Abstract:
An internal combustion engine, comprising,:a first cylinder formed in a block of said engine;a first piston connected to a crank shaft of said engine by a first connecting rod and disposed for reciprocal movement within said first cylinder between a first combustion chamber of said first cylinder and a first crankcase chamber of said engine, a pressure within said first crankcase chamber changing in magnitude in response to said reciprocal movement of said first piston;a compressor having an air inlet and an air outlet, said air outlet being connected in fluid communication with said combustion chamber to provide pressurized air into said combustion chamber;a first conduit connected in fluid communication between said air inlet and said first crankcase chamber to provide air to said air inlet of said compressor as said piston moves toward said first crankcase chamber;a second cylinder formed in a block of said engine;a second piston connected to a crank shaft of said engine by a second connecting rod and disposed for reciprocal movement within said second cylinder between a second combustion chamber of said second cylinder and a second crankcase chamber of said engine, a pressure within said second crankcase chamber changing in magnitude in response to said reciprocal movement of said second piston; anda plenum chamber connected in fluid communication between said air outlet of said compressor and said first and second combustion chambers; anda manifold chamber connected in fluid communication with said first and second crankcase chambers, said manifold chamber being connected in fluid communication with said air inlet of said compressor to provide air to said air inlet of said compressor.
