The purpose of this study is to require countermeasures for alternative energy of diesel combustion engines, which has a serious impact on air pollution when using the quantitative limit of petroleum-based energy and transportation energy. This study attempted to study the usefulness of the oxygen component in fuel as a measure to reduce exhaust emissions from diesel engines used in reality. Dimethoxy methane (DMM), which contains about 42% oxygen in itself, was mixed with diesel and applied to a diesel engine. As a result of the study, it was confirmed that as the oxygen content in the fuel increased, smoke was greatly reduced and NOx increased.
