Opis:
This article characterises the methodology for the endoscopic testing of a laboratory diesel engine used for testing marine fuels. The ‘Shadow’ measurement method used in the XLG3 type EVEREST digital endoscope, for quantitative and qualitative identification of detected surface defects, was approximated. Representative endoscopic images of the elements limiting the working space of the research engine are demonstrated, having been recorded during the usable quality testing of newly produced, low-sulphur marine fuels, so-called ‘modified fuels’. The main purpose of the endoscopic examinations was the final verification of the tested fuel’s suitability for feeding full-size marine engines.

Opis:
The BAT-CELL Bio-Ambient-Tests method is based on the assessment of the influence of the actual toxicity of various types of gas mixtures on living cells, taking into account the additive synergism. Work has been carried out on the application of the BAT-CELL method for testing engine exhaust gases. The application of computational fluid mechanics using Ansys Fluent made it possible to analyse the flow of engine exhaust gases through the aspiration system used, including analysis of shear stress values and their uniformity distribution on the bottom wall of the sampler containing cell culture on the bottom wall of the sampler. The appropriate flow rate of exhaust gases through the aspiration system and the shape of aspiration tubing for the sampler were selected in order to enable uniform contact of gas particles with the cell surface and not to damage them mechanically. The simulation results were verified in real-life tests and confirmed the theoretical assumptions.

Opis:
The implementation of low-sulphur, so-called modified marine fuels into operation requires prior laboratory engine tests to assess the energy, emission and structural effects of their usage. This type of research are carried out on the test bed of a diesel engine as a small-scale physical model that reproduces the adequate design and process (parametric) features of a full-size marine engine. Their key stage is to determine the energy characteristics of the engine in the steady state of operation determined on the basis of the analysis of the developed indicator diagram and the dynamic characteristics of the transient processes from idling to the reference steady state of load - and vice versa. In this way, the basic diagnostic parameters of the fuel usable quality are determined: the rate of pressure increase in the cylinder and the average deceleration of the engine crankshaft within the strenuous transient process. This article presents representative results of this type of research carried out on six different, low-sulphur marine fuels used to feed marine engines.

Opis:
The article describes the methodology of engine tests on new types of low-sulphur marine fuels in laboratory conditions in order to conduct a comprehensive assessment of their suitability for powering full-size marine engines. The innovativeness of the proposed solution consists of adapting the laboratory Diesel Engine Test Bed to carry out experimental tests using residual and alternative fuels so that it is possible to imitate the real operating conditions of the ship engine. The main aim of the research program was to assess the energy efficiency of six different low-sulphur marine fuels and their impact on the chemical emissivity of engine exhaust gases and air pollution with toxic and harmful chemical compounds. In order to achieve the research purpose formulated in this way, it was necessary to: (1) equip the constructed laboratory stand with highly specialised measuring equipment and (2) develop a technology for determining diagnostic parameters representing the basis for developing a ranking of the energy and emission quality of the tested marine fuels according to the proposed physical model. The model distinguishes 10 diagnostic parameters that, after normalisation, form two subsets of evaluation parameters - stimulant and destimulant. Determining their values made it possible to estimate a synthetic variable, according to which all the tested fuels were adjusted in the order from the “best” to the “worst”, in accordance with the adopted qualitative criteria of such an assessment. The results of the laboratory tests show that among the considered fuels, i.e., MDO, MGO, RMD 80/L, RMD 80/S, RME 180, and RMG 380 type, the best solution is to use MDO distillate fuel to power full-size marine engines. However, taking into account its high purchase price, a rational alternative decision is to choose RMG 380 type residual fuel, which ranks second in the ranking of the functional quality of the tested marine fuels.

Opis:
The paper presents the results of model and empirical tests conducted for a marine diesel engine fueled by a blend of n-butanol and diesel oil. The research were aimed at assessing the usefulness of the proprietary diesel engine model in conducting research on marine engines powered by alternative fuels to fossil fuels. The authors defined the measures of adequacy. On their basis, they assessed the adequacy of the mathematical model used. The analysis of the results of the conducted research showed that the developed mathematical model is sufficiently adequate. Therefore, both the mathematical model and the computer program based on it will be used in further work on supplying marine engines with mixtures of diesel oil and biocomponents.

Opis:
This paper describes the results of an engine study of the tendency for fuel injector deposits to form by gasolines of various compositions. Since the factors promoting the formation of fuel injector deposits in DISI engines have, in many cases, been insufficiently identified they require further research and investigation work, which was the greatest motivation for undertaking this project. The latest CEC F-113-KC test procedure for the most damaging deposits in DISI engine injectors was used for this purpose. The research results obtained in the framework of the conducted project indicated T90, aromatic and olefinic hydrocarbons, sulphur, ethanol, DVPE, IBP and fuel density as the most important factors causing the increase in the tendency for deposits to form on the injectors of SI type DISI engines.

Opis:
The article briefly describes the problem of air pollution caused by sea-going ships and the resulting restrictions on the emission of toxic and harmful chemical compounds in the exhaust of marine engines, introduced by the International Maritime Organization (IMO) under the International Convention for the Prevention of Sea Pollution from Ships (MARPOL 73/78). Such emissions provide a significant metrological problem, not only for the owners of operating seagoing ships, but also for shipyards, maritime administration offices and environmental protection inspectors. For this reason, the article’s author is developing research issues related to the diagnosing the exhaust emissions of marine engines under operating conditions, i.e. with limited control (measurement) susceptibility. This is particularly important in the period of intensive implementation of a new category of marine fuel, so-called modified fuels with low sulphur content. As part of the problem, a computational model of the parameters characterising the exhaust emissions of a marine engine in operation is presented in this article. This model is based on the measurement of the engine’s control parameters, using a standard (stationary) measurement system and a portable diagnostic system, configured for the purpose of this research. Presented here are representative measurements and calculation results (both obtained by the author and provided by the manufacturer) from the chemical exhaust gas emissivity of one of the ship engines operated. These confirm the adequacy of the calculation model developed and the diagnostic effectiveness of the measuring equipment applied. The methodology developed for experimental testing may also be implemented for the operation of other types of marine engines, provided that the basic chemical composition of the fuel supply and the engine load characteristics and hourly fuel consumption are known. Moreover, there is the possibility of indicating the cylinders and measuring the chemical composition of exhaust gases in the high-temperature part of the exhaust duct.

Opis:
The subject of the article is a synthetic lubricant for the latest generation internal combustion engines, used especially in passenger cars, equipped with both spark ignition engines and compression ignition engines, which is used in particular in passenger cars operating in urban conditions, overcoming relatively short distances, and therefore working usually below the recommended operating temperature of the engine. The developed 5W30 oil maintains excellent rheological properties (fluidity) also before reaching the correct operating temperature of the engine, especially at negative temperatures, which results in lower oil pump resistance and reduced friction of key engine components, which ensures better engine working conditions and affects its service life.
Przedmiotem artykułu jest syntetyczny preparat smarowy do silników spalinowych najnowszych generacji, stosowanych zwłaszcza w samochodach osobowych, wyposażonych zarówno w silniki o zapłonie iskrowym, jak i w silniki o zapłonie samoczynnym, mający zastosowanie w szczególności w samochodach osobowych poruszających się w warunkach miejskich, pokonujących stosunkowo krótkie odległości i z tego powodu pracujących zazwyczaj poniżej zalecanej temperatury roboczej silnika Opracowany olej 5W30 zachowuje doskonałe własności reologiczne (płynność) także przed osiągnięciem właściwej temperatury pracy silnika, zwłaszcza w ujemnych temperaturach, co powoduje mniejsze opory dla pompy olejowej oraz zmniejszenie tarcia kluczowych elementów silnika, co zapewnia lepsze warunki pracy silnika i wpływa na jego żywotność.

Opis:
The temperature of the exhaust gas of a diesel piston engine, measured in the characteristic control sections of its thermo-flow system, can be a valuable source of diagnostic information about the technical condition of the elements limiting the working spaces thus separated, including the turbocharging system, but also its fuel supply system and replacement of the medium. In standard marine engine measurement systems equipped with an impulse turbocharging system, the exhaust gas temperature is measured at the outlet of individual cylinders and before and after the turbocharger turbine, using traditional thermocouples with high measurement inertia (time constant of tenths of a second and more). This means that for further diagnostic analyses, the average value of the periodically changing temperature of the exhaust stream leaving individual engine cylinders, the exhaust stream in the collective duct feeding the turbine and the exhaust stream in the exhaust duct of the turbine is used. This article proposes a new approach to the issue of diagnostic informationiveness of the exhaust gas temperature of a diesel engine, extending its observations with the dynamics of changes in the duration of one working cycle. The aim of the tests carried out on the laboratory stand of Farymann Diesel engine type D10 was to determine the diagnostic relations between the loss of permeability of the inlet air channel filter baffle and selected standards of the quick-changing signal of the exhaust gas temperature. On the basis of the calculations carried out, the following dynamic features of the recorded signal were determined: maximum amplitude of instantaneous exhaust gas temperature values (peak-to-peak value), its rate of increase and decrease, and the specific enthalpy of exhaust gases within one engine work cycle. Comparative analysis of numerical data characterizing the recorded quick-changing exhaust gas temperature courses clearly indicates obvious thermodynamic and energy consequences of partial loss of flow capacity of the air channel supplying the combustion chamber of the test engine. A further development of the experimental test programme is foreseen in order to determine a diagnostic matrix to support the diagnostic inference about the technical condition of the diesel engine on the basis of measurements and analysis of the quick-changing exhaust gas temperature.

Opis:
Within the article an issues of implementing the new kinds of marine diesel fuels into ships’ operation was described taking into account restrictions on the permissible sulphur content introduced by the International Maritime Organization. This is a new situation for ship owners and fuel producers, which forces the necessity to carry out laboratory research tests on especially adapted engine stands. How to elaborate the method enabling quality assessment of the self-ignition engine performance, considered in three categories: energy, emission and reliability, represents the key issue of the organization of such research. In the field of energy research, it is necessary to know the thermal efficiency of the engine as the basic comparative parameter applied in diagnostic analyzes and syntheses of sequentially tested marine diesel fuels. This type of scientific research has been worked out for two years in the Department of Marine and Land Power Plants of the Gdańsk University of Technology, as a part of the statutory activities conducted in cooperation with the Regional Fund for Environmental Protection in Gdansk and the LOTOS Group oil company. This article presents the algorithm and results of thermal efficiency calculations of the Farymann Diesel D10 test engine in the conditions of feeding with various low-sulfur marine diesel fuels: distillation and residual fuels. This parameters stands for one of ten diagnostic measures of the ranking of energy and emission quality of newly manufactured marine diesel fuels being built at the Department.

This work presents selected results of I-31T propulsion flight tests, obtained in the framework of ESPOSA (Efficient Systems and Propulsion for Small Aircraft) project. I-31T test platform was equipped with TP100, a 180 kW turboprop engine. Engine installation design include reverse flow inlet and separator, controlled from the cockpit, that limited ingestion of solid particulates during ground operations. The flight tests verified proper air feed to the engine with the separator turned on and off. The carried out investigation of the intake system excluded possibility of hazardous engine operation, such as compressor stall, surge or flameout and potential airflow disturbance causing damaging vibration of the engine body. Finally, we present evaluation of total power losses associated with engine integration with the airframe.

Samolot I-31T jako platforma badawcza był wyposażony w silnik turbośmigłowy typu TP100 o mocy startowej 180 kW. Projekt zabudowy silnika uwzględniał wlot powietrza o odwróconym przepływie i sterowany z kabiny separator ograniczający do minimum pochłanianie przez silnik obcych ciał podczas operowania samolotu na ziemi. Omawiane próby w locie miały na celu sprawdzenie prawidłowości zasilania silnika powietrzem poprzez układ wlotowy z separatorem wyłączonym i włączonym. Przeprowadzone badania układu wlotowy wykluczyły wystąpienie niebezpiecznych charakterystyk użytkowania silnika takich jak: przeciągniecie sprężarki, pompaż czy gaśnięcie oraz potencjalne zaburzenia przepływu powietrza w układzie, mogące powodować powstawanie szkodliwych drgań korpusu silnika. Przytoczono także wyniki oceny sumarycznych strat mocy silnika związanych z jego zabudową na płatowcu.

The paper presents an analysis of the possibility of determining the general characteristics using the operational data of an engine of refuse collection vehicle. Data acquisition was done by reading information from the CAN network using FMS standard (Fleet Management System), which is widely used in heavy duty vehicles since year 2002. The paper presents the analysis of the expected measurement uncertainties resulting from the standard PN_ISO 15550-2009. The experimental data were filtered due to the established constraints that define the static states of the engine. On the basis of the obtained measurement data, corresponding to various defined static states, the general characteristics of the engine were made and discussed.

Opis:
The contemporary progress of automotive industry and transportation is determined to a large extent by the increasing environmental requirements, aimed at limiting the harmful impact of vehicles upon human life and people’s health. A crucial issue linked with operating vehicles is the exhaust gases generated by internal combustion engines. In order to reduce this hazardous impact upon the natural environment, the construction of the engines is continuously improved, electronic controlling is being developed for managing the course of working processes taking place in cylinders and auxiliary systems, exhaust gases cleaning systems are being developed, alternative fuels are being sought for and the possibilities of their optimal use are being examined. Natural gas is the fuel that is highly expected and hoped to be used more widely for powering internal combustion engines in vehicles. This article presents the values of selected ecological indicators of the Perkins 1104D-E44TA Diesel engine, powered by compressed natural gas and Diesel fuel (CNG + ON). For comparison reasons, the engine was powered with both fuels at the same time and then only by Diesel fuel (ON) in the same working conditions. Before the tests, the powering system control unit had been calibrated so as to enable obtaining similar values of torque while the engine was powered with the Diesel fuel only and with both CNG and ON while working with external speed characteristics; the calibration was also set up to allow for the maximum share of the natural gas in the total fuel amount supplied into the engine cylinders without engine knocking. When powering the engine with both CNG and Diesel fuel, the concentration levels of nitric oxides and carbon dioxide in exhaust gases were lower. However, the total content of hydrocarbons in the exhaust gases grew multiple times, and the content of the carbon monoxide was significantly increased. In addition, the obtained measurement results of the smokiness of the exhaust gases and the content of the soot with the engine powered with two fuels were not satisfactory.
