ABSTRACT:
Present reciprocating engines have limitations on their thermal efficiency and horsepower to weight performance imposed by the crankshaft. Elimination of the crankshaft, use of a full time turbocharger and ceramic lining of cylinder walls, cylinder and piston heads and exhaust conduits permit the construction of an engine which has a thermal efficiency and horsepower to weight performance exceeding that of present engines. Use of ceramic linings is not essential to the operation of the engine. Thermal efficiency without ceramic linings is still better than that of crankshaft engines. Power produced by said crankless engine is oscillatory however this is readily rectified into rotary power.
