  • Arrangement for recognizing misfirings in internal combustion engines with externally controlled ignition
    Patent number: 4986232
    Abstract: An arrangement for the recognition of misfirings of internal combustion engines with externally supplied ignition in which for the recognition of misfirings, the cylinders are combined into two groups and an ignition system of its own is coordinated to each group; a thermo-element is thereby arranged in the exhaust tract of a cylinder of each group. A pair of thermo-elements is series-connected in opposite polarity and the resulting thermo-voltage at the free ends is monitored by means of two threshold circuits. From the amount and sign of the resulting thermo-voltage, a defective ignition system can be determined and the corresponding cylinder group can be turned off.
