In relation to the fact that barium compounds have a remarkable effect on the reduction of smoke level, the effect of barium compounds on soot formation is investigated in the combustion in diesel engine. Barium compound particles are either suspended in the inlet air or mixed with fuels.
When barium compound particles are suspended in the inlet air, soot formation is suppressed less than its mixed with fuels. From the differences of size and form of soot and carbon particles between with and without barium compounds, it is suggested that barium compounds affect in the coagulation process of carbon particles, resulting in the reduction of smoke in the exhaust gas.
