Abstract
A carburetor device for an internal combustion engine is disclosed. The device includes a well adjacent to the intake manifold for holding a quantity of liquid fuel. Perforated tubing is in the bottom of the well, and air under pressure is selectively supplied to the tubing to froth the liquid fuel and produce fuel vapor. The amount of the tubing receiving air under pressure is varied in accordance with fuel demand. The fuel vapor is mixed with ambient air and directed into the intake manifold. The system includes a storage tank for providing the air under pressure, and a pump to supply air to the storage tank.
