Abstract
An air assist device comprising a plurality of air intake ports formed in the inner wall of an intake duct around a throttle valve. An assist air chamber is formed above the air intake ports and an assist air outflow port is formed in the assist air chamber. To allow the liquid substances flowing from the air intake ports to the assist air chamber to flow down to the assist air outflow port by gravity, the bottom wall of the assist air chamber descends toward the assist air outflow port.
