3. DESCRIPTION OF FUEL SYSTEM
This engine is equipped with Electronic Fuel
Injection system (FI system) integrated with
ECU (Engine Control Unit).
The FI system consists of throttle body
(2-barrel), ECU, MAP (Manifold Air Pressure)
sensor, injector, fuel pressure regulator,
temperature sensor, electric fuel pump, and
pulsation damper.
The fuel system is calibrated after careful testing for optimum all-round performance (including
starting, acceleration, fuel consumption, output power characteristics).
The throttle body monitors manifold air pressure and engine temperature at start up and performs
the choke function automatically.
While the engine is in operation, the throttle body monitors engine speed, manifold air pressure,
and engine temperature to ensure proper engine performance.
(For further information, refer to page 16, section “6 .THROTTLE BODY”.)
