Although this is not a centrally directed program • The SuperTruck projects incorporated a number of with a single-point authority over budgets and priorities, the vehicle power demand technologies that accounted for Partnership has made good progress since the NRC Phase 1 about 56 to 74 percent of the total fuel consumption and 2 reviews in improving communications, coordination reductions, with 26 to 44 percent coming from engine and collaboration among the partners, documenting most efficiency improvements (Chapter 8)

The fundamental diesel engine lyst on a DPF or others that have the potential to reduce the research program pursuing advanced technologies and volume, weight, and cost of the aftertreatment system should combustion processes and engine architectures to achieve be a part of the program to develop a 55 percent BTE engine. 55 percent BTE should continue to be a focus of the 21CTP

As a result, there is a need for 21CTP to as opportunities for integrated microelectrification of truck support R&D that will in time lead to commercially viable functions such as start/stop operation, idle reduction, waste hybrid drive technologies. heat recovery, engine starting, and accessory electrification.

Using the results available to date, about 26 to integration projects are possible, including these: 44 percent of the total vehicle fuel savings are due to engine efficiency improvements, while about 56 to 74 percent are • A regional haul SuperTruck, due to vehicle power demand reduction. In the Cummins– • A heavy-duty vocational SuperTruck (refuse, dump, Peterbilt project, 42 percent of fuel savings are due to the etc.)
