AbstractThe increase of the environment pollution, together with the instable price of crude oil led in the last years to a renewed focus on biofuels. As the demand in the transport sector is continuously increasing, and taking into account the benefits of biofuels, it is expected that the market demand for biofuels to be increased in the near future. In this context, it will be interesting to investigate if new types of biofuels could be used as mixtures with other fuels for internal combustion engines. The aim of this paper is the study of density and viscosity variation with composition and temperature for ternary mixtures biodiesel + diesel fuel + bioalcohol. Experimental densities and viscosities data for ternary blends diesel fuel+biodiesel +isopropyl alcohol/1-butyl alcohol are presented, and some empirical models proposed to predict these properties for binary systems diesel fuel+biodiesel are evaluated for the proposed ternary blends.

Over the decades, more attention has been paid to emissions from the means of transport and the use of different fuels and combustion fuels for the operation of internal combustion engines than on fuel consumption. This, in turn, enables research into products that are said to reduce fuel consumption. The report summarizes four studies of fuel-related innovation products. The studies covered by this report are conducted with diesel fuel and usually contain diesel fuel and three additives for it. Manufacturers of additives are based on already existing studies showing a 10-30% reduction in fuel consumption. Comparative experimental studies related to the use of commercially available diesel fuel with and without the use of additives have been performed in laboratory conditions. The studies were carried out on a stationary diesel engine СМД-17КН equipped with brake КИ1368В. Repeated results were recorded, but they did not confirm the significant positive effect of additives on specific fuel consumption. In some cases, the factors affecting errors in this type of research on the effectiveness of fuel additives for commercial purposes are considered. The reasons for the positive effects of such use of additives in certain engine operating modes are also clarified.

The worldwide consumption of fossil hydrocarbons in the road transport sector in 2020 corresponded to roughly half of the overall consumption. However, biofuels have been discreetly contributing to mitigate gaseous emissions and participating in sustainable development, and thus leading to the extending of the commercial utilization of internal combustion engines. In this scenario, the present work aims at exploring the effects of alternative fuels containing a blend of 15% ethanol and 35% biodiesel with a 50% fossil diesel (E15D50B35) or 50% Fischer–Tropsch (F-T) diesel (E15FTD50B35) on the engine combustion, exhaust emissions (CO, HC, and NOx), particulate emissions characteristics as well as the performance of an aftertreatment system of a common rail diesel engine. It was found that one of the blends (E15FTD50B35) showed more than 30% reduction in PM concentration number, more than 25% reduction in mean particle size, and more than 85% reduction in total PM mass with respect to conventional diesel fuel. Additionally, it was found that the E15FTD50B35 blend reduces gaseous emissions of total hydrocarbons (THC) by more than 25% and NO by 3.8%. The oxidation catalyst was effective in carbonaceous emissions reduction, despite the catalyst light-off being slightly delayed in comparison to diesel fuel blends.

Fossil fuels are exhausting quickly because of incremental utilization rate due to increase population and essential comforts on par with civilization. In this connection, the conventional fuels especially petrol and diesel for internal combustion engines, are getting exhausted at an alarming rate. In order to plan for survival of technology in future it is necessary to plan for alternate fuels. Further, these fossil fuels cause serious environmental problems as they release toxic gases into the atmosphere at high temperatures and concentrations. The predicted global energy consumption is increasing at faster rate. In view of this and many other related issues, these fuels will have to be replaced completely or partially by less harmful alternative, eco-friendly and renewable source fuels for the internal combustion engines. Hence, throughout the world, lot of research work is in progress pertaining to suitability and feasibility of alternative fuels. Biodiesel is one of the promising sources of energy to mitigate both the serious problems of the society viz., depletion of fossil fuels and environmental pollution. In the present work, experiments are carried out on a Single cylinder diesel engine which is commonly used in agricultural sector. Experiments are conducted by fuelling the diesel engine with bio-diesel with LPG through inlet manifold. The engine is properly modified to operate under dual fuel operation using LPG through inlet manifold as fuel along FME as ignition source. The brake thermal efficiency of FME with LPG (2LPM) blend is increased at an average of 5% when compared to the pure diesel fuel. HC emissions of FME with LPG (2LPM) blend are reduced by about at an average of 21% when compared to the pure diesel fuel. CO emissions of FME with LPG (2LPM) blends are reduced at an average of 33.6% when compared to the pure diesel fuel. NOx emissions of FME with LPG (2LPM) blend are reduced at an average of 4.4% when compared to the pure diesel fuel. Smoke opacity of FME with LPG (2LPM) blend is reduced at an average of 10% when compared to the pure diesel fuel.

Realizing decreased CO2 emissions from the transport sector will be possible in the near future when substituting (part of) the currently used hydrocarbon-fuelled internal combustion engines (ICEs) with hydrogen-fuelled ICEs. Hydrogen-fuelled ICEs have advanced to such a stage that, from the engine point of view, there are no major obstacles to doing this. The present paper indicates the advantages of hydrogen as a fuel for spark ignition (SI) internal combustion engines. It also shows how the hydrogen engine has matured. An extensive overview is given of the literature on experimental studies of abnormal combustion phenomena, mixture formation techniques, and load control strategies for hydrogen-fuelled engines. The Transport Technology research group of the Department of Flow, Heat and Combustion Mechanics at Ghent University has been working on the development and optimization of hydrogen engines for 15 years. An overview of the most important experimental results is presented with special focus on the most recent findings. The article concludes with a list of engine design features of dedicated hydrogen SI engines.

There is an increase demand in EV which will play a major role in future of road transport. While commercial Electric Vehicle existing today have their uptake has been limited due to limited battery range, lack of charging convenience and high purchasing cost. As cities expand and affluence rises, traffic congestion is becoming problematic. To respond to these core challenges facing the transportation sector, the E-highway is twice as efficient as internal combustion engines. The innovation includes transition from personal combustion powered vehicles towards grid-powered transportation. This innovation supplies trucks with power from overhead contact line. This reduces local air pollution and contributes significantly to the decarbonization of the transport sector.

AbstractFor now, biodiesel is the commonly accepted biofuel as a substitute for diesel fuel in internal combustion engines. Diesel fuel blends with up to 20% biodiesel can be used in diesel engines without any modification. A lot of studies regarding diesel fuel+biodiesel blends properties are presented in the literature. Some of the important properties of diesel fuel+biodiesel blends can be evaluated from other blends properties. For example, density and viscosity of biodiesel blends can be predicted based on blend refractive index. More than that, refractive index can be used as a reliable physical property to predict transesterification reaction progress. As a result, the refractive index of diesel fuel+biodiesel blends is important in order to characterize these blends or to monitor the evolution of transesterification process of vegetable oils or animal fats. The refractive index of diesel fuel+biodiesel blends can be experimentally determined or evaluated based on refractive indices of diesel fuel and biodiesel. The aim of this study was to estimate the accuracy of refractive index of diesel fuel +biodiesel blends calculation, using models initially proposed to evaluate the refractive index of a binary liquid mixture. It was shown that the refractive index of diesel fuel+biodiesel blends can be accurately predicted from refractive indices of the components of the blend. Wiener, Heller and Edward equations can be recommended to predict with a great accuracy the refractive index of diesel fuel+biodiesel blends.
