What is the purpose of an oil-gas separator?
1 Answers
Oil-gas separator is used to separate engine oil from the gases discharged by the crankcase, reducing the emission of engine oil from the crankcase breather to the outside of the engine. The oil-gas separator is commonly known as the exhaust valve, and some people also call it the pressure control valve. The following is the principle of the oil-gas separator: The working principle of the oil-gas mixture is mainly based on the density difference between oil and gas. After the oil-gas mixture enters the separator through the inlet pipeline, it is sprayed onto the oil baffle cap. The diffused oil slides down along the pipe wall to the lower part of the separator by gravity and is discharged through the oil discharge pipe. At the same time, the gas rises due to its low density, changes its flow direction upward through the separation umbrella, and adheres the small oil droplets in the gas to the umbrella wall, which then gather and flow down along the wall.
