Study On Strengthening Combustion Of Engine And Reduction Of Exhaust Gas By Strong Discharge

The pollution of atmosphere has becoming more and more serious, the exhaust is one main reason to this problem, NOx can form photochemistry and acid rain. This paper is aim to reduce NOx and to strengthen combustion of engine by strong discharge at normal pressure, which is based on "the study on strengthening combustion of engine and reduction of exhaust gas with ion discharge" and "the method and application of ionizing gas with strong electric field ".Strong electric field can be formed in the plasma reactor with strong discharge. Electrons become non-equilibrium when they get energy in the field, after exciting , ionizing and decomposing the molecules of NO and NO2 are reduced.Excited the air in the engine entry by strong discharge technologies, there will be produced much high active particle such as OH- ,HO2 ,HO2 ,O2+,O2 and O3, and these high active particle can abbreviate the ignition delay, so by this way, the combustion can been strengthened and become more placid. The fuel consume can been depressed 0.9% to 2.5% to the changed load.The concentration of O2, the concentration of NOx, the flow of exhaust gas, the content of H2O are effected by reduced electric field, when the original concentration is fixed, the concentration of NOx has effect on the ratio of NOx-deduce. By adjusting the parameter of dielectric barrier discharge, such as E/n and Te , reduction rate of NOx can be controlled.
