A、most critical in a four-stroke cycle diesel engine B、most critical in a two-stroke/cycle diesel engine C、most critical in a four-stroke/cycle diesel engine if it is turbocharged D、of equal importance in a two-stroke/cycle diesel engine as in a four-stroke/cycle diesel engine
A、The direction of pressure on the journal in four-stroke engine is continuously B、positive feed lubricators are installed on all bearings of four-stroke engine, whereas as a splash feed system is used on tow-stroke engine C、four-stroke engines usually utilize a heavier grade of oil than tow-stroke engines D、Low-stroke engines usually consume less lube oil than four-stroke engines
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
