Compared to four-stroke/cycle engines, two-stroke/cycle diesel engines have the disadvantage of ()
A、less even torque
B、higher cylinder head temperatures
C、fewer power strokes per revolution
D、greater weight/size requirements
A、less even torque
B、higher cylinder head temperatures
C、fewer power strokes per revolution
D、greater weight/size requirements
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.dim str as string B、B.dim str as string(256) C、C.dim str as string[256] D、D.dim str as string*256
