In this paper, the amount of heat wasted from different parts of a 12-liter compression ignition engine and the recoverable heat from these parts were investigated. Then, two-stage configuration of organic Rankine cycle was introduced for simultaneous heat recovery from exhaust gases and coolant. Finally, parameters such as hybrid generated power, engine thermal efficiency, and brake specific fuel consumption were studied at different engine speeds under full engine load. By adopting this method, 35 kW hybrid power can be generated consequently, causing 9.5% reduction in brake specific fuel consumption.
