Opis:
The article presents possibilities of implementation gas, came by wood biomass gasification, to run on internal combustion engines powered normally by Diesel fuel. Carbonization, gasification and burning effects were introduced. Main processes occurring during biomass gasification were shown. Basic chemical reactions characteristic to each stage were named. The differences in composition of received gas according to sort of biomass, gasification medium and type of generator were mentioned. In article were depicted way of modus operandi and structures of typical generators along with its advantages and disadvantages. gas properties obtained by this method and its main parameters were presented. The advantages and disadvantages posed by the use of wood gas in internal combustion engines were described. Parameters of the gas that should be amended to allow the engine to be powered were listed. Also were shown ways of changing these parameters. Necessary engine modifications to be able to supply it with wood gas were presented. The article finishes with conclusions and risks resulting from the use of this technology and also possible impact on the environment.

Opis:
In relation to the scantiness of stores and the constantly increasing demand for energy, societies are forced to seek alternative energy sources. Biofuels that is fuels produced of biomass are one of them. The most important biofuels are bioethanol (produced from sugar cultivations and cereal crops, used with petrol) and biodiesel (ester produced mainly of vegetable oils; serves as the substitute or the addition to diesel). The esters of vegetable oils production requires using appropriate apparatus which enables to produce esters with parameters defined in very exacting legal norms about the quality of such fuel. In the paper were described results examining the quality of esters and mineral oils made with the use highly specialist, new generation 's apparatus which fulfll the conditions defining in the relevant norm. Results of those surveys are showing that using simple methods in production such biofuel doesn 't let for getting the product with parameters defined by the law. Applying fuel with lowered standard parameters influences on observed cases of improper functioning of fuel apparatus in engines with self-ignition, mainly in case of high pressure systems (e.g. Common Rail).

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.
