What is the function of automobile accelerator vacuum tube?

The function of the throttle vacuum tube of Pacific Auto Network is to control the air conditioner governor. After the air conditioner is turned on, the compressor works. In order to keep the engine speed from decreasing, a vacuum tube is used to control the switch of the air conditioner governor.

Golf 2/ Jetta's eight-valve car, as well as the owners of most happy cars, generally feel that the braking effect is not ideal. This is because the diameter of the front brake disc of the above-mentioned models is small and the braking torque is inherently insufficient. In addition, the brake disc is a solid design, and the heat dissipation effect is not good, which will quickly deteriorate the braking efficiency and make the already insufficient braking force worse.

Solution: Of course, 10. 1_ disc used in Passat /Vento2.0 or even1_ disc used in Corrado can be transplanted, but it is too expensive to replace all related components such as caliper bearing seat, so this method is not recommended. The most economical way to improve it is to replace the VentedDisc originally used for GTI to minimize its performance decline, but the overall braking performance will not be greatly improved, which is more suitable for owners who are not satisfied with the original braking performance to upgrade. Only by replacing the ventilation disc with cross drilling holes can the braking performance be completely improved under the same disc diameter and oil pressure. The principle is simple, and the performance can be improved by increasing the wear of the disk. Because of the simple construction, the disc wear will be slightly accelerated, and there will be no negative impact on other components. The price is similar to that of the original box (compared with the original price by Valueparts), which is the improvement method with the highest CP value.
