Where is the car PVC valve located?

[LaAnthony]

In the crankcase. Specific introduction is as follows: The main purpose of the PVC ball valve: Used to cut off or connect the medium in the pipeline, and can also be used for the regulation and control of fluid. The fluid resistance is small—the ball valve has the smallest fluid resistance among all valve types, and even the reduced-diameter ball valve has relatively low fluid resistance. Extended information: Precautions: Disassembly and decomposition of the multi-way valve should be carried out in a clean indoor environment, and the floor should be sprinkled with water before disassembly. During normal engine operation, a portion of the combustible mixture and exhaust gases will inevitably leak into the crankcase through the gap between the piston, piston rings, and cylinder wall. These gases are at high temperatures and carry fuel molecules and other impurities. Under high temperatures, the engine oil will gradually oxidize, deteriorate, and become diluted. The entry of these gases into the crankcase increases the internal pressure, leading to oil leakage faults in seals and gaskets. Therefore, it is essential to promptly discharge the gases that have leaked into the crankcase.
