MWCNTs’ Effects on the Performance & Emission Analysis of VCR Diesel Engines Fuelled by Blends of Diesel and Neem Biodiesel

Abstract

The present research shows how a diesel engine’s emission characteristics were affected by the mixture of functional multi-walled carbon nanotubes (MWCNTs) to diesel-biodiesel fuel. The blends of B0, B10, and B20 biodiesel were combined with the MWCNT nanoparticles. Using ultrasonication, the MWCNT nanoparticles were distributed into B0, B10, and B20 at concentrations of 0 and 25 ppm. Engine testing was done with the engine running at 1500 rpm and 16 CR continuously. We looked into the characteristics of performance and emissions, such as BTE and CO emission. The outcomes demonstrated that, in comparison to B0, adding MWCNTs to B25 reduced emissions and enhance performance. The findings of this study may open the door to the development of diesel engines that use mixes of biodiesel with nano additives. In order to replace crude oil in engines, the majority of countries nowadays are searching for alternative fuels. Examples of these include renewable energy sources like solar power, biodiesel, wind energy, edible and non-edible oils, natural gas, alcohol, and hydrogen fuel. Different ratios of biodiesel and different amounts of CNT nanoparticles were combined to create test fuel samples. To achieve practicality in the real world, dispersion was achieved without the requirement for a nanoparticle stabilizer. Using ultrasonication, the diesel and biodiesel were combined and sheared at a high speed to distribute the nanoparticles evenly throughout the mixtures
