    摘要: An internal combustion engine for a motor vehicle. In the internal combustion engine, fuel is injected directly into a combustion chamber and is burned during an intake phase in a first mode of operation and during a compression phase in a second mode of operation. Exhaust gas formed by combustion may be sent to a catalytic converter. A controller may cause additional fuel to be injected following combustion in the second mode of operation. The controller may also cause the temperature of the exhaust gas to be measured in or downstream from the catalytic converter and compared with a threshold value.

    摘要: An internal combustion engine, in particular for a motor vehicle, in which fuel may be injected into a combustion chamber during an intake phase in a first mode of operation or during a compression phase in a second mode of operation, and in which exhaust gases may be sent to a catalytic converter. A control unit determines a temperature difference between an actual exhaust gas temperature and a setpoint exhaust gas temperature at an operating point having a low exhaust gas temperature. In addition, at least one additional injection after combustion is implemented by the control unit as a function of the temperature difference.

    摘要: A fault diagnostic device for monitoring and detecting faults in technical functions, in particular in technical functions of a motor vehicle, includes a plurality of monitoring devices for monitoring technical functions, whether they have a fault or not. The fault diagnostic device also includes a storage device for storing (data concerning) direct mutual dependencies of the functions to be monitored, in the form of a matrix representation in the logical YES/NO form. Furthermore, the fault diagnostic device includes a processing device for determining the capacity for validation of faults in corresponding technical functions to be detected in the monitoring, in view of the matrix representation; for controlling the monitoring devices for carrying out the monitoring activities; and, assuming the capacity for validation, for validating the faults to be detected in the monitoring.
