高压燃油泵、高压油泵

产品介绍

高压燃油泵是缸内直喷发动机、电喷汽车燃油喷射系统的重要零部件之一；由于缸内直喷发动机更容易产生积碳，所以需要高压燃油泵进一步提高喷射压力，使燃油雾化更加细致，真正实现精准地按比例控制喷油并与进气混合，燃烧更充分，让热效率达到最高，让发动机更加有劲道，同时排放更加低碳，环保出行。

高压燃油泵是汽车缸内直喷技术的关键组成部分，在低压油泵将燃油送到高压油泵之后,高压油泵通过凸轮轴带动,内部则双头或者三头凸轮加压，高压油泵可以将汽油加压到15-40兆帕的压力(这是普通汽油泵压力的三四十倍)，并将高压油通过高压油管送入燃油共轨。

The high-pressure fuel pump is one of the important components of the fuel injection system in direct injection engines and electronic fuel injection vehicles; Due to the tendency of direct injection engines to produce carbon deposits, a high-pressure fuel pump is needed to further increase the injection pressure, making the fuel atomization more precise, truly achieving precise proportional control of fuel injection and mixing with the intake air for more complete combustion, maximizing thermal efficiency, making the engine more powerful, and emitting lower carbon emissions for environmentally friendly travel.

The high-pressure fuel pump is a key component of direct injection technology in automotive cylinders. After the low-pressure fuel pump delivers fuel to the high-pressure fuel pump, the high-pressure fuel pump is driven by a camshaft and pressurized internally by a double or triple cam. The high-pressure fuel pump can pressurize gasoline to a pressure of 15-40 megapascals (which is 30-40 times the pressure of a regular gasoline pump) and send high-pressure fuel through a high-pressure fuel pipe to the fuel common rail.
