Title:
IGNITION DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPS5623568
Kind Code:
A
Abstract:

PURPOSE: To improve the ignition of an internal combustion engine, reduce the heat loss of an ignition coil and prevent a switch from burning, by connecting an inductive discharge type ignition circuit and a capacitive discharge type ignition ciricuit to a spark plug.

CONSTITUTION: An inductive discharge type ignition circuit 10 as the first ignition ciricuit and a capacitive discharge type ignition circuit 40 as the second ignition circuit are connected to a spark plug 1. The first ignition circuit 10 acts to turn on and off the current of a primary coil 14a by opening and closing a contact 13 to cause a high-voltage current to flow through the secondary coil 14b. The second ignition circuit 40 acts to transmit electric charge stored in a capacitor 42 coupled to a primary coil 41a, to the primary coil to produce a high voltage across the secondary coil 41b.
