Abstract


With car ownership in China continues to increase vehicle fuel consumption and pollutant emissions are rising ; especially in vehicle emissions , the serious pollution of the atmospheric environment . In order to alleviate the energy shortage in the form and reduce the pollution of the atmosphere , in the last decade , the engine research workers have done a lot of work . However , due to various reasons , the research is not very significant . The article on the basis of the previous low temperature plasma technology is proposed to deal with vehicle emission pollution , the purpose of this paper is to study this novel technology as the current governance of automobile exhaust pollution . Firstly, the development of low-temperature plasma and Research , proposed the use of low-temperature plasma clean automobile exhaust program ; Second, the mechanism of low-temperature plasma generated by high voltage pulse discharge , by analyzing the plasma removal gasoline pollutant chemical reaction process, and the the plasma purification mechanism of gasoline engine exhaust gas , to purify gasoline engine exhaust to establish a theoretical basis for the low-temperature plasma ; Finally, we designed according to the actual situation of the line - the barrel plasma ; then, through a large number of the study and analysis of the research results , the design matches the high - voltage pulse power systems with the purifier ; parameters matching the best of the power and gas flow rates required in order to obtain the line - Canister plasma purifier , we carried out at room temperature and under atmospheric pressure the simulation test of standard gas , through the analysis of the experimental results , we get several best matching parameters of the power in the purification of the exhaust emissions of the gasoline engine . On this basis , we simulated vehicle exhaust NO N 2 O 2 system to establish a dynamic model , model NO reaction kinetics curves and experimental the data are compared to verify the reasonableness of the reaction mechanism . The article also used the kinetic model , the kinetics of the reaction of the rest of the components in the simulated exhaust also analyzed and forecast .
