Abstract:
1. A method of controlling power output of an internal combustion rotary engine having: (i) a housing having an intake port for receiving air for provision to a combustion chamber and an exhaust port for discharging exhaust gas, (ii) a rotor mounted to the housing and configured for rotational motion relative to the housing, wherein the combustion chamber is formed by the rotor and the housing during a combustion phase of a cycle of the engine, (iii) a fuel injector mounted and configured to inject fuel into the combustion chamber, wherein gases formed by combustion of the injected fuel expand to produce motion of the rotor in the rotary engine during an expansion phase, and (iv) a controller coupled to the fuel injector to control operation of the fuel injector in a duty cycle comprising a plurality of on-cycles and a plurality of off-cycles, the method comprising: receiving an engine signal at the controller; in response to the engine signal, continuing to allow air to be delivered into the combustion chamber during each off-cycle of the rotary engine, so that the allowed air causes heat transfer from walls of the rotary engine so as to cool the rotary engine.
