Opis:
Biodiesel is widely perceived as a source of ecological energy used to power compression ignition engines as an alternative to fossil fuels. Depletion of fossil fuels and increasing environmental awareness of society has led to an increased demand for energy derived from renewable sources. This phenomenon requires acquisition of raw material used for biofuel production. In order avoid controversies related to misuse of edibles; sources of biofuel production should be viewed as inedible or waste materials. This paper presents an analysis of possible sources of animal material intended for biofuel production. An examination of the quality assessment for biofuels obtained in the laboratory setup, produced from swine lard and turkey fat is presented. The results have been compared to rapeseed biofuel and commercial diesel fuel as fuels commonly used to power compression ignition engines. The paper concerns an examination of pure biofuels and their mixtures with commercial diesel fuel in three different proportions. Parameters such as density, viscosity, acid value, cold filter plugging point, oxidation stability, sulphur content, total contamination, water content and flash point has been examined according to procedures outlined in the PN-EN 14214 Standard. Based on the results, biofuels and their mixtures have been analysed for use in compression ignition engines.

Opis:
Increased interest in development of alternative fuels used to power combustion engines is caused by excessive use of fuels obtained from mineral sources. Depletion of resources, political aspects as well as the negative impact on the environment are commonly discussed issues in relation to fossil fuels. On the other hand, biodegradability, lower toxic components emissions and interchangeability with mineral fuels are commonly described benefits related to biodiesel, interpreted as fatty acid methyl esters obtained from fatty raw material. Also the multiplicity of raw materials that can be used for production promotes popularization of the biodiesel. However the variety of raw materials can have significant impact on the number of physicochemical properties of alternative fuels due to the differences in molecular structures forming given type of raw material. The article presents analysis of properties of different types of biodiesel and its mixtures with diesel according to the outlines presented in the quality standards for mineral and alternative fuels. Alternative fuels were produced in the laboratory setup from swine, poultry, rape and sunflower fatty raw material. Such parameters as: density, kinematic viscosity, flash point, acid value, oxidation stability, cold filter plugging point, sulphur content, water content and total contamination were examined, based on the results, the quality of the biofuels was evaluated. Study confirms that biofuels derived from plant origin fatty raw material present favorable results in the aspect water content, total contamination, acid value and cold flow properties, thus biofuels derived from animal origin raw fatty material presents lower density and sulphur content.

Opis:
The use of renewable fuels can reduce consumption of fossil fuels as well as diversify the range of alternative energy carriers. The advantage of biofuels is that they can be obtained from waste materials. Biofuels derived from vegetable or animal raw fatty material, as a result of transesterification, are characterized by similar physicochemical properties to mineral diesel fuel in terms of quality standards, however the fatty acid composition of the raw material can significantly influence exhaust gas emissions. The aim of the research is to determine the impact of the origin of various renewable biocomponents on exhaust gasses concentration emitted by compression ignition engine. The tests were conducted on a Common Rail, direct injection engine, operating under steady state conditions. Two kinds of biofuels produced from different fatty raw materials (rapeseed oil and swine lard) were used. All the experiments were performed on fuels containing a total of 50% biocomponent shares admixed to commercial diesel fuel. The tested samples included both: binary and ternary mixtures. During the experiments the differences in: hydrocarbons, carbon monoxide and nitrogen oxides concentrations were examined as a result of different fuel composition. The study shows that the best results were achieved for fuel containing both plant and animal biocomponents.

Opis:
The use of internal combustion engines increase environmental pollution and dependence on fossil fuels. The biodiesel fuel, which is renewable, more environment friendly, and cheaper, is a good alternative for diesel engines. The use of biodiesel fuel leads to a drop in diesel power and an increase in fuel consumption. To prevent these shortcomings, it is proposed to use dynamic regulation of the percentage composition of a mixture of diesel and biodiesel fuel. The modernization of diesel engines for their transfer to work on a mixture of fuels with a dynamic regulation of its percentage composition is possible at service stations serving diesel engines.

Opis:
Analytical and experimental data on fire hazard of diesel bio fuel, its mixtures with oilbased diesel fuel, and parameters of processes of their burning and interaction with fire-extinguishing agents. Applicability of the types of fire-extinguishing agents having been used for putting-out of diesel bio fuel was revealed and a number of parameters to describe their efficiency when extinguishing diesel bio fuel were determined. It was revealed that in case of diesel bio fuel content in its mixtures with oil-based diesel fuel up to 30% fire-extinguishing efficiency of foam generated from foam solutions nearly does not differ from that when extinguishing diesel fuel containing no additives.
