Understanding Continuously Variable Transmissions

What is the primary advantage of a Continuously Variable Transmission (CVT) compared to a conventional automatic transmission?

• Improved fuel efficiency and smoother acceleration

• Higher top speed and better engine braking

• Reduced engine lifespan and increased maintenance costs

• Increased gear-shifting noise and power loss

Which of the following components is essential for the operation of a belt-driven CVT?

• Torque converter and planetary gears

• Clutch plate and flywheel

• Pulley system and metal belt

• Countershaft and synchronizer rings

How does a CVT adjust the gear ratio?

• By engaging different sets of gears

• By varying the diameter of the pulleys

• By switching between high and low gear modes

• By changing the clutch pressure

What type of vehicles commonly use CVT systems?

• Heavy-duty trucks and racing cars

• Motorcycles, scooters, and hybrid cars

• Manual sports cars and diesel locomotives

• Large off-road construction vehicles

What is a disadvantage of CVT compared to traditional automatic transmissions?

• Higher mechanical complexity and rough gear shifts

• Increased weight and poor fuel economy

• Limited torque capacity and potential overheating issues

• Inability to operate in hybrid or electric vehicles
