Control System

MFI Control System (DOHC with M/T)

Circuit Description
The Multiport Fuel Injection (MFI) control system is an electronic fuel metering system with fuel injectors near the inlet port of each cylinder. The amount of fuel injection is determined by the ECM according to engine speed and intake air-flow quantity measured. The emission control system includes the oxygen sensors and catalytic converters. The MFI's three major functions are air-fuel mixture, idle speed, and ignition timing control.

Circuit Description
The Multiport Fuel Injection (MFI) control system is an electronic fuel metering system with fuel injectors near the inlet port of each cylinder. The amount of fuel injection is determined by the PCM according to engine speed and intake air-flow quantity measured. The emission control system includes the oxygen sensors and catalytic converters. The MFI's three major functions are air-fuel mixture, idle speed, and ignition timing control.
