    Opis:
    The article presents the impact of hydrocarbon fuel angle of injection on heat emission characteristics in a compression - ignition AD3.152 engine. The angle of injectionhas a significant impact on the primary engine operating parameters and combustion process indicators, which include the proportion of combustion which occurs according to kinetic and diffusion models, heat emission rate and the combustion process duration. The characteristics describing emission of a relative heat quantity were determined on the basis of an analysis of actual, indicator diagrams averaged over 100 runs, under the assumption that the combustion process ends by the time the exhaust valve opens. During the test, the engine operated according to an external speed characteristic. Tests were carried out for three fuel angles of injection: 13, 17 and 21 crankshaft rotation degrees.

    Opis:
    The publication presents test results for a Perkins 1104D - 44TA engine powered by SME sunflower oil fatty acids methyl esters. The SME biofuel was manufactured in-house using a GW-200 reactor at MCOŹE "BioEnergia". The test was carried out at an engine test stand at Kielce University of Technology's Heat Engine Laboratory. During the test the engine operated according to an external speed characteristic. The tests aimed to determine the impact of using an SME type biofuel to power the engine on the engine's primary performance indicator values. A slight decrease to the brake horsepower and torque of the tested engine powered by sunflower oil esters as compared to diesel was recorded. Fuel consumption of the engine powered by plant origin fuel also increased. No operating problems were experienced associated with powering the engine using sunflower oil esters during the tests.

    Opis:
    The paper presents the results of research on the impact of Perkins 1104D-44TA engine powered with sunflower oil methyl esters and, for comparison, with diesel fuel, in terms of emission of CO, THC, NOx and O2. The tests were carried out on the engine test stand. During the tests, the engine worked according to the external speed characteristics in the range from 1000 to 2200 rpm. The esters used for powering the tested engine were produced using the GW 200 reactor designed and made by Grzegorz Wcisło, one of the co-authors of the paper. The results of the tests carried out showed a decrease in the concentration of carbon monoxide in the exhaust gases, hydrocarbons when powering the engine with sunflower oil esters in relation to powering the engine with diesel fuel. At the same time, the concentration of nitrogen oxides and oxygen in the exhaust gases increased. The reduction of THC and CO emissions is the result of better combustion and afterburning of fuel. However, the increase in the amount of oxygen in the exhaust gases results from the fact that in the biofuel structure there is oxygen which is used in combustion and reduces the oxygen demand from the atmosphere. On the other hand, the increase in NOx emissions is the result of a higher combustion temperature than when the engine is powered by diesel fuel.

    Opis:
    The article presents the results of tests determining the impact of using sunflower oil methyl esters on power and torque as well as unitary and hourly fuel consumption of the Perkins 1104D-44TA engine. Biofuels were produced in the Fuel and Energy Laboratory belonging to the Maopolskie Centrum Energii Odnawialnej (Małopolskie Center for Renewable Energy Sources), while analyzes of the selected fuel parameters were performed both in the above-mentioned laboratory and in the Liquid Biofuels Laboratory at the University of Agriculture in Krakow. Engine tests were carried out on the engine test stand at the Kielce University of Technology. During the tests, the engine worked according to the external speed characteristic. The results of the tests have shown that the engine supplied with the SME achieves slightly lower values of both power and torque than in the case of commercial fuel oil type Ekodiesel Ultra from the ORLEN S.A company. There was also an increase, especially in the case of higher unitary fuel consumption. Hourly fuel consumption was higher when supplied with SME in relation to the diesel fuel supply, although not as much as unitary consumption. The increase in SME consumption at the engine supply can be explained by the lower fuel value of SME, which contains oxygen in its structure.

    Opis:
    The aim of the study was to compare the impact of dynamic viscosity of two biofuels. One was a mixture of 50% (m / m) SBME and 50% (m / m) RME of own production. The mixture was conventionally called FAME. The second biofuel was commercial RME from a gas station. Dynamic viscosity as a function of temperature from -20 to 50oC was tested. The main device used at the measuring stand was ReolabQC rheometer manufactured by a German Anton Paar GmbH company. Dynamic viscosity especially grew rapidly after cooling biofuels to temperatures below -5°C. Dynamic viscosity FAME biofuels produced from pure vegetable oil (soybean oil and rapeseed oil) in a temperature range of 50 to -20°C has a value of c.a. 9 to 53[mPa∙s]. Dynamic viscosity of Biofuel FAME produced from mixtures of vegetable oils it was on average lower by about 1 to 8 [mPa∙s] of RME shopping from a gas station.
