continuously

A continuously variable transmission (CVT) is an automatic transmission that can change through a continuous range of gear ratios, typically resulting in better fuel economy in gasoline applications. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant angular velocity while the vehicle moves at varying speeds.
Thus, CVT has a simpler structure, longer internal component lifespan in theory, and potentially greater durability. Compared to traditional or standard automatic transmissions, it offers lower fuel consumption and greater environmental friendliness.
CVTs are used in cars, tractors, side-by-sides, motor scooters, snowmobiles, bicycles, and heavy equipment. The most common type of CVT uses two pulleys connected by a belt or chain; however, several other designs have also been used at times.
