Apparatus for supplying high pressure gas to an engine, to operate the engine, comprising in combination a gas pressurizer having a low gas pressure inlet to receive inlet gas, as for example discharge gas from the engine, and a high gas pressure outlet to deliver supply gas at high pressure to the engine, the pressurizer including a rotary body defining a gas flow channel that extends about an axis in a spiral of decreasing radius, and a drive operatively connected with the body to rotate the body about an axis, at high velocity, thereby to effect gas flow and pressure increase, along the channel, for supply to the engine via an outlet from the pressurizer.
