Patent DE-19600853-A1 (DE)
Inventor: STRAUS ANDREAS DIPL ING
IPC: F01L1/344
Filed: 1996-01-12
Abstract: In a device (1) for changing the timing of an internal combustion engine, a hydraulic leakage gap damper (35) is fitted in its pressure chambers (13, 15).

Patent DE-19601593-A1 (DE)
Inventor: MAYER ULRICH DIPL PHYS DR
IPC: F02P5/00
Filed: 1996-01-18
Abstract: The invention concerns a method of controlling ignition in a multicylinder internal combustion engine, the control variables being determined with reference to the parameters detected by sensors and misfiring being monitored as a function of the output of the control variables. When an ignition signal is emitted, the torque at the combustion step triggered by the ignition is detected and compared with a mean value of the torques of preceding combustion steps. If, in this respect, a deviation in the torque detected at a given moment from the mean value of the torques of preceding combustion steps is greater than a predetermined threshold, the misfiring detection system is switched off.
