柴油机工作时要求喷油器化雾的柴油要形成烟雾状，且颗粒越细在气缸内与空气混合就越均匀，燃烧更完全。如果化雾不良，甚至成一条线状，柴油就难以与空气混合，并易喷到活塞顶及缸壁表面上，工作时启动性能差，有敲缸声，耗油多，易积炭等现象。究其原因主要是有的喷油器工作 Diesel engine work requires the injector fog of diesel to form a smoke-like, and the finer the particles in the cylinder and air mixing more uniform, more complete combustion. If the fog is bad, even into a linear, diesel is difficult to mix with the air, and easy to spray to the top of the piston and cylinder wall surface, poor start-up performance at work, there knock knock sound, fuel consumption, easy carbon deposition and so on . The main reason is that some injector work
