Abstract

A function generator is fed input signals corresponding to at least two different engine operating parameters, such as the position of the accelerator pedal and the engine rpm, the function generator, in dependence on these input signals, controlling the amount of fuel supplied to the cylinder so as to maintain a desired excess air coefficient lambda for each operating condition of the engine. In one form of the invention, the function generator controls the fuel and air supplied, as well as the ignition timing.
