摘要： The invention relates to a method and an apparatus for determining an exhaust gas recirculation rate in an internal combustion engine, in which the exhaust gas recirculation rate indicates a proportion of exhaust gas in a gas quantity delivered to a cylinder of the internal combustion engine, and combustion takes place in the cylinder of the engine cyclically during a combustion phase. The method includes the steps of ascertaining a combustion course statement over the course of combustion in the cylinder of the engine, and ascertaining an actual exhaust gas recirculation rate from the combustion course statement with the aid of a predetermined exhaust gas recirculation rate function. The invention further relates to a method and an apparatus for regulating an exhaust gas recirculation rate in an internal combustion engine, in which the exhaust gas recirculation rate indicates a proportion of exhaust gas in a gas quantity delivered to a cylinder of the internal combustion engine, and combustion takes place in the cylinder of the engine cyclically during a combustion phase. The method includes the steps of ascertaining a combustion course statement over the course of combustion in the cylinder of the engine, furnishing a set-point statement as a function of an operating point of the engine, and performing a regulation to compensate for a deviation that results from the set-point statement and the combustion course statement.

摘要： The aim of the invention is to optimize the running smoothness of an internal combustion engine. To achieve this aim, the individual cylinders are synchronized with respect to their torque contribution. According to the method, fuel is injected into the combustion chamber of a cylinder in at least one injection step, the at least one injection contributing to the torque of the internal combustion engine. Fuel is injected into the combustion chamber of the cylinder in a torque neutral manner by way of a secondary injection during a working stroke of the cylinder and the amount of fuel of the secondary injection us calculated in such a manner that the exhaust gas substantially corresponds to a stoichiometric air/fuel mixture.
