The document discusses the torque converter, which transfers torque from an engine to a transmission input shaft. It has three main parts: an impeller, turbine, and stator. Torque converters use fluid coupling to multiply engine torque without a direct mechanical link. Originally, fluid coupling led to a problem, but introducing a stator solved this issue. The torque converter operates in two phases - a torque multiplication phase using stator locking and a coupling phase with freewheeling stator. It finds applications in automatic transmissions and industrial power transmission. A limitation is that it cannot be used with manual transmissions due to its complex fluid coupling design.

8. SOLUTION
Introduce a STATOR

9. Phases of operation
Phase I - Torque
Multiplication Phase:
 Low Impeller Speed
 Stator is locked into
place by its one-way
clutch
 Vortex fluid flow within
the converter
Phase II - Coupling Phase:
No torque multiplication
Stator is freewheeling
Rotary flow within the
converter

10. Applications
Automatic Transmission Systems in
automobiles
Industrial Power Transmission
Drag Racing Cars(eg. Dodge Charger)

11. limitations
• Cannot be applied to Manual Transmission
• Expensive Assembly
