FI SYSTEM
The fuel pump delivers fuel to the injector via the fuel filter. The pressure regulator maintains the fu-
el pressure that is applied to the injector at 324 kPa (3.24 kg/cm
2
, 46.1 psi) higher than the intake
manifold pressure. Accordingly, when the energizing signal from the ECU energizes the 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 injector is energized (injection
duration), the greater the volume of fuel that is supplied. Conversely, the shorter the length of time
the injector is energized (injection duration), 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, crankshaft position sensor, intake air pressure sensor, intake air temper-
ature sensor, and coolant temperature sensor enable the ECU to determine the injection duration.
The injection timing is determined through the signal 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.
