27 SYSTEM COMPONENTS
The system is composed of three circuits:
A fuel circuit
B intake air circuit
C electrical circuit
28 FUEL CIRCUIT
The fuel is injected into each cylinder's intake duct,
upstream of the intake valve.
It includes: a tank, a pump, a filter, a pressure adjuster,
electro-injectors.
The electric pump "1" sucks in fuel from the tank "3" and
delivers it to the electro-injectors "2" by means of a filter.
The fuel pressure in the circuit is kept stable by the
pressure adjustor. This controls the amount of fuel flowing
back into the tank.
Note For fuel pump unit assembly, refer to sub-
section 30 of this section (Fuel electric pump
unit "1")
