What does a vacuum-assisted braking system mean?
1 Answers
Introduction to the meaning of vacuum-assisted braking system: Gasoline engines can generate high vacuum pressure in the intake manifold, while diesel engines and direct-injection gasoline engines require the installation of a vacuum pump to provide the vacuum source, meeting the requirements of the vacuum-assisted braking system. Below is an introduction to the principle of the vacuum-assisted braking system: 1. The brake booster utilizes the principle of the engine drawing in air during operation to create a vacuum on one side of the booster, generating a pressure difference compared to the normal air pressure on the other side. This pressure difference is used to enhance the braking thrust. 2. Even if there is only a small pressure difference on both sides of the diaphragm, due to the large surface area of the diaphragm, it can still generate a significant thrust to push the diaphragm toward the side with lower pressure.
