CVT
• CVT allows for the operation at the lowest possible speed and highest possible
load, partially avoiding the low efficiency region of the engine map.
• A continuously variable transmission (CVT) transfers power through a range
of speed/torque ratios from engine input to output, continuously without
interruption
• Contrast with either manual or conventional automatic transmissions that use
discrete ratios and normally disengage when changing ratio
• The CVT category includes infinitely variable transmissions (IVT) that give a
zero output speed within the operating range
