Abstract: An internal combustion engine is provided with air-charge or fuel-air-charge induction means which acts as a supercharger during one mode of operation and as a subcharger during another mode. The induction means is mechanically driven from the engine via a variable speed hydraulic transmission arrangement. Means are provided to appropriately change the hydraulic circuit at the moment when power flow through the hydraulic transmission changes direction. During the subcharging mode the air-charge or fuel-air-charge induction means acts as a throttle, but the energy lost in the resulting pressure drop is returned to the engine by way of the variable speed hydraulic transmission arrangement.
