Statistical analysis of engine fueled with two identical lower aromatic biofuel blends at various injection pressure

Abstract

ABSTRACT This work aims to find an alternative source of energy in the engine revolution with more efficiency concerning performance characteristics, emission behavior and combustion characteristics than traditional diesel fuel. In this present work, the following composition is obtained by blending Orange Peel Oil (OPO) and Lemon Peel Oil (LPO) at 20%, traditional diesel fuel at 80% (Blend 1) & OPO and LPO at 12.5%, traditional diesel at 75% (Blend 2) and Use a single-cylinder direct-injection diesel engine to determine the optimal composition across all dimensions. Compared with diesel, there is a noticeable decrease in emissions such as CO, UHC, and smoke and an increase in NOx emission, as well as a significant improvement in thermal efficiency or energy efficiency. BTE was increased 3% while using blend 2 and 2% while using blend 1 at peak load condition when weighted against to traditional diesel fuel. BSFC decreases on both blends when compared to diesel. But NOx is higher when compared to diesel, hence it can be reduced by using additives like BHT, 2EHN and PD at 1.2%, 0.8% and 98% of mixing proportions and run it on a single cylinder engine under varied pressure at 300 bar, 450 bar and 600 bar respectively. The Taguchi optimization is opted to find the best blend in all aspects. It is found that the L16 orthogonal array was used to for this investigation. The NOx has been reduced nearly by 10% when compared to LPO and OPO blends and it gives more efficient results both in efficiency and reduced toxic emissions.
