VE pump parts manufacturers to introduce the electronic control VE pump structure and principle:

When the diesel engine is running, the crankshaft gear drives the transmission shaft of the distribution pump. The sliding vane type oil pump at the front of the diesel oil tank extracts the diesel oil from the oil tank, passes through the diesel filter and the oil-water separator, filters out the impurities and water in the diesel oil and then enters the oil pump, making the diesel oil pressure rise. Then into the distribution pump body, and then through the solenoid valve into the plunger cavity. When the plunger moves upward, the compressed diesel generates high pressure, which is distributed to the corresponding cylinder oil passage on the pump body through the oil passage and the oil outlet hole in the plunger, and then through the oil outlet valve, the high pressure tubing and the injector to spray into the corresponding cylinder. Excess diesel oil in the pump body is returned to the tank through an overflow valve on the top cover. The diesel oil circulation can not only take away the heat generated by the air bubbles in the oil path and the friction between the parts, but also lubricate the moving parts. At the same time, the diesel pressure in the pump body controls the advance device and changes the injection advance Angle accordingly.
