Opis:
Paper presents schematic description of the research covering production mechanism of Fatty Acid Ethyl Esters (FAEE) from waste vegetable and animal fats, which are creating a base for multi-component fuel BIOXDIESEL as well as results of physical, chemical analysis and results of engine and vehicles tests. The characteristic of wasted material used for production of fatty acid ethyl esters is showed. Cybernetic chain of biofuel BIOXDIESEL, system analysis and structure and scheme of the chemical reaction of Ethanol esterification of fatty acids is presented. Basic properties of exemplary BIOXDIESEL and Diesel fuel were compared. Caloric values of investigated BIOXDIESELS are shown. Mixtures of the BIOXDIESEL fuels with various composition have been tested and compared with Diesel fuel during engine tests on the engine test bench, vehicle test dyno and drive tests. The diesel engines of Fiat 1.3 Multijet, Mercedes300D, Landrover and ADCR compression ignition engine were tested with biofuels. Functional schema of the measurement set up is described. Cyclodynes obtained during testing of the ADCR engine fuelled with Diesel and BIOXDIESEL fuels with their centres of gravity are presented. Obtained and described results in the form of tables and graphs can be summarized with conclusions, that the performance of engines fuelled with BIOX-DIESELS is similar to engines fuelled with Diesel fuel.

Opis:
The World is strongly dependent on crude oil for its transport needs. In order to diminish this dependence, we need to introduce clean, CO2-efficient, secure and affordable transportation fuels. The current production of liquid biofuels in the EU25 is less than 1% of the market. Recent assessments have concluded that the 2010 targets, 18 Mtoe used in the transport sector, are unlikely to be achieved. There can be three basic possibilities of accomplishing this target: i) use of alcohols (first of all ethanol) and their mixing with petrol; ii) use of fatty acids esters (methyl or ethyl) of vegetable oils and their mixing with diesel fuel, iii) use of synthetic hydrocarbons of the synthetic gas coming from biomass resources and eventually their mixing with other "classical" hydrocarbons. This paper presents a novel way of utilizing alcohols as fuels for a diesel engine. It is proposed to use heavy alcohols as a mix with vegetable oils and conventional diesel fuel. It is presented the way to use alcohols. Namely, the use of heavy alcohols as a solvent for vegetable oil (named the biomix or BM) and after the obtainment of the thickness, which would be approximate to diesel fuel, mixing the biomix with diesel fuel to obtained biomixdiesel (BMD). This solution will be shown for example with butanol as heavy alcohol, rape oil as vegetable oil and conventional diesel fuel. The investigations are carried out with a simple diesel engine on the engine test bed. Main parameters of engine (power output, torque, specifically fuel consumption) and the main exhaust gas component (in this case CO, NOx, PM) will be investigated. There were better results achieved than one expected. Opposed to existing experiences, the maximum of power output and the torque of engine are higher in the whole range of the rotational speed of the engine crankshaft when the engine biomixdiesel (BMD) is reinforced. The addition of the component biomix to fuel influences the specific fuel consumption. Generally, with the larger part of the component biomix the specific fuel consumption grows. Because the power of engine also grows up one should expect that in exploitation the specific fuel consumption should not increase. Very important is that this fuel could be used to reinforce old, existing now and the future diesel engines. The production of butanol is known (from biomass and in other way with electrolysis of ethanol). The possibility to get butanol from ethanol gives a very good perspective for the use of ethanol from today's overproduction and moreover without the essential change of infrastructure. All this leads to the conclusion that fulfilling of the expected requirements of European Union regarding the ecofuels is fully possible.

Opis:
This paper presents results of the research on the efficiency of the Diesel engines of the fleet vehicles fed with the new type of second-generation biofuel BIOXDIESEL at non-stationary and stationary conditions and natural operation on roads. The BIOXDIESEL fuel used for the laboratory testing of physical and chemical properties, engine tests and natural road operation, which is a blend of fatty acid ethyl esters (FAEE) obtained from the waste vegetable and animal fats, bioethanol and Diesel fuel. For the testing, several different types of vehicles have been used: passenger vehicles, small parcel delivery vans, agriculture machines and heavy trucks used for long distance international transport. The results of the vehicles engines testing in non-stationary conditions, results of measurement engines performance on vehicle test bed and results of natural road operation on roads of the vehicles used for testing indicate quasi-identical efficiency of the engines, which were fueled with BIOXDIESEL fuel and standard Diesel. The paper also presents results of initial research, which indicates the direction of future research, which is related to increase the calorific value of the biofuels, which may be obtained by replacement of used bioethanol with the heavier alcohols of renewable resources. Physical and chemical properties of the heavier alcohols indicate the possibility to use them as an additive to the biofuels. The paper presents also results of initial engine tests with a blend of the fuel with different heavier alcohols.

Opis:
Due to the continuous increase in prices of conventional fuels, the production of biofuels on an industrial, as well as small scale, nowadays is becoming more economically efficient. However, the usage of biofuels in its pure form is a problem when one have to supply them with modern injection systems. Due to the difference in parameters of biofuels in comparison with conventional fuels, the attempt to develop a mixture of optimal parameters for use in diesel engines, equipped with modern injection system, was made. Fuels derived from substrates which are produced independently of food production and which can energize CI engines are occupying now stronger market positions. Easier access to know-how and an uncomplicated production process result in technological development, not only in mass-scale plants but also in smaller devices which meet the needs of individual users or in which residues of other processes are neutralized or reused13 samples were tested, mixed of diesel, FAEE and ethyl alcohol. The mixtures were prepared and tested in The Department of Mechatronics in University of Warmia and Mazury for the most important parameters in the evaluation of possibility of usage to power modern compression ignition engines.
