The quality of nozzle holes affects directly the combustion and injection performance of a diesel engine. 喷油嘴喷孔加工质量直接影响发动机的燃料喷射和燃烧性能。
Electrical pulses pass through the injector winding, and set up a magnetic field that draws the plunger and valve away from the nozzle seat. 脉冲很快，电脉冲通过注油器缠绕，并建立了一个磁场，吸引着柱塞阀原理喷油嘴座。
