  • Rotary internal combustion engine for combusting low cetane fuels
    Patent number: 8056529
    Abstract: This invention presents a compact, light, efficient and high power output rotary internal combustion engine utilizing the waste heat. The engine has a rotor rotatable within a housing, but has no piston. The rotor has a plurality of combustion chambers, with inlets for introduction of fuel and outlets for exhaust of combustion products. The exhaust imparts rotation to the rotor within the housing. Fixed end caps are provided at each end of the housing. The engine is cooled with steam, air and water. The engine is suitable for applications that require efficient, high power to weight ratio, such as aircrafts, ships, and heavy duty transportation. The engine may use low grade fuel with a low cetane number, by using specially treated pulverized coal.
