Opis:: Compression ignition engines are a major source of air pollution in big cities and the cause of smog. Therefore, it seems appropriate to quantify emissions of toxic components of combustion gases by compression ignition engines. In the paper, it was presented emission measurement results of selected components of exhaust gases such as CO, CO2, HC, O2, NOx, by indirect injection compression ignition engine. The object of the study was Andoria 4CTi90 engine. The research was carried out at the AVL engine test bench. Measurement results were shown in the form of external and load characteristics. It was interesting to compare the emissions of individual exhaust components of the 4CTi90 engine with the contemporary direct injection engine. The measurements carried out at the Department of Automotive Engineering at the West Pomeranian University of Technology in Szczecin on the Fiat 1.3 JTD Multijet engine showed that the emissions of the considered exhaust gas components in conditions of external characteristics, for the rotational speed of 4000 1/min, were much higher than the Andoria engine. The study assumed the measurement of hydrocarbon emissions, however, within almost the entire range it was zero. Only for the speed of 4000 min-1, the meter showed values slightly higher than zero. The authors believe that it would be interesting to compare the exhaust emissions of the 4CTi90-1BE engine and the ADCR engine.

Opis:: Noise and vibration of ignition compression engine is one of the most complicated fields to cope with since every mechanism that compose of the engine affect them separately. In this study, effect of diesel on engine noise and vibration has been studied on an unmodified compression ignition engine. Noise and vibration characteristic of a direct ignition engine, which was fuelled with diesel, were investigated. With the usage of equations obtained from regression analysis, estimation of engine characteristic fuelled with various biodiesels researches were carried out. Tests were conducted at fixed injection timing of diesel fuel. The first system is for diesel fuel injection; the second one is PFI (port-fuelled injection) and is used for injecting alcohol into the engine intake manifold. The engine applied to this study was a naturally aspirated, 3in-line, IVECO AIFO 8031 i06.05 diesel engine with direct injection. Experiments were conducted in a sound insulated room. For each experiment, vibration data gathered from the engine block with 3.2 kHz (for vibration) for 2 s and with 20 kHz sampling frequency for 0.320 s. All measurements were performed under conditions: angle 10; 4 different loads (4, 8, 12 and 20 kW).

Opis:: Continuous monitoring of diesel engine performance under its operating is critical for prediction of malfunction development and subsequently functional failure detection. Analysis of Instantaneous Angular Speed (IAS) of the crankshaft is considered as one of non-intrusive and effective method of detection of combustion quality deterioration. The article contains presentation of attempt of monitoring of piston engine’s crankshaft torsional vibrations by measurement of Instantaneous Angular Speed at free, and power output ends of the engine’s crankshaft. The angular speed measurements was done using two optical sensors for reading the IAS, mounted at shaft line’s opposite ends, one at free end of the crankshaft and second at end of generator’s shaft. In the article is presented description of the measurement system and explanation of its mode of work. Experiments were based at two kinds of malfunction possible to be simulated at test bed. First one was simulation of a leak of fuel injection pump, the second one relayed on mounting of sets of injection valves with different nozzles characteristics (spraying nozzle angle), giving different parameters of fuel injection. Presented results of experiment derives from test cycle carried out using laboratory stand of Gdynia Maritime University equipped with 3- cylinder self − ignition engine, powering electric generator.

Opis:: The assessment of renewable fuels on the basis of the results of internal combustion engine’s tests is not clearly good or not good. Biofuels can be a part of sustainability from energy sources, energy security and energy diversity point of view. But they cannot be assessed better compared to the fossil diesel as for their combustion and air pollution and the engine’s external parameters. Comparison test series has been conducted with three different fuel and their controlled blends. These fuels were fossil diesel, the conventional, standardized biodiesel, and a new type biodiesel, which is the so-called TBK-biodiesel. These tests covered the physicochemical properties of the fuels, the engine external parameters, the combustion parameters and the exhaust emission of an internal combustion compression ignition engine. Furthermore, external costs have been calculated based on the emission results. Physicochemical properties, engine parameters, combustion parameters, exhaust emission and external costs have been observed as parameter groups, which contain many parameters. A complex evaluation could be built with the help of such kind of parameter set. On the basis of the results, it can be established that almost in the most cases the direction of the parameters’ changes is negative. Thus, the evaluation’s centre of gravity has been observed as shifted in the negative direction.

Opis:: In recent years, the compression ignition engines with direct injection equipped with common rail system are subject to intensive development. Mainly, the reason for it the ecological considerations are. Generally, the engines of this type are characterized by relatively low specific fuel consumption, lower noisy and lower emission of toxicity components in relation to DI engines with conventional injection system. Especially the main advantage of common rail system is possibility of easy controlling the injection parameters. Particularly a possibility of splitting the fuel dose into several parts within the one engine cycle permits to influence on combustion process. In the paper, the effect of injection characteristic on NOX formation in DI engine equipped with common rail injection system is presented. In principle, the course of injection by pilot, preinjection and main fuel dose was shaped. The fuel dose quantities were changing by choosing of injector opening duration. The distances between parts of injection were changed too. The researches were conducted at constant rotational speed of engine. Whole researches by using the test engine equipped with common rail injection system were realized. The following parameters were measured during researches: rotational speed, power, hour fuel consumption, rate of air flow into engine and concentration of NOX and HC in exhaust gases. Also high speed parameters were recorded such as pressure in combustion chamber, injector control signals and pressure in inlet manifold.
W ostatnich latach intensywnemu rozwojowi podlegają silniki wysokoprężne z bezpośrednim wtryskiem paliwa wyposażone w akumulacyjne układy zasilania typu Common Rail. Jest to podyktowane głównie względami ekologicznymi. Ogólnie, silniki tego typu charakteryzują się stosunkowo niskim jednostkowym zużyciem paliwa, mniejszą hałaśliwością i mniejszą emisją toksycznych składników spalin w stosunku do silników typu DI z konwencjonalnym układem wtryskowym. Szczególnie ważną zaletą zasobnikowych układów wtryskowych jest możliwość łatwego sterowania parametrami wtrysku. Zwłaszcza możliwość podziału dawki paliwa na kilka części w obrębie jednego cyklu pracy silnika pozwala na istotne oddziaływanie na przebieg procesu spalania. W artykule przedstawiono wpływ charakterystyki wtrysku na powstawanie NOX w silniku typu DI wyposażonym w układ wtryskowy typu Common Rail. Charakterystyka wtrysku zasadniczo ukształtowana była przez dawkę pilotującą, przedwtryskową i zasadniczą. Wielkość tych dawek zmieniana była przez zmianę czasu otwarcia wtryskiwacza. Zmianom podlegały także odległości kątowe pomiędzy składowymi dawki paliwa. Badania prowadzone były przy stałej prędkości obrotowej silnika. Całość badań realizowana była na jednocylindrowym silniku badawczym z zaadoptowanym do niego układem wtryskowym typu Common Rail. Podczas badań pomiarom podlegały między innymi następujące parametry: prędkość obrotowa, moc, godzinowe zużycie paliwa, masowe natężenie przepływu powietrza do silnika oraz stężenie tlenków azotu NOX i węglowodorów HC w spalinach. Rejestrowano także parametry szybkozmienne takie jak: ciśnienie w komorze spalania, sygnały sterujące pracą wtryskiwaczy, ciśnienie w układzie dolotowym.
