Thirty unconventional gaseous substances in Fischer–Tropsch process diesel/methanol-mixed fuel with different methanol blending ratios were measured and classified for diesel engine pollutant discharge. The measurement results showed high concentrations of several unconventional pollutants, including propylene, 1,3 butadiene, acrolein, benzene, toluene, ethylbenzene, and xylene, accounting for approximately 83% of the total concentration. The methanol blending ratio was increased from 0 to 15%, the amounts of unconventional pollutants such as olefins, alkanes, and aromatic hydrocarbons were decreased by 38.4%, 27.7%, and 23.7%, respectively, and the amounts of aldehydes and ketones were increased by 31.2%. The amounts of unconventional pollutants such as 1,3 butadiene, n-hexane, and benzene were decreased by 36.6%, 28.8%, and 29.2%, and the amount of acrolein was increased by 28.7%. At maximum torque, aromatic hydrocarbon emissions were reduced by 23.8%, aldehyde and ketone emissions were reduced by 44.8%, olefin emissions were increased by 142.8%, and alkane emissions were reduced by 14.5%; compared to maximum torque conditions, olefins under calibration category emissions were increased by 41.2%, alkane emissions were increased by 8.8%, aromatic hydrocarbon emissions were increased by 9.5%, and aldehyde and ketone emissions were increased by 25%.

费-托工艺柴油/甲醇混合燃料中有30种非常规气态物质，其甲醇混合比不同，并对其进行了排放分类。测量结果显示高浓度的几种非常规污染物，包括丙烯，1,3丁二烯，丙烯醛，苯，甲苯，乙苯和二甲苯，约占总浓度的83％。甲醇的混合比例从0％增加到15％，烯烃，烷烃和芳烃等非常规污染物的含量分别减少了38.4％，27.7％和23.7％，醛和酮的含量增加了减少了31.2％。1,3丁二烯，正己烷和苯等非常规污染物的数量减少了36.6％，28.8％和29.2％，丙烯醛含量增加了28.7％。在最大扭矩下，芳烃排放减少了23.8％，醛和酮排放减少了44.8％，烯烃排放增加了142.8％，烷烃排放减少了14.5％。与最大扭矩条件相比，校准类别下的烯烃排放量增加了41.2％，烷烃排放量增加了8.8％，芳烃排放量增加了9.5％，醛和酮排放量增加了25％。
