Common Rail Valve F00VC01519 Alen----(at)----china-lutong---(dot)----net Common Rail injectors Common Rail injectors make possible fine electronic control over the fuel injection time and quantity, and the higher pressure that the common rail technology makes available provides better fuel atomization. In order to lower engine noise, the engines electronic control unit can inject a small amount of diesel just before the main injection event (pilot injection), thus reducing its explosiveness and vibration, as well as optimizing injection timing and quantity for variations in fuel quality, cold starting and so on. The 3rd generation of Common Rail makes diesel engines even cleaner, more economic, more powerful and quieter. The key is the innovative injection system: it works with rapid switch, compact piezo-inline injectors.
