Abstract
A rotary engine has a rotor with a rotor pocket for receiving air-fuel mixture that is combusted therein to propel the rotor within the housing. The rotary engine may have one or more intake spray injectors that spray fuel into the rotor pocket and onto the rotor face within the intake chamber to effectively cool the rotor pocket and rotor face. An air channel extension of the rotor pocket may be configured in the housing and/or in the rotor to extend from the compression chamber into the ignition-combustion chamber to relieve some pressure in the trailing compression chamber of a rotor face to minimize negative work. A supplemental air-fuel conduit may be configured to supply high-pressure gas from the compression chamber to an ignition injector(s). A thrust nozzle may be configured within the rotor pocket to direct combustion gases therethrough to propel the rotor and increase efficiency.
