Spray and Combustion Characteristics of CTL-Diesel Fuel Blends in a Constant-Volume Combustion Chamber. [PDF]

ACS Omega, 2023
Coal-to-liquid (CTL) fuel is considered a promising alternative fuel for diesel engine applications in China owing to its excellent fuel properties. However, little research on the spray and combustion processes of CTL fuel has been scarce. Therefore, in this study, the spray and combustion characteristics of diesel fuel blends with different CTL fuel ...
