PURPOSE:To make effective utilization of waste heat possible by cooling high temperature air from a supercharger at first with cooling water of a specific temperature and then cooling with water of a specific temperature lower than the first cooling thereby making utilization of waste heat of both engine coolant and air conditioner coolant. CONSTITUTION:High temperature air of about 130 deg.C from a supercharger 2 is supplied through two stages of air-supply collers 3a and 3b to an engine 1. The upstream side air-supply cooler 3a is cooled with cooling water of 80 deg.C-100 deg.C which can utilize coolant water discharged from a cooling system of the engine. The downstream side air-supply cooler 3b is then cooled with water of 30 deg.C-35 deg.C which can utilize coolant water discharged after cooling an air conditioner.
