Abstract
An altitude compensating apparatus for use with an engine includes a bellows in which the air or gas is confined at a predetermined suitable pressure. The bellows expands as the atmospheric pressure lowers on the high lands. A first valve operatively connected to the bellows opens air outlet to introduce the air into air bleeds of a carburetor with the expansion of the bellows thereby to reduce the fuel mixed with the air in the carburetor. A second valve connected to the bellows operates to introduce the negative pressure into a vacuum advancer of a distributor with the expansion of the bellows thereby to advance the ignition timing of the engine.
