the cylinder as clearly shown in Figure 3.

The incoming fuel is injected through the intake ports of the cylinder and the sleeve valve means, and the flow of the vaporized fuel is so controlled as to break up the tendency for this fuel to swirl within the cylinder. This is accomplished by providing deflecting means preferably carried by the cylinder head structure which deflects the incoming fuel and imparts thereto a directional force causing a portion of the fuel to flow in one direction and the remainder to flow in the opposite direction, these fuel streams being adapted to meet and set up a turbulence that counteracts or modifies the tendency of the fuel to swirl. With reference to Figures 1 to 4 inclusive, it is noted that the annular chamber 21 is constructed in the lower portion of the cylinder head structure, this annular chamber 21 extending around the circumferential lower edge of the reentrant head portion of the cylinder head structure adjacent to the cylinder wall and preferably within the limit of the sleeve valve means. Directly in line with the cylinder intake port, the cylinder head portion is provided with the recesses or grooves 22,

22a which are inclined to the vertical axis of The incoming fuel mixture admitted through the sleeve intake port is thus divided, a portion thereof being deflected by the groove 22 while streams will meet at or near that portion of the cylinder or combustion chamber diametrically opposite to the intake port.

Preferably, the major portion of the fuel mixture introduced into the cylinder is acted upon and so divided as to direct the divided portions 'of the fuel mixture to flow in diverging directions; i. e., the fuel mixture divided portions tend to swirl in opposite directions and counteract or modify each other to fully eliminate the swirl or so control the swirl as to provide any desired resultant swirl. In the illustrated embodiment of my invention I have shown a construction in which substantially all the fuel mixture is acted upon and divided in such a way that portions of substantially equal mass are 'swirled in opposite directions, but I wish it to be understood that I am not limited to an equal mass distribution, since in some instances it may be. more desirable to distribute or divide the incoming fuel mixture into portions of unequal mass for controlling the swirl to any desired de- 'gree.

Further, the construction may be such as to control the swirl by an arrangement whereby said fuel mixture portions may be caused to swirl with different velocities. Thus broadly my invention relates to means for controlling 'or modifying the swirl and it may be noted that this action preferably takes place substantially throughout the entire intake stroke of the engine.

In Figures 5 to '7 inclusive a modified form of construction is illustrated which shows a partition or dividing flange 25 preferably carried by the cylinder head structure and cast integrally therewith. Part of the incoming fuel is directed to one side of this dividing flange or partition 25 while the remainder is directed to the other side of the partition. It is noted that the side faces of the dividing or partition wall 25, form the ends of the annular chamber 21, the ends of this annular chamber being inclined to the axis of the cylinder as shown in Figure 5 so that the fuel stream directed into the annular chamber at one side of the wall or partition 25, is given a directional force, causing the same to flow in a direction opposite to the flow of the fuel delivered to the combustion chamber on the opposite side of this dividing wall or partition 25. It is noted that the cylinder head, as illustrated in the Figures 5 to 7 inclusive, and described above is provided with only one partition or dividing wall for imparting directional forces to the incoming fuel stream.

In Figures 8 to 10 inclusive, a further modified construction is illustrated and shows the cylinder head structure provided with the flanges or ribs 30 that are inclined at an angle to the cylinder axis as shown in Figure 8, these inclined ribs being spaced from the inside surface of the sleeve valve means and being preferably constructed of just sufficient depth as to induce the incoming fuel to flow in the desired direction.

It will thus be noted that I have provided a deflecting means which may be contained within the cylinder and also within the sleeve valve means mounted within the cylinder, which will be engaged by the stream of incoming fuel. This deflecting means will divide the fuel stream and so direct the same as to cause the same to flow in opposite directions, thereby in some instances set ting up a turbulence within the cylinder so that the vaporized fuel will not have the tendency to swirl and in other instances modifying the swirl to any desired predetermined degree.

Further, it will be noted that I have provided a very simple means for controlling the swirl of the fuel mixture for accomplishing the purpose of my invention described above.

It will be apparent to those skilled in the art to which my invention pertains, that various modifications and changes may be made therein without departing from the spirit of my invention or from the scope of the appended claims.
