Evaluation of MWCNTs as Nanoadditives in a Propanol-Biodiesel-Diesel Mixture on Compression Ignition Engine Characteristics.

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
Cleaner alternatives to internal combustion engines are essential for reducing pollution emissions while maintaining performance. In this study, a ternary blend of diesel, biodiesel, and propanol (80:10:10 by volume) was prepared and enriched with multiwalled carbon nanotubes (MWCNTs) at concentrations of 40, 60, and 80 ppm to evaluate its combustion, performance, and emission in a monocylinder diesel engine. Compared to diesel fuel, the ternary blends with MWCNTs demonstrated an increase of up to 6.73% in the net heat release rate and an average decrease of up to 14.74% in cylinder pressure. Engine performance improved with a rise in the brake thermal efficiency up to 11.79% on average, while the brake-specific fuel consumption decreased by up to an average of 6.04%. Emission analysis indicated substantial reductions in carbon dioxide (up to 18.72%) and nitrogen oxides (up to 42.39%), whereas unburned hydrocarbons increased by an average of 26.66%. These results indicate that the synergistic interaction among biodiesel oxygen content, propanol volatility, and the catalytic/thermal conductivity properties of MWCNTs enables improved combustion efficiency while mitigating carbon dioxide and nitrogen oxides. This study provides new insight into the role of carbon-based nanomaterials in enhancing oxygenated ternary diesel blends and highlights their potential to support cleaner and more efficient compression ignition engine operation.
