Injection valve

effect
1. Increase oil pressure (constant pressure): Increase the injection pressure to 10MPa～20MPa.
2. Control the fuel injection time (timing): fuel injection and stop fuel injection at the specified time.
3. Control the amount of fuel injection (quantitative): According to the working condition of the diesel engine, change the amount of fuel injection to adjust the speed and power of the diesel engine. 
Require
1. The fuel is supplied according to the working order of the diesel engine, and the fuel supply of each cylinder is even.
2. The fuel supply advance angle of each cylinder should be the same.
3. The oil supply duration of each cylinder should be equal.
4. Both the establishment of oil pressure and the stop of oil supply must be rapid to prevent the occurrence of dripping.
