6. EVAP canister purge valve
ENGINE AND EMISSION CONTROL SYSTEM (SFI FOR G13) 6E2-7
The fuel delivery system consists of the fuel tank (11),
fuel pump (12), fuel filter (10), fuel pressure regulator
(3), delivery pipe (2) and fuel injectors (1).
The fuel in the fuel tank (11) is pumped up by the fuel
pump (12), filtered by the fuel filter (10) and fed under
pressure to each injector through the delivery pipe
(2). As the fuel pressure applied to the injector (the
fuel pressure in the fuel feed line (7)) is always kept
a certain amount higher than the pressure in the in-
take manifold (4) by the fuel pressure regulator (3),
the fuel is injected into the intake port of the cylinder
head when the injector opens according to the injec-
tion signal from ECM (PCM).
The fuel relieved by the fuel pressure regulator re-
turns through the fuel return line (8) to the fuel tank
(11).
Also, fuel vapor generated in fuel tank is led through
the fuel vapor line (9) into the EVAP canister (5).
