This paper presents the performance, combustion and emission characteristics of a bio-oil obtained from Annona squamosa oil seed which is available across all over India. Pyrolysis was carried out between 450 ○ C and 550 ○ C under semi-batch type reactor for the production of Annona squamosa seed cake oil. The yield of the Annona squamosa seed cake oil was found to be about 40% at an optimum temperature of 500 ○ C. The pyrolysis oil was also characterized for its suitability of using it as an alternative fuel for internal combustion engines. The combustion, performance, and emission behaviour of the diesel engine operated with the different Annona squamosa seed cake oil-diesel blends were assessed and compared with those of diesel operation at different loads. The results indicated that the engine brake thermal efficiency was increased by about 27% for Annona squamosa seed cake oil-diesel blend of 20 percentage operation from no load to full load operation in comparison to diesel. The Brake specific energy consumption gets decreased by 20% for the B20 blend ratio compared to the diesel at full load condition. As the Annona squamosa seed cake oil -diesel blend ratio increases, the lower NO emission was found to be about 28% for B20, in comparison with diesel at full load condition. From the obtained results, it is suggested that the 20% Annona squamosa seed cake biooil blend can be considered as a potential candidate to be used as a fuel in compression ignition engines.

“…Some of the additives like alcoholic additives (solketal and ethanol) and antioxidant additives such as butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), tert-butylhydroquinone (TBHQ) and 2-ethylhexyl nitrate (EHN) [5,8,9] are used for reduction of emissions. In present study, B20 blend of mango seed oil methyl ester is used to investigate the effect of compression ratio and injection timing on performance, combustion and emission characteristics of a four stroke variable compression ratio (VCR) direct injection diesel engine for different compression ratios (CR) (14,16,18) and injection timings (IT) (21°, 23°, 25° before top dead centre (BTDC)).…”

“…Various modifications in engines such as exhaust gas recirculation (EGR), diesel oxidation catalyst (DOC), elective catalytic reduction (SCR) and diesel particulate filter (DPF) system have developed to minimize the pollutants. By varying various engine parameters like fuel injection timing [18,24], injection pressure, [6] compression ratio(VCR), [13][14][15][16][17][18][19][20][21] etc. and application of several techniques such as turbo charger, preheating, low heat rejection (LHR), and homogeneous charge compression ignition (HCCI) concept, etc [4,10,11], the performance, combustion, and emission characteristics of engines may be improved.…”

In this study, the effect of injection timing and compression ratio on performance, combustion and emission characteristics of a 4-stroke variable compression ratio (VCR) direct injection diesel engine is investigated for different compression ratios (CR) (14,16,18) and injection timings (IT) (21°, 23°, 25° before top dead centre (BTDC)) for mango seed oil methyl ester (MSME) biodiesel blend B20. The brake thermal efficiency (BTHE) is higher (28.86 %) and brake specific fuel consumption (BSFC) is lower (0.3 kg/kWh) at CR18 and IT 21° BTDC. Exhaust gas temperature (EGT) increases with brake power (BP) and showing lower value at higher CR and also at lower IT. The peak cylinder pressure attains at higher CR and advanced injection timing (25° BTDC). Net heat release rate is increasing with decreasing CR. At full load conditions, emissions of carbon monoxide (CO) ,carbon dioxide (CO 2 ) and hydro carbons (HC) are lower at lower IT and higher CR whereas nitrogen oxides (NO x ) is increasing with CR at all injection timings. The overall good performance and emission results show for CR18 and IT 21° BTDC.

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.
