Title: Contactless spark ignition system of internal combustion engine
Inventor: KOMIYA KOUKICHI
IPC: F02P5/155
Filed: 1981-04-09
Abstract: PURPOSE:To enable a spark ignition system of inductive electrical discharge type to effectively operate over the whole speed range of an engine by providing a second condenser which greatly delays the timing of ignition during low speed running including engine start but advances it during high speed running. CONSTITUTION:Since the reverse voltage charged in a first condenser C1 is low during low speed running, the turning-on time of a transistor Tr counted after primary short-circuit current has started to flow by turning-on a transistor circuit TrC, is greatly delayed. Because of the provision of a second condenser C2 disposed between the gate of a thyristor SCR and the transistor circuit TrC, collector voltage which rises before the turning-on of the transistor Tr and is applied to the thyristor SCR, is absorbed by the second condenser C2 so that unnecessary spark advance may be avoided. During high speed running, electrical current circulating through a primary winding T1 exhibits an evident A.C. current-like characteristic so that the impedance value of the second condenser C2  becomes low, thereby the ignition timing is advanced.
