Abstract
The present invention relates to a design and method of operation of an improved rotary piston engine. In particular, a preferred embodiment of the present invention is directed to a rotary engine with improved reliability, comprising a housing, having side portions and a peripheral portion defining a chamber, a rotor, disposed within the chamber, and at least one exhaust port in one of the side portions.
Claims32
A rotary engine with improved reliability, comprising:
- a housing, having side portions and a peripheral portion defining a chamber;
- a rotor, disposed within said chamber;
- and
- at least one exhaust port in one of said side portions.
A rotary engine, comprising:
- a housing, having an inner surface, and intake and exhaust means;
- a crankshaft;
- and
- a rotor, rotatable within said housing and around said crankshaft, said rotor having at least one seal provided at the apex of said rotor, wherein said at least one seal maintains continuous sliding contact with said inner surface of said housing, and wherein said at least one seal does not contact said intake and exhaust means.
A rotary engine, comprising:
- a housing, comprising intake and exhaust ports, fuel delivery means, and ignition means;
- a crankshaft disposed within said housing;
- a rotor, rotatable within said housing and around said crankshaft, forming a chamber between said housing and said rotor;
- and
- an engine controller for monitoring the condition of the engine and controlling said fuel delivery means and said ignition means.
An engine having one or more combustion chambers, intake and exhaust means, and combustion chamber means comprising:
- a fuel injector, for direct fuel injection;
- and
- means for modifying the timing of said fuel injection as a function of crankshaft speed between a first point corresponding to opening of intake means and a second point corresponding to combustion chamber means being in proximity to said fuel injector,
- wherein, the operation of said engine is optimized.
A method of managing the fuel injection of a rotary engine comprising:
- setting injector timing at a starting point;
- modifying the injector timing as a function of the speed of the engine;
- maintaining the injector pulse between a first point at which the intake port opens and a second point at which the trailing edge of the piston approaches proximity to the injector;
- to increase performance of the engine at air/fuel ratios at or about in excess of 15:1.
