Impact of Oxygenated Additives on Performance Characteristics of Methyl Ester in IC Engine

Abstract

In this present work, the impact of blending n-butyl alcohol, a next generation biofuel with jatropha biodiesel on the performance of a diesel engine are examined. Tests were performed on a constant speed compression ignition engine using n-butyl alcohol / jatropha biodiesel blends. N-butyl alcohol was added to jatropha biodiesel by 10, 20 and 30% by volume. Performance parameters namely break thermal efficiency (BTE), Brake specific fuel consumption (BSFC) and Exhaust gas temperature (EGT) were analyzed in this work. It was experimentally found that by adding n-butyl alcohol to neat jatropha biodiesel, significant reduction in viscosity was observed. In addition, break thermal efficiency was increased by 0.8 % due to improved atomization of the blends. Further, brake specific fuel and exhaust gas temperature was further reduced due to lower viscosity and improved combustion rate with addition of n-butyl alcohol to jatropha biodiesel.

Combustion, Performance, and Emission Study of a Research Diesel Engine Fueled with Palm Oil Biodiesel and Its Additive

“…Many investigations have proven that adding additives (metal-based) in powder form to BD facilitates as a catalyst in boosting the engine combustion and performance and improves its fuel properties. − Nanoadditives alter the chemical composition of BD and enhance the oxidation characteristics. Nanoadditives also aid the engine combustion and performance characteristics of fuel . Venu and Madhavan conducted a research work on adding metal oxides [at different parts per million (ppm)] to neat BD in a compression-ignition (CI) engine.…”

Performance and Emission Analysis of Diesel Engine Using Thermal Barrier Coating and Addition of Cerium Oxide Nanoparticles to Palm Biodiesel

“…The implications of wear through corrosion, thermal aspects and mechanical loads, leads to power loss and engine seizing with a loads of hazardous emissions to the environment. Without engine or oil modification major issues, such as injector sticking and blocking which prevent engine operation, occurs when using pure vegetable oils in diesel engine (Yuvarajan et al, 2016a). Improvement of lubricate conditions on engine components, leads to the frictional losses in engines.…”
