Regulations on exhaust emissions from diesel engines have become hardness, because they have a great influence on the environment. PM concentration can reduce by improve combustion, but weight concentration of PM is decreased, it may increase number concentration of PM. Therefore, in this study, we are reduced about number concentration of PM by gas mixture fuel and corona discharge into the intake air. Corona discharge is generated ozone at the same time of discharge, and takes in ozone (OH radical) into the intake air. Gas mixture fuel can be premixed fuel and air to expand at the same time of combustion, so we can be expected improvement of combustion.
