2. An internal combustion engine having a cylinder formed of a fixed and a shiftable section, a jacket surrounding said shiftable section and terminating at one end in said fixed section, said jacket and said shiftable section forming a passage for the supply of the combustible mixture, said jacket having its inner face' provided with screw threads, and screw-threaded ribs carried by the shiftable section and engaging the screw threads of the jacket for adjustably connecting the shiftable section to the jacket, thereby permitting the increasing and decreasing of the width of said passage.

3. An internal combustion engine comprising a cylinder formed of a fixed. and a shiftable section, a jacket surrounding said shiftable section and having its upper ortion extending towards and connecter to said fixed section, the upper portion of said jacket being substantiallyoconical in cross section, said shiftable section of the cylinder having its upper portion corresponding in contour to the shape of the upper portion of said jacket, said jacket and said shiftable section torming a supply passage for the \coinbustible char e, and means for adjustabl connecting the shiftable section to the jac et for increasing and decreasing the width of the passage.
