FI SYSTEM
The fuel pump delivers fuel to the fuel injector via the fuel filter. The pressure regulator maintains the
fuel pressure that is applied to the fuel injector at 324 kPa (3.24 kgf/cm², 47.0 psi). Accordingly, when
the energizing signal from the ECU energizes the fuel injector, the fuel passage opens, causing the fuel
to be injected into the intake manifold only during the time the passage remains open. Therefore, the
longer the length of time the fuel injector is energized (injection duration), the greater the volume of fuel
that is supplied. Conversely, the shorter the length of time the fuel injector is energized (injection dura-
tion), the lesser the volume of fuel that is supplied.
The injection duration and the injection timing are controlled by the ECU. Signals that are input from the
throttle position sensor, accelerator position sensor, coolant temperature sensor, lean angle sensor,
crankshaft position sensor, intake air pressure sensor, intake air temperature sensor, rear wheel sensor
and O
2
sensors enable the ECU to determine the injection duration. The injection timing is determined
through the signals from the crankshaft position sensor. As a result, the volume of fuel that is required
by the engine can be supplied at all times in accordance with the driving conditions.
