3) High pressure pipe (fuel pipe)
Fuel line transfers high pressure fuel.
Accordingly, it is made of steel to endure
intermittent high frequency pressure
changes that occur under maximum system
pressure and injection stops. Injection lines
between rail and injectors are all in the same
length; it means the lengths between the rail
and each injector are the same and the
differences in length are compensated by
each bending.
No.1 and 3 cylinder No. 5 cylinder
No.2 and 4 cylinder
4) Injectors
The fuel injection device is composed of
electrical solenoid valve, needle and nozzle
and controlled by engine ECU. The injector
nozzle opens when solenoid valve is
activated to directly inject the fuel into
combustion chamber in engine. When
injector nozzle is open, remaining fuel after
injection returns to fuel tank through return
line.
Pressure limit valve, fuel returned by low
pressure and fuel used for high pressure
pump lubrication also return to fuel tank
through return line.
5) Fuel filter replacement
Fuel filter change interval: every 30,000 km
Water separation interval: every 10,000 km (same with engine oil change interval)
Never reuse the removed fuel filter -
