FUEL FILTER

Legend

(1) Priming Pump
(2) Fuel Filter Cartridge

A cartridge type fuel filter is used along with the piston
type fuel pump on the high pressure oil pump.
The fuel filter removes foreign material from the fuel
before it reaches the fuel pump.
A diaphragm type priming pump is installed at the top of
the fuel filter. It is used during the air bleeding
procedures.

INJECTOR ASSEMBLY

Legend

(1) Oil  Passage
(2) Fuel Passage

1. Construction of Fuel Injector

The fuel injector is comprised of the solenoid
section, hydraulic line, and fuel line. Fuel injection is
controlled by the continuity time signal and
continuity start timing signal sent by the ECM
(Electronic Control Module) to the solenoid.

2. Working of Fuel Injector

1) The ECM detects the working of the engine from

its input signals, such as engine speed
accelerator throttle opening, and engine coolant
temperature, sending the optimal signals to the
solenoid.
