Abstract：To achieve efficient recovery of exhaust heat from turbocharged diesel engines,a steam injection waste heat recovery system is proposed.Based on a turbocharged diesel engine test bench,a steam injection waste heat recovery system is designed and built,and the effect of the steam injected system on diesel engine performance is studied experimentally.The experimental results show that steam injection can effectively improve the boost pressure under low and medium speed conditions,and the maximum specific fuel consumption of diesel engines can be improved by 5.8 g/(kW·h).Under high-speed operating conditions,injected steam further increases the exhaust back pressure of the diesel engine,which makes it impossible to improve the fuel efficiency of the diesel engine.To improve the effectiveness of the steam injection waste heat recovery system,it is necessary to further optimize the matching of the diesel engine turbocharging system.
