The depletion of natural resources coupled with the alarming increase of pollution level is the driving force to use diesel in an environmentally benevolent manner. Research done till now is mainly focused upon the utilization of lower alcohols and information on higher alcohol blend is limited. The present study aims to investigate the effect of using a ternary blend of diesel, biodiesel, and decanol on a diesel engine. Tests were performed using decanol blended with biodiesel and diesel. The concentration of ternary blends were 10%, 15%, 20%, 30%, and 40% of decanol by volume while the diesel concentration was maintained to be 50% throughout. The study revealed that among the ternary blend, brake thermal efficiency increases with increase in the concentration of decanol. The brake specific fuel, and energy consumption decrease with an increase in alcohol content. Thus 40% decanol blend shows the least brake specific fuel consumption. NOx emission increased with the increase of alcohol concentration, whereas the emission levels of CO, HC, and smoke opacity decreased. Peak pressure is also found to be highest for 40% decanol blend and least for 10% decanol blend. With the addition of decanol content in the ternary blend, heat release rate is found to be increased whereas the cumulative heat release rate is observed to be reduced during the end phase of combustion. The study concluded that 40% blend of decanol, biodiesel and diesel can optimize engine performance and emission without performing any modifications in the CI engine. © 2018 Elsevier Ltd

<a href="https://www.sciencedirect.com/topics/engineering/diesel-engines">Diesel engines</a> occupy a crucial position in automobile industry due to their high thermal efficiency and high power to weight ratio. However, they lag behind in controlling air polluting components coming out of the <a href="https://www.sciencedirect.com/topics/engineering/exhaust-systems-engine">engine exhaust</a>. Therefore, diesel consumption should be analyzed for future energy consumption and this can be primarily controlled by the <a href="https://www.sciencedirect.com/topics/engineering/petroleum-fuel">petroleum fuel</a> substitution techniques for existing diesel engines, which include <a href="https://www.sciencedirect.com/topics/engineering/biodiesel">biodiesel</a>, alcohol-diesel emulsions and diesel water emulsions. Among them the diesel water emulsion is found to be most suitable fuel due to reduction in <a href="https://www.sciencedirect.com/topics/engineering/particulate-matter">particulate matter</a> and NOx emission, besides that it also improves the brake thermal efficiency. But the major problem associated with emulsions is the <a href="https://www.sciencedirect.com/topics/engineering/ignition-delay">ignition delay</a>, since this is responsible for the power and torque loss. A reduction in NOx emission was observed due to reduction in <a href="https://www.sciencedirect.com/topics/engineering/combustion-chamber">combustion chamber</a> temperature as the water concentration increases. However the side effect of emulsified diesel is a reduction in power which can be compensated by <a href="https://www.sciencedirect.com/topics/engineering/oxygen-enrichment">oxygen enrichment</a>. The present study investigates the effects of oxygen concentration on the performance characteristics of a diesel engine when the intake air is enriched to 27% of oxygen and fueled by 10% of water diesel emulsion. It was found that the brake thermal efficiency was enhanced, combustion characteristics improved and there is also a reduction in HC emissions.
