PROBLEM TO BE SOLVED: To provide an engine supercharger which can improve responsiveness in acceleration.SOLUTION: This engine supercharger 10 comprises an exhaust turbine 30 connected to a compressor 32, a drive turbine 48 connected to the exhaust turbine 30, and a pressure accumulation tank 36 for supplying auxiliary air to the drive turbine 48 in acceleration. Then, the supercharger makes the drive turbine 48 promote the rotation of the exhaust turbine 30 by injecting auxiliary compressed air which is pressure-accumulated in the pressure accumulation tank 36 in the acceleration, and supplements an intake air amount to an engine 14 necessary for the acceleration by the compressor 32. |
