Diesel Injector Nozzle DLLA150P1164 for Bosch 0 433 171 741 0433171741 Injector Nozzles

In this case, cleaning can be carried out in several ways:

With the use of special cleaning additives that are added to the fuel. They contain special cleaning agents that gently clean the nozzle holes.

Pressure cleaning. To do this, you need to accelerate the car to a speed of 110 ... 130 km / h, and drive 10 ... 15 km (about 5 ... 6 minutes) at high engine speeds. Due to the high load in the nozzles, natural cleaning will occur.

Idling. This method is similar to the previous one. it is necessary to start the internal combustion engine while the car is stationary and maintain the speed at the level of 4 ... 5 thousand for 3 ... 4 minutes. This will also clean the nozzles. However, the previous cleaning method is better because the load under its conditions is higher.

Conclusions:

Problems in the operation of the injectors are not a critical breakdown, however, if they occur, we recommend that you do not postpone checking and repairing the breakdown. In most cases, repairs can be carried out independently using the methods described above. Timely check and diagnostics of injectors will allow you to avoid problems with the operation of the car. Prevention will cost you less than repair work on injectors or other internal combustion engine components. We recommend that you clean the nozzles after every 30……35thousand kilometers your car, regardless of its condition.
