Opis:
Modern marine Diesel prime movers are equipped with so called ‘common rail’ as a part installed in the fuel injection system. This kind of design, gives a possibility to control fuel injection process in ways which were not available to carry out on conventionally designed engines. During the ship operation with a reduced speed and reduced load of the main engine, especially under the “Super Slow Steaming” conditions the waste heat recovery process in exhaust gas boiler is being disturbed. In the article, there is presented a possibility to increase the steam production of the waste heat boiler by interference in the fuel injection pattern for the engine. For the selected system “low speed main engine – smoke tube exhaust gas boiler” the test session has been carried out under the real ambient and operational condition of the ship to verify described possibility. Obtained results have been presented.

Opis:
The issues addressed in this paper concern the effect of pressure in the Common Rail accumulator on the engine operating parameters such as its torque, power output, rotational speed as well as its hourly and specific fuel consumption. Here, the research methods were performed by using the engine test bench strictly in accordance with the specific standards but particularly according to the requirements specified by these standards. The research station was the Fiat Multijet 1.3 JTD engine with turbocharging and direct injection, used as a power unit in the motor cars. Additionally, the experimental tests were run by using also (1) the HP-made measuring set for measurements the high pressure (up to 2,500 bars) in the Common Rail system, and (2) the CDIF/2 diagnostic interface. All relationships are presented in the form of graphs, and what is found here is the increasing linear relationship between the p rail pressure and the engine speed: with an increase in speed comes a decrease in the total injection time. The torque and its power output were a function of both the pressure in the Common Rail accumulator and the speed. It was found that the highest total engine efficiency (fuel consumption per unit) was for the rail pressure ranging from 1,000 to 1,100 bars. The findings come up for discussion about the apt choice of pressure in the rail, together with the total injection time and the turbocharger highest efficiency, for the specified speed of a car power unit.

Opis:
The paper presents the methodology for testing Common Rail fuel injectors, which involved extending standard test procedures with additional measurement points and introducing a linear regression coefficient as a new diagnostic parameter. This allowed for a more precise checking of the fuel dosage method, as the active experiment was conducted at a wider range of nozzle opening times (actuation). The obtained results were used in the calculation stage, which was transferred to the popular spreadsheet environment. This eliminates the need to modify the test bench software. The proposed solution should be particularly useful in problematic situations in which a clear assessment of the technical condition of the fuel injector remains difficult, as shown in the example.
W artykule przedstawiono metodykę badań wtryskiwaczy common rail, która polegała na poszerzeniu standardowych procedur testowych o dodatkowe punkty pomiarowe i wprowadzeniu współczynnika regresji liniowej jako nowego parametru diagnostycznego. Pozwoliło to na bardziej precyzyjne sprawdzenie sposobu dawkowania paliwa, gdyż eksperyment czynny prowadzono przy szerszym zakresie czasów otwarcia rozpylacza (wysterowania). Uzyskane wyniki wykorzystano w fazie obliczeniowej, którą przeniesiono do środowiska popularnego arkusza kalkulacyjnego. W ten sposób wyeliminowano konieczność modyfikacji oprogramowania stołu probierczego. Proponowane rozwiązanie powinno być szczególnie przydatne w sytuacjach problematycznych, w których jednoznaczna ocena stanu technicznego wtryskiwacza pozostaje utrudniona, co pokazane zostało na przykładzie.

Opis:
The paper presents a new methodology for testing common rail fuel injectors, which extends the standard diagnostic procedure to include the analysis of the resultant fields of dosed fuel. The calculations were made on the basis of Gaussian formulas, also known as the shoelace formula. Their implementation in the digital environment was convenient from the practical side, as it eliminated the need to modify the test bench software. Thanks to the easy modification, the presented algorithms can be used in testing fuel injectors of other types or generations, for which clear assessment and verification of the technical condition is sometimes difficult. It is not required for this to increase the number of measuring points of the active experiment, which is one of the greatest advantages of the proposed solution.
W artykule przedstawiono nową metodykę testowania wtryskiwaczy common rail, która rozszerza standardową procedurę diagnostyczną o analizę wynikowych pól dawkowanego paliwa. Obliczenia prowadzono w oparciu o wzory Gaussa, określane również mianem formuły sznurowadła. Ich implementacja w środowisku cyfrowym była wygodna od strony praktycznej, gdyż wyeliminowała konieczność modyfikacji oprogramowania stołu probierczego. Dzięki łatwej modyfikacji prezentowane algorytmy można wykorzystać w badaniach wtryskiwaczy innych typów czy generacji, dla których jednoznaczna ocena i weryfikacja stanu technicznego bywa utrudniona. Nie jest przy tym wymagane zwiększanie liczby punktów pomiarowych eksperymentu czynnego, co stanowi jedną z największych zalet proponowanego rozwiązania.

The paper presents the methodology of testing common rail fuel injectors, which consisted in extending the standard diagnostic procedures with the analysis of the resulting fuel delivery fields. The calculations were carried out in a popular spreadsheet, using Gauss's formulas (the so-called shoelace formula). In this way, the necessity to modify the test bench software was eliminated, as the analytical process took place after the end of the active experiment phase. It has been shown that the proposed solution should be particularly useful in problematic situations where clear-cut verification and assessment of the technical condition of the fuel injectors is sometimes difficult, as shown in the example. In addition, implementation in a digital environment allows the presented algorithms to be reused in research with a similar profile.

Opis:
The article presents the laboratory tests results of the influence of the diesel oil content in a mixture with rapeseed oil on the operating parameters of a diesel engine with the CommonRail fuel supply system. Fuel mixtures with a rapeseed content of 0%, 50%, 70%, 100% were used. The article presents the results of tests carried out for various configurations of the object. The measurements included tests of exhaust gases: the content of carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides as well as specific fuel consumption and exhaust gas temperature. As a result of the research, it was noticed that the use of rapeseed oil causes a significant increase in fuel consumption and an increase in emissions. At a crankshaft speed of 2500 rpm and a torque generated by the engine crankshaft of 12 Nm, the specific fuel consumption for a 0% rapeseed content is 310 g/kWh. For the same engine operating conditions and the same rapeseed content of the fuel, the fuel consumption for 100% rapeseed content is 330 g/kWh. For the same engine operating parameters, analysis of the carbon dioxide content in the exhaust gas yields a value of 7.8x104 ppm for a rapeseed content of 0%. For the same engine operating conditions and for the oilseed rape content in the fuel is 100% 8.4x104 ppm. The mathematical models describing the effects of engine operating parameters and rapeseed oil content in the mixture on the observed values were created with the Scilab program. The degree of agreement of the determined mathematical models was checked by calculating the coefficient of determination (R2). The results are shown in 3D figures.

Opis:
In recent years the use of alternative fuels based, among other things, on vegetable oil is causing increasing concern, which is also observed in our country. Such fuels have different physical and chemical properties (especially viscosity) with reference to the standard diesel fuel. Therefore it is important to know the effect of the additive of biocomponents on fuel injection process, in particular of its parameters, which play an important role in the combustion process and formation of pollutions in exhaust gases. In the paper is presented the test results of selected parameters of the injection process executing by four different electromagnetically controlled injectors using diesel fuel without the biocomponents and mixtures of such fuel with esters of rapeseed oil (FAME). Investigations were carried out on a specially prepared test stand which enables the measurement of fuel delivery and fuel returning from the injector together with its density and temperature. Additionally, beside mentioned parameters, there were recorded high-speed courses of pressure in the high-pressure pipe behind the rail and before the injector. Next, using a system of AVL Visioscope, the fuel injection into the visualization chamber filled with fuel was recorded. It determined the basic parameters of the fuel spray. The aim of this study was to determine the impact of fuel type on the injection process executed by the injectors with different constructional parameters.

Opis:
The objective of this study was to determine changes in fuel delivery rate by common rail system injectors during their simulated operation on a test stand. Four Bosch injectors used, among others, in Fiat 1.3 Multijet engines were tested. The injectors were operated on a test rig at room temperature for 500 hours (more than 72 million work cycles). During the test, pressure and injection frequency were changed. Changes in the operating parameters were estimated based on obtained injection characteristics and effective flow area determined thereby. The observed changes in fuel delivery rate were compared with results of the surface analysis of control valves and nozzle needles. Despite the stated lack of wear, significant changes in the dynamics of injector operation were observed, particularly at short injection times. Small pilot injections cannot be corrected by the fuel injection control system because they do not affect the changes in torque; however, they do affect the combustion process. This creates conditions for increased emission of toxic exhaust components.

The purpose of the study was the research concerning the emissions of limited exhaust gas components of the AVL research engine equipped with Common Rail injection system, fuelled with different biodiesel blends and diesel fuel as reference. In details, the engine was powered with mixtures of rapeseed methyl esters (RME) with DF in the volumetric ratios of 10:90, 20:80, 30:70, 40:60 and 50:50. The tests were performed at: 1200, 1700 and 2200 rpm and the torque T = 5…35 Nm (step 5 Nm). The analysis of the obtained results showed that the emissions of hydrocarbons (HC) from the tested engine fuelled with biodiesel are lower than that of diesel fuel. Carbon monoxide (CO) emissions are also lower, except for low rotational speeds and low engine load T = 5…20 Nm. As for nitrogen oxides (NOx) emissions, it is also lower than that for the diesel fuel, except for high engine loads, in the range above 25 Nm, for each rotation speed of the engine load characteristics. Moreover, in this research it was confirmed that emission of particulate matter (PM) is also slightly reduced for the engine fuelled with tested blends.

In this paper authors present the results of their studies on the selection of fuel dose in three-part injection system Common Rail of marine medium-speed combustion engine. The study was conducted on a special test stand, which allows the use of different pressure in the hydraulic tank and various times of injection with doses divided into three parts. Also there has been performed the measurement of single fuel dose mass. The plan of research also included the three values of the two input values (pressure in the hydraulic tank and the total time of injection) and one output - the total mass of the fuel dose. Based on the statistical analysis of measurement results there have been determined the forms of functions approximating the tested relations and have been presented the analysis of the accuracy and their measurements match. Presented polynomials of accuracy (function of researched object) allow a reasonable selection of the basic parameters of dosing for the three-part fuel injection.
W pracy autorzy prezentują wyniki własnych badań dotyczących doboru dawki w trzyczęściowym wtrysku paliwa w układzie Common Rail okrętowego średnioobrotowego silnika spalinowego. Badania przeprowadzono na specjalnym stanowisku badawczym umożliwiającym stosowanie różnych wartości ciśnienia w zasobniku hydraulicznym i różnego czasu wtrysku paliwa przy podziale dawki na trzy części. Wykonywano również pomiar masy pojedynczej dawki. Plan badań obejmował trzy wartości dwóch wielkości wejściowych (ciśnienie w zasobniku hydraulicznym i sumaryczny czas wtrysku paliwa) i jedną wyjściową – całkowitą masę dawki paliwa. Na podstawie analizy statystycznej wyników pomiarów wyznaczono postacie funkcji aproksymujących badane zależności i przedstawiono analizę miar dokładności ich dopasowania. Przedstawione wielomiany dopasowania (funkcje obiektu badań) pozwalają racjonalnie dobrać podstawowe parametry dawkowania dla trzyczęściowego wtrysku paliwa.

Opis:
Article describes the operation issues of contemporary injection systems of Diesel engines. Common-rail system has been used since 1997, and since then there has been a significant evolution in its construction. In this aspect, there are changes in generations of high-pressure injection pumps and fuel injectors as well as methods of steering them, but exploitation problems are the same. The most prone to malfunction elements of the system are the fuel injectors. Their task is to distribute and to spray of the fuel in the combustion chamber of engine. Common Rail fuel injectors generate few injection dosages in the one work cycle. The rate of injection is depended on the design of the steering valve. One very important parameter of fuel injector is fuel injection delay time. If the time from control start of fuel injector to begin injection is shorter then it causes generation of greater number of injection dosages. Pollutants in fuel in the form of various amorphous solids of the size an even few microns cause the decrease of operating parameters of injector, which adversely affects the operation of the engine. Article shows contemporary fuel injectors, the methods of their examination, the types of fuel pollutants and their impact on fuel injector work.

Opis:
The storage supply systems of Common Rail type are characterized by high possibilities in shaping the rate of injection. The possibility to implement multi-injection at high pressure, easiness of adapting the system to the engine, relatively easiness of compensation the arrangement of injector parameters resulting from work tolerance, as well as easiness of making changes in the electronic engine controller enabling the production of engines with various performances, cause that type of these solutions currently are widely used injection systems in diesel engines. Injection system should be characterized above all by high precision fuel dosing into engine cylinders, the accuracy in starts controlling of individual phase of injection, repeatability and reliability and durability, as well as the up keep of these parameters for long time during operating duration. Fuel injection system works in difficult conditions resulting from high pressure, vibrations, electromagnetic interference affecting electronic executive systems and high temperatures. Especially the injector and injection pipes are open to high temperatures. The dimensions of used elements are also important. The article presents selected results concerning the effect of the length of high-pressure pipes on injection process parameters such as fuel amount, overflow in injector, and the fuel pressure course in injection pipe in front of electromagnetic injector socket. The study was conducted with test stand with electronic measurement system of fuel amount. The tests were made at different pressures in the rail and for different durations of the injector opening.
