A supercharging arrangement for an internal combustion engine where the supercharger drive is transmitted from the engine through a continuously variable transmission (CVT). The supercharging arrangement comprises a supercharger having a rotational drive input, and a transmission having a rotational drive input to receive drive from an internal combustion engine, and a rotational drive output connected to the input of the supercharger. The transmission includes a toroidal variator operatively connected between the input and the output of the transmission, wherein the variator has an output that is driven at an operating ratio from an input. The control system may operate to cause an engine to deliver an amount of torque that is indicated by the state of an input to the control system which may be automated or directly determined by a person. The variator may have a twin roller 120,122 configuration, with input 110 and output races coaxially mounted for rotation about a variator axis, and a toroidal cavity being defined between the working surfaces of the races. |
