大型ディーゼルエンジンにおける排熱回生の可能性について

抄録

The available energy of exhaust gas at the exhaust turbine outlet and EGR gas at the cooler inlet has a big potential to improve brake thermal efficiency (BTE). The improvement in BTE by taking Waste Heat Recovery measure into consideration was predicted 9.6 points at full load operating condition, if available energy of exhaust gas in the high boosted diesel engine is ideally converted into effective work without any losses. However, conversion efficiency of a combined cycle is generally still low. So, the improvement in BTE by the combined cycle was estimated 1.5 points even at full load operating condition.
