Where is the PCV valve located on the Baojun 730?

The PCV valve of the Baojun 730 is located inside the crankcase. Here are the specific details: 1. Function of the PCV valve: At the end of the engine's combustion process, some unburned mixture leaks into the crankcase from the piston rings under high pressure. These blow-by gases can escape into the atmosphere, causing pollution. If these gases are not removed, they can dilute the engine oil in the crankcase, leading to oil degradation and premature wear of engine components. Therefore, a PCV valve is installed on the valve cover to allow these exhaust gases to re-enter the engine through the intake manifold for re-combustion. 2. Working principle of the PCV valve: The PCV valve is controlled by vacuum. When the engine is idling, the intake manifold has vacuum, which causes the plunger to be directly sucked against the spring force, preventing the exhaust gases from flowing. At high speeds, the spring force holds the plunger in place, also preventing the exhaust gases from flowing. At medium speeds, the vacuum suction from the engine's intake manifold overcomes half of the spring force, causing the plunger to wobble within the valve body, allowing the exhaust gases to start flowing into the intake manifold.
