ABSTRACT:
A process and related apparatus for regulating the fuel-air mixture delivered to the combustion chambers of an internal combustion engine by the admission of auxiliary air the quantity of which corresponds with the quantity of the aspirated fresh air forms the subject of this invention. An air bypass line is provided for bypassing a venturi constriction disposed in a suction tube upstream of a throttle flap valve. Associated with the air bypass line are a pressure regulating valve, a bypass throttle device and a control circuit including a pair of shut-off valves, or alternatively a three way valve, with an appropriate control for controlling the valves and accordingly the reduced pressure produced by the venturi constriction, which is communicated to the bypass throttle device, or the control pressure of the pressure regulating valve. With the noted control, the reduced pressure or the control pressure of the pressure regulating valve may be varied according to the operational behavior of the engine, and as a result control the auxiliary air flow through the air bypass line.
