The function of oil catch tank is to prevent the evaporating oil flow back to the intake manifold to decrease the carbon left in the car. To let the un-burned fuel can come back to the cylinder to avoid air pollution. Oil catch tank may recycle the waste oil gas which doesn’t completely burn to avoid re-burning, decrease carbon accumulation and promote the response of ignition system. Not only protect the environment but save the oil. The base of oil catch tank has designed the detachable screw and no filter inside, so it’s very easy to clean and never accumulate any dirt.
