Abstract
A four-stroke combustion engine, preferably a turbocharged diesel engine, incorporates a combustion chamber, one or more inlet valves (4), and at least one camshaft (5) controlling the valves so as to open the inlet valves during the engine inlet stroke in order to feed combustion air from an inlet line (6, 7) into the combustion chamber. For feedback of part of the exhaust gases, at least one of the inlet valves (4) is arranged to be also able to be opened during part of the engine expansion stroke and/or exhaust stroke, so that part of the exhaust gases is fed back to the inlet line (6, 7) in order to be fed into the combustion chamber together with new combustion air during a subsequent inlet stroke.
