Investigation on effects of the exhaust emission characteristics of diesel engine fuelled with mahua oil methyl esters and its blends with diesel

Abstract

Diesel engines are deliberately known for environmental pollution causedby exhaust emissions and are liable for many health issues further more.Emissions of diesel exhaust might lead to cancer, irritate the eyes, affectsthe nose, throat and lungs. Biodiesel is an eco-friendly and typicalalternative fuel which is produced from vegetable oils throughtransesterification technique. Biodiesel has its own several advantages thanthe conventional diesel says decreased in carbon monoxide (CO), unburnthydrocarbon (HC) and particle matter (PM) emissions, and having fuelproperties which are similar to conventional diesel for its easier use indiesel engines. The outcomes demonstrated that the production of lesserCO and HC emission using biodiesel. Nevertheless, a minor increment inNOx emission was noticed for mahua oil methyl ester blends. BrakeSpecific Fuel Consumption (BSFC) for methyl ester blends was raised ascompared to diesel. The combustion analysis exhibited a significant rise incombustion pressure and heat release rate with smaller ignition delay andextended combustion period. From the investigation, it could be said thatthe effects of mahua oil methyl esters and its blends on diesel engine whencompared to conventional diesel ultimately minimizes the health effects ofbiodiesel exhaust exposure.
