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. In the conventional carburetor system, the air-fuel ratio of the mixture that is supplied to the 
combustion chamber is created by the volume of the intake air and the fuel that is metered by the jet 
used in the respective carburetor.

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
2, 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. 
Therefore, the longer the length of time the fuel injector is...
