Automotive Blow by Heaters Market: Introduction Automotive Blow by Heaters are also known as crankcase ventilation valve heaters which prevent ice formation when treating the combusted, hot gas venting from the crankcase. The gas generated during compression in a combustion engine or piston compressor is known as “blow-by”. During combustion, hot gas contaminated with hazardous substances enters the crank case. This gas is then de-oiled, evacuated and reintroduced for combustion in the induction tract. Ice formation occurs due to the difference between the temperature of the warm blow-by gas and that of the cold intake air. The water content in the warm blow-by gas may condense and freeze upon contact with the cold intake air. Moreover, when the ECU of the vehicle detects the risk of ice formation, it switched on the automotive blow-by heaters through an external relay/power switch. Automotive Blow by Heaters warms the re-circulated crankcase gases, which avoid the ri...
