What is the function of a car vacuum pump?

The function of the automotive vacuum pump is to generate negative pressure, thereby increasing braking force. For vehicles driven by diesel engines, since the engine uses compression ignition (CI), it cannot provide the same level of vacuum pressure at the intake manifold, so a vacuum pump that provides a source of vacuum needs to be installed.

How much do you know about automotive vacuum pumps?

Many people may look puzzled when they hear this name, what is it? I haven't heard of it! Even those who have some understanding of cars may have only heard of this name, but they don't really know what it specifically does. So today, let's learn about it together! The vacuum pump inside a car generally exists to provide assistance to the vehicle; it is an essential component. For those who are not very familiar with it, for the sake of your beloved car, it is best to understand what this thing does inside the car, what its working principle is, and how to maintain it. Only by understanding it...

A vacuum pump, as the name suggests, is used to create a vacuum, and its function is to generate negative pressure, thereby increasing the braking force. For vehicles driven by diesel engines, since the engine uses compression ignition (CI), it cannot provide the same level of vacuum pressure at the intake manifold, so a vacuum pump is needed to provide a source of vacuum.

The braking system of a family car generally relies on hydraulic transmission as the medium. Compared to a pneumatic braking system that can provide power, it requires an auxiliary system to assist the driver in braking. The vacuum brake assist system can also be called a vacuum servo system.

Working principle of automotive vacuum pump

Working principle of automotive vacuum pump

The working principle of the automotive vacuum pump is that, in vehicles equipped with gasoline engines, the engine generally uses a spark ignition system, which can generate a relatively large vacuum pressure at the intake manifold. This can provide sufficient vacuum source for the vacuum-assisted braking system. However, for vehicles driven by diesel engines, since their engines use compression ignition, they cannot provide the same level of vacuum pressure at the intake manifold. Therefore, a vacuum pump that can provide a vacuum source is needed. Additionally, engines designed to meet certain automotive emission and environmental requirements also require it to provide sufficient vacuum source to ensure the vehicle operates normally. The vacuum pump mainly outputs pressure generated by the power servo system, but when it cannot function properly, the hydraulic system can still be driven manually to provide assistance. The vacuum-assisted braking system can also be referred to as the vacuum servo system. The automotive braking system typically relies on hydraulic transmission as the medium, and compared to a pneumatic braking system that provides power, it requires a resistance system to assist the driver's braking. The automotive vacuum pump mainly utilizes the vacuum generated by the engine during operation to provide sufficient assistance when the driver presses the brake, making it easier for the driver to brake. However, once the vacuum pump is damaged, there will be a lack of assistance, making the brake feel heavier when pressed. Additionally, the braking effect will also decrease, and sometimes it may even fail, indicating that the vacuum pump has been damaged.

The vacuum braking assist system can also be referred to as the vacuum servo system. The automotive braking system commonly used relies mainly on hydraulics as the transmission medium, and compared to a pneumatic braking system that can provide power, it requires a resistance system to assist the driver's braking. The car vacuum pump mainly utilizes the vacuum generated when the engine is running to provide sufficient assistance when the driver steps on the brake, making it easier for the driver to brake. However, once the vacuum pump is damaged, it lacks a certain level of assistance, making the brake feel heavier when pressed. Additionally, the braking effect will also decrease, and sometimes it may even fail, indicating that the vacuum pump has been damaged.
