The crankcase ventilation filter is an important component in an engine, mainly used to control the gas emissions inside the crankcase to prevent air pollution and protect the normal operation of the engine. The following is a detailed introduction to the crankcase ventilation filter:

The function of the crankcase ventilation filter
Prevent engine oil from deteriorating: Gases in the crankcase (such as unburned fuel gas, water vapor and exhaust) will dilute the engine oil, leading to a decline in its performance. The ventilation filter helps reduce the accumulation of these gases, thereby protecting the quality of the engine oil.
Prevent leakage of oil seals and sealing parts: Excessive pressure inside the crankcase can cause damage to oil seals and sealing parts, thereby leading to oil leakage. The ventilation filter prevents this from happening by regulating the pressure inside the crankcase.
Reduce emission pollution: If the exhaust gas in the crankcase is directly discharged into the atmosphere, it will cause environmental pollution. The ventilation filter introduces these exhaust gases into the intake pipe, allowing them to reignite and thereby reducing pollution.
Improving combustion efficiency: By reintroducing the exhaust gas from the crankcase into the combustion chamber, the ventilation filter helps to enhance combustion efficiency and reduce fuel consumption.
