| Abstract:The effect of diesel/methanol/n-butanol blend fuels on emission performance was studied with a single-cylinder 4-stroke diesel engine. The volume ratio of alcohol in the blend fuels was 5.09%, 9.82%, 14.66%, and 19.35%, and the volume ratio of n butanol was 2.67%, 4.81%, 7.13% and 9.27%, respectively. The results of the experiments indicate that the use of blend fuels will improve the fuel consumption and thermal efficiency by 0.18% to 4.08% and 0.28% to 3.54% coupled to the reduction of output power and torque by 0.75% to 11.37% and 1.42% to 25.03% and hence CO, NO, NOx and PM2.5 emissions by 2.76% to 45.15%, 3.55% to 29.21%, 3.55% to 20.03% and 7.09% to 48.94%, but the addition of alcohol fuels to diesel will cause formaldehyde, acetaldehyde and volatile organic compounds to increase by 2.78% to 60.53%, 5.15% to 63.81% and 3.75% to 45.49%, respectively. In summary, use of blend fuels of diesel and alcohol allows to mitigate PM2.5 emissions while reducing NOx emissions. |
