Modeling and simulation analysis on parallel hybrid air-fuel vehicle

Pinglu CHEN, Xiaoli YU, Xianghong NIE, Yidong FANG

Frontiers in Energy 2010, Volume 4, Issue 4, Pages 553-559 doi: 10.1007/s11708-010-0008-y

Abstract: Based on the vehicle simulation software ADVISOR, the model of a parallel air-fuel hybrid vehicle was established, and the modeling of an air powered engine (APE), heat exchanger, braking air tank and control strategy were discussed in detail. Using the vehicle model, a hybrid vehicle refitted from a traditional diesel car was analyzed. The results show that for the New European Driving Cycle (NEDC), the Urban Dynamometer Driving Schedule (UDDS) and the Highway Fuel Economy Test (HWFET) driving cycle, the total reductions in fossil fuel consumption of the hybrid vehicle were 48.29%, 48.51% and 22.07%, respectively, and the emissions could be decreased greatly compared with the traditional diesel car, while the compressed air consumptions of the hybrid vehicle were 97.366, 85.292 and 56.358 kg/100 km, respectively. Using the diesel equivalent as the indicator of fuel economy, the hybrid vehicle could improve the fuel economy by 14.71% and 16.75% for the NEDC and the UDDS driving cycles and decrease by 5.04% for the HWFET driving cycle compared with the traditional car. The simulation model and analysis in this paper could act as the theoretical basis and research platform in optimizing the key components and control strategy of hybrid air-fuel vehicles.

Analysis of a 1 kW organic Rankine cycle using a scroll expander for engine coolant and exhaust heat recovery

Yiji LU, Anthony Paul ROSKILLY, Long JIANG, Longfei CHEN, Xiaoli YU

Frontiers in Energy 2017, Volume 11, Issue 4, Pages 527-534 doi: 10.1007/s11708-017-0516-0

Abstract: The development of engine waste heat recovery technologies attracts ever increasing interests due to the rising strict policy requirements and environmental concerns. This paper presented the study of engine coolant and exhaust heat recovery using organic Rankine cycle (ORC). Eight working fluids were selected to evaluate and compare the performance of the integrated waste heat recovery system. Rather than the conventional engine ORC system mainly focusing on the utilization of exhaust energy, this work proposed to fully use the engine coolant energy by changing the designed parameters of the ORC system. The case study selected a small engine as the heat source to drive the ORC system using a scroll expander for power production. The evaluation results suggest that under the engine rated condition, the solution to fully recover the engine coolant energy can achieve a higher power generation performance than that of the conventional engine ORC system. The results suggest that adding a recuperator to the ORC system can potentially improve the system performance when the working fluids are dry and the overall dumped heat demand of the system can be reduced by 12% under optimal conditions. When the ORC evaporating and condensing temperature are respectively set at 85°C and 30°C, the integrated engine waste heat recovery system can improve the overall system efficiency by 9.3% with R600, R600a or -Pentane as the working fluid.
