The exhaust emissions data were taken in the exhaust pipe at a distance of 1 m from the engine. In this study, canola methyl ester (CME) was used as alternative diesel fuels. Rawcanola oil (RCO) was esterified using the transesterification system developed at the Technical Education
Faculty, Automotive Laboratory of Firat University. RCO and methanol were mixed in certain ratios and kept at 60 C for 9 h and then converted into methyl ester.
