“…It is clear that this 2nd generation biofuel causes significant reduction in soot emissions in the whole engine operating range of up to 75%, a finding that comes in agreement with previous research Sugiyama et al, 2011). The reason is that HVO is an exclusively paraffinic fuel with higher H/C ratio, no aromatics, sulfur and other mineral impurities that are responsible for soot formation (Rimkus et al, 2015).…”

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.

“…for market diesel to 143 mg for HVO. As it was already mentioned, HVO is a paraffinic fuel with shorter molecular chain and higher H/C ratio, with almost zero aromatic, sulfur and other mineral impurities content, which enhance PM formation, factors that all contribute to lower soot emissions (Rimkus et al, 2015).…”

“…A traditional electromagnetic conversion system uses a pure electromagnetic structure: the coil is wound on the iron core (copper or aluminium) with current, forming a closed magnetic field of a permanent magnet and a permanent magnet‐driven piston, denouncing the piston work by electromagnetic piston between a permanent magnet and an electromagnetic conversion system, and permanent magnet piston works through electromagnetic repulsion between permanent magnet piston and electromagnetic conversion system. The current in the coil is controlled by the drive control system, and the electromagnetic coil is used to finish the dynamic adjustment so that it changes the electromagnetic force of the piston according to the working requirements, and then the electromagnetic force is controlled [2].…”

“…The use of bioenergy as energy derived from biofuels in the world permanently increases [ 1 , 2 ]. Biomass-based fuels as renewable organic source of bioenergy have advantages (e.g., no harmful carbon dioxide emissions, reduction of dependency on fossil fuels, and versatility) and some disadvantages (e.g., requiring more land, relative ineffectiveness when compared to gasoline, and problematic supply chain) as well [ 3 – 6 ]. One of important sources of biomass-based fuel is Jatropha curcas L. [ 7 – 10 ].…”

One of important sources of biomass-based fuel is Jatropha curcas L. Great attention is paid to the biofuel produced from the oil extracted from the Jatropha curcas L. seeds. A mechanised extraction is the most efficient and feasible method for oil extraction for small-scale farmers but there is a need to extract oil in more efficient manner which would increase the labour productivity, decrease production costs, and increase benefits of small-scale farmers. On the other hand innovators should be aware that further machines development is possible only when applying the systematic approach and design methodology in all stages of engineering design. Systematic approach in this case means that designers and development engineers rigorously apply scientific knowledge, integrate different constraints and user priorities, carefully plan product and activities, and systematically solve technical problems. This paper therefore deals with the complex approach to design specification determining that can bring new innovative concepts to design of mechanical machines for oil extraction. The presented case study as the main part of the paper is focused on new concept of screw of machine mechanically extracting oil from Jatropha curcas L. seeds.
