PURPOSE:To enable various units to be cooled without using any special cooling systems while effectively utilizing exhaust heat by providing heat exchangers for fuel valve cooling water, exhaust valve cooling water, supercharger lubricating oil, etc. in an intake path leading to the supercharger. CONSTITUTION:In the intake side intake path 14 of a supercharger 1 used for a marine engine or the like are disposed a heat exchanger 10 for emitting heat of cooling water for a fuel injection valve 4, a heat exchanger 9 for emitting heat of cooling water for an exhaust valve 3 and a heat exchanger 8 for cooling lubricating oil of the supercharger 1. Thus, cooling apparatus for these heat exchangers do not need to be particularly provided, and heat of auxiliaries can be utilized for preheating new charge to improve the efficiency. |
