TL;DR: In this article, the performance, emission, and combustion characteristics of vegetable oil esters with varying saturated and unsaturated fatty acid composition tested in a stationary direct injection compression ignition engine were investigated.
Abstract: The present work is concerned with the performance, emission, and combustion characteristics of vegetable oil esters with varying saturated and unsaturated fatty acid composition tested in a stationary direct injection compression ignition engine. Saturated fatty acids (SFAs) are long-chain carboxylic acids that usually have between 12 and 24 carbon atoms and have no double bonds. Unsaturated fatty acids resemble SFAs, except that the chain has one or more double bonds. SFAs have all the hydrogen that the carbon atom can hold and therefore have no double bond between the carbon atoms. The biodiesels were derived from Pongamia, Ricebran, Sunflower, and Palm oil, respectively. The results show that Pongamia biodiesel gives a higher brake thermal efficiency (33.36% when compared to diesel, which has 32.57%) slightly higher Oxides of Nitrogen [NOX] and reduced carbon monoxide (CO), unburnt hydrocarbon (UHC), and smoke emissions when compared to diesel and other biodiesels. The cetane number for Pongamia oil, ...
TL;DR: In this article, the effects of fatty acid methyl esters proportion on combustion and emission characteristics of a biodiesel fueled diesel engine in terms of heat release rate, cylinder pressure, indicated power and formation of NOx emission were investigated.
TL;DR: In this paper, waste cooking oil biodiesel was mixed with titanium dioxide (TiO2), a metal-based nano particle, and n-butanol (C4H9OH) along with euro diesel to examine their effects on diesel engines.
TL;DR: In this article, the authors compared three different blended (20/80 by vol.) biodiesels of rice bran, neem, and cottonseed oils with varying degree of unsaturation.
TL;DR: In this paper, a skeletal four-component biodiesel combustion mechanism comprising methyl decenoate, methyl-5-decenate, n -decane and methyl linoleate is proposed.
TL;DR: In this paper, the influence of binary and ternary blends of diesel and biodiesel on performance, emission and combustion characteristics of a diesel power generator was analyzed on a single-cylinder, four-stroke, naturally aspirated, and direct-injection diesel engine at four engine loads with a constant engine speed of 3000 rpm.
Abstract: The objective of the present study is to scrutinize the influence of a binary blend of diesel–safflower oil biodiesel and ternary blends of diesel–biodiesel–pentanol on performance, emission and combustion characteristics of a diesel power generator. The test fuels were prepared on volume basis by splash blending and named as follows: B20, B20P5, B20P10, B20P15, and B20P20. The tests were carried out on a single-cylinder, four-stroke, naturally aspirated, and direct-injection diesel engine at four engine loads with a constant engine speed of 3000 rpm. According to the results, ternary blends vaguely reduced BTE while increased BSFC up to 13.90% as compared to diesel. In addition, an increase in pentanol concentration has a considerable effect on the decrease in NOX emissions. It is noted that the addition of pentanol to diesel–biodiesel blend caused to lower emissions (CO, HC, and smoke), whereas CO2 emission increased noticeably thanks to the more complete combustion due to the excess oxygen content. Reviewing combustion analysis results, pentanol addition led to decrease heat release rate and lower ignition delay up to 15% blend ratio compared to diesel. Based on the present study, pentanol can be evaluated as a promising type of higher alcohol for the compression ignition engines in the near future.
