Abstract
This paper investigates the potential of a fluid driven waste heat recovery cycle to improve the efficiency of a long haul Heavy Duty Diesel Engine (HDDE) operating at Euro 6 engine out NOx emissions levels. Performance and heat rejection data for a 10-litre HDDE were derived from experimental measurements on an advanced 2-litre single cylinder research engine. A detailed selection study with 15 ranking criteria's was undertaken, identifying non-ozone-depleting Hydro-Chloro-Carbon as the optimal class of working fluids. Results indicated a potential of 2.4% and 3% point brake thermal efficiency improvement using thermal energy recovered from the Exhaust Gas Recirculation (EGR) cooler alone and from combined EGR cooler and post turbine exhaust recovery configurations respectively.
