What is the function of the Wuling PVC valve?

The Wuling PVC valve primarily serves the function of oil-gas separation. Below is an introduction to relevant knowledge about the Wuling Zhiguang: 1. Power: The 2020 Wuling Zhiguang is equipped with a 1.2L naturally aspirated engine, delivering a maximum power of 56 kW and a maximum torque of 108 Nm. 2. Dimensions: Taking the 2020 Wuling Zhiguang 1.2L Utility Model (National VILS) as an example, its dimensions are 3797 mm in length, 1510 mm in width, and 1820 mm in height, with a wheelbase of 2500 mm and a fuel tank capacity of 38 liters.
This PCV valve on the Wuling vehicle is actually a key component of the engine crankcase ventilation system. I've been driving Wuling for cargo delivery for seven years. It functions like a regulating valve, specifically responsible for controlling gas flow in the crankcase. During engine operation, some exhaust gases leak into the crankcase. If these gases aren't promptly removed, they can increase crankcase pressure - at best causing oil leaks that dirty the engine compartment, at worst damaging oil seals. The PCV valve draws these gases into the intake manifold to be reburned, maintaining proper pressure. If it gets clogged or fails, you'll notice increased fuel consumption, slight shaking during cold starts, and blue smoke from the exhaust pipe. I just helped a friend replace his valve last week, which solved the problem. I recommend checking it every 40,000 km - after all, a new valve only costs a few dozen yuan.
Speaking of Wuling's PCV valve, it's equivalent to the engine's respiratory system. It's installed on the valve cover and connected to the intake system with a hose. Its main function is to recycle exhaust gases from the crankcase: the exhaust gases that leak down during engine combustion are drawn back into the combustion chamber through this valve for secondary combustion. This not only prevents excessive crankcase pressure from causing oil seal leaks but also avoids fresh engine oil being contaminated and degraded by exhaust gases. Once, my car was inexplicably burning oil, and the experienced mechanic found it was due to a damaged diaphragm in this valve. Now, during every maintenance session, I ask the mechanic to clean it with carburetor cleaner. After all, Wuling vehicles often carry loads over long distances, so extra attention should be paid to the maintenance of these wear-prone components.
