Womala Engine Crankcase Breather Hose OE 1020944387 for Benz 190 W201

Core Functions

• Crankcase Ventilation: The primary function is to discharge blow-by gas from the crankcase, reducing internal pressure and preventing oil leakage from seals or gaskets.
• Emission Control: Guides blow-by gas back to the intake system for re-combustion, reducing harmful hydrocarbon emissions and complying with environmental regulations.
• Oil Quality Protection: Prevents excessive pressure buildup in the crankcase from diluting engine oil or degrading its lubricating performance, extending oil service life.
