Function and requirements of fuel injectors

Effect
1. Increase oil pressure (constant pressure): Increase the injection pressure to 10MPa~20MPa.
2. Control the fuel injection time (timing): Inject and stop fuel injection according to the specified time.
3. Control the fuel injection quantity (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.
Requirement
1. Supply oil according to the working order of the diesel engine, and ensure that the fuel supply to each cylinder is uniform.
2. The oil supply advance angle of each cylinder should be the same.
3. The fuel supply duration of each cylinder should be equal.
4. The establishment of oil pressure and the cessation of oil supply must be rapid to prevent the occurrence of dripping and leakage.
