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” .)
