A.In a two-stroke/cycle engine, the rings run hotter, requiring the end gap to be greater
B.Some provision must be made in a two-stroke/cycle engine to keep the rings from binding in the ports
C.No gap is required to exist between the ends of the ring when cold in a two-stroke/cycle engine, but a small gap is required in a four-stoke/cycle engine
D.The gaps should be staggered on either side of a piston in a two-stroke/cycle engine, while staggering is not necessary in a four-stroke/cycle engine
