Control & Operation第 61 / 120 题
Which sequence describes double clutching to shift into a higher gear?
a.Release the accelerator, push in the clutch and shift to neutral, release the clutch, let engine and gear speeds drop to the range for the next gear, push in the clutch and shift to the higher gear, release the clutch and accelerate
b.Push in the clutch once, shift directly to the higher gear, and release the clutch
c.Accelerate hard, shift without the clutch, then brake
d.Shift to neutral, coast until the vehicle slows, then select any gear
解析
Double clutching passes through neutral with the clutch released so engine and transmission speeds can match before the next gear is selected. Single clutching, floating gears without matching speeds, and coasting in neutral all grind gears or leave the vehicle without power control.
