ABSTRACT:
A fuel control system for use in an internal combustion engine wherein the combustion device thereof comprises a main combustion chamber and an auxiliary combustion chamber provided therein with an ignition plug, the main and auxiliary combustion chambers communicating with each other through a through-hole. A rich mixture of gasified fuel and air is supplied to the auxiliary combustion chamber and a lean mixture of gasified fuel and air is supplied into the main combustion chamber and the mixture in the main combustion chamber is ignited by the flames produced in the auxiliary combustion chamber. A main air intake passageway and an auxiliary air intake passageway are provided and communicated respectively with the main combustion chamber and the auxiliary combustion chamber, and a fuel control system capable of varying the pressure for fuel supply in accordance with the negative pressure of a Venturi flume provided in the main air intake passageway and a fuel passageway for supplying the fuel controlled by said fuel control system to the main and auxiliary air intake passageways respectively at a predetermined distribution ratio, thereby making it possible to produce predetermined volumes of mixtures of gasified fuel and air respectively in the main and auxiliary air intake passageways.
