Quiz -1 Intro to Automobiles

Which of the following best describes the main advantage of a dual-clutch transmission (DCT) over a manual transmission?

• Higher torque capacity

• Better fuel efficiency in all cases

• Faster gear shifts with minimal power loss

• Lower cost and complexity

Which component in a manual transmission is responsible for disengaging the engine from the wheels when shifting gears?

• Synchronizer

• Clutch

• Flywheel

• Gear lever

Wankel engine uses a (a)   instead of pistons to convert pressure into rotating motion.

Why is torque more important than horsepower when towing a heavy load?

• Torque represents the speed of the vehicle

• Torque is needed to overcome inertia

• Horsepower improves fuel economy

• Horsepower determines low-end force

In a DCT (Dual Clutch Transmission), why are shifts faster than in a manual?

• Because it uses a torque converter

• Because both gear sets are always engaged

• Because there’s no clutch at all

• Because it uses electric motors

In a 4-stroke engine, the power stroke occurs immediately after the (a)   stroke.

Which transmission do you prefer for spirited driving?

• Manual

• DCT

• Torque Converter

• CVT

Why do CI engines generally offer better fuel efficiency than SI engines?

What’s a key disadvantage of straight-cut gears?

• High manufacturing cost

• High noise levels

• Low torque capacity

• Excessive weight

Horsepower is a function of torque and (a)   .
