Abstract
A supercharging arrangement for an internal combustion engine is disclosed. 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 variator operatively connected between the input and the output of the transmission, which variator has an output that is driven at an operating ratio from an input. There is a control system that operates to cause an engine to deliver an amount of torque that is indicated by the state of an input to the control system. The control system is further operative to set the operating ratio of the variator.
