Diesel EnginePreheating System
1. Necessity of preheating system
At a cold engine starting, the compression heat escapes from the compression chamber even if there is adequate compression. In some cases, the injected fuel does not Read more Diesel EnginePreheating System
Fuel dribble (dripping) after injection
This occurs when the fuel supply is not precisely cutoff at the end of fuel injection and fuel particles are accumulated on the tip of the nozzle. If fuel dribble occurs after fuel injection, the fuel Read more Fuel dribble (dripping) after injection
