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 manuscript presents a comparative analysis of the performance and emission characteristics of a compression ignition engine equipped with a Common Rail injection system. The engine is fueled with diesel-biodiesel mixtures containing 25% and 50% share (by volume) of renewable components. Conventional diesel is used as a reference. Turkey lard and rapeseed oil are used as raw materials and subjected to the single-stage transesterification process to obtain methyl esters. The experiments are performed on a medium-duty, turbocharged, inter-cooled, Common Rail Direct Injection (CRDI) diesel engine. This study concentrates on one engine speed of 1500 rpm, typical for gen-set applications, and mid-load range from 100 Nm to 200 Nm. The scope of measurements covers the analysis of exhaust gasses concentration and engine efficiency parameters. In addition, the in-cylinder pressure measurements are performed in order to provide insight into the differences in combustion characteristics between examined fuel mixtures. The study reveals that the addition of the renewable component to fuel mixture positively affects a number of examined performance parameters as well as de-creases the concentration of the examined toxic exhaust components, in the majority of cases.
