ABSTRACT:
A combustion detect device for use in an internal combustion engine including an ignition coil in which a high voltage for ignition is generated at a secondary winding when the current of a primary winding is cut off, and an ignition plug for discharging and igniting a mixture gas when said high voltage for ignition is applied thereto, the combustion detect device comprises an ion current detection device for detecting an ion current generated due to combustion of a mixture gas by applying a voltage to an ignition plug and a restriction device for restricting a voltage generated in the secondary winding when a primary winding is turned on to conduct.
