“…Generally, bio‐oil blends have greater BSFC compared with F0 at standard engine operating conditions 25 . The higher consumption of bio‐oil is due to the low CV and high viscosity as compared with F0 1 . In general, biofuel has a greater BSFC compared with neat diesel at a standard compression ratio 37 .…”

Biofuel is a renewable fuel and can be used as a replacement for diesel. Pyrolysis oil can be derived from non‐edible de‐oiled seed cakes. This investigation focuses on the exergy investigation of a compression ignition (CI) engine to maximize the work exergy (availability) and minimize the destroyed exergy, powered by Aegle marmelos (AM) de‐oiled seed cake bio‐oil blends. A dual blend of diesel and AM pyrolysis oil was taken in ratios, F0 = 100 + 0, F5 = 95 + 5, F10 = 90 + 10, F15 = 85 + 15, and F20 = 80 + 20 and were tested on a constant speed CI engine at standard compression ratio. The investigational analysis exhibited that a high amount of oxygen content in AM pyrolysis oil blends increased the brake thermal efficiency and decreased the brake‐specific fuel consumption compared with diesel (F0). The owing exergy efficiency was obtained from the F20 blend (57.21%) at 100% load (W). Based on the investigation, considering availability and performance behavior of F5, F10, F15, and F20 blends were suggested as suitable biofuel alternatives to diesel.

“…Due to its ease and capability to analyze the outputs within the specified period, the GRA approach is generally employed in different engineering fields. 16 GRA is an MCDM technic that transforms the muti-attribute into a singleobjective model. In this method, all the responses were normalized between zero to one for ease of data interpretation.…”

The deficiency of fossil fuel resources, amplifying fuel price and its related environmental anxieties grasped great attention for finding an alternative fuel. Such alternative options can be fuels obtained from agricultural residues, plants, and wastes. The present research emphases on complex proportional assessment (COPRAS) and gray relational analysis (GRA) modeling of a diesel engine fuelled by Annona squamosa (AS) and Aegle marmelos (AM) co‐pyrolysis oil/diesel binary opus as an engine fuel to optimize the engine characteristics. Co‐pyrolysis oil is obtained from AS+AM feedstock at pyrolysis temperature of 500°C. To obtain engine data for training and testing the proposed COPRAS and GRA models were adopted for the engine control factors such as engine load (W) and compression ratio (CR) in a test engine rig through experimentation and hybrid optimization technics. From the engine output responses reveals that F2080 opus delivers an augmented brake thermal efficiency (22.01%) than diesel (21.56%) at peak load. Subsequently, F2080 fuel emits substantial lessening of CO (11.88%) and HC (5.64%) emissions as compared to diesel (F0). Based on the results, it is conclude that F2080 blend at CR of 17.5 and 100% load was delivered the greater engine distinctiveness through optimization outcomes and experimental evaluation compared to F0.

“…To the best of the author's knowledge, no momentous research has been reported, analyzing the effect of CR on operating characteristics of diesel engines powered with pyrolytic oil obtained from biomass. The characteristics of Bael pyrolysis oil, investigations on storage stability, its suitability for the operation of CI engine, optimization and exergy analysis were reported in the literature (Paramasivam et al, 2018;2019a;2020). From the experimental results, it was found that F20D is recommended as the greater fuel blend regarding the greater fuel stability and for better engine operating characteristics.…”

This work is focussed at studying the compression ratio (CR) effect on the operating characteristics of a diesel engine fuelled with diesel (80%) and pyrolytic oil (20%) blend, derived from Bael de oiled cake at standard conditions. Engine was operated at three CR’s namely 18:1 (higher), 17.5:1 (standard) and 16:1 (lower). For the blended fuel operation at full load, the brake thermal efficiency (BTE) improved by 5% and brake specific energy consumption (BSEC) diminished by 3% as the CR increased from 17.5 to 18. At high CR, the carbon monoxide (CO) and unburnt hydrocarbon (HC) were lowered by 58.3% and 38.5% respectively for blended fuel when compared to diesel at peak load. The nitrogen oxides emission (NOx) increased by 25.7% for blended fuel at peak load and CR of 18:1. On the whole the experimental results suggest that optimum performance of the engine can be attained at CR 18:1.
