Performance Analysis of the Organic Rankine Cycle (ORC) System under Engine Various Operating Conditions

Kai Yang and Hongguang Zhang
Abstract—Though experiments, variation of a diesel engine exhaust energy is studied, a set of ORC system is designed and set up. The variation of running performance of an ORC (organic Rankine cycle) system under engine varying working conditions is analyzed, the effects of evaporating pressure on the ORC system is discussed, the improvement extent of engine thermal efficiency, brake specific fuel consumption (BSFC) after the engine is coupled with a set of an ORC system is studied. The research shows that, when evaporating pressure being 3MPa, engine speed being 2200r/min and engine torque being 1200N·m separately, the net power output of the ORC system, engine thermal efficiency increasing ratio (ETEIR), and the Improvement ratio of BSFC all hits the maximum values, being 22.41kW, 8.085%, 7.423% respectively.

Index Terms—Vehicle diesel engine, waste heat recovery, organic Rangine cycle, various operating conditions.
