Function:During engine operation, a portion of the mixture in the combustion chamber will enter the crankcase through the gap between the piston rings and the cylinder wall. This incoming mixture contains unburned fuel, water vapor, and exhaust gases, which, if not discharged in a timely manner, will result in increased pressure in the crankcase, affecting the normal operation of the engine. The positive crankcase vent hose directs these exhaust gases to the intake system to rejoin the combustion, thus lowering the pressure inside the crankcase.
