Diesel emissions, especially from heavy vehicles, have considerable negative impact on the quality of air in urban areas. The on-board reformulation of diesel fuel is a possible means of decreasing emissions. By converting the diesel fuel into hydrogen-rich gas, emissions from heavy engines may be decreased. This project will demonstrate the use of a plasma reformer to convert a substantial fraction of the diesel fuel. The challenge is to accomplish this without the substantial energy losses associated with partial oxidation reforming. A plasma reforming system, using exhaust gas recirculation, will be tested in Phase I. The system will be incorporated in an engine test stand (with a DDC 50 heavy duty engine), to evaluate the concept. NOx, CO, hydrocarbons, and particulate matter emissions will be monitored along with engine performance.
Commercial Applications and Other Benefits as described by the awardee: A successful method of controlling diesel emissions should have large commercial potential for the automobile industry.
