ABSTRACT:
A device for the regulation of the air-fuel mixture of an internal combustion engine, comprising two capsules, each divided into two chambers by an element which is movable in response to a pressure difference between the two chambers, the two movable elements being connected to each other and to a valve which regulates a gas inlet to the manifold, the two chambers of one capsule being subject respectively to the static and dynamic pressures in an inlet pipe to the manifold and the two chambers of the other capsule being subject to the pressure in the manifold and a valve for altering the pressure in one of the four chambers in response to the composition of the exhaust gases.
