Which of the following statements is true regarding the installation of piston rings on two-stroke/cycle, diesel engines as compared to four-stroke/cycle, diesel engines?（）
- AIn a two-stroke/cycle engine, the rings run hotter, requiring the end gap to be greater
- BSome provision must be made in a two-stroke/cycle engine to keep the rings from binding in the ports
- CNo 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
- DThe 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
