IGNITION COIL ELECTRIC CURRENT CONTROL SYSTEM OF AN ENGINE, WHICH PREVENTS THE EXCESSIVE CURRENT ON IGNITION COIL THROUGH CURRENT CAPACITY LIMIT UNIT

摘要

PURPOSE: An ignition coil electric current control system of an engine is provided to stably minimize errors on a target timing advance.;CONSTITUTION: An ignition coil electric current control system of an engine comprises a main switching(10), a current capacity limit unit(20), and a controller(40). The main switching supplies current to an ignition coil(30) from a battery according to an external control signal. The current capacity limit unit is located between the ignition coil and the main switching. The current capacity limit unit reduces the current amount offered to the ignition coil according to the external control signal.;COPYRIGHT KIPO 2012
