ABSTRACT:
This invention relates to a method for preventing premature ignition in an ignition device for the internal combustion engine including a non-contact type ignition circuit for the internal combustion engine, particularly an ignition circuit for the internal combustion engine in which an inductive current in the form of an AC waveform induced in a primary winding of an ignition coil is controlled in its conduction and cut-off by means of a transistor circuit, various auxiliary circuits to be disposed for a desired performance in accordance with the purpose of use and the rate of this circuit, and an ignition circuit for the internal combustion engine in accordance with the present invention, and more particularly to a method for preventing premature ignition in an ignition device for the internal combustion engine comprising a transistor circuit for controlling in conduction and cut-off of a primary short-circuit current in the whole circuit and a trigger circuit for controlling the trigger in said transistor circuit, in which auxiliary circuits are added to said trigger circuit or said transistor circuit in accordance with the purpose of use and requirements of the circuit to attain a desired performance, and disadvantages inherent in the inductive discharge type ignition circuit for the internal combustion engine in the art of the present invention are eliminated.
