| 内容記述 | In heavy duty diesel engines, waste heat recovery systems are remarkable means for fuel consumption improvement. In this paper, Diesel-Rankine combined cycle (which is combined diesel cycle with Rankine cycle) is studied to clarify the quantitative potential of fuel consumption improvement with a high EGR rate and a high boosted diesel engine. The high EGR rate and high boosted diesel engine of a single cylinder research engine in New ACE reaches, brake specific fuel consumption (BSFC) of 193.3 g/kWh at full load (BMEP=2.0MPa), and its exhaust temperature reaches 370 deg. C. The exhaust gas temperature does not exceed 400deg.C in the high boosted diesel engine even at full load operating conditions because of a high excess air ratio. On the other hand, the quantity of exhaust gas is larger due to the high boosting. So, it is estimated that the thermal energy of exhaust gas is enough for recovery in the high boosted diesel engine, although exhaust gas temperature is not as high as an ordinary diesel engine. In the heat balance of the high boosted research diesel engine at medium engine speed, the exhaust loss is 38 % at full load. From this result, it is possible to recover the exhaust gas energy, when the engine is operated above medium load conditions. In this predictive study, water, methanol, toluene, HCFC-123,R134a and R245fa are compared as working fluid in Rankine cycle with superheating. As a result of this study, it is found that Diesel-Rankine combined cycle has a potential to improve BSFC from 2.6-3.0% at full load conditions. | |||||
