Abstract
A function signal having a desired characteristic curve is generated through the logical operation on a vehicle speed signal indicative of the speed of a vehicle, a ratio signal indicative of the air-to-fuel of the mixture supplied to the engine mounted on the vehicle, and a pressure signal indicative of the pressure in the intake manifold of the engine. The position of an electromagnetic valve for adjusting the amount of fuel supplied to the engine is controlled in response to the function signal, thereby controlling the air-to-fuel of mixtures in accordance with the various driving conditions of the vehicle including the vehicle speed.
