Abstract
Fumes disposal systems used with existing engines are complex, induce pollution and cause engine malfunction to occur. The present fumes disposal system overcomes these problems by utilizing the heat from the engine exhaust to heat a tubular member and cause excessive oil droplets, carbon particles and fumes to burn. The flow of exhaust from the engine is used to dissipate the remaining crankcase fumes insuring that any concentration of fumes are purged with the exhaust. Furthermore, the system controls the pressure within the crankcase of the engine.
