A torque converter is a fluid coupling that transfers rotational power from a prime mover, usually an engine, to a driven load. It is used in vehicles with automatic transmissions to allow the engine to run at a higher speed than the wheels, while still providing the necessary torque to move the vehicle. Torque converters are also used in industrial applications, such as pumps and compressors.
There are many factors to consider when choosing a torque converter, including the engine’s power and torque, the vehicle’s weight and gear ratio, and the desired performance characteristics. The right torque converter will help the engine to operate at its optimum efficiency and will provide the desired level of performance.
