发明名称 METHOD AND ARRANGEMENT FOR RECOGNIZING MISFIRES
摘要 PCT No. PCT/DE89/00628 Sec. 371 Date Apr. 15, 1991 Sec. 102(e) Date Apr. 15, 1991 PCT Filed Oct. 4, 1989 PCT Pub. No. WO90/04093 PCT Pub. Date Apr. 19, 1990.An arrangement for recognizing misfires in an internal combustion engine has a sensor (15) for measuring the exhaust-gas pressure and a means (16, 17, 18) for recording the measurement values of the sensor for each clock pulse. Each exhaust-gas pressure measurement value is compared to a corresponding expected value and an occurrence signal is emitted when the two values differ from one another by more than a specified difference. A means (21) for recognizing and treating faults determines the rate of occurrence of the occurrence signals and emits a fault signal when the rate of occurrence determined exceeds a threshold value. A warning lamp lights up on receipt of the fault signal. This arrangement for recognizing misfires has a simple construction because the ignition in all the cylinders of an internal combustion engine (11) can be simultaneously monitored by means of a single sensor. In addition, it is possible to determine faults in the exhaust-gas line (12) as well as misfires.
