IGNITION APPARATUS FOR INTERNAL COMBUSTION ENGINES

摘要

An ignition apparatus for an internal combustion engine having two or more cylinders. Two or more sensors are correspondingly associated with the two or more cylinders. These sensors are further correspondingly associated with flip-flops. The outputs of these flip-flops are combined by an OR gate and then distributed by an additional distributing flip-flop and AND gates for each of ignition elements also associated with the cylinders, whereby even though the output of any one of the sensors fails to attain a required level of the flip-flops, an erroneous distribution is prevented for the ignition elements of the engine.
