Abstract

A sensing means is provided to monitor combustion of fuel and air supplied to an internal combustion engine, for example by sensing ignition pulses, combustion pressure, or cylinder temperature. Signals, as sensed, are evaluated and if one of these signals is beyond a certain threshold (e.g. extreme with respect to a set value, or with respect to an average of all signals) as sensed by threshold switches, supply of the combustible fuel-air mixture to the specific cylinder is interrupted.
