摘要
本文从发动机沉积物生成的因素及其影响规律出发,提出控制沉积物生成的技术措施。通过对某辆汽油车进行的道路试验表明:汽油清净剂控制PFID(喷油嘴沉积物)、IVD(进气阀沉积物)、CCD(燃烧室沉积物)的生成效果明显。因此认为,依据清净剂及其加剂汽油的技术方法减少发动机沉积物形成是可行的。
In this paper, based on the factors of engine sediment formation and its influence laws, the technical measures to control sediment formation are put forward. The road tests conducted on one gasoline vehicles showed that the gasoline cleaner controlled the production of PFID(nozzle sediment), IVD(intake valve sediment), and CCD(combustion chamber sediment). Therefore, reducing engine sediment formation based on the method of cleaning agent and gasoline is feasible.
