D、cycle of two events
A、crankshaft revolution
B、mechanical cycle of operation
C、period of two combustion cycles
D、cycle of two events
A、two strokes of the piston B、four strokes of the piston C、one revolution of the crankshaft D、four revolutions of the crankshaft
A、once every crankshaft revolution B、once every two crankshaft revolutions C、once every piston stroke D、twice every piston stroke
A、crankcase pressure B、compression pressure C、scavenge pressure D、exhaust manifold pressure
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
A、A.opposed-piston engine B、B.double-acting engine C、C.two-stroke/cycle engine D、D.four-stroke/cycle engine
