Opis:: The results of SI engine fueled with blends of LPG and DME are presented in the paper. The range studies submitted includes measurements at varying engine loads, at selected values of speed. The research was conducted on a chassis dynamometer, specifying the engine load by the degree of throttle opening. Value of the mass fraction of DME in the blend with LPG was determined based on previous analyzes. The selected fuel blends containing from 7 to 17% DME (mass fraction). During the study was also performed a series of comparative measurements with pure LPG. Analyses show that of DME can be used as a partial substitute for LPG in SI engines. Its presence does not a negative impact on performance and emissions of the engine. The obtained results indicate that the amount of addition of DME should be varied depending on the engine load. Moreover, the use of this fuel does not require changes to the design fueling system and storage of LPG.

Opis:: This paper presents the results of SI engine tests, carried out for different gaseous fuels. The analysis carried out made it possible to define the correlation between fuel composition and engine operating parameters. The tests covered various gaseous mixtures: methane with hydrogen from 5% to 50% by volume and LPG with DME from 5% to 26% by mass. The first group, considered as low-carbon-content fuels can be characterized by low CO2 emissions. Flammability of hydrogen added in those mixtures realizes the function of the combustion process activator. Thus, hydrogen addition improves energy conversion by about 3%. The second group of fuels is constituted by LPG and DME mixtures. DME mixes perfectly with LPG, and differently than other hydrocarbon fuels, consisting of oxygen as well, which makes the stoichiometric mixture less oxygen demanding. In the case of this fuel an improvement in engine volumetric and overall engine efficiency has been noticed compared with LPG. For the 11% DME share in the mixture an improvement of 2% in the efficiency has been noticed. During the tests, standard CNG–LPG feeding systems have been used, which underlines the utility value of the research. The stand-test results have been followed by combustion process simulation including exhaust forming and charge exchange.

Opis:: The paper presents a continuation of a research program related to the activators for gaseous fuels used in modern vehicles. Selected vehicle dynamic parameters obtained by the application of a mixture of LPG and DME for the mass share of 0 to 26 % have been presented. The object of the research was a 1.6 SI engine adapted to a combustion of gaseous fuels. The authors present the results of the energy conversion efficiency in a four cylinder SI 1.6 cm³ engine.
Artykuł prezentuje wybrane wyniki badań nad aktywatorami spalania alternatywnych paliw gazowych, wykorzystywanych do napędu pojazdów samochodowych. Określono wpływ udziału DME w mieszaninie DME-LPG na sprawność przetwarzania energii w silniku ZI. Obiektem badań był czterocylindrowy silnik napędzający samochód Opel Astra, wyposażony w dodatkowy układ zasilania, typu PFI. W badaniach wykorzystano mieszaniny DME-LPG o udziale masowym DME od 0 do 26 %. Dla każdej z mieszanin zrealizowano kilka serii pomiarowych, w ustalonych warunkach pracy silnika. Wyjaśniono wpływ udziału DME w mieszaninie na osiągi silnika, a także podstawowe parametry charakteryzujące proces spalania. Stwierdzono, że masowy udział DME nieprzekraczający 11 % wpływa na zwiększenie sprawności przetworzenia energii, przyrost ciśnienia, stopień wypalenia ładunku i ilość wydzielanego ciepła.

Opis:: The paper presents the results of tests on a SI engine fueled with an LPG/DME blends of various composition. A number of experimental studies and calculations using a mathematical model were carried out to examine the suitability of this fuel. These tests allowed for the analysis of the changes taking place in the combustion process and the assessment of the main operating parameters of the engine. The engine was powered by an LPG/DME fuel mixture with different proportions of components. The share of DME ranged from 0% to 30% of the fuel mass. The obtained results reflect the operation of the engine in the full load range and selected rotational speeds. Measurement series were made for different settings of the ignition advance angle. Based on the obtained results, a corrected map of the ignition advance angle was developed. The obtained results confirm the usefulness of using the LPG/DME mixture to power the SI engine.

Opis:: The paper presents the results of tests of the SI engine fuelled by LPG with the addition of DME in the form of a mixture of gaseous fuels. Experimental tests were carried out on a chassis dynamometer in the full range of engine loads, at a fixed rotational speed: 2000, 2500 and 3000 rpm. The use of dimethyl ether (DME) as a fuel component makes it possible to exploit its important advantages. DME can be produced as a renewable fuel, which is important from the point of view of ecology. Another important fact is the presence of oxygen in this fuel, which has a positive effect on the engine volumetric efficiency. During the tests, the ignition timing was also adjusted due to the very good DME flammability. Two additional correction levels were applied, increasing the ignition advance by 3 and 6 CA degrees, compared to the factory settings of the driver. The analysis of the obtained results allowed determining the dependence of the basic engine parameters, in the function of the correction of ignition advance angle. In the summary, attention was also paid to the possibility of determining corrected maps of the ignition advance angle taking into account the variable proportions of fuel components.
