4th generation HBO adjustment to proceed correctly, competently, you need to understand that you will need to choose two options, which, in fact, will allow you to do this. For example, it is always possible to carry out the correct setting of LPG, having only a cable designed to adjust the unit, doing this by changing the injection time. When this option is used, older versions of the programs fit perfectly. You can achieve success with a diagnostic scanner, this is done by fuel correction. Of course, having at hand a diagnostic scanner, an adapter, you can always configure this or that program. It's important to know. It should be understood that the load on the engine is not only about the increase in revs, as many drivers believe. This statement is not at all true, since, accelerating in neutral gear, of course, the revs will soar to the limit, but the load is low. When the correct configuration of the 4th generation HBO is carried out, most specialists often pay increased attention to this section. In general, auto-calibration is a simple action, and in this case the control unit will memorize the petrol injection time. When this option is selected, it is customary here to change the cells, this is done not by revolutions, but solely by the injection time. All that is required is to remember the fuel injection time, this is done at certain moments of movement, after which you need to switch to gas. This is how the 4th generation HBO is configured, the nozzles are adjusted and the work in general. In addition, the 4th generation LPG, namely the adjustment of the pressure reducer, plays an equally important role. It's important to know! As for the working pressure after the auto-calibration procedure, it will be automatically set, and at the same level at which the adjustment is carried out. Regarding the minimum pressure, this is the gas pressure, below which the system will automatically transfer the vehicle to gasoline. Attention: Every driver must understand that the adjustment of the LPG gearbox, as a rule, is required only at the time of the installation of the unit. But after one hundred thousand kilometers, it is necessary to perform diagnostics. It is also possible to service HBO 4 generations with your own hands, but only if you have the appropriate experience, knowledge, equipment that allows you to do this. If you consult with experts, you can find out how to remove HBO 4 generations with your own hands, doing it at home.You always need to know that the competent operation of the unit does not depend on the quality of the electronic setting, as for some reason most car owners think. Indeed, after a certain period of operation, valves and membranes begin to wear out, as a result of which there is an over-consumption of gas. But this unpleasant moment can be postponed if you learn about the intricacies of the correct operation of the equipment. For example, with regard to starting the engine, this should always be done exclusively with the native fuel of the car, which is often forgotten. Only at the moment when the engine temperature reaches thirty degrees, you can switch to gas. This is because the diaphragm of the gearbox freezes in practice at low temperatures. Therefore, the gearbox must be connected to the antifreeze lines, and only in this way. Wanting to adjust the 4th generation HBO gearbox with your own hands, you need to realize in advance that this is not as easy as it seems. Before doing such work, do not forget to warm up the engine, after which you can turn off the gas supply. If there is a need to adjust the sensitivity of the gearbox, then you need to unscrew the sensitivity regulator, and the procedure is performed at the moment when the idle speed does not change. Next, you need to tighten the regulator, check the setting. All that is needed is to press the accelerator pedal - the engine should not react to such an action, respectively, you should notice the absence of delays and jerks. Of course, if you managed to configure the 4th generation HBO on your own, and you did everything in a competent way, then the internal combustion engine will work stably, clearly. Setting up gas equipment is always a difficult procedure, so it is advisable to trust it to experienced specialists who work exclusively in specialized services. Adjusting the gas reducer using various methods 1. Adjustment of the gearbox: what do you need to adjust? 2. Methods of gearbox adjustment Due to the rise in gasoline prices, many car owners began to equip their "iron horses" with gas equipment (LPG) in order to somehow save their finances. However, along with the new equipment, new troubles have appeared - its maintenance and adjustment. Therefore, today we decided to turn to the problem of adjusting the gas reducer. After all, this must be done not only immediately after installing the LPG equipment on the car, but also during the operation of this system. The more the LPG mileage and the period of its operation, the more necessary this adjustment becomes. The fact is that over time, the rubber-technical elements of LPG - valves and membranes - can change their properties, which, in turn, leads to excessive consumption of gas. Of course, such consequences can occur only after 3-4 years of operation (this is about 100,000 km of run), but you should prepare for this in advance. Before you begin to get acquainted with the basic methods by which the gearbox is set up, you need to familiarize yourself in more detail with this device and its main characteristics. After all, it is the gas reducer that plays the most important role in the normal functioning of LPG. What is its main task? It is thanks to this unit that the driver of a car with LPG can lower the gas pressure that comes from the cylinder. At its core, this is a rather primitive pressure regulator that allows you to autonomously maintain the same pressure indicator. But, since nothing in this world is perfect, during the operation of the gas reducer, the pressure can still fluctuate slightly. In practice, it looks like this: when the gas flow rate is stable, the pressure is also kept at a given level, and when it starts to be consumed more intensively, the pressure may drop slightly. While this process is generally safe, you still need to be aware of it. As we already noted in our introduction, the gearbox adjustment is needed during the installation of a new LPG unit on the car, as well as after its long-term operation. But in addition to these factors, the need for the frequency of adjustment and the features of this task is also associated with: - the generation of gas equipment and, accordingly, the gas reducer itself; - the number of regulators that are available on the gas regulator; - the fuel system on which the car engine runs - gasoline or diesel. The gas regulator contains membranes that can freeze at low temperatures. For this reason, the gearbox must be connected to the automotive cooling system. If we talk about the operation of this LPG element as a whole, then it is important to note the following point: it is impossible to start the gearbox simultaneously with the engine. First, you need to wait until the engine temperature rises to 30-50 ° C, and only after that you can start up the gas reducer. The design of a conventional gas reducer is also straightforward. In particular, this device consists of the following parts: - separate chambers, the number of which may vary depending on the type of gearbox (from 1 to 3); - a regulation system that controls the supply of gas from cylinders to the combustion chamber of the engine. But on modern HBO, you can find two types of gearboxes. They have a number of very important differences between each other, which, in particular, has a significant impact on the process of setting them up. Let's consider the features of each of them: 1. Vacuum reducer. To put such a reducer into operation, you must perform a number of mandatory steps: - put the switch in the "Gas-Petrol" position; - turn the key in the ignition lock; When the first two instructions are followed, the required amount of gas is injected into the intake manifold, which will then allow you to start the engine and hit the road without any problems. The same is ensured by the operation of the starter. 2. Electronic device of the gas reducer. It turns on only in the position of the switch to the "Gas" position. Similar to the vacuum reducer, we start the ignition and give the starter the opportunity to work a little until the required amount of gas is collected in the intake manifold and the device itself warms up to the desired temperature. To properly configure the gas regulator, you must understand absolutely everything in its settings. So, a larger number propane type reducers are characterized by two regulators, although there are a small number of models with one. But methane analogs, on the contrary, almost always have only one regulator. It is the correct setting of the gas regulator regulator that is the main problem for car owners. Why are two regulators installed on the gearboxes? The first one is the idle speed regulator. In the process of setting up the device, we will need to screw it all the way. But the bottom one is sensitivity adjuster... It is he who presses the reducer membrane. Having become familiar with this device in more detail, you can go directly to the setup procedure. And to the question of what is needed to set up the gas reducer, the answer will be very simple - you need patience and strict implementation of the instructions below. You should also remember that you will have to work with gas equipment, so all your manipulations should be extremely careful. In the event that you do not feel enough self-confidence, it is best to seek help from a specialized car service. As we have already noted, there are electronic gas reducers and vacuum ones. Setting each of them has its own characteristics and differences, which is why we will consider the methods of adjusting each of them separately. Electronic gas regulator - which setting method should I choose? On this type of device, two types of settings must be applied: 1. Sensitivity adjustment, or pressure setting in the second stage. 2. Adjustment according to the amount of gas that moves through the idle channel. But before proceeding with both, it is necessary to carry out a few more mandatory actions. First of all, we start the car engine on gasoline so that it can preliminarily warm up to operating temperature. In this case, the idle speed is set in the border between 950 and 1000 rpm. When the engine temperature reaches the required level, turn off the gas supply and allow it to work out the remainder. After that, we prepare the car for direct adjustment of the gas reducer: - we turn the power register to the maximum indicator (in the event that a two-chamber dispenser is installed, then we open the first chamber completely, and the second - to a minimum); - turn the idle screw completely, then turn it back exactly 5 turns; - set the sensitivity regulator to the middle position. Well, first of all, let's start setting up the idle speed. To do this, we start the car, but already on gas. Use a choke and bring the engine to 1700-2000 rpm. Next, you need to simultaneously perform two actions at once: remove the suction a little and rotate the idle speed control until you can find the position in which the largest number of starter revolutions occurs. In this case, at the end of this procedure, the suction must be completely removed, and the car must begin to idle stably. After setting the maximum number of starter revolutions using the idle speed regulator, gradually tighten the gas pressure regulator sensitivity regulator. If in the process of performing this procedure the number of revolutions begins to change, again try to bring them to the maximum with the help of the idle speed controller. If you can't do anything with this regulator, try turning the sensitivity screw two turns and repeat the entire procedure from the beginning again. The goal you need to achieve is the maximum idle speed of the starter motor (approximately 1100-1200 rpm), with the sensitivity control turned almost to the end. But it is not recommended to drive at such speeds, since their value should be below the nominal rate. Therefore, we again tighten the idle speed control until the speed drops to 950-1100 rpm. Now let's move on to adjusting the sensitivity of our gas reducer. We also slowly turn off the sensitivity regulator and watch how our actions affect the revs of the starter, which it carries out at idle. When we felt that the number of revolutions began to change, we turn the regulator back a little - about ¾-5/4 turns. Do not forget to also check the operation of the engine, for which sharply press the gas pedal. If you did everything well, he will respond immediately and without jerking. When adjusting the gearbox, it is very important not to forget to adjust the power register. To do this, it is necessary to bring the starter of the working engine to 3-3.5 thousand revolutions per minute, while simultaneously turning the power register regulator. This must be done until the number of revolutions of the starter starts to decrease. To make sure you achieve what you want, try moving the gas meter screw from place to place and unscrew it about ½-3/4 turn from the found position. But do not howl about the fact that there are dispensers that consist of two sections. In this case, all the above actions should be applied only to the first camera, and the second one should be set only by 25-30% of the first. On some gas pressure regulators it is also possible to adjust the pressure in the 1st stage. To carry out the adjustment, it is necessary to completely turn off the engine, block the line through which the gas flows, and connect the pressure gauge to the cavity of the first stage (it is advisable to use a pressure gauge with a scale of 1.5 kgf / cm2, and it is connected through a control hole, which is muffled by a regulator). After that, we open the gas line again, start the engine idling and bring the pressure of the first stage to 0.38-0.42 kgf / cm2. Ideally, after adjusting the power register, it is necessary to re-adjust the idle speed and sensitivity of the gas reducer. Only after that you can proceed to the final configuration stage, which consists of several steps: 1. Step on the gas pedal very sharply. 2. We turn the sensitivity regulator by 0.25 turns until the speed of the revolutions begins to drop very much. 3. We turn off the regulator by 0.5 turns and let the engine run a little, carefully monitoring the stability of this process. What you need to know about setting up a vacuum gas reducer? The setting of vacuum-type gas reducers can also be carried out in two ways: 1. Adjustment of sensitivity and idle speed of the gas reducer can be carried out separately. 2. Adjustment of sensitivity and idle speed of the gas reducer can be carried out simultaneously. As for the first adjustment method, it is no different from the adjustment process of the electronic gas regulator, which we have already described above. For this reason, we will look at how to combine these processes. First of all, we take up idle. To do this, we start the car, but immediately on gas, and not on gasoline. Again, using the suction, we level the engine speed to the amount of 1700-2000 per minute. We slowly remove the suction and, using the idle speed regulator, we achieve the maximum value of the number of starter revolutions (at the end, the suction must be completely removed). With the help of the regulator, we achieve the speed in the range of 1000-1100 rpm and already at the end we set the rate - 950-1100 rpm, screwing the regulator a little more. Setting up the power register of a vacuum reducer is almost the same as setting it up on an electronic prototype. In particular, you need to do the following: - we start the engine at idle speed; - set the intensity to 3000-3500 rpm; - we twist the regulator until the revolutions begin to fall; - we try to adjust the register regulator, trying all values; - turn off the register regulator by 0.5-0.75 turns, and also slightly adjust the idle speed.
