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 caused by exhaust emissions and are liable for many health issues further more. Emissions of diesel exhaust might lead to cancer, irritate the eyes, affects the nose, throat and lungs. Biodiesel is an eco-friendly and typical alternative fuel which is produced from vegetable oils through transesterification technique. Biodiesel has its own several advantages than the conventional diesel says decreased in carbon monoxide (CO), unburnt hydrocarbon (HC) and particle matter (PM) emissions, and having fuel properties which are similar to conventional diesel for its easier use in diesel engines. The outcomes demonstrated that the production of lesser CO and HC emission using biodiesel. Nevertheless, a minor increment in NOx emission was noticed for mahua oil methyl ester blends. Brake Specific Fuel Consumption (BSFC) for methyl ester blends was raised as compared to diesel. The combustion analysis exhibited a significant rise in combustion pressure and heat release rate with smaller ignition delay and extended combustion period. From the investigation, it could be said that the effects of mahua oil methyl esters and its blends on diesel engine when compared to conventional diesel ultimately minimizes the health effects of biodiesel exhaust exposure.
