Diesel Injector Fuel Injector 0445120327 Bosch for Mwm JAC Pick Truck 4cyl48 EU 5 Engine

The starting injector is checked according to the following algorithm:

1. pick up some small measuring container (like a glass);

2. remove the nozzle from the internal combustion engine and install it in the mentioned container;

3. one contact of the nozzle is connected directly to the car battery, and the other to its “mass”;

4. the fuel pump relay is also connected to the “plus” of the battery, thereby putting it into operation.

During operation and testing of the pump, the nozzles must be turned to the fuel spray angle, as well as the amount of gasoline pumped.   Reference data can be found in the reference information for the injector that is installed in your car.   As an indicative example, data on the K-Jetronic system can be given.   In this case, the spray angle is 80°, and the volume is from 70 to 100 cubic centimeters of fuel per minute.   Naturally, in other systems, these indicators will be different.

After you check the operation of the mono nozzle, disconnect it and wipe it dry.   In normal working condition, its body is sealed.   And this means that fuel should not leak from it.   Wait a while and make sure of this (1 ...   2 minutes is enough for this).
