Abstract: Traditional engine use carburetor instead of fuel injection. The carburetor uses direct mixing of air and fuel into the engine compare to fuel injection that had a control system that adjust the volume of air to fuel mixture entering the engine. The fuel consumption is depending on the air to fuel ratio that is being injected into engine by injectors. Nowadays the price of the fossil fuel had been increase drastically compared to the last five years. The combustion of the engine has a major impact to the value of the Air-Fuel Ratio (AFR). When the air to fuel ratio is not close to the stoichiometry value, then the fuel consumption is not economical, and the engine is not in their optimum condition. An optimum and economical engine performance give a result in a decrease in fuel consumption thus reducing the carbon monoxide (CO) and hydrocarbon (HC) into the atmosphere. Thus, this paper presents the system identification on fuel control system for controlling the air fuel ratio. Hence the parameters and relationship of the air fuel ratio can be reconnoitering.
