NOx emission in biodiesel using waste cooking oil of high acid value was investigated. The
synthesized nano catalysts were characterized using FTIR, XRD, DLS, BET and SEM. The
maximum yield of biodiesel reached 91% under optimized reaction conditions of 4% catalyst
(w/w of oil), molar ratio of alcohol to oil of 10: 1 for 4 hours at 65 C. Engine performance and
emission characteristics of fame acid methyl esters investigated in a four stroke diesel …
