Control device for electrical system and electric solenoid fuel injection and ignition systems of petrol engine of car, has power triode and cooperation resistor for charging pulse signal in terminal of electric current supply on vehicle

摘要

The device has a temporization circuit constituted of resistors (51, 52) and a capacitor (53), for controlling a pulse generator (60) that is in the form of an integrated circuit so that the generator generates a rectangular transitory pulse signal. The signal is limited by a resistor (61) and phase shifted and amplified by a triode (62) and a cooperating resistor (10), respectively, and allows a switching operation. A power triode (16) and a cooperating resistor (14) charge the signal in a positive terminal of an electric current supply on a vehicle i.e. car, having a petrol engine.
