Purpose, Function
Supplies power to the PCM for the fuel injector and spill valve control solenoid valve operation.
Construction
The fuel injector relay is installed in the relay and fuse block.

Operation
When the ignition is switched ON, the battery voltage is supplied to the coil and the contact point is on, thus the battery voltage is supplied to the PCM.

Fail-safe
Function not equipped.

Electric Variable Valve Timing Control
Outline
The PCM determines the optimum intake valve timing according to the engine
operation conditions, and sends the motor drive signals to the electric variable
valve timing driver. With the adoption of the electric drive system, variable
intake valve timing can be controlled with ...
High Pressure Fuel Pump
Purpose, Function
Applies pressure to fuel sent from the fuel pump equipped on the fuel tank,
and then pumps it to the fuel delivery pipe.
Fuel is sectioned and pumped by the up and down movement of the piston caused
by the rotation of the cam installed to the rear end of the ex ...
