Does Elysee crankcase ventilation pipe have a one-way valve?

Function of check valve: 1. The exhaust gas in the crankcase is introduced into the intake manifold to reduce the harmful gas in the air exhausted by the engine.

2. Keep the pressure in the crankcase below atmospheric pressure to reduce engine oil leakage.

3. Keep the crankcase ventilated and engine oil fresh.

In addition to the ventilation function of the one-way valve in the crankcase, the one-way valve also has a certain relationship with fuel saving. If the engine oil in the crankcase becomes dirty and blocks the check valve, the vacuum degree of the intake manifold will increase with the increase of the throttle opening, so the air velocity at the throat of the carburetor will increase, the oil output of the fuel injector will also increase, and the fuel consumption will also increase.
