remain open is variable according to operating conditions. The duration of each
injection is calculated by the engine ECM using data received from the various
sensors in the system.
Ignition coils
- situated above the camshaft cover, attached to the frame. There
are two coils fitted, one for each of the spark plugs. The engine ECM controls the
point at which the coils are switched on and off. In calculating the switch-on time,
the engine ECM allows sufficient time for the coils to charge to a level where a
spark can be produced. The coils are switched off at the point of ignition, the
timing of which is optimised for good engine performance.
Main power relay
- situated behind the left hand side panel. When the ignition is
switched on, the main power relay is powered up to provide a stable voltage
supply for the engine ECM.
Fuel pump
- situated inside the fuel tank. The electric pump delivers fuel into the
fuel system, via a pressure regulator, at a constant 3.5 bar pressure. The pump is
run continuously when the engine is operating and is also run briefly when the
ignition is first switched on to ensure that fuel at 3.5 bar pressure is available to
the system as soon as the engine is cranked. Fuel pressure is controlled by a
regulator also situated inside the fuel tank.
Cooling fan
- situated behind the radiator. The engine ECM controls switching on
and off of the cooling fan in response to a signal received from the coolant
temperature sensor. When the coolant temperature rises to a level where the
cooling effect of natural airflow is insufficient, the cooling fan is turned on by the
engine ECM. When the coolant temperature falls sufficiently, the engine ECM
turns the cooling fan off. The fan only becomes operational when the engine is
running. It will not operate at any other time.
Note
In this system, the starter lockout system (clutch switch, neutral switch, side
stand switch) all operate through the engine management ECM.
