This paper focuses on the evaluation of the fuel properties of Fischer–Tropsch diesel blends with conventional diesel. Incorporating this advanced fuel into conventional diesel production will enable the use of waste materials and non-food materials as resources, while contributing to a reduction in dependence on crude oil. To evaluate the suitability of using Fischer–Tropsch diesel, cetane number, cetane index, CFPP, density, flash point, heat of combustion, lubricity, viscosity, distillation curve, and fuel composition ratios using multidimensional GC × GC-TOFMS for different blends were measured. It was found that the fuel properties of the blended fuel are comparable to conventional diesel and even outperform conventional fuel in some parameters. All measurements were performed according to current standards, thus ensuring the repeatability of measurements for other research groups or the private sector.

“…The shorter DoC arising from the oxygen content results in a shorter residence time at high temperature, thus this may reduce the NOx formation. Since the NOx-PM trade-off is minimized, extreme high EGR rates can be used to further reduce the NOx emission without the risk of high PM emission (Parravicini et al, 2021).…”

Oxymethylen Ether (OME) is a promising alternative fuel for diesel engines. It can be produced sustainably, and its combustion is clean and efficient. This study investigates the effects of different OME3-5 mixtures on emissions and combustion. The measurements were done on a four-cylinder common rail commercial diesel engine equipped with an exhaust gas recirculation system (EGR). Five different blends of OME3-5 and B7 diesel were applied with 0, 7, 15, 25 and 45 vol% OME3-5 content at four loads. The NOx–PM trade-off was investigated at 11 EGR rates for each mixture at each load. Increasing OME3-5 mixing ratio reduced the PM emission, improved the NOx–PM trade-off, and increased the brake thermal efficiency. The maximum achieved PM emission reduction was 86.8% for high loads. However, NOx emission increased, and also low heat capacity and viscosity can be a problem for real applications

“…The primary disadvantage of HVO is the absence of Oxygen (O 2 ) and that it is expensive compared to other biodiesels. From the results of previous studies, it is evident that when HVO is used at high loads, NO X and PM are reduced by up to 50% compared to standard diesel fuel [48][49][50].…”

Comparative Study of Combustion, Performance and Emission Characteristics of Hydrotreated Vegetable Oil–Biobutanol Fuel Blends and Diesel Fuel on a CI Engine

et al. 2022

This article is a study of Hydrotreated Vegetable Oil and Butanol Fuel blends, which are mixed in three different proportions (HVOB5, HVOB10 and HVOB20), and the comparison of their combustion (in-cylinder pressure, pressure rise and ROHR), performance (fuel consumption, BSFC and BTE) and emission (CO2, NOX, HC and Smoke) characteristics with those of fossil diesel fuel. In the wake of finding an alternative fuel that requires little to zero modifications to the existing IC engines, it is necessary to account for the necessity of matching the efficiency of conventional fuels as well as greatly reducing its exhaust emissions. As a result of transesterification, HVO is found to have better stability and higher CN compared to other biofuels. It is termed a “renewable diesel” due to its ability to reduce emissions while maintaining efficiency. HVO as a fuel has higher cost efficiency, and for a more stable oxygen content in the fuel, an alcohol substitute is needed. Butanol, which has a considerable advantage over other alcohols due to its higher density, viscosity and CN, is selected. HVOB5 and HVOB10 are found to match diesel fuel in terms of fuel consumption while having a ~1% lesser efficiency. In terms of emissions, all the fuel mixtures including HVO100 are found to have ~4–5% lesser CO2, ~10–15% lesser NOX and a ~25–45% reduction in smoke levels.
