What is a PCV heater?

The PCV heater is a heater for the PCV valve, which is a valve of the crankcase ventilation system. PCV radiators are used to prevent pipes from freezing, and all car engines are equipped with forced crankcase ventilation systems. When a car's engine is running, gases pass through the piston rings and enter the crankcase. The forced crankcase ventilation system can exhaust the gases present in the crankcase into the intake manifold, so that this part of the gas can again enter the combustion chamber to participate in combustion. This will not only prevent environmental pollution, but also prevent excessive pressure in the crankcase. The forced crankcase ventilation system is very important for the engine.
