ABSTRACT:
Two embodiments of crankcase compression, internal combustion engines have air/fuel injection systems that include an air compressor driven by the engine and protected by the intake manifold. In one embodiment, the air compressor also drives a water pump and in both embodiments the induction system is designed so as to maintain substantially equal length runners for the individual crankcase chambers. This is accomplished by forming the check valves the communicate the runners with the crankcase chambers in parallel relationship to the respective runners.
