New Technologies for Reduction of Automobile Exhaust Emissions
EMSL Project ID
3589
Abstract
The goal of the research is to evaluate the effectiveness of a non-thermal plasma in conjunction with catalytic materials to mediate exhaust gas emissions from diesel fueled light duty compression ignition direct injection (CIDI) internal combustion engines. The project is focussed on efficiently reducing the NOx emissions with a secondary goal being the simultaneous oxidation of hydrocarbons and particulate. While preliminary studies indicate that plasma-catalyst systems can reduce NOx emissions in simulated diesel exhaust, improvements in the efficiency and design of the plasma reactor systems as well as in the efficiency of the catalyst materials is necessary for vehicle applications. The ultimate objective of the program is to develop a plasma assisted catalyst system that is capable of reducing at least 90% of nitrogen oxides in the exhaust gas of compression ignition direct injection diesel fueled light duty vehicles while realizing at most a 5% fuel penalty as a result of the energy required to operate the plasma-catalyst reactor. Research will focus on five general areas: catalyst development, reaction mechanism identification, plasma-particulate interactions, prototype reactor development, and engine testing.Project Details
