ABSTRACT:
A superchargeable multi-cylinder 2-stroke cycle internal combustion engine employs opposite reciprocating mult-port slide valves in guideways on opposite sides of the engine block, to open and close cylinder air supply and combustion gas discharge conduits in several variations. Use of opposite multi-port slide valves driven from the engine crankshaft simplifies engine design, and improves scavenging of combustion gases from piston chambers of either spark-ignition or diesel engines. A preferred variation channels air supply and combustion gas discharge flows through dual passageways of opposite air preheating manifolds, to increase engine fuel efficiency, Further development of the preferred variation can result in production of simplified, compact, supercharged 2-stroke spark-ignition and diesel engines of improved design.
