Computerized Engine Controls

ENGINE CONTROL SYSTEM

Engine control system is a computerized emission, ignition and fuel injection control system. Engine control system lowers exhaust emissions while maintaining good fuel economy and driveability. Engine control system consists of various sensors, switches and control units. See Fig. 9 -Fig. 28 . The Engine Control Module (ECM) controls engine control system based on input signals received from various input devices. ECM contains preprogrammed data to maintain optimum engine performance under all operating conditions.
