High Quality New Diesel Fuel Injection Pump Head Rotor 096400-0232 VE Head Rotor for Fuel Pump Engine Spare

1, working principle
(1) The plunger is driven by the transmission mechanism and reciprocates in the pump body. When the plunger moves upward, the volume of the inlet chamber of the pump body increases, generating negative pressure, and the fuel is sucked into the inlet chamber; (2) When the plunger moves downward, the inlet chamber of the pump body increases, generating negative pressure, and the fuel is sucked into the inlet chamber.
(2) When the plunger moves downward, the volume of the oil outlet chamber of the pump body decreases and the oil pressure rises. When the oil pressure reaches the opening pressure of the oil outlet, the oil outlet valve opens, and the high-pressure fuel is delivered to the injector nozzle.
Injector nozzle will be high-pressure fuel mist sprayed into the engine combustion chamber, mixed with air combustion to produce power.
2、Maintenance and precautions
(1) Regularly check the sealing performance of the pump head and the working condition of the fuel outlet to ensure the sealing of the fuel system and the quality of fuel injection; (2) Regularly clean and maintain the pump head to avoid impurities in the fuel and water damage to the system head; (3) Pay attention to check the pump head's transmission mechanism is flexible and reliable, to ensure that the pump head's normal operation. In summary, the diesel engine pump head is one of the key components of the diesel engine fuel system, its structure and performance on the engine efficiency and fuel economy has an important impact. Therefore, it should be emphasized in the process of use and maintenance.
