“…It was reported that butanol at 20% volume improved efficiency by 0.9% and lowered fuel consumption by 1.5% compared to neat punnai biodiesel in a stationary diesel engine. Rathinam et al 23 examined the effect of butanol in a diesel engine, and the results indicated that the addition of butanol to biodiesel is most effective to reduce all of the emission associated with the diesel engine. Balan et al 24 determined that by adding 10−20% (by volume) of octanol to mustard biodiesel lowered CO, HC, and smoke emissions significantly owing to enhancement in the oxygen content present in octanol, which lowers the emissions.…”

The enthusiasm for biofuels as feasible alternatives for use in diesel engines has significantly expanded on account of their spotless consuming nature in addition to fossil fuel independence. The present study utilizes two oxygenates, dimethyl carbonate (DMC) and n-butanol (n-B), derived from non-food-based lignocellulosic biomass in a blended form with transesterified oil extracted from waste sapota seeds to power a modern one-cylinder common rail direct injection (CRDi) diesel engine for any improvement in combustion, performance, and emission characteristics. Three test fuels, viz., B40%, B40% + DMC10%, and B40% + n-B10%, were prepared by splash blending, and the results were correlated with baseline diesel fuel. The experimental results indicate that accrual of oxygenates to sapota oil methyl ester has improved the combustion characteristics in comparison to diesel and B40% + n-B10%: the peak heat release rate (HRR) for B40% + DMC10% was 4.89 and 5.14% higher, respectively. The brake thermal efficiency (BTE) of an engine fueled with a B40% + DMC10% blend was better than that fueled with B40% + n-B10% but lower than that fueled with baseline diesel. The oxides of nitrogen (NO x ) emission were higher side when the engine was fueled with both oxygenated blends compared to diesel: B40% + DMC10% exhibits 6 and 2% higher values than diesel and B40% + n-B10%, respectively, at peak load conditions. Smoke opacity experienced a sharp reduction when fueled with a B40% + n-B10% blend; there was about 11.76, 19.60, and 23.52% reduction when fueled with diesel, B40%, and B40% + DMC%, respectively. Carbon monoxide for B40% + DMC10% was the lowest compared to diesel, B40%, and B40% + n-B10%, and there were about 21.59, 86.85, and 34.74% reduction in emissions, respectively. Hydrocarbon emission for B40% + DMC10% was the lowest compared to diesel, B40%, and B40% + n-B10%, and there were about 8.62, 27.58, and 17.24% reduction in emissions. Reformulation of diesel with DMC, n-butanol, and sapota oil methyl ester renders a chance to decrease emissions and use renewable fuel in diesel engines.

“…Diesel generates higher HC emissions than diesel. Diesel is denser, creating cylinder wall wetting and leading to layers where the combustion flame is extinguished before complete combustion than with MSBD HC emission lowers by 0.24 g/KWh with H 2 induction to MSBD.…”

This study aims to examine the ignition pattern of CI engines run by nonedible mango seed biodiesel (MSBD). This work is also aimed to improve the ignition pattern of diesel engines by inducing hydrogen as a dual fuel in the intake manifold at various mass flow rates of 5 and 10 L per minute (lpm). Various parameters were calculated with varying intake hydrogen rates with MSBD and compared with diesel. Results concluded that the hydrogen supply at 10 lpm improved peak pressure by 3.22 bar, heat release rate (HRR) by 5.47 J/°C A, and brake thermal efficiency (BTE) by 3.4% of MSBD. Further, hydrogen supply also reduced overall HC by 0.36 g/ kWh, CO by 3.9 g/kWh, and smoke emission by 3.8 Bosch smoke unit (BSU) at all brake mean effective pressures (BMEPs) from neat MSBD with a 3.3 g/kWh increase in NO. Further, this research work reveals that hydrogen addition at 10 lpm with MSBD shall improve the ignition patterns of a diesel engine.

“…Further DTBP and 1-Pentadecanol blends produce more O 2 during combustion which agitates the NO formation. Different studies (Saravanan et al 2017;Devarajan et al 2020;Rathinam et al 2019;Balan et al 2018) proved that the O 2 -rich fuels always end up with higher NO emission.…”

“…Adding 10% of n-1-Pentadecanol to KBD/D blends lowered the emission by 3.3%, where 10% addition of DTBP lowered the same by 4.9%. The significant reduction is due to cetane number (high), viscosity (less), O 2 availability (high) of DTBP/ KBD/1-DEC/D blends which ends up in better combustion and lower HC (Sudalaimuthu et al 2018;Rathinam et al 2019). Devarajan et al (2019a, b) and Devarajan (2018) employed different additives (DTBP and DMC) and lowered the HO emission than BD.…”

This study examines the impact of the oxygenated additives namely DTBP (Di-Tetra-Butyl-Phenol) and 1-Pentadecanol (1-DEC) on emissions, combustion and performance patterns of Karanja biodiesel/diesel blends. Two additives were selected as ignition improver owing to their improved physicochemical properties. The additives were mixed at 10% volume with the equal blends of diesel and biodiesel. Experimental results revealed that by adding additives and biodiesel to diesel found no phase separation. HRR and peak pressure were highest for diesel and least for KBD/D blends. However, blending the additives enhanced its HRR and peak pressure. Addition of additives lowered the harmful emissions significantly with a slight increase in NO emissions to the KBD/D blends. In addition, a noteworthy increase in performance aspects was observed for KBD/D blends by adding DTBP and 1-Pentadecanol.
