A puffing swirler for use in an internal combustion engine. The puffing swirler causes the air and vaporized fuel mixture to have a controlled high velocity swirling action within the piston cylinder of the engine to provide improved high efficiency combustion of the fuel therein. The puffing swirler includes a flow directing deflector movable with the inlet valve and defining a plurality of swirl-inducing passages. A flow control device is provided for preventing delivery of the fuel fluid to the inlet port until the piston has moved substantially from the top position toward the bottom position thereof, thereby producing a substantial preselected pressure differential between the fluid supply and the cylinder to effect the desired puffing delivery of the fluid to the cylinder. Structure may be provided to releasably retain the flow control device in the full open position as during high speed operation of the engine. The puffing swirler may further include structure to provide delivery selectively through one or more swirl-inducing passages of the flow directing device. The flow control device may be made adjustable for adjusting the pressure differential at which the puff delivery takes place.
In an internal combustion engine having means defining a cylinder defining an inlet port and an outlet port, a piston disposed in said cylinder for reciprocation between a top position adjacent the inlet port and a bottom position spaced therefrom, means for supplying a combustible fluid comprising a mixture of air and vaporized fuel to said inlet port, and a valve movably positionable for selectively closing said inlet port, the improvement comprising:
