Patent ID: 7011071

Claim:
An internal boost system integrated to an engine, the internal boost system comprising: a blanking plate adapted to be positioned between a lower-end of the engine and an oil sump; a plenum chamber disposed within the oil sump having an exit flange disposed through a side of the oil sump; at least one one-way valve disposed through the blanking plate adapted to allow compressed air flow into the plenum chamber; a plurality of one-way valves disposed through the lower-end of the engine to allow fresh air to be drawn internally into the engine; a fresh air manifold in communication with the plurality of one-way valves disposed through the lower-end of the engine; and an internal boost supply pipe in communication with the plenum chamber exit flange and an air intake manifold of the engine; wherein backsides of pistons, lower main journal walls from the lower-end of the engine, and a topside of the blanking plate form an internal compression chamber within the lower-end of the engine for each respective piston; wherein fresh air is drawn into a respective internal compression chamber for each respective piston when each piston is moved upward and compressed by the backside of the piston when the piston is pushed downward; and wherein the compressed air flows through a respective one of the plurality of one-way valves into the plenum chamber, flows through the internal boost supply pipe, and then flows into the air intake manifold to provide a boost in pressure within compression chambers of the engine.
