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 only 324 kPa (3.24 kg/cm
2
, 46.1 psi). Accordingly,
when the energizing signal from the ECU energizes the fuel injector, the fuel passage opens, caus-
ing the fuel to be injected into the intake manifold only during the time the passage remain 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 ener-
gized (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 (for throttle valves), throttle position sensor (for throttle cable pulley),
crankshaft position sensor, intake air pressure sensor, intake air temperature sensor, coolant tem-
perature sensor, atmospheric pressure sensor, cylinder identification sensor, lean angle sensor,
speed sensor and O
2
sensor enable the ECU to determine the injection duration. The injection tim-
ing 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 condi-
tions.
