Removal of emission gas COx, NOx and SOx from automobile using non-thermal plasma

Abstract

Non-polluted plasma muffler prototype has done in fuel engine vehicle. Pilot scale improvement has done by integrating reduction system into vehicle muffler from previous position outside the muffler. High voltage that used to develop plasma condition comes from 12V34Ah accumulator which connected with electronic equipment and it can be able to develop voltage up to 20kV. Exhaust gases reduction ability has done by varying engine rotation. Plasma muffler appearance in vehicle doesn’t change outside dimension of its original muffler and it reactor placement in muffler has a function to change resonator chamber function and make this muffler still fulfil muffler standardization with more performance in reducing exhaust gases (COx, NOx, HC). Optimal reduction level made at 2200 rpm for COx is 86.52%, for CO is 88.93%, for HC is 97.34% and for NOx at 4600 rpm is 76,19%. The residue formed in the muffler has been tested with FTIR. Of all possible feeds, the compound constituent of the NOx reduction product is ammonium carbonate ((NH4) 2CO3), ammonium sulphite ((NH4)2SO3), and also ammonium sulphate ((NH4) 2SO4).
