“…A lower heating value was measured for each tested fuel as shown in Table 2. This fuel property is important as it could affect power output and torque [12,27]. The heating values of B30, B50 and B100 were 4%, 6% and 12% lower than that of the diesel fuel, respectively.…”

an experimental study was conducted to investigate the effect of high-ratio biodiesel and pure biodiesel on the emissions and performance of Euro4-compliant vehicles. The tested fuels were diesel fuel, biodiesel with a ratio of 30% by volume (B30), biodiesel with a ratio of 50% (B50) and pure biodiesel FAME (B100), while the tested vehicle is of the Euro4-compliant standard currently available in the Indonesian market. In this study, tests on emissions, performance and fuel economy were conducted based on the international standard of the UN ECE R83-05, adopted as UN ECE R-85 and UN ECE R-101 respectively. This study also investigated the effect of the carbon-to-hydrogen ratio on the carbon balance formula. Here, the paper proposed a modified R101 carbon balance formula to calculate the fuel economy for high-ratio and pure biodiesel fuels. The results showed that biodiesel had lower CO, HC and particulate emissions, while NOx emissions were higher compared to diesel fuel. However, pure biodiesel was within the limits imposed by the Euro4 emissions standard. Maximum power output with high-ratio biodiesel decreased by up to 10% with B100. The fuel economy of the B30, B50 and B100 biodiesels was lower than diesel fuel by 3%, 7% and 11%, respectively, based on the modified carbon balance formula for high-ratio biodiesel fuel.

“…The quaternary blends resulted in lower CO emissions than D100. The presence of sunflower biodiesel and alcohol provided more oxygen molecules for complete combustion (Modassir Khan et al 2021)- (Ghanei et al 2011). On the contrary, DBOProp20 resulted in the highest CO emission beyond 25% engine load.…”

“…Biodiesel offers enhanced lubricity as compared to diesel (Hu et al 2005). The sticking of the piston-cylinder set-up is avoided by using biodiesel due to the absence of aromatics in them (Modassir Khan et al 2021). However, certain disadvantages are also associated with biodiesel, such as it causing plugging of filters and fuel pipelines (Özener et al 2014).…”

The quaternary blends (diesel-biodiesel-vegetable oil-alcohol) offer enormous potential for reducing fossil fuel usage and mitigating air pollution caused by marine diesel engines. Biodiesel and alcohol are alternate fuels possessing high oxygen content, ensuring clean combustion. Vegetable oil is beneficial in saving diesel contribution and increasing engine lubrication. The objective of the present work was to reduce the dependency on conventional diesel and to come up with cleaner fuel that can also improve engine performance. This experimental work aims to lower exhaust emissions by fueling a single-cylinder, four-stroke direct-injection diesel engine with novel quaternary blends comprising diesel (50%), sunflower biodiesel (25%), sunflower oil (5%), and alcohol (20%). In order to develop cleaner fuel than diesel, different quaternary blends were prepared by varying the length of the carbon chain of alcohols in the blends, namely, DBOEth20, DBOProp20, DBOBut20, DBOHep20, and DBODec20. The performance emissions of quaternary blends were tested at varied engine loads from 5 Nm to 20 Nm (full load), while engine speed was fixed at 1800 rpm. The results indicate that DBOProp20 resulted in the lowest fuel consumption and highest thermal efficiency. DBOProp20 reduced CO2, NOx, and smoke emissions by 19.6%, 9.9%, and 85.7%, as compared to diesel.

“…When oil and its derivative fuels are burned, they cause the release of gases, which are described as greenhouse gases. Internal combustion engines are shown at the top of the emission sources of these GHG that cause global warming [1][2][3]. Diesel vehicles, commonly used in our society, are the most consumed of petroleum origin fuels.…”

Currently, many studies are being conducted to improve the emissions and combustion of diesel fuels of diesel vehicles. The majority of these studies consist of alcohol-derived fuels. Alcohol fuels are usually composed of butanol, methenol, and ethanol fuels. However, a high molecular alcohol such as iso-amyl with a high calorific value, which can be produced from sugar beet pulp, is the focus of more attention. Iso-amyl alcohol, chemical formula (CH3)2CH-CH2CH2-OH, oxygen rich, can mix with solvents such as ether, photography, pharmaceutical industry, milk oil quantity determination and synthesis, used in a colorless, foul-smelling liquid. In this study, the effects of the addition of iso-amyl alcohol to diesel fuel in order to reduce Diesel engine emissions were examined. For this purpose, 5%, 10%, and 20% iso-amyl alcohol were added to the diesel fuel. The resulting mixtures were subjected to full fuel analysis, unlike other studies. After that, the fuel mixtures in a Diesel engine at different engine speeds at full load (1400 rpm, 1700 rpm, 2000 rpm, 2300 rpm, 2600 rpm, 2900 rpm. and 3200 rpm) were tried. As a result of the experiments, it was determined that the contribution of iso-amyl alcohol caused a 1% -3% reduction in cylinder pressure, 12-20% in power, and 8-25% in torque. Furthermore, when examined in terms of exhaust gas emissions, it decreased in NOx emission by 1-10%, in smoke opacity by 9-36%, and in HC emission by 6-44%.
