Based on the waste heat characteristic of the coolant and exhaust gas in heavy-duty diesel engine, the organic Rankine cycle (ORC) commercial product system is developed. The waste heat source is the engine jacket water and exhaust gas, and the jacket water is used as the heat source media which is used to heat the evaporator of the ORC system. The working fluid is the R245fa, and the plate-type condenser and evaporators are used. In the ORC system and 200-kW engine, the expander and generator can bring 14.5 kW electric energy in the normal working condition. The efficiency based on the first law of thermodynamics is 7.2 %; the completely generating efficiency is 6.25 %.
