Torque converter which models the transmission fluid behaviour based on fluid mechanics. Torque converter that works based on a K-factor input table. Table based – K-factor (C and MPC formulations also exist). Modern torque converters use a lock-up clutch to reduce the energy losses within the coupling fluid by mechanically locking the turbine to the impeller.At this stage, the vehicle speed has increased, hence, the turbine reaches approximately 90% of the speed of the impeller and the torque multiplication ceases.The brakes are no longer applied and the acceleration pedal is pressed, as a result, the impeller rotates faster and produces torque multiplication working in conjunction with the turbine.

The impeller or pump receives the mechanical energy produced by the engine, but the turbine does not rotate because the brakes are still applied.The torque converter consists of a turbine, a pump or impeller, a stator and a lock-up clutch (included on modern torque converters only) as can be seen in Figure 1.

Now comes the important question that resumes the topic of this blog post, but what about automatic transmissions, do they use clutches as well? These types of transmission use a totally different device called “ Torque Converter” although the same concept is implemented, which is to decouple or allow relative angular velocity between the engine and the gearbox. This said, the clutch can provide a smooth engagement (dependent on acutation!) between a spinning engine and a non-spinning driveline by disconnecting the engine from the gearbox input shaft. The engine is a component that when the vehicle is in use is spinning most of the time, however, we may not want to be spinning the vehicle driveline at the same speed of the engine particularly on pull-away.

We all know almost by instinct that manual transmissions have a clutch to operate correctly, a device that allows to engage or disengage gears according to the vehicle speed.
