Abstract
The invention relates to a method for improving the thorough mixing of the exhaust gas/fuel mixture in an internal combustion engine (,), whereby the exhaust gas stream is at least temporarily impinged upon by an increased exhaust-gas mass flow when additional fuel is supplied. According to said method, during the exhaust stroke, when the exhaust valve (,) or exhaust valves are open, the additional fuel is fed directly into the combustion chamber of the internal combustion engine (,). The invention also provides for a device to carry out said method, according to which the additional fuel is injected during the exhaust stroke when the exhaust valve (,) or exhaust valves (,) are open by means of at least one injection nozzle (,) positioned in the combustion chamber. Both the method and the device are especially simple and cost-efficient.
