Study on Effect of Synthetic Fuels with Different Properties on Heavy-Duty Diesel Engine Performance via Combustion Visualization Technique

Abstract

Paraffinic fuel has been received much attention and often studied its promising potential as a future low-carbon and cleaner emissions’ diesel alternative fuel by its less soot characteristics. However, the effects of each fuel property, which varies in a wide range along with other properties variation, on diesel combustion and emission characteristics has not been clearly revealed yet. That could make the preferrable fuel design difficult. This study investigated each fuel property effect on combustion and exhaust emission characteristics by adding several new fuels test to the previous study, and discussed the difference in combustion phenomena by utilizing combustion visualization technique.
