A MATERIAL DROP OF EXHAUST GAS AND PROMOTION OF COMBUSTION

摘要

A composition for promoting combustion and reducing soot and smoke is provided to improve power output of the internal-combustion engine and reduce harmful gas contained in exhaust gases by improving combustion efficiency of an internal-combustion engine. A composition for promoting combustion and reducing soot and smoke is prepared by blending 60 to 90 wt.% of pozzolana comprising 68.9 wt.% of silicon dioxide(SiO2), 17.6 wt.% of alumina(Al2O3), 5.74 wt.% of iron oxide(Fe2O3), 1.54 wt.% of magnesium oxide(MgO), 3.55 wt.% of potassium oxide(K2O), 1.66 wt.% of sodium oxide(Na2O), 0.36 wt.% of calcium oxide(CaO), 0.62 wt.% of titanium dioxide(TiO2) and 0.03 wt.% of manganese oxide(MnO), 2 to 12 wt.% of tourmaline comprising 2.53 wt.% of sodium(Na), 2.30 wt.% of lithium(Li), 21.58 wt.% of iron(Fe), 11.43 wt.% of magnesium(Mg), 17.86 wt.% of aluminum(Al), 3.51 wt.% of boron(B), 17.69 wt.% of silicon(Si), 22.70 wt.% of oxygen(O) and 0.40 wt.% of hydrogen(H), and 8 to 28 wt.% of anion composite mineral comprising 40.7 wt.% of calcium(Ca), 0.4 wt.% of manganese(Mn), 8.7 wt.% of magnesium(Mg), 0.8 wt.% of iron(Fe), 14.63 wt.% of aluminum(Al), 33.4 wt.% of silicon(Si) and 1.37 wt.% of sulfur(S) using water, drying the mixture to completely remove water from the mixture, and baking the dried mixture in a kiln with a temperature of 1000 to 1300 deg.C for 30 minutes to 2 hours.
