DIY nozzle repair ford kuga diesel

The injectors in this system are controlled by an electronic control unit using a piezoelectric element or a magnetic solenoid. Thus, they are divided into electromagnetic and piezoelectric. Modern injector mechanisms use six to nine fuel injection phases. Almost all diesel vehicles today are equipped with this system.

The advantages of Common Rail over classic diesels are that the function of creating high fuel pressure and its injection into the cylinder are separate. This made it possible to smoothly regulate the pressure, volume and moment of injection, which led to an increase in engine power, a decrease in the amount of exhaust gases, a compact system, a decrease in noise and an economical fuel consumption (up to 20%).

The most common causes of Common Rail diesel injection malfunctions can be the wear of the moving parts of the diesel injection elements (high pressure fuel pumps, fuel injectors, fuel pumps) due to long-term operation or their premature wear when refueling and running the engine on low-quality fuel.

21 Feb 2017 The experience of operating diesel cars Ford Kuga shows that beliefs about the key value of injectors in cars are slightly exaggerated. On the other hand, many motor malfunctions are associated precisely with the contamination of this unit. But this does not mean that contamination of the injectors is the only possible malfunction. Problems often arise from loss of compression and failure of glow plugs. But below in the article, we will focus on the nozzles - the features of their work and the principles of replacement.

In case of correct operation, the injector ensures that there are no malfunctions in the functioning of the engine, reduced fuel consumption, no problems with dynamics, maintaining a safe temperature regime, and so on. As a rule, owners of diesel variants of Ford Kuga begin their inspection in winter, when the issue of high-quality cranking in difficult conditions is most important.

So, the diesel mixture ignites when the temperature reaches 350-400 degrees Celsius. If the engine is worn out, and the injector does not fulfill the task assigned to it (that is, it does not provide normal air atomization), then the diesel engine will not start.

For this reason, the manufacturer recommends replacing the nozzles every 60,000 kilometers, while the "native" parts are capable of moving at least 200-300 thousand kilometers. If necessary, then periodically it is worth removing the nozzles for inspections. In this case, the cleaning of devices should be carried out on special stands and using a specialized tool. It is forbidden to use various "fumki", sealants and other products, because the fuel mixture will still leak.

But here there is another obstacle, in order to check or replace the injectors on the Ford Kuga, they will have to be removed. And here already beginners may have a number of unforeseen problems. To avoid complications, below we will consider a detailed technique for dismantling the injectors.

To dismantle the injectors, proceed as follows:

• Dismantle the intake pipe then lower the eight fuel injector cap nuts. At the end of this manipulation, dismantle the tubes by freeing them from the clips. In order to prevent accidental scrolling of the injectors when loosening the nuts, support the injectors with a regular wrench. At the same time, be careful - it is important to avoid getting dirt into the system;

• Dismantle the injector return line by separating it from each individual node. Then unscrew a pair of bolts holding the nozzles and remove the products;

• Remove the seal rings and injector guides then install new rings for sealing the injectors;

• Mount the injectors and tighten the retaining bolts by hand. Then connect the return line to the injectors and install new fuel pipes. Place the new fuel pipes of the injectors here, securely fixing them in special clips. After that, pull the pipe union nuts by hand;

• Stretch the injector mounting bolts. When doing this, follow the recommendations for broaching. According to the manufacturer, the force should be 4 N * m, after which the nuts reach another 45 degrees;

• Stretch the flare nuts securing the fuel lines to the injectors. Here the moment should be 19 N * m, and in the second stage the force should be 30 N * m. In order to exclude the scrolling of the nozzles, it is worth using an open-end wrench;

• Remove air from the system , which supplies fuel, and then put the intake pipe in place.

When removing injectors on Ford Kuga cars with a Euro-5 engine, the procedure should be as follows:

• Discard the "negative" conductor from the voltage source in the car;

• Remove the front cowl grille;

• Twist a couple of bolts and disconnect the container with the brake compound from the panel. Then unscrew the five screws and dismantle the panel in the direction of the arrow;

• Dismantle the top cover on the motor;

• Loosen the clamps and remove the tube. Then unscrew the three mounting bolts (those that hold the casing) and remove it from the four retaining clips (located at the back). Next, dismantle the casing itself;

• Slip on four union nuts (hold the tubes on the nozzles), then unscrew two pairs of union nuts. The latter attach the fuel pipes to the distribution line. After dismantling the pipes, it is forbidden to reuse them - throw away the products and install new ones;

• Separate the electrical wiring connectors. This must be done on each of the nozzles. At the same time, separate the connector of the pressure sensor in the fuel supply line. Release the wiring from the three clips and remove it so it does not get in the way;

• Discard the air tubes (fixed in five places) and dismantle all hoses (there are four of them);

• Loosen the bolts and remove the injector retainers. Next, remove the devices themselves and the sealing rings;

• Replace with new guides and O-rings. Perform further work in reverse order. Use new fuel pipes. During installation, first pull by hand, then with the right moment. This option avoids accidental misalignment or incorrect installation.

Removing injectors from a Ford Kuga for repair or subsequent cleaning is not an easy job. It requires a certain amount of attention, experience, knowledge of the sequence of actions and the availability of parts on hand for replacement. If any of the above components is missing, then it is recommended to contact knowledgeable specialists.

Come to our service station. We know Ford cars, have been working with them for a long time, we have a wide selection of original spare parts for replacement. After removing the nozzles, our masters check them for serviceability and clean them using specialized equipment (if necessary). With us, you are always confident in your car and the maximum engine resource.

Ford Kuga 2.0 diesel, 2008 onwards, mileage of about 300,000 km, according to the client on the way, it smoothly lost its tega, then completely stalled. scrolling with a starter jumps from 7 to 22 MPa, the diesel particulate filter is removed, the timing has checked everything by the marks, the car is working on the air, poke in the right direction all ideas are over
