1. The power train has two maan functions :

it conveys powerfrom the engine to the wheels , and it changes the amount of torque2. The power train consists of an engine , a transmission ,a clutch , a drive shaft and differential

3. The feature of a manual transmission is to deliver enginepower to the front wheels and rear wheels 

4. manual transmissions usually have five speeds , which means that the output shaft can rotate faster than the input

5. There are several basic components in the clutch , suchas the flywheel , clutch disk , pressure plate , release bearing and linkage.

6 Automatic transmissions are used not only in many rear-wheel-dnve and four-wheel-dnve ve- lcles, but In most front-wheel-dnve ones
