ABSTRACT:
A system for controlling the quantity of intake air for an internal combustion engine in response to changes in air density employs a supplementary air intake passage connecting the main air intake passage on the downstream side of the carburetor throttle valve with the atmosphere. An atmospheric pressure compensation valve controls the open cross-sectional area of the supplementary air passage in response to changes in atmospheric pressure. In addition, a vacuum responsive control valve controls the open cross-sectional area of the supplementary air intake passage to pass an amount of air through the supplementary passage proportional to the amount of air passed through the main air intake passage.
