举一反三
- In<br/>a four-strokes diesel engine, the cycle requires four separate<br/>strokes of the piston, i.e. ____. A: suction B: compression C: expansion D: exhaust
- In diesel engines， the four basic events (intake， compression， power and exhaust) are performed once in （）.
- The four strokes in the engine are, in order of<br/>occurrence((_____)) A: intake, power, exhaust, and compression B: intake, power, compression, and exhaust C: intake, compression, power, and exhaust D: intake, exhaust, power, and compression
- Which one implies the corect order of the four strokes? A: intake, exhaust, power, and compression B: intake, power, compression, and exhaust C: intake, power, exhaust, and comression D: intake, compression, power, and exhaust
- One of the differences between a two-stroke engine and a four-stroke engine is,（） A: a two-stroke engine works without exhaust operation B: a two-stroke engine works without compression stroke C: a two-stroke engine works without expansion stroke D: a two-stroke engine works without suction operatio
