Fuel Injection System Description

Fuel System
The fuel delivery system consists of the fuel tank (1), fuel pump (2), fuel filter (3), fuel feed hose (4), fuel delivery pipes
(5) including fuel injectors (6) and (7), fuel pressure regulator (8). 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 approx. 294 kPa (2.9 kgf/cm
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.
