An Experimental Study Using Canola Oil Biodiesel to Examine the Properties of a Diesel Engine with Decanol as an Additive

Abstract

A naturally beneficial use of diesel is primarily threatened by the depletion of natural resources and the alarming rise in pollution levels. The majority of research conducted to date has been on the use of lower alcohols; information regarding a higher alcohol mix in canola oil biodiesel is less abundant. This study investigates the effects of adding a ternary mixture of diesel, biodiesel, and decanol as an additive to a CI engine. Diesel and biodiesel were combined with decanol to conduct tests. While the diesel concentration was maintained at 50% throughout, the decanol mixing concentrations were 10%, 20%, and 30% by volume. According to the study, as decanol concentration rises, brake specific fuel consumption falls and brake thermal efficiency rises. At full load, BTE values of 32.24% and 31.68% for pure diesel and D50COME20DEC30, respectively, were noted. The ternary blend D50COME20DEC30 BSFC was 12.89% and 20.63% lower than those of COME100 and D50COME50. Although the total heat release rate is seen to be reduced during the end phase of ignition, heat release rate is observed to increase with the expansion of decanol content in the ternary mix. NOx emissions for D50COME50 and for 10%, 20%, and 30% of decanol in the ternary blend were 1869 PPM, 1838 PPM, 1819 PPM, and 1810 PPM. Therefore, in order to increase engine performance and emissions without altering the CI engine, the present examination recommends a 30% blend of decanol, 20% biodiesel, and 50% diesel.
