DIY Fiat Ducato nozzle repair

In detail: do-it-yourself Fiat Ducato injectors repair from a real master for the site my.housecope.com.

Today we repaired the injectors and put everything back together. Price tag 28300, not cheap! This fiat costs me a bit dear, but I like it)

Price tag: 28 300 ₽ Mileage: 165,000 km

FIAT Ducato 2010, diesel engine 2.3 l., 110 hp s., front-wheel drive, manual transmission - dealership service

Piznes ... I had to replace the nozzles on the Boxer ... As I presented the cost ... Not only is it about fifty kopecks to buy them, they, curv, need to be entered. Filling in is also not always easy and simple.
Expensive fuel for these devices. They made me a fuel pump and injectors at MAZ for 5600 rubles, Karl, for 5600!

So that's it. In theory, everything was normal. But I was afraid that the forces are pouring and I will burn the engine, because I am worn like mad on it)

A short block for a Ford costs 64t.r
Burned out. Like welding a pancake burns through.

At one time, Fiat was developing its version of the Common Rail system for installation in its cars, however, seeing no prospects in such a system, it sold all the developments to German manufacturers, including the auto giant Daimler and RobertBosch GmbH. Today, all of the company's vehicles running on diesel engines with a Common Rail system are equipped with injectors and systems from Bosch. Common Rail from Bosch is also equipped with a commercial minibus / van Fiat Ducato, let's look at the weak points of CR in Ducato.

Ducato is equipped with both diesel and gasoline power units equipped with fuel injectors. At the same time, in case of any breakdown, except for pollution, gasoline injectors should simply be replaced - it is cheaper and less troublesome,Image - DIY Fiat Ducato injector repair

diesel injectors are a completely different matter, they can be restored, which will save money for the car owner. It is diesel injectors, we will consider them in more detail.

The diesel-powered Fiat Ducato uses injectors (injectors) from Bosch, which, based on the developments of Fiat and Denso, in 1997 released its version of the Common Rail accumulative fuel supply system with injectors equipped with electronic fuel supply control. This system made it possible to make diesel engines more efficient and more economical due to the fact that the fuel supply does not occur directly, but after the accumulation of fuel in the CR fuel accumulator, which made it possible to increase the fuel supply pressure.

At the same time, good maintainability resulted in lower reliability than the same CR system from the pioneer Denso. Bosch injectors are made up of elements such as:Image - DIY Fiat Ducato injector repair

It is worth remembering that most often the multiplier fails, which in most cases is replaced with a new one, the nozzle is replaced every 140-160,000 km of run, and the ball must be changed in any case when the nozzle is reassembled.
To date, Bosch has developed schemes for both repair and replacement of injectors in its systems, and our car service strictly adheres to the basics of recommendations, carrying out diagnostics and repair operations on special bench equipment.

Fiat Ducato is a fairly large and heavy car that is equipped with powerful engines. Basically, diesel units with a Common Rail fuel supply system are installed in this car. To ensure high performance, the nozzle pressure increased from 1300-1400 bar in 1997 to 1800-2100 bar in 2010. This increase in pressure resulted in an increase in productivity and in the number of breakdowns. In recent years, Bosch has been actively improving the environmental friendliness of its CR system, which also affects durability. An increase in pressure leads to the fact that often the fuel simply does not come out completely from the injector, remaining there, starting the corrosion processes, in this regard, it is worth highlighting the following main malfunctions of Fiat Ducato injectors:

  • an increase in the amount of fuel consumption;
  • reduced traction;
  • problems when starting the motor;
  • the movement of the vehicle is jerky.

Among the most common causes of breakdowns, it is worth highlighting the following:

  • damage to the elements of the fuel line;
  • clogging with fuel residues;
  • natural wear, leading to a decrease in tension between the nozzle elements.

All of the above causes of breakdowns lead to such unpleasant consequences as:

  • incomplete closing of the system after the process of supplying fuel to the cylinder;
  • overheating of the power unit;
  • violation of pressure regulation;
  • depressurization.

In any case, the repair of the fuel system should be carried out by professionals at an authorized service station or SC.

The fuel system is a rather complex organ of a car, however, it always transparently hints to the owner about problems that have arisen inside it with the help of sounds in the engine when driving, the presence of smoke or burning, an increase in fuel consumption, etc. To prevent all these signs of poorly working fuel systems, you need to bring a car for diagnostics 2, or better 3 times a year.

Diagnostics consists of the following steps, including:

  • partial disassembly of the power unit;
  • dismantling of injectors;
  • inspection of injectors for defects and damage;
  • diagnostics on bench equipment: measurement of injection pressure, check for leaks.

Repair of injectors can be carried out in different ways - it all depends on the type of breakdown and the number of operations required to carry out the repair.

In our car service, they can carry out such repair and restoration work of injectors as:

  • troubleshooting;
  • replacement of springs and spacers;
  • cleaning the sprayer;
  • replacement of the atomizer;
  • setting and adjusting pressure;
  • replacement or restoration of the solenoid.

The injector is not repaired if:

  • the plunger cannot be removed;
  • there is no analogue of the atomizer;
  • there is severe mechanical damage.

Cars change, friends and the forum remain. [my.housecope.com/wp-content/uploads/ext/1209]
