what is ivt transmission
A subset of CVT designs are called infinitely variable transmissions (IVT or IVTs), in which the range of ratios of output shaft speed to input shaft speed includes a zero ratio that can be continuously approached from a defined higher ratio.n example of a true IVT is the Hydristor because the front unit connected to the engine can displace from zero to 27 cubic inches (440 cm 3) per revolution forward and zero to â10 cubic inches (â160 cm 3) per revolution reverse.
