  FEATURES EAS20170 FEATURES OUTLINE OF THE FI SYSTEM The main function of a fuel supply system is to provide fuel to the combustion chamber at the opti- mum air-fuel ratio in accordance with the engine operating conditions and the atmospheric tempera- ture.

• Page 12: Fi System

  FI SYSTEM ET2D1001 FI SYSTEM The fuel pump delivers fuel to the fuel injector via the fuel filter. The pressure regulator maintains the fuel pressure that is applied to the fuel injector at only 324 kPa (3.24 kg/cm , 46.1 psi). Accordingly, when the energizing signal from the ECU energizes the fuel injector, the fuel passage opens, caus- ing the fuel to be injected into the intake manifold only during the time the passage remain open.
