Reciprocating internal combustion engine (1) having a cylinder (3), a crank mechanism (2), a piston (4) which is movably mounted in the cylinder (3) acting on the crank mechanism (2) and the one through it and the cylinder (3) formed chamber (6) gas-tight, an inlet valve (5a, 5b), which regulates a supply of fresh gas to the chamber (6), an outlet valve (7) which controls a gas discharge from the chamber (6), a control unit which controls the opening and closing of the at least one inlet valve (5a, 5b) and the at least one outlet valve (7), and an ignition unit for igniting the fresh gas. The piston (4) carries out a working stroke in a movement expanding the chamber (6) and an ejection stroke in a movement compressing the chamber (6), the inlet valve (5a, 5b) being at least partially opened during the working stroke, and wherein Exhaust valve (7) is at least partially open during the exhaust stroke. |
