“…Biodiesel is a cleaner fuel due to its low pollutants emission to the environment. Pure biodiesel has lower emissions of greenhouse gases, such as carbon monoxide, carbon dioxide and sulphur oxides (Chuah et al, 2015a). Biodiesel has affirmative combustion properties which make it a better replacement in diesel engine without any alteration and it can be utilised on its own or blended with fossil diesel in any volumetric ratio (Mostafaei et al, 2015).…”

“…Chuah et al (2015) reported that more than 720°C exhaust gas temperature may cause permanent damage to a compression ignition engine. In the present work, the variation of exhaust gas temperatures is similar for all fuel blends and it increases with brake power as shown in Fig.…”

“…As the major load of the automobile sector is shared by the compression ignition engine, several researchers have been attracted to work in the area of alternative or supplementary fuels for CI engine (Ng et al 2010a). During the last few decades, researchers are working on to trim down the pollution level from the compression ignition engines (Chuah et al 2015). Biodiesel has been chosen by many researchers from the perspective of sustainability, economic and environment friendly behaviour (Ng et al 2010b;Sadeghinezhad et al 2013).…”

A numerical simulation has been carried out in this study to evaluate the effect of alcohol addition to the blends of diesel and palm stearin biodiesel on the performance, combustion and emission of a diesel engine. The commercial software Diesel-RK has been used in this study to simulate a single-cylinder, naturally aspirated, direct injection, four-stroke diesel engine. The simulated results have been validated against experimental observation for the base fuel diesel. The effects of two alcohols, namely ethanol and methanol have been separately investigated and compared. The results indicate that although the brakespecific fuel consumption is slightly increased, the other performance characteristics and the entire combustion and emission parameters are improved with alcohol addition to diesel-biodiesel blends. The instantaneous heat release rate, ignition delay and oxides of nitrogen emission are found to be more with methanol than with ethanol. The diesel-biodiesel blend also shows better combustion and emission characteristics than that of diesel except oxides of nitrogen emission.

“…These superior properties of biodiesel improve combustion efficiency and reduce the pollutant emissions in diesel engine. While biodiesel provide significant reductions in hydrocarbons (HC), carbon monoxide (CO), and soot emissions, it causes a small increase in nitrogen oxide (NO x ) emissions (Chuah et al 2015).…”

In this experimental study, biodiesel production from free fatty acids of soybean oil and the effects of its blends with alcohol-diesel on diesel engine performance and exhaust emissions were studied. Crude glycerine was neutralized to produce the free fatty acids. Methyl alcohol was reacted with the free fatty acids in the presence of acid catalyst to form biodiesel. Biodiesel, diesel, and alcohols were mixed at different volumetric ratios, and the properties of each blend were determined. The blends and diesel were tested in a single cylinder direct injection diesel engine at full-load conditions. In conclusion, torque and power characteristics of blends were found similar to those of diesel. Break specific fuel consumption of the blends slightly increased depending on lower heating values. CO and smoke emissions decreased up to 34.52 and 39.30 %, respectively. Although NO x emissions increased with B50, it showed a downward trend with alcohol-containing blends.
