Abstract
A device for introducing fuel into the combustion chamber of an internal combustion engine, includes a unit for fuel delivery and an injection valve for withdrawing compressed gas from the cylinder and injecting the gas together with the delivered fuel into the cylinder, and a mixing space in the front part of the valve for the purpose of gas storage, the injection valve being provided with a valve for control of the gas exchange between the combustion chamber and the mixing space in the front part of the valve. To obtain reproducible operating conditions and an optimum closing time (E.sub.0) for the injection valve, the mixing space is connected to one or more sensor elements for measuring the pressure and/or temperature of the mixing space, and that the valve is closed in dependence on the physical quantity measured by the at least one sensor element.
