Q
what causes blow by in a gas engine
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Blow by in gas engines is primarily caused by the wear and tear of engine components over time, leading to gaps through which gases can escape. Key factors include worn piston rings, cylinder walls, and valve seals. Normally, during combustion, high-pressure gases are contained within the engine's cylinders. However, when components like piston rings and cylinder walls are worn or damaged, they cannot seal properly. This allows the combustion gases to "blow by" the piston and enter the crankcase. Once in the crankcase, these gases can mix with the engine oil, leading to reduced lubrication, increased oil consumption, and potential engine overheating. Regular maintenance and timely replacement of worn parts can mitigate blow by and prolong engine life.

The wear of the piston rings and cylinder walls in a gas engine leads to air loss. Excessive oil may cause air loss. This wear causes a small gap in the combustion chamber that allows pressurized gases to escape or blow out into the crankcase. A defective crankcase forced ventilation PCV system may also cause air to escape. as may altering engine performance to increase pressure. If the engine is not properly maintained. altering engine performance may also cause air loss.
