General Description
Fuel Injection System Description
B823H11701001
Fuel System
The fuel delivery system consists of the fuel tank (1), fuel pump (2), fuel filters (3) and (4), fuel feed hose (5), fuel
delivery pipes (6) including fuel injectors (7) and (8), fuel pressure regulator (9). There is no fuel return hose. The fuel
in the fuel tank is pumped up by the fuel pump and pressurized fuel flows into the injectors installed in the fuel delivery
pipe. Fuel pressure is regulated by the fuel pressure regulator. As the fuel pressure applied to the fuel injectors (the
fuel pressure in the fuel delivery pipe) is always kept at absolute fuel pressure of 300 kPa (3.0 kgf/cm
2
, 43 psi), the fuel
is injected into the throttle body in conic dispersion when the injector opens according to the injection signal from the
ECM.
The fuel relieved by the fuel pressure regulator flows back to the fuel tank.
