The nozzle is a pair of precision couplings. The accuracy of the fuel injection unit is relatively high. If the service is not maintained properly or the engine burns normally, it will lead to the serious coke deposition of the North Baotou Mercedes Benz parts and make it burn or block. To prolong the service life of the nozzle, it must be done:

(1) the use of fuel must be clean.

(2) the injection pressure and advance angle adjustment of the injection pump of the Mercedes Benz parts in the north of Baotou must be in accordance with the requirements.

(3) timely maintenance and removal of the coke on the injection nozzle of the Mercedes Benz parts in the north of Baotou, check the injection pressure, the quality of atomization, and ensure the suitable atomization cone angle.

(4) when cleaning and maintenance, we must pay attention to cleaning, and do not swap the pair of needle valves and seats paired with each other.

(5) when the injector is installed, the mutual position of the injector and the combustor must be ensured, and the gasket or the gasket should not be added.
