Abstract
In a fuel control system for an internal combustion engine comprising a sensing vane swingably disposed in an intake pipe of the engine and adapted to be angularly displaced in proportion to the flow rate of the intake air and a fuel control device in response to the angular displacement of said sensing vane for controlling the rate of fuel to be supplied to the engine in proportion to the flow rate of the intake air, a plurality of pressure-responsive actuators are operatively connected to said sensing vane and adapted to actuate in response to vacuum or air-pressure signals representative of the conditions of the engine such as acceleration and deceleration, the temperature of the engine and the ambient air pressure, respectively, to control the angular displacement of said sensing vane so as to change the ratio of the rate of fuel to be supplied to the engine to the flow rate of the intake air, whereby the air-fuel ratio is optimized according to engine conditions.
