OUTLINE OF 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. In a 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 chamber. 
Despite the same volume of intake air, the fuel volume requirement varies with the engine operating 
conditions, such as acceleration, deceleration, or operation under a heavy load. Carburetors that 
meter the fuel through the use of jets have been provided with various auxiliary devices, so that an 
optimum air-fuel ratio can be achieved to accommodate the constant changes in the operating con-
ditions of the engine.
As the requirements for engines to deliver more performance and cleaner exhaust gases increase, it 
becomes necessary to control the air-fuel ratio in a more precise and finely tuned manner. To 
accommodate this need, this model has adopted an electronically controlled fuel injection (FI) sys-
tem in place of a conventional carburetor system. This system can achieve an optimum air-fuel ratio 
required by the engine at all times by using a microprocessor that regulates the fuel injection volume 
according to the engine operating conditions detected by various sensors.
Adoption of the FI system has resulted in a highly precise fuel supply, improved engine response, 
better fuel economy, and reduced exhaust emissions.
