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.

A reactor protective system to protect a catalytic reactor connected to a multicylinder internal combustion engine system against damage or destruction due to excessive temperatures arising in the reactor, said reactor protective system comprising engine operation sensing means (32-35) located in sensing relation to each of the cylinders (12-15) of the engine (10), sensing a characteristic of a combustion event in the respective cylinder to monitor combustion of fuel and air supplied thereto, and providing a respective combustion monitor signal representative of conditions, indicative of presence, or absence of combustion in a respective cylinder; supply control means (37-40; 68-71) controlling supply of combustible mixture of air and fuel to respective cylinders; and separate threshold switches (56, 61, 65) associated with and connected to each sensing means (32-35) associated with respective cylinders of the engine, the threshold switches providing a threshold level forming a reference or command level for the combustion monitor signal of each of the cylinders and changing state if the monitor signal from the sensing means passes the threshold level of the threshold switch means, said threshold level being matched to the operating temperature of the catalytic reactor under normal conditions, said threshold switches being further connected to said supply control means to inhibit supply of combustible mixture to the respective cylinder from which a monitor signal is derived which causes the threshold switch to change state to thereby inhibit escape of unburnt fuel-air mixture from the engine into the reactor and combustion of said unburned mixture therein and thus prevent consequent damage to the reactor; and a condition signal generating circuit (148, 149, 150, J, L; 112, 113, 114, J′, L′; 51, 54) generating a signal representative of, and controlling the threshold level at which the separate threshold switches (56, 61, 65) change state; wherein the condition signal generating circuit comprises a coupling circuit (148, 149, 150; 112, 113, 114) having an output junction (J, J′); a transistor (51) in emitter-follower circuit connected to said output junction (J, J′) and a Zener diode (54) coupling the transistor (51) and said separate threshold switches to apply the signal controlling the threshold level of said switches to said switches.
