The cause of air leakage in the sealing ring of the nozzle, the manufacturer of the sealing pad of the nozzle will introduce it to you:

1. Due to impurities adhered when cleaning or assembling fuel nozzle couplings, the working hour hand valve is stuck, resulting in poor atomization of fuel injection;

2. Improper adjustment of the fuel injection pressure of the fuel injector leads to poor atomization of the fuel injection;

3. The fuel injector is installed on the engine, and the cylinder leakage is caused by the lack of sealing washer, uneven sealing washer or the failure to tighten the fuel injector fastening nut according to the technical requirements.
