Abstract
An internal combustion engine (20) has two exhaust valves (24, 25) for each combustion chamber, to permit separation of blow-down and expulsion phases of an exhaust stroke. The separate exhaust streams are directed to different geometries of an exhaust turbocharger (30), so as to make best use thereof. Variable exhaust valve timing, and bypass passage for the exhaust streams are disclosed.
