エンジンシステムにおける排熱回収

抄録

For reducing the global energy use and carbon dioxide emission, it is very important to improve the efficiency of widely used motor vehicles. Because it is difficult for battery electric vehicles and fuel cell vehicles to replace a large part of the currently used conventional vehicles in short term, to improve the efficiencies of engine powered vehicles is more practical and effective. Recovering waste heats from engine can be a effective technique for improving the vehicle efficiency. This article explains the characteristics of engine heat balance and overviews the prospect of waste heat recovering technologies in engine systems.
