Opis:: The paper deals with new construction of low pressure cylinder (LPC) for condensing steam turbines. The flow path of these cylinders is formed on the base of new two-tier stages. As opposed to well known Baumann’s stages newer two-tier stages is a combination of two independent stages with own blades set. Such construction allows to decrease the number of LPC in the existing turbines or to ensure their operation with very high vacuum in the condenser or increases in 1.5 times power capacity of new turbines without increasing of the last stage blade length and LPC number.

Opis:: The results of the gas-dynamic calculation of the low-pressure cylinder flow part of the K-220-44 type steam turbine intended for operation at nuclear power plants are presented. The ways of the flow part improvement were determined. Some of those ways include the use of innovative approaches that were not previously used in steam turbines. The design of the new flow part was carried out on the basis of a comprehensive methodology implemented in the IPMFlow software package. The methodology includes gas-dynamic calculations of various levels of complexity, as well as methods for analytical construction of the spatial shape of the blade tracts based on a limited number of parameterized values. The real thermodynamic properties of water and steam were taken into account in 3D calculations of turbulent flows. At the final step, end-to-end 3D calculations of the lowpressure cylinder that consists of 5 stages were performed. The technology of parallel computing was applied in those calculations. It is shown that due to the application of innovative solutions, a significant increase in efficiency can be achieved in the developed low-pressure cylinder.

Opis:: The paper discusses issues related to measurement of unsteady angular speed of diesel engine crankshaft. The focus is on the selection and optimization of the measuring method to obtain high accuracy, eliminating errors resulting from the unsteady angular speed of markers on diesel engine crankshaft. A method that uses a counter markers placed on the engine flywheel had been worked out. Markers location has been read out by two slit optical sensors. Number of markers and the distance between the sensors were chosen so as to counter tooth during the transition between the sensors count the more than 10,000 pulses at rated speed of the shaft. This provided a measurement method resolution at 0.01 %. Initial studies were performed on one-cylinder diesel engine with the greatest unsteady of angular speed. Additionally analysis which treated the measured unsteady angular speed of diesel engine crankshaft as a deforming pressure mapping as a function of the calculated piston movement was performed. This deformation is caused by the assumption that a constant rotation speed is proportional to time, and measurements are made at a constant rate. In the case of synchronized measurements of PLL circuits duplicating markers on the shaft against the expectations the deformations due to the activity of the follow-up mode of such systems are increased. The influence of these deformations on the designation of an average error of cylinder indicated pressure and other parameters obtained from the analysis of the pressure and vibration envelope has been examined.

Opis:: In this paper the experimental results of spark ignited (SI) engine fuelled with lean mixture of simulated producer gas compared with chosen gaseous fuels are presented. The SI engine test fuelled with simulated producer gas, natural gas and simulated biogas with variable value of excess air ratio has been done. The experiments were carried out on the petrol engine with a low engine displacement. Typical SI engine was selected in order to evaluate the potential application of gaseous fuel (i.e. producer gas, natural gas or biogas). These types of engines are available on a wide scale and commonly used in automotive sector because of the low purchase price and operating costs. It is expected that after minor modifications, the engine can easily operate in micro CHP system. The main goal of this work is to determine the performance of the engine and its impact on the environment during the combustion of the lean producer gas mixtures. The study shows the impact of both the excess air ratio and the type of fuel used for engine performance and emission index. Combustion of lean mixtures of producer gas leads to an increase of carbon monoxide in the exhaust. Increasing the value of excess air ratio affects the growth of indicated efficiency of the engine

Opis:: The paper characterises the current state of development and use of equipment and monitoring-diagnostic systems of engine cylinders and reciprocating compressors. It has presented a prototype system for monitoring and diagnostics of motor compressors of GMVH type natural gas installed in the Krio Company in Odolanów. The system monitors on-line 5 stands of motor compressors. Simultaneously 12 engine cylinders and 6 compressor cylinders of each motor compressor are indicated - a total of 90 cylinders. Driven by the need to reduce the number of monitors in the control room, aprinciple to operate the system through one monitor with the capability of immediate switching-off of a monitored motor compressor has been adopted. A charts menu provides for simultaneous on-line observation of the work of all the cylinders of a selected motor compressor. For each cylinder of both engine and compressor, against the background of the average from 16 runs and average for the cylinder's unit there are presented a few indicator diagrams, which allows for observation of the variability of a cylinder 's work, which in a spark-ignition engines can be significant. Values of main parameters ofthe cylinder's work are presented in tables and bar charts. These include: the maximum pressure of combustion and compression as well as average indicated pressures. The indicated powers are determined for the engine and compressors and a mechanical efficiency of the unit. The fiber-optic "Optrand" sensors have been used for indication, mainly to meet the need of spark-safety requirements. For the measurement of pressure, 12-bit converter cards ofown construction have been applied. Values of pressure have been sampled with angle axis pulses 0.5° crankshaft rotation. Ethernet connections were applied to transfer data between the pumping station and control room. The study characterises the main conclusions arising from past experience of system use.

Opis:: In this paper the calculations algorithm of heat-transfer coefficient in the combustion chamber of the internal combustion engine is presented. Developed algorithm is based on the in cylinder pressure data. The proposed algorithm can be helpful to determine the average values of heat-transfer coefficient from working medium to the combustion chamber walls (crown of a cylinder head, cylinder walls and piston head) during combustion process. The calculation method includes modified one zone heat release model in combustion chamber of SI engine. Proposed method consists in closing the energy balance equation by the coefficient which expresses the heat losses to the walls of the combustion chamber. The average value of the heat losses during combustion process is calculated by two steps. Firstly, the integration of the energy balance equation (without specifying the heat losses) leads to designation of the so-called net value of heat released in cylinder. In the next step the amount of the total energy supplied to the cylinder is determined taking into account the chemical energy of the supplied fuel. The difference between the supplied value of chemical energy and heat released net value allows to determine the heat losses average value. In last stage, the heat flow equation leads to calculate the mean value of heat transfer coefficient during combustion process.

Opis:: The practical design of the marine engine multi in-cylinder pressure acquisition system has been presented. The system operational properties and measurement methodology is aimed the online marine diesel engine applications. The design of engine combustion pressure recording system is based on piezoelectric sensors set that comprises quartz pressure element and charge amplifier, mounted on the indicator pipes, equipped with valves. The required crank degree signal is obtained from shaft encoder that is installed on the test bed engine shaft-line (free end of the hydraulic break). The encoder's TDC dedicated reference pulse is able generate simultaneously at the cylinder 1 and 6 in TDC position. The accuracy of the static crankshaft position calibration was evaluated. Additionally, a complex timing system was developed for individual cylinder TDC and crankshaft positioning definition. Before real time data acquisition starts, the number of engine cycles is defined for recording and the first pulse of each crankshaft revolution is used as trigger signal, so that all instantaneous pressure and crank angle signals acquisition can be started at the identical crankshaft position. The method provides required numbers of combustion cycles to be measured for time domain averaging and off line processing.

Opis:: Control of diesel fuel injection is very important and has influence not only at engine operating conditions but also at emission of toxic gases as NOx, HC, and Particulate Matter (PM) are effect of combustion process. Directly observing of combustion process is very difficult, but implementation to injection control algorithm procedures based on additional sensors as knock sensor, cylinder pressure sensor and observing of rotational speed course could give enough information to optimize control algorithm. In traditional diffusion-burn diesel combustion start of combustion occurs a cetane-number based time delay after the start of the fuel injection. To fulfill of new emission standards is need to observing not only start of combustion but also whole combustion process. In the paper conception of injection control system applied with combustion process observer based on additional sensors. Closed-loop feedback control of cylinder pressure sensor and advanced control algorithm with high-resolution rotational speed sensor offers the potential to improve controllability of combustion process. Advanced control system based on heat release estimated from cylinder pressure and rotational speed fluctuations enabling improving engine exhaust emissions, engine performance and reduced noise emission. Introducing into control system a low cost glow plug integrated cylinder pressure sensor allow to achieve complete injection control system with advanced functions which could be very effective also in aspect of fuel consumption reduction.

Opis:: The article presents problems occurring during the signals processing of the parameters of working processes of internal combustion engines in tests, while powering the measuring apparatus from the electric network of the marine power plant laboratory. Various experimental methods of separation were used to identify and then eliminate interference. On the basis of analyses carried out in the domain of time and frequency of the in-cylinders pressure signals of internal combustion engines and their wavelet decomposition, attempts were made to determine and eliminate the sources of interference. It has been shown that interference was penetrating the measuring equipment through the supply network. The developed methods of reducing interference in the laboratory conditions can be applied on the marine vessels. On the basis of the conducted tests, it can be concluded that the reduction of interference of pressure measurement signals in the engine cylinder is most effective when the computer is powered only from the battery while the measuring circuit is powered directly from the power network.
W artykule przedstawiono problemy występujące w czasie przetwarzania sygnałów parametrów procesów roboczych w badaniach silników spalinowych, przy zasilaniu aparatury pomiarowej z sieci elektrycznej laboratorium siłowni okrętowej. Dla identyfikacji i następnie eliminacji zakłóceń zastosowano różne eksperymentalne metody ich separacji. Na podstawie wykonanych analiz w dziedzinie czasu i częstotliwości sygnałów ciśnienia w cylindrach silników spalinowych oraz ich dekompozycji falkowych próbowano ustalić źródła zakłóceń oraz je eliminować. Wykazano, że zakłócenia przedostają się do aparatury pomiarowej przez sieć zasilającą. Wypracowane sposoby redukcji zakłóceń w warunkach laboratoryjnych mogą być zastosowane na statkach morskich. Na podstawie przeprowadzonych badań można stwierdzić, że redukcja zakłóceń sygnałów pomiarowych ciśnienia w cylindrze silnika jest najskuteczniejsza, gdy komputer zasilany jest tylko z baterii, a tor pomiarowy bezpośrednio z sieci elektroenergetycznej.
