Experimental investigations of oxidation stability of biodiesel produced from Prunus armeniaca oil (apricot oil) and effect of various antioxidants on stability, engine performance and emissions

It was found from experiments that CO emissions from B20/BHA4000 fuel are lower than diesel at full load while that of B20/PG4000 blend, CO emission was similar as diesel at full load. HC emission was found minimum for B20/BHA4000 among all four blends at full load. At low load NOx emission in B20 was lower and it increases with increase in engine load. NOx emission with B20/BHA4000 and B20/PG/4000 blend at full load was found to be minimum as compared to diesel.
