General System Description

Fig. 61 Fuel Injection Control:

In the Electronic Concentrated engine Control System (E.C.C.S.), the control unit employs a micro-computer. This micro-computer controls fuel injection, spark timing, idle speed, fuel pump operation, and mixture ratio feedback Fig. 61.
Electronic signals from each sensor are fed into the micro-computer and each actuator is controlled by an electrical pulse with a duration that is computed in the micro-computer.
