1. General:
! The Multipoint Fuel Injection (MFI) system supplies optimum air-fuel mixture under every engine
operating condition through the use of the latest electronic control technology.
This system pressurizes the fuel to a constant pressure and injects it into each intake air port in
the cylinder head. The injection quantity of fuel is controlled by an intermittent injection system
where an electro-magnetic injection valve or injector opens for a short period that is precisely controlled
depending on the quantity of air appropriate for each condition of operation. In actual control,
an optimum fuel injection quantity is achieved by varying the duration of an electric pulse
applied to the injector. This way of control enables simple, yet highly precise metering of the fuel.
! The engine control module (ECM) that controls the fuel injection system corrects the fuel injection
amount depending on the vehicle speed, throttle opening, coolant temperature and other vehicle-
operation-related information. The ECM receives the information in the form of electric
signals from the corresponding sensors and switches.
The MFI system also has the following features:
! Reduced exhaust emissions
! Reduced fuel consumption
! Increased engine output
! Quick response to accelerator and brake pedal operation
! Superior startability and warm-up performance in cold weather due to corrective controls made
according to coolant and intake air temperatures
