    摘要: A method for operating an internal combustion engine, in particular of a motor vehicle, in which fuel is injected either in a first operating mode during a compression phase, or in a second operating mode during an intake phase, directly into a combustion chamber. In both operating modes, the fuel mass injected into the combustion chamber is controlled and/or regulated as a function, among other things, of a calculated reference torque to be delivered by the internal combustion engine. A true torque delivered by the internal combustion engine and a permissible torque are determined; and the true torque is compared to the permissible torque.

    摘要: The invention is directed to a method for determining causes of faults in the formation of the air/fuel mixture for an internal combustion engine. First, different operating parameters of the engine are detected and at least three load signals are formed on the basis of at least somewhat different operating parameters. The three load signals represent respective air quantities which flow into the engine. Different pairs of two load signals in each pair are formed and deviations of the each two load signals of a pair with respect to each other are determined for different pairs. Different causes are allocated to different combinations of pairs wherein deviations were determined.

    摘要: A method for operating an internal combustion engine (100), particularly of a motor vehicle, operated with a gas as fuel, a lambda value of an air/fuel mixture being regulated by means of lambda control as a function of a signal from a lambda probe (130), and, when a lean/rich jump is detected by the lambda probe (130), a mixture control factor (GRF) which controls the mixture composition being varied at least for a predeterminable time such that a shift of the lambda air ratio toward rich is caused, is characterized in that the mixture control factor (GRF) is varied in such a way that an additional defined shift of the lambda air ratio toward rich is caused.
