Crankcases and PCV Valves

Crankcase ventilation is a system in internal combustion engines that allows for the removal of gases that accumulate in the crankcase during operation. These gases, primarily consisting of blow-by gases from the combustion process, can contain harmful pollutants and moisture. The ventilation system typically uses a PCV (Positive Crankcase Ventilation) valve to redirect these gases back into the intake manifold for re-combustion, which helps reduce emissions and maintain engine efficiency. Proper crankcase ventilation is essential for engine longevity and performance.

The aortic valve, often referred to as the AIC valve, is located between the left ventricle of the heart and the aorta.
