Utilizing KOH as catalyst has increased HC emissions 54,58% and CO emissions 18,10% in spite of decreasing CO2 emissions 15,45%, NOx emissions 28,45% on average comparing to NaOH. 93% of CO2 emissions of pollutants in the atmosphere, 57% of HC, 39% of NOx and 1% of SO2 is vehicle sourced. Most important polluter are particulate matter emissions (PM) and NOx for diesel engines. It has been observed that use of cotton seed methyl ester as engine fuel is decreased to NO emission in our study.eninfo:eu-repo/semantics/closedAccessCotton seed methyl ester-dieselPotassium hydroxideEngine emissionArticle28211671174N/AWOS:000297087600064N/A
