the output of a heat engine such as a WHR system, either the heat input can be increased or the temperature of the source can be raised. For this analysis, the temperature of the sink was set to 25°C (i.e., 298.15 K) for all points to ensure consistency in the evaluation of exergy. The temperature of the heat source was taken to be the average temperature of the coolant inside the engine or the average exhaust temperature in the manifold. The heat loss to the exhaust was found by taking the difference in the enthalpy for each exhaust gas component (CO, CO2, H2O, and N2) at the average exhaust temperature leaving the engine and at 25°C. Figure 6-3 shows the waste heat and total exergy for the coolant and exhaust over the measured coolant temperature range for 3100 rpm at 18 N-m and 24 N-m of engine torque. This figure demonstrates that, even though the coolant waste heat flow decreases for each load point as the coolant temperature rises, the total exergy generally increases due to higher coolant and exhaust temperatures. Despite the decrease in coolant waste heat between 10% and 27%, the coolant exergy increases between 20% and 45% from 90°C to 150°C coolant temperature. For example, at the 18 N-m (56% load), the coolant waste heat drops from 5.60±0.40 kW to 4.23±0.30 kW, whereas the coolant exergy rises from 1.00±0.08 kW to 1.25±0.10 kW for the same interval. Simultaneously, the exhaust waste heat rises from 5.92±0.26 kW to 6.37±0.30 kW, which is reflected in a temperature increase of the exhaust gases: from 373.9°C at 90°C to 429.2°C at 150°C (Figure 6- 4). Thus, the total exergy from the engine increases from 4.19±0.13 kW to 5.10±0.17 kW over the interval for a 22% increase. Above 150°C, coolant exergy declines for the 18 N-m torque point, which may be a result of the combustion chamber leakage. At 24 N-m of torque (74% load), the increase in exergy is even more substantial. Though coolant waste heat drops from 7.23±0.52 kW to 5.05±0.38 kW from 90°C to 200°C coolant temperature, the coolant exergy rises from 1.28±0.09 kW to 1.86±0.14 kW, a 45% increase. The exhaust heat rises from 8.45±0.27 kW to 10.05±0.35 139PDF Image | WASTE HEAT RECOVERY FROM A HIGH TEMPERATURE DIESEL ENGINE
