ABSTRACT:
A method for use in generating power in an internal combustion engine from combustion of a fuel admixed with an oxidizing gas and operating cyclically with intentional ignition of a first fuel or with self-ignition of a second fuel which includes changing a volume of a combustion chamber from a fixed minimum volume to a fixed maximum volume wherein the maximum volume is greater than a critical volume. The critical volume includes a volume of the chamber filled with an oxidizing gas at an initial temperature and an initial pressure such that when the temperature is compressed from the critical volume to the minimum volume the gas reaches a maximum temperature and a maximum pressure causing detonation of a first fuel, or the gas exceeds a maximum temperature and a maximum pressure predetermined for self-ignition of a second fuel. A flow of the gas is controlled into the chamber so as to provide an upper limit on the amount of the gas which fills the chamber in each chamber-filling intake part of an engine cycle. The upper limit includes a mass less than an amount of a mass of the oxidizing mass in the critical volume.
