Abstract:Based on the engine waste heat recovery using organic Rankine cycle (ORC), a vehicle energy-supplying system was proposed to satisfy energy demand of vehicle in every season. Based on a typical vehicle engine, the vehicle energy-supplying system based on the waste heat recovery was analyzed. The simulation results showed that reducing the log mean temperature difference (LMTD) in the first evaporator, decreasing the environment temperature and enhancing the vehicle speed are three effective methods to increase the turbine power output and fuel saving rate. In winter, the maximal fuel saving rate is achieved to satisfy the heat and power requirements of the vehicles. In spring /autumn, it could save much fuel consumption, and the power demand of vehicle could be satisfied. In summer, the minimal fuel saving rate and thermal efficiency of the bottom ORC are achieved. The maximum value of turbine power output and fuel saving rate are 14.7 kW and 0.23 respectively under the operation conditions in this paper. © 2019 The Authors. Published by Elsevier Ltd.
