Title:
START CONTROL CIRCUIT OF CONTACTLESS IGNITION DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP3413508
Kind Code:
B2
Abstract:
PURPOSE: To provide the start control circuit of a contactless ignition device adapting the action for the operation of an internal combustion engine caused by the on and off of a relay switch to the operation state as the technical problem, securing the smooth and stable operation, securing the safety at the time of a start, having a simple structure, easy to manufacture, and requiring no adjustment.
CONSTITUTION: This start control circuit of a contactless ignition device is provided with the first switching element 3 disabling the operation of an ignition circuit via the backward voltage of the primary winding of an ignition coil when a relay switch 8 is set to the on-state and the second switching element 5 disabling the triggering of the first switching element 3 via the forward voltage of the primary winding. Since the triggering of the first switching element 3 is disabled by the forward voltage normally generated when the ignition circuit is operated, no adjustment of operation is required, and the circuit structure becomes very simple.
