ABSTRACT:
A gasoline engine air valve fuel saver device, characterized in the ability to have the air valve opened automatically in circumstances where the vehicle concerned is reducing its speed, going downhill or the suction from within the carburetor is great while the engine rotation speed remains higher than 920 RPM (equivalent to the speed of 25 Kms per hour as effected by the high-speed gear shifting), so that the air may bypass the carburetor at it passes from the air filter to the intake manifold to reach the cylinders, so as to reduce the vacuum in the intake manifold and so reduce the quantity of gasoline that will enter the cylinders, to achieve a saving of fuel consumption and abatement of air pollution as well.
