An engine having a working chamber and a combustion chamber and a method for operating it are disclosed. The amount and compression ratio of air entering the combustion chamber are controlled by valves at the working chamber. The maximum possible amount of air is inducted into the working chamber, and then air is discharged until an amount necessary for the existing load on the engine remains. This remaining air is then compressed to a predetermined constant compression ratio at which it enters the combustion chamber. A proportional amount of fuel is supplied, and the resulting combustion gas is then transferred to do work in the working chamber. The amount of combustion gas transferred is sufficient to maintain a substantially constant pressure in the combustion chamber.

A method for operating a combustion engine comprising the steps of: inducting into a working chamber an amount of air corresponding to the amount required at full-load operation of the engine; discharging from the working chamber a first part of the inducted air for retaining a second part of the inducted air in the working chamber, the second part being equal to the amount required for operation at the actual engine load; compressing the second part of the inducted air until the compression ratio of the second part reaches a predetermined compression ratio that is constant for varying loads; transferring the compressed air into a combustion chamber, mixing fuel with the compressed air and combusting the mixture of fuel and air in the combustion chamber to produce combustion gas; transferring the combustion gas into the working chamber and performing work therein with the combustion gas; and discharging the combustion gas from the working chamber.
