Abstract
The invention relates to a method of operating an internal combustion engine and to an internal combustion engine respectively. In accordance with the method of operating an internal combustion engine in accordance with the invention fuel is injected into a combustion chamber so that it is reflected by a piston, as a result of which charge stratification occurs in the combustion chamber. Fresh air is inducted slightly throttled or not throttled at all into the combustion chamber irrespective of the loading condition of the internal combustion engine so that the exhaust gases from the previous working stroke are completely swept from the combustion chamber. The output of the internal combustion engine is generated substantially via the injected amount of fuel.Dueto the method in accordance with the invention charge stratification is caused in which burning of the fuel/air mixture is ideal. The internal combustion engine in accordance with the invention thus features smooth running for ideal emission values.
