Control & Operation第 62 / 120 题
When downshifting, what do you do differently compared with upshifting?
a.You skip neutral entirely
b.While in neutral with the clutch released, you press the accelerator to raise engine rpm before selecting the lower gear
c.You hold the clutch down through the whole shift
d.You apply the service brakes throughout the shift
解析
A lower gear turns faster at the same road speed, so engine speed must be increased in neutral to match it. Skipping neutral, riding the clutch, or braking through the shift prevents the speeds from matching and can damage the transmission.
