The Vehicle Technologies Office funds early-stage, high-risk research to develop technology upon which industry can implement innovative transportation energy technologies that increase efficiency, decrease cost, and expand use of domestic energy sources, such as liquefied petroleum gas (LPG). To improve the viability of medium and heavy-duty vehicles the LPG engine efficiency must be closer to that of diesel. This work addresses fundamental limitations to achieve diesel-like efficiencies in heavy duty on-road LPG engines. The primary goal of this research is to achieve diesel-like efficiencies in heavy duty on-road LPG engines, focusing on the Cummins 15-liter engine platform (baseline diesel efficiency of 44% at peak torque). That goal has been achieved, though more work is needed to facilitate practical implementation of the developed technologies.
