    摘要: For the checking of an exhaust gas recycling valve, the control signal for the exhaust gas return valve is returned from a defined value to zero, in the idle state of the internal combustion engine while the vehicle is at a standstill and the reaction of the signal (MAF) from an airflow detector in the inlet tract is evaluated. Should the signal not exceed a given threshold value (MAE SWD), within a first time period (T2), then a faulty dynamic is assigned to the exhaust recycling valve. Should the signal not exceed a second given threshold value (MAF SWS), within a second time period (T3), then it is determined that the exhaust recycling valve can not be completely shut.

    摘要: A method for controlling an injection of fuel in an internal combustion engine in which steady-state optimum injection parameters, in particular the start-of-injection angle, is corrected for non-steady-state operating phases. The correction is carried out by a transmission element to which the driver's request is fed as an input and correction parameters are determined therefrom. Using the correction parameters, fuel injection parameters obtained from a characteristic diagram that is optimum for steady-state operating conditions are corrected. In this manner, the behavior of the internal combustion engine is improved for non-steady-state operating phases.
