Design and Performance Study of Continuously Variable Transmission (CVT)

Abstract

Nowadays, automakers have invested in new technologies in order to improve the efficiency of their products. A Continuously variable transmission (CVT) offers a continuum of gear ratios between desired limits, which consequently enhances the fuel economy and dynamic performance of a vehicle by better matching the engine operating conditions to the variable driving scenarios. Automakers have taken an important step toward achieving the objective by designing continuously variable transmission systems (CVT) to continuously adapt the power of the engine with the external load according to the optimum efficiency curve of engine and reducing fuel consumption besides making smooth start up and removing the shock caused by changing the gear ratio and making more pleasurable driving.
