You are welcomed to come to our factory to buy the latest selling, low price, and high-quality Powder metallurgy parts in brake booster vacuum pump. Vehicles equipped with gasoline engines, because the engine adopts ignition type, can generate high vacuum pressure in the intake manifold, which can provide sufficient vacuum source for the vacuum booster braking system. Most of the current vacuum pumps are connected to the intake manifold place. Gasoline direct injection engines designed to meet high emission environmental protection requirements cannot provide the same level of vacuum pressure at the intake manifold to meet the requirements of the vacuum brake booster system, so a vacuum pump needs to be installed.
