“…The reduction of NO x emissions is an advantage of green diesel over biodiesel and petroleum diesel and it was verified experimentally also in other communications [226,227,231,[239][240][241][242][243]. However, some ambiguity exists since other communications have reported unchanged or increased green diesel NO x emissions [232,233,236,237,244]. Finally, most communications [228,232,[235][236][237]239,[241][242][243] claim that green diesel reduces the emission of the solid particulates by up to 45%, in agreement to the Neste report [216] mentioned previously.…”

The present investigation provides an overview of the current technology related to the green diesel, from the classification and chemistry of the available biomass feedstocks to the possible production technologies and up to the final fuel properties and their effect in modern compression ignition internal combustion engines. Various biomass feedstocks are reviewed paying attention to their specific impact on the production of green diesel. Then, the most prominent production technologies are presented such as the hydro-processing of triglycerides, the upgrading of sugars and starches into C15–C18 saturated hydrocarbons, the upgrading of bio-oil derived by the pyrolysis of lignocellulosic materials and the “Biomass-to-Liquid” (BTL) technology which combines the production of syngas (H2 and CO) from the gasification of biomass with the production of synthetic green diesel through the Fischer-Tropsch process. For each of these technologies the involved chemistry is discussed and the necessary operation conditions for the maximum production yield and the best possible fuel properties are reviewed. Also, the relevant research for appropriate catalysts and catalyst supports is briefly presented. The fuel properties of green diesel are then discussed in comparison to the European and US Standards, to petroleum diesel and Fatty Acid Methyl Esters (FAME) and, finally their effect on the compression ignition engines are analyzed. The analysis concludes that green diesel is an excellent fuel for combustion engines with remarkable properties and significantly lower emissions.

“…Same results were also reported by Sugiyama et al (2011), who mentioned that HVO can reduce HC and soot emissions due to high cetane number and zero aromatic content, but NO x emissions were similar with market diesel fuel. Pflaum et al (2010), after conducting engine and vehicle testing with HVO, did not notice appreciable reduction in NO x emissions.…”

“…Moreover, the lower density and the lower viscosity of HVO accelerate the mixture formation, reducing also the ignition delay. Pflaum et al (2010), have found that a reduction of up to 50% in both CO and HC emissions can be achieved with HVO as compared to conventional diesel. Similar results were also observed by Kousoulidou et al (2014) in a light-duty diesel engine running with HVO fuel.…”

Evaluation of a Hydrotreated Vegetable Oil (HVO) and Effects on Emissions of a Passenger Car Diesel Engine

In the coming years, the application of paraffinic biofuels, such as Hydrotreated Vegetable Oils (HVO), in the transportation sector is expected to increase. However, as the composition of HVO is different compared to conventional diesel, the engine optimized for conventional fuel cannot take full advantage of the HVO beneficial properties. Suitable adjustment of a number of engine parameters, if not complete engine re-calibration, will enable the full exploitation of such fuels' potential for lower exhaust emissions and reduced fuel consumption. In the present work, the emission characteristics of HVO fuel in a light-duty Euro 5 diesel engine have been studied, under steady-state operation, as well as during the New European Driving Cycle (NEDC). The study was expanded to the investigation of exhaust emissions under modified Main Injection Timing (MIT) and EGR rate. The NEXBTL fuel, produced by Neste, was considered in the study and was compared with conventional market diesel. Emissions of nitric oxides (NO x ), soot, carbon monoxide (CO), carbon dioxide (CO 2 ), and hydrocarbons (HC) were studied. At default MIT and EGR settings the use of HVO resulted in a significant reduction of all regulated emissions. In addition, it was observed that the adjustment of MIT and EGR can enhance the exploitation of HVO potential for emissions reduction, highlighting the differences with the conventional diesel fuel.

“…Most literature shows significant reduction in CO, HC, PM and smoke emissions with the use of the HRD against petro-diesel but the reported results on NOx emissions are ambiguous. A majority of researchers [16,22,23,25,[27][28][29] showed that HRD reduces NOx, whereas some are uncertain about NOx emission and tried to correlate it with driving conditions [20,30,31], and a few have reported that NOx increases with the use of HRD [24,26] due to its higher CN and heating value. It was shown that HRD leads to higher in-cylinder pressure and heat release rate as compared to diesel, which results in slightly higher NOx.…”
