Ignition analysis of diesel engine propelled with neat biodiesel containing nanoparticles

Abstract

ABSTRACT In this work, biochar was added with grape seed biodiesel at different concentrations of 25 and 50 ppm to facilitate the ignition behavior of a diesel engine. Results conclude that the nano-biochar addition at 50 ppm reduced hydrocarbon by 2.2%, carbon monoxide by 2.8% and smoke emission by 3.5% at all load from neat biodiesel with a 3.4% increase in NO. This work also revealed that the biochar improved combustion patterns such as peak pressure (1.2 bar), heat rate (4.1 J/CºA), cumulative heat rate (0.08 kJ), and efficiency (2.4%) of biodiesel.
