【発明の名称】内燃機関用点火装置
Document Type and Number:
Japanese Patent JP2569195
Kind Code:
B2
Abstract:
An ignition system for internal combustion engines comprising an ignition coil (38), a power circuit (30) including a converter for converting the output of a battery (31) into a high voltage, a capacitor (37) arranged at the primary side of the ignition coil (38) and charged by the output from the power circuit (30), a discharging control thyristor (41) which conducts at a spark-timing of an internal combustion engine to discharge electric charges in the capacit of (37) into the primary winding (38a) of the ignition coil (38) and converter control means (49, 52) which makes the converter inactive earlier than the input of a trigger signal to the gate of the thyristor (41) by a first predetermined time (t1), and which makes the converter active again in a second predetermined time (t2) since the thyristor (41) has been triggered to conduct.
