China wholesale Auto Engine Water Pumps Manufacturer – HINO W04D/WU342 29300-78080/29300-E0070 Auto parts Vacuum pump – Xinli

The function of the automotive vacuum pump is to generate negative pressure and thus increase braking power. The output of the vacuum pump is mainly the pressure generated by the power servo, but when it is not working properly the hydraulic system can still be assisted by a human drive. For diesel engine driven vehicles, the same level of vacuum pressure cannot be provided at the intake manifold due to the compression ignition CI of the engine, so a vacuum pump needs to be installed to provide a source of vacuum. The working principle of the automotive vacuum pump is as follows: firstly, in vehicles with petrol engines, which generally use an ignition engine, a relatively large vacuum pressure is generated at the intake manifold, which can provide a sufficient vacuum source for the vacuum power braking system
