Title:
SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE FOR COMBUSTION CONTROL
Document Type and Number:
Japanese Patent JPH04244508
Kind Code:
A
Abstract:
PURPOSE: To strengthen a device against noise upon ignition and reduce a circuit current compared with prior art upon combustion after the firing.
CONSTITUTION: During operation of an igniter 8, a switching element 18 is turned on, and currents from current supplies 19, 20 are all driven to flow to an injector, and after the ignition, the switching element 18 is turned off to allow an injector current to flow only from the current source 19. Thereby noise resistances upon ignition and during combustion and power consumption are improved.
