Abstract: A fuel injecting method and a corresponding arrangement for an internal combustion (10), especially of a motor vehicle, wherein a first injection takes place during an induction stroke. Proceeding from operating characteristic variables of the engine (10), a tendency-to-knock signal is determined which characterizes the tendency to knock of the engine (10). At least one second injection takes place when the tendency-to-knock signal exceeds a threshold value. (FIG.

Abstract: An on-board diagnostic arrangement is disclosed for checking component systems of a motor vehicle by test functions which are triggered during operation of the motor vehicle under predetermined start conditions. The test functions are characterized in that at least one signal can be coupled into the arrangement via which the triggering of the test functions by the arrangement is inhibited and in that at least one test function, which is carried out by the arrangement, is triggered independently of the predetermined start conditions and/or can be modified in its sequence. The arrangement makes possible a shortening of the check of component systems at the end of an assembly line or after customer service because satisfying time-consuming start conditions for the normal operation of the test functions can be omitted.

Abstract: An arrangement enabling a reliable detection of speed-of-rotation deviations between two exhaust-gas turbochargers of an internal combustion having separate cylinder banks included a device, which determines the difference between the pressures prevailing in the two exhaust trains of the two cylinder banks upstream from the exhaust turbines and signals a relevant speed deviation when the pressure difference determined exceeds a specifiable threshold.

Abstract: The torque of an internal combustion engine is controlled during acceleration by monitoring differences between engine and wheel speed in order to provide a measure of phase differences in the event of the engine torque oscillating. The difference between the engine and wheel signals is integrated and fed to an ignition angle correction circuit in order to damp out the torque oscillations which would otherwise result.
