“…Waste cooking oil, which is cheaper than edible oils, is a good alternative for biodiesel production [8]. On the other hand, gas to liquid (GTL) as a synthetic alternative fuel is produced from natural gas via Low Temperature Fischer-Tropsch (LT-FT) synthesis, and it has been reported to reduce gaseous and particulate emissions [9] [10], and it comprises long-chain paraffin molecules and a bit poly-aromatic and sulphur [11]. GTL developed by Shell is sold as a blend in their V-Power diesel [12], and its blends with diesel are available in several European Countries [13] including Turkey.…”

The aim of this work was to compare the emission characteristics of a biodiesel derived from waste cooking sunflower oil and two fossil diesel fuels (ultra-low sulphur diesel and its type of containing gas-to-liquid). The tests were conducted on a direct-injection diesel engine-powered generator set, which is the type of generator applied in institutional facilities, under variable load and constant engine speed conditions. Experimental results showed that diesel containing gas-to-liquid and biodiesel reduced smoke opacity while NOx emissions were slightly higher for both fuels. An increase in fuel consumption was also observed for biodiesel compared with both fossil diesels. Unburned HC emissions were high for biodiesel, but overall level of CO emissions remained very low for all fuels tested.

“…Lower compression ratio will not only reduce NOx emissions by the lower in-cylinder temperature at the end of compression stroke, but will also reduce smoke emissions by better air utilization with increased chamber volume. [10][11][12][13][14]25 For the pre-injection, the spray penetration will increase with lower air density, resulting in the better distribution of the pilot burned gas in the chamber. Since FTD fuel has a higher cetane number, there is a potential to reduce the compression ratio without any deterioration of HC emissions and fuel consumption.…”

“…Most previous research has not discussed a method to improve both volumetric fuel consumption and exhaust emissions simultaneously with some engine modifications. [10][11][12] However, if engines are optimized to adapt to the distinctive specifications of FTD fuel, there could be a possibility to improve not only exhaust emissions, but also fuel consumption. 13,14 This study has two purposes for better understanding of the FTD fuel characteristics.…”

In recent years, paraffinic fuels have attracted attention because of their potential for reducing diesel exhaust emissions, mainly smoke or particulate matter emissions. One of the paraffinic fuels, a Fischer-Tropsch diesel fuel, was selected to demonstrate the lower exhaust emissions while improving fuel economy in this study. To examine the detailed effects of fuel specifications on diesel combustion and emissions, preliminarily tests for three Fischer-Tropsch fuels and a baseline diesel fuel were carried out with three diesel engines having different engine displacements. In addition, differences in combustion phenomena between Fischer-Tropsch fuels and the baseline diesel fuel were observed by means of a singlecylinder engine with optical access. From these findings, one of the tested engines was modified to improve both exhaust emissions and fuel consumption, simultaneously, dedicated to the use of neat Fischer-Tropsch fuels. The conversion efficiency of an oxides of nitrogen reduction catalyst has also been improved. The desirable properties of Fischer-Tropsch fuels for diesel combustion, namely high cetane number and absence of poly-aromatic hydrocarbon contents, have been fully utilized to enhance the conventional diesel combustion limits to show the possibility to achieve very low exhaust emissions with substantial improvement in fuel economy. The results of this study indicate not only the superior emission characteristics of the Fischer-Tropsch fuels, but also evidence that higher exhaust gas recirculation and lower excess air ratios will be a key concept of both engine and aftertreatment optimization for further fuel consumption improvement.

“…However, as the compositions of the fuels are different, the engine optimized to conventional EN590 fossil fuel is not able to take full advantage of the studied biofuel. Some recent biodiesel studies, e.g., refs and , and some F-T studies, e.g., refs and , have accounted for this fact mainly by adjusting engine parameters for the studied fuel. In the case of HVO, only a few studies , have adjusted engine parameters to better suit the HVO fuel.…”

Hydrotreated vegetable oil (HVO) diesel fuel is a promising biofuel candidate that can complement or substitute traditional diesel fuel in engines. It has been already reported that by changing the fuel from conventional EN590 diesel to HVO decreases exhaust emissions. However, as the fuels have certain chemical and physical differences, it is clear that the full advantage of HVO cannot be realized unless the engine is optimized for the new fuel. In this article, we studied how much exhaust emissions can be reduced by adjusting engine parameters for HVO. The results indicate that, with all the studied loads (50%, 75%, and 100%), particulate mass and NO(x) can both be reduced over 25% by engine parameter adjustments. Further, the emission reduction was even higher when the target for adjusting engine parameters was to exclusively reduce either particulates or NO(x). In addition to particulate mass, different indicators of particulate emissions were also compared. These indicators included filter smoke number (FSN), total particle number, total particle surface area, and geometric mean diameter of the emitted particle size distribution. As a result of this comparison, a linear correlation between FSN and total particulate surface area at low FSN region was found.
