Brown, S E

This patent describes an improvement in an engine having a cylinder, an intake port for admitting an air-fuel mixture to the cylinder, and an intake manifold coupled with the cylinder to provide a flow passage to the intake port for the air-fuel mixture. The improvement comprising: means for presenting a reservoir in the intake manifold for collecting liquid fuel that liquifies from the air-fuel mixture; a venturi having a restricted throat and low and high pressure sides on opposite sides of the throat; means for mounting the venturi in the flow passage with the low pressure side located downstream from the high pressure side; and means for providing a passage having an inlet end communicating with the reservoir to receive the liquid fuel therefrom and an outlet end opening into the low pressure side of the venturi to deliver the liquid fuel into the air-fuel mixture following through the venturi, thereby effecting atomization of at least some of the liquid fuel to achieve more complete combustion thereof in the cylinder.
