Automotive engineers are working on improving cars by developing a type of transmission called Continuously Variable Transmission (CVT). This system has infinite gear ratios, reduces power loss, and provides smooth gear shifts. The researchers studied different factors like fly mass and pulley springs to see how they affect the engagement speed of the transmission. They also created a manual model of the CVT to test their findings. The experiments were conducted on a Baja SAE vehicle, showing how changing these factors affects the speed at which the transmission engages.
