Blow-by gas heating system for internal combustion engines
Abstract
This patent describes a blow-by gas heating system for a water-cooled internal combustion engine having an engine block, an intake manifold, a crankcase, and an overhead valve cover, and an air inlet port on the valve cover and a crankcase blow-by gas outlet port on the crankcase, with those ports at spaced locations, comprising, conduit means separate from the engine block connecting the blow-by gas outlet port to the intake manifold and including valve means for controlling the blow-by gas flow therethrough, conduit means separate from the engine block connecting the air inlet port to a source of fresh air, coolant conducting means separate from the engine block connected to the engine water-cooling system for circulating engine heated coolant through the coolant conducting means, the coolant conducting means positioned in heat exchange relationship with at least a portion of one of the conduit means for heating the portion of the conduit means and the gas flowing therethrough, and the coolant conducting means including a coolant jacket portion in heat exchange relationship with the valve means for heating the valve and blow-by gas flowing therethrough.
