EXPERIMENTAL INVESTIGATION OF THE PERFORMANCE OF A FOUR-STROKE CI ENGINE UTILIZING DIESEL, LIZA OIL, AND BUTYLATED HYDROXYTOLUENE BLENDS

Abstract

Amidst the depletion of natural resources, the surge in petroleum fuel costs and the impending scarcity of transportation options have prompted a quest for viable alternatives. One promising avenue is the exploration of vegetable oils, such as Liza oil, blended with Butylated Hydroxytoluene (BHT) at a 2% concentration. To optimize the economics of biodiesel production, researchers are delving into continuous transesterification and glycerol recovery from by-products. In this study, the performance and emissions of distinct blends of diesel and Liza oil with the additive (B10, B20, B30, B40, and B50) are systematically evaluated under various loads and at constant speeds. Encouragingly, the Liza oil blend outperformed diesel, with B30 and B40 blends exhibiting the highest mechanical and brake thermal efficiency. Notably, the B10 and B30 blends demonstrate the lowest and highest brake-specific fuel consumption, respectively. Furthermore, the B20 Liza oil biodiesel displays reduced hydrocarbon emissions compared to conventional diesel fuel. These findings shed light on the promising potential of Liza oil blends as a favorable alternative in the landscape of sustainable fuels.
