Effect of DMC blend ratio on emission characteristics for diesel engine generator fueled with DMC/diesel blended fuel

Energy shortage and environmental problems are two dominant subjects. The diesel engine is well-known for its high thermal efficiency but severe emission problems. For the urgent fossil fuel resources, substantial surrogate fuel, dimethyl carbonate (DMC) attracting attention oxygen content. Its application in engines has won increasing focus. However, it difficult to directly with DMC due low cetane number latent vaporization heat. In this study, DMC/diesel blend 5%, 10%, 15% by volume prepared investigate characteristics. Since combustion process strongly influenced addition of boiling point boosts atomization liquid mixture, emissions hydrocarbons particulate matter significantly reduced addiction especially on high-load conditions. Also, nitrogen oxide slight reduction scope balancing NOx PM exists.
