Power Conversion in Automatic Transmission

Explain the operation of a torque converter in an automatic transmission.

• A torque converter in an automatic transmission uses gears to transfer power from the engine

• A torque converter in an automatic transmission transfers power from the engine to the transmission using fluid dynamics, enabling the engine to run even when the vehicle is stopped.

• A torque converter in an automatic transmission relies on magnetic fields for power transfer

• A torque converter in an automatic transmission converts sound waves into power

What is the purpose of a stator in a torque converter?

• To decrease torque multiplication

• To increase fuel efficiency

• To reduce fluid flow

• To redirect fluid flow and increase torque multiplication

How does a torque converter help in power conversion in an automatic transmission?

• A torque converter helps in power conversion by reducing power output at high speeds to prevent overheating.

• A torque converter helps in power conversion by converting electrical energy into mechanical energy.

• A torque converter helps in power conversion by using fluid coupling to transfer power from the engine to the transmission and multiplying torque to increase power output at low speeds.

• A torque converter helps in power conversion by using mechanical gears to transfer power from the engine to the transmission.

Describe the lock-up clutch function in a torque converter.

• The lock-up clutch function in a torque converter is to disengage the turbine and impeller.

• The lock-up clutch function in a torque converter is to increase slip and decrease efficiency.

• The lock-up clutch function in a torque converter is to reduce torque output.

• The lock-up clutch function in a torque converter is to mechanically lock the turbine and impeller together, eliminating slip and increasing efficiency.

What are the advantages of using a torque converter in an automatic transmission?

• Increases fuel efficiency

• Causes jerky acceleration

• Requires frequent maintenance

• Allows engine to run while vehicle is stopped, provides smooth acceleration, reduces wear on transmission components

How does a torque converter affect fuel efficiency in a vehicle?

• A torque converter reduces fuel efficiency by causing more friction in the transmission system.

• A torque converter has no impact on fuel efficiency in a vehicle.

• A torque converter can improve fuel efficiency by allowing the engine to keep running while the vehicle is stopped and enabling smoother acceleration.

• A torque converter increases fuel efficiency by directly powering the wheels without using the engine.

Discuss the differences between a torque converter and a manual clutch.

• Torque converters transfer power automatically without manual intervention, while manual clutches require the driver to engage and disengage the connection between the engine and transmission.

• Torque converters require manual shifting, while manual clutches do not

• Torque converters are more fuel-efficient than manual clutches

• Torque converters are only found in electric vehicles, while manual clutches are used in traditional cars

Explain the role of the torque converter in transmitting power from the engine to the transmission.

• The torque converter increases fuel efficiency by directly connecting the engine to the transmission

• The torque converter allows the engine to transfer power to the transmission smoothly through hydraulic pressure.

• The torque converter is responsible for regulating the air intake in the engine

• The torque converter functions as a cooling system for the transmission fluid

What are the common issues that can arise with a torque converter in an automatic transmission?

• Overheating, fluid leaks, shuddering or slipping, failure to engage or disengage properly

• Rust buildup, electrical issues, gear slippage

How does a torque converter contribute to smooth acceleration in a vehicle?

• By allowing the engine to run while the vehicle is stopped and multiplying torque output to the transmission.

• By reducing fuel efficiency and increasing engine wear

• By limiting the engine's power output and decreasing torque

• By disconnecting the engine from the transmission during acceleration
