چکیده    The present study uses three generations of biodiesels and studies their effects on physical properties and exhaust gases. they are comprised of palmaria palmate oil (third generation), eucheuma spinosum oil (third generation), eucheuma cottonii oil (third generation), common wormwood oil (second generation), marjoram oil (second generation), peganum harmala oil (second generation), zingiber officinale oil (first generation), anethum graveolens oil (first generation), and cacao bean oil (first generation). results show that first-generation oils gain a higher level of calorific value around 41.16 mj/kg than other generations. the longest carbon chain is observed by the first generation with higher unsaturated fatty acids than other generations (94.11 %). the first generation gains a higher level of density around 882 kg/m3 than other generations. also, the first generation gains a higher level of flash point around 193 ˚c than other generations. the third generation gains a high level of cetane number at about 69, compared to other generations. the first generation gains a minimum level of cloud and pour point around -3 ˚c and -2 ˚c compared to other generations. moreover, the third generation gains the lowest level of viscosity about 2.51 cst compared to the first generation. the third generation gains the lowest level of nox around 371 ppm compared to other generations. finally, the third generation gains the lowest level of soot, co, and hc around 0.47 vol. %, 0.018 vol. %, and 4.82 ppm, compared to other generations.
