BEOBACHTUNG DER VERBRENNUNG IN EINER GEZUENDETEN BRENNKRAFTMASCHINE.

摘要

The ignition voltage is monitored to determine whether combustion in the engine combustion chamber has taken place. The duration of the discharge voltage is monitored. The voltage at the primary side of the ignition coil is monitored. A computer (13) monitors the duration of the discharge voltage and in particular checks the duration of the discharge voltage following a falling flank (11 or 12). The computer (13) is connected to the primary side of the ignition coil (15) of the ignition system. A low-pass filter (17) is connected to the primary winding of the ignition coil (15).
