Daimler also included a WHR system in their efficiency improvement strategy, with additional gains coming from directly improving engine efficiency. Gains from improved combustion via a predictive engine controller, as well as reductions in friction and pumping losses, increased BTE up to 47% before WHR. For their WHR system, Daimler chose an ORC with ethanol as the working fluid. Energy was recovered from the exhaust stream only and the system accounted for 1.3% of the absolute BTE gain, or a 2.8% relative improvement (compared with the 47% enhanced BTE). The WHR system drove an electrical generator which fed a hybrid electric drive system. Daimler’s next step will be to recover waste heat from the engine coolant and charge air cooler in addition to the engine exhaust. They estimate an additional 0.7% absolute gain in BTE, for a total of 2.0% absolute and 4.3% relative improvement in BTE. These results are significantly lower than what Cummins has achieved. Cummins does utilize the EGR system to recover heat from the higher temperature exhaust gases and may be further ahead in the development phase. Also, as mentioned before, Cummins may be recovering waste heat from additional sources such as engine coolant. One issue with these results is that each manufacturer participating in the SuperTruck program was allowed to choose the drive cycle over which they evaluated engine efficiency, and these drive cycles were not specified in the report. Therefore, it is difficult to compare the individual results without knowing what the conditions for evaluation were. However, the results are still useful in providing an indication of the current state of the art. The majority of the research on WHR systems focuses on applications for conventional gasoline or diesel engines. Srinivasan et al. [18] set out to model the potential of a WHR system applied to a diesel engine operating on Advanced Low Pilot Ignited Natural Gas (ALPING) combustion. The authors explain that ALPING injects pilot sprays of diesel early in the compression stroke to ignite a lean natural gas mixture. This method produces low temperature 14PDF Image | WASTE HEAT RECOVERY FROM A HIGH TEMPERATURE DIESEL ENGINE
