1.Rotor distribution fuel injection pump. It is characterized by the rotation of advanced rotors to achieve fuel pressurization and distribution. This kind of pump is characterized by small size, light weight, low cost and easy to use, and is generally used in automotive diesel engines.
2. Fuel injection pump – injector. It is characterized by the integration of the injector of the cross-injection pump, and the production of high pressure diesel oil and the regulation of the amount of diesel oil are completed in the injection pump – injector. This type of pump is used in two-stroke diesel engines.
3.PT pump. The characteristic of its oil supply is to adjust the amount of oil supply according to the relationship between pressure and time, the adjustment of the amount of oil supply is carried out in the diesel pump, and the production of high pressure diesel oil and timing injection are completed in the injector. For example, Cummins NH-220 diesel engine is equipped with PT pump.
4. Plunger fuel injection pump. The plunger type fuel injection pump is characterized by the reciprocating movement of the plunger in the plunger sleeve for oil absorption and oil pressure, and the adjustment of the oil supply of each cylinder is achieved by changing the effective stroke of the plunger oil supply. This kind of pump has the advantages of compact structure, reliable operation and convenient debugging and maintenance, so it has been widely used.
