    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 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:
    Increasingly higher demands pnt on piston internal combustion engines arę aimed at reducing their harmful impact on the natural environment. This refers primarily to nitrogen oxides, particulate matter and noise emissions. The reduction in emissions ofnoxious components oj exhaust gases in engines is achieved by means of, among others, the use of catalysts decreasing nitrogen oxide emissions, particulate matter filters and oxidising catalysts decreasing carbon monoxide and hydrocarbon emissions. Common Rail injection systems make it possible to increase the engine power, and to reduce fuel consumption, exhaust gas toxicity and noise produced by engines. With Common Rail systems, the pattern of fuel injection process can be designed, consequently the combustion process can be controlled. The paper presents the results of test bench investigations into a compression ignition 1.3 Multijet engine with multistage fuel injection, which is manufactured in Poland by Fiat-GM Powertrain Polska Company. The tests were conducted at a stand constructed at the Heat Engines Laboratory ofthe Kielce University of Technology. The scope of investigations included determining economic and energetic parameters of the engine work, and also environmental parameters, such as the concentration of nitrogen oxides NOX, carbon monoxide CO and carbon dioxide CO2 in exhaust gases, and exhaust gas smokiness. In tests, the engine operated under speed conditions and it was fuelled by two commercial diesel oils that had different physical and chemical properties.

    Opis:
    Fuels constitute one of the research areas within the scope of piston internal combustion engines. The works encompass both conventional as well as alternative fuels. Fuels are sought which will contribute to a reduction in the negative impact of transport on the natural environment and humans. These may be fuels obtained from organic raw materials of agricultural (most often) or forest origin. When it comes to compression-ignition engines, Biodiesel B100 type biofuels can be used to fuel them, which most often constitute a long chain fatty acid ester, made from plant oils or animal fats. The publication presents ecological indicator test results for a compression – ignition engine fuelled by SME Biodiesel, or sunflower oil methyl esters and commercially available diesel as a benchmark. During the tests, the engine operated according to load characteristics at two different crankshaft rotational speeds. A sunflower oil ethyl ester fuelled engine returned beneficial values for most of the tested ecological indicators as compared to a diesel fuelled engine. Concentrations of substances such as CO, CO2, unburned hydrocarbons (THC), particulate matter (PM) were lower in the engine emissions, exhaust smoke levels were also reduced. Only nitrogen oxides (ONx) increased.

    Opis:
    W artykule przedstawiono wyniki hamownianych badań silnika o zapłonie samoczynnym 1.3 Multijet z wieloetapowym wtryskiem paliwa produkowanego w Polsce przez Firmę Fiat-GM Powertrain Polska. Badania przeprowadzono na stanowisku hamownianym zbudowanym w Laboratorium Silników Cieplnych Politechniki Świętokrzyskiej. Zakres badań obejmował wyznaczenie wskaźników ekonomiczno-energetycznych silnika oraz jego wskaźników ekologicznych takich jak stężenia NOx, CO i CO2 oraz stopień zadymienia spalin. Podczas badań silnik pracował według charakterystyk obciążeniowych przy prędkościach obrotowych wału korbowego: n = 1200, 1750, 2400, 3800, 4000 i 4200 obr/min. Prędkości te wybrano ze względu na realizację w badanym silniku wieloetapowego wtrysku paliwa oraz ze względu na możliwości rozwijania przez silnik maksymalnego momentu obrotowego Mo = 200 Nm, przy prędkości obrotowej wału korbowego n = 1750 obr/min oraz maksymalnej mocy Ne = 66 kW osiąganej przy n = 4000 obr/min.

The scope of investigations included determining economic and energetic parameters of the engine work, and also environmental parameters, such as the concentration of nitrogen oxides NOx, carbon monoxide CO and carbon dioxide CO2 in exhaust gases and exhaust gas smokiness. During the tests, the engine operated under load conditions at the crankshaft rotational speed: n = 1200, 1750, 2400, 3800, 4000 and 4200 rpm. Such values of speed were selected because of the multi-stage fuel injection and the engine's being able to reach the maximum torque Mo = 200 Nm at the crankshaft rotational speed n = 1750 rpm and the maximum power output Ne = 66 kW, delivered at n = 4000 rpm.
