Chang 'an Auchan X70 nozzle position

The fuel injectors are located in the intake manifold or cylinder head.

The fuel injector is a simple solenoid valve. When the electromagnetic coil is energized, the needle valve is sucked up, and the fuel that opens the nozzle is ejected at a high speed through the annular gap between the shaft pin at the head of the needle valve and the nozzle, forming mist, which is beneficial to full combustion.

The cleaning method of the nozzle is:

2. Find the oil inlet and return pipes of the engine;

4. Connect the oil inlet pipe with the oil outlet pipe of the cleaner;

5. Open the fuel tank cover and switch the oil pump safety to stop the oil pump.
