Performance, combustion, emission and optimization characteristics of biodiesel-n-butanol blends enriched with Ni
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In the pursuit of sustainable and clean energy, biofuels and nanofuels are increasingly investigated as practical solutions to improve diesel engine efficiency and emission characteristics. This study evaluates the effects of Nickel (III) oxide nanoparticles added to biodiesel (B20) and biodiesel-n-butanol (B20But10) blends on combustion, engine performance, emissions, and optimization using a single-cylinder, four-stroke, water-cooled, direct injection diesel engine. Experiments were conducted at multiple engine loads and nanoparticle concentrations ranging from 0 to 100 ppm. At full load and 100 ppm Ni₂O₃, peak in-cylinder pressure increased to 55.86 bar for B20 and 55.45 bar for B20But10, while maximum heat release rates reached 29.45 and 30.02 J/°CA, indicating enhanced premixed combustion behavior. Brake thermal efficiency increased to 24.89% for B20 and 24.94% for B20But10, accompanied by reductions in brake specific fuel consumption to 0.309 and 0.333 kg/kWh, respectively. Emission results showed reductions of 13-28% in HC, 8-43% in smoke opacity, and 12-21% in NO
