ABSTRACT:
Gas "Eggconomizer" is a visual display device which indicates the rate of fuel consumption in an internal combustion engine. The device is loaded on the dash of an automobile and is connected by a tube to the intake manifold of the engine. The device includes an egg-shaped transparent container, an egg-shaped core with an elastic coating within the container, a support at the bottom of the container and a tube connected near the top of the container. When the device is subjected to the intake manifold vacuum, the upper half of the elastic coating reacts by varying in size to reflect the magnitude of the vacuum. High vacuum, which indicates minimal gas consumption, increases the size; while low vacuum, which indicates increased gas consumption, decreases the size. The device can be used to improve gas conservation driving habits.
