更多“In the two stroke diesel engine, it is designed so that the oil impingement is timed to proceed only on the piston ring belt during（）”相关的问题
A、two crankshaft revolutions in a two-stroke/cycle engine B、two power strokes in a two-stroke/cycle engine C、one power stroke in a two-stroke/cycle engine D、two piston strokes in a two-stroke/cycle engine
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
