PROBLEM TO BE SOLVED: To provide a turbocharger capable of improving its durability. SOLUTION: A hull 14 and a deck 15 of a compact planing boat are watertightly formed, and a space 16 in the hull is formed by blocking an opening part of the deck by a sheet 12. Intake ducts 18, 19 for introducing atmospheric air in the outside of the hull are provided in this sapce, and the turbocharger 140 connected with an engine 20 and its exhaust manifold is provided in the space 16. This turbocharger 140 is arranged above openings 18a, 19a in the hull of the intake ducts. A water jacket is formed in a casing of a turbine part and an oil jacket is formed in its bearing casing in the turbocharger to supply cooling water into the water jacket and cooling oil into the oil jacket. Cooling water is supplied into the water jacket through another turbocharger cooling water passage independent from the other cooling water passages. COPYRIGHT: (C)2006,JPO&NCIPI |
