The performance of the MAN engine directly depends on the condition of the fuel system. The main role in this system is played by injectors, which depend on the correct injection of fuel into the combustion chamber.

Quite often MAN trucks are operated in difficult conditions and, as a result, the injectors get worn out, their performance deteriorates. Given the low quality of domestic solar power, this is happening faster than we would like. As a result of mechanical damage to the fuel system, the fuel pressure in the rail falls below the permissible level.

And we observe such variants of the machine:

• When loading, CHECK lights up and the truck enters emergency mode (TRACTION FALLS strongly).

• The car begins to START BADLY (with more severe damage to the system).

• The car works unevenly, it can smoke both black and light smoke.

• Sometimes fuel consumption increases.

If you find such defects, you should NOT immediately remove the injectors, as many do. It is at this moment of inspection that you can significantly save your time and expenses for car repair. How to do it?(//tractor-service.com)

SIMPLE ALGORITHM: repair of MAN trucks always begins with diagnostics, during which we pay special attention to such a parameter as the efficiency of the pressure regulator (dosing unit).

We usually face two variants of events:

OPTION 1. During diagnostics, it was determined that the efficiency of the dosing unit is more than 25%. In this case, there is a high probability that the dosing unit is covered (even severely damaged nozzles will not give such an indicator) and here it will be more reasonable to start the repair with the replacement of the dosing unit.

And if, after replacement, the duty cycle has reached 7-8%, the car can drive. This approach greatly saves your time and finances (the cost of the dosing unit is usually around 100 u.e.).

OPTION 2. The dosage efficiency is about 17%. Here, if possible,check the drain returns from the block. If the return is greater than the norm, we remove the injectors and send them in for repair. If the return from the unit is in order, then we look at the dosing unit and the emergency valve.

Most often, with such a percentage, the nozzles are already damaged and require repair. We MUST check the condition of the fuel supply fittings (see the figure) - their damage at the point of contact with the injector will lead to a serious drop in fuel pressure.

If you have option No. 1, you are LUCKY and the repair will end with the replacement of the pressure regulator and several hours of operation. If, after all the procedures, you need to carry out a competentrepair of the nozzles, contact us - we have extensive experience working with these nozzles and adequate prices.

Depending on the volume of work, the cost of repairing the nozzle will be from UAH 800 to UAH 2,800. Repair of the MAN nozzle is guaranteed.
