What is the PVC valve in a car?

1 Answers

07/29/25 6:03pm
The PVC valve in a car is a component of the Positive Crankcase Ventilation (PCV) system on the engine. Its main functions are: to direct gases from the crankcase into the intake manifold through the PCV valve, and to allow a small amount of air to enter the intake manifold directly from the air filter via the PCV valve. Additional information: If the PVC valve malfunctions, it can affect the car in the following ways: the engine may shake during operation, idle unevenly, and emit large amounts of white smoke from the exhaust pipe. Since it is located in the crankcase, a faulty PVC valve can cause internal corrosion, accelerate wear, and further shorten the engine's lifespan.

Do You Need to Press the Brake When Shifting to S Mode in an Automatic Transmission?

Shifting to S mode in an automatic transmission does not require pressing the brake. The methods for using S mode are: 1. Use it during short-distance competitive races; 2. Use it when going uphill, overtaking, or driving on uneven roads; 3. Use it when stronger traction is needed. When shifting into S mode, the engine speed increases, and the transmission delays upshifting while downshifting earlier, enhancing the vehicle's power performance. An automatic transmission does not require the driver to manually shift gears; the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. The starting steps for an automatic transmission car are: 1. Move the gear selector to the predetermined driving position before pressing the accelerator pedal; 2. Avoid pressing the accelerator abruptly; instead, press it slowly to accelerate gradually.

This means an electric motor is added between the engine output and the transmission input, enabling different operating modes such as pure electric and hybrid. 2.
