IGNITER FOR AN ENGINE

摘要

An igniter for an internal combustion engine is provided which is small in size, efficient and inexpensive to manufacture. The entire manufacturing process can be easily automated. The igniter includes a power transistor circuit for turning on and off the current supply to a primary winding of an ignition coil, a current detector for detecting a current supplied to the ignition coil primary winding, and a current limiter for controlling the current supplied to the ignition coil primary winding based on the current detected by the current detector. The current detector comprises a conductor in the form of a conductive wire separately formed from the current limiter and connected between ground and a junction between the power transistor circuit and the current limiter.
