Opis:
The study examines the effect of transformation ratio in power transmission system on engine efficiency as a function of passenger vehicle velocity (m = 1400 kg) with energy-saving vehicle drive. The study also presents working range in driving phases for energy-saving speed control up to 120 km/h for a simplified overall engine performance map for SI engine. Understanding of the presented considerations can be facilitated through relating with advantages of application of non-driving phases in low engine load phases (field 4 in overall engine performance map). Working points of SI engines in engine performance maps were divided in terms of energy-saving vehicle speed control into 4 ranges. Zone l is the most economic whereas zones 3 and 4 are the least energy-saving, which was also discussed by the author in other works. The study presents the location of engine working points in overall engine performance map during energy-saving vehicle speed control within the range of 30-120 km/h using two different 6-gear gearboxes. Working range for CI engine in simplified overall characteristics in truck, the impact of speed control upon fuel consumption in real traffic conditions, sum and difference characteristics of components of drive engine unitary power, area of maximal rise in overall engine efficiency after reduction of rotational speed, simplified SI engine performance maps, covering with economic zone of working point in energy-saving drive of vehicles are presented in the paper.

Opis:
Measuring method and calculations of the impact of non-stationary work conditions of car engine torque load upon its effective efficiency have been presented in the paper. The obtained results have been compared to the already achieved results. The applied method of calculation balance and the consumed fuel enabled the writer of the paper to calculate the value of the change of unitary fuel consumption at a work point on engine performance map. The carried out examinations focus on measurements at one measuring length and so the rate of torque load at each of the four gear box ratio (2-5) can be controlled by constant final velocity of driving or by shifting or extending the measuring length against the lowest point ( the measuring length is 'U'-shaped). Finding the right solution to this problem will allow elaborating the calculation algorithm of engine effective efficiency for the examined range of engine performance maps for changeable, non-stationary work conditions. The results make it ąuite explicit that non-stationary work conditions from the engine speed and the engine load impair the effective efficiency of the engine at work in particular gears. Non-stationary mode of engine operation is essential for the higher values of gear box ratio whereas for lower values the engine load really matters.

Opis:
The article presents theoretical research of the proposed system of fully independent valve control (FIVC) of the SI engine. The analysis included controlling the movement of the intake valves, which results in adjusting the mass of the fresh charge to the current engine load, as well as the movement of the exhaust valves, where the main aim is to keep the rest of the exhaust gas in the cylinder, i.e. implementation of internal EGR. The open theoretical Seiliger-Sabathe cycle with the classic throttle regulation of load is the reference cycle for assessment of benefits and study of the effectiveness of obtaining work as a result of application of the FIVC system. A comparative analysis of the effectiveness of application of the proposed system was carried out based on the selected quantities: fuel dose, cycle work, relative work of charge exchange and cycle efficiency. The use of the FIVC to regulate the SI engine load makes it possible to eliminate the throttle and thus reduce the charge exchange work, especially in the partial load range. And this then leads to an increase in internal and effective work, which in turn results in an increase in the effective energy efficiency of an engine operation.

Opis:
A method is proposed in the paper to calculate effective efficiency of an engine in nonstationary operating conditions. A reference point for this method is the effective efficiency of the engine derived from its performance map. A research methodology has been developed to this end, the basis of which consists of measurements and calculations of the to tal energy efficiency of a car motion in a variable driving cycle. In order to determine the impact of the road grade, measurements were performed along a geodetically described roadsection in two traffic directions: "up " and "down ". The adopted research scheme allows covering the area of the engine performance map being of interest to us with measuring points. The mean value or rotational speed and its change in unit oftime were adopted as the leading parameters which have a dominating influence on, and result in a reduction of the effective efficiency of the engine. To improve the accuracy of calculations, the variable driving cycle consists of driving phases and idle running. The volume of fuel consumed, not accounted for in the driving phases, being the difference between the calculated and consumed fuel, is a measure of reduction of the effective efficiency of the engine, whilst the unit power of additional motion resistance of the vehicle (a*ni) is a leading parameter in the analyses of the calculation results.

Opis:
The aim of the article is to analyze the impact of effective time management on the performance of workstations in the context of the conflict between maximizing workstation utilization and minimizing the number of items waiting in the queue. The article utilized the FlexSim program to build a simulation model of the workstation and conducted optimization using the built-in optimizer. The research demonstrated that effective time management has a positive impact on workstation performance by reducing the number of items waiting in the queue, leading to increased throughput and reduced delays in production processes. An important aspect of the analysis was the application of a multi-criteria optimization approach, which allowed for achieving a balance between maximizing workstation utilization and minimizing the number of items waiting. Multi-criteria optimization considers diverse goals and decision criteria, leading to a more comprehensive approach to optimizing production processes. As a result, effective time management on workstations, based on analysis and multi-criteria optimization, can significantly improve the efficiency and performance of production processes. This analysis can be a valuable tool for organizations seeking to optimize their processes and achieve a competitive advantage in the market. The analysis conducted in the article confirms that effective time management has a beneficial impact on workstation performance. The use of a multi-criteria approach in optimization enables achieving a balance between various decision factors. The presented simulation model and research results can be useful for decision-makers in the manufacturing field who aim to make more informed decisions regarding planning and optimizing production processes to enhance efficiency, effectiveness, and customer satisfaction.

Opis:
In this work, we propose a new method for manufacturing busbars in photovoltaic modules for different solar cell generations, focusing on 1st and 3rd generations. The method is based on high-pressure spray coating using nanometric metallic powder. Our focus is primarily on optimizing conductive paths for applications involving conductive layers used in 3rd generation solar cells, such as quantum dot solar cell, dye-sensitized solar cell, and silicon-based solar cells on glass-glass architecture for buildingintegrated photovoltaic. The advantages of the proposed method include the possibility of reducing the material quantity in the conductive paths and creating various shapes on the surface, including bent substrates. This paper examines the influence of the proposed high-pressure spraying technique using metallic particles on the morphology of the resulting conductive paths, interface characteristics, and electrical parameters. Conductive paths were created on four different layers commonly used in photovoltaic systems, including transparent conductive oxide, Cu, Ti, and atomic layer deposition processed Al2O3. The use of high-pressure technology enables the production of conductive layers with strong adhesion to the substrate and precise control of the spatial parameters of conductive paths. Furthermore, the temperature recorded during the deposition process does not exceed 385 K, making this technique suitable for various types of substrates, including glass and silicon. Additionally, the produced layers exhibit low resistance, measuring less than 0.3 Ω. Finally, the mechanical resistance, as determined through tearing tests, as well as environmental and time stability, have been confirmed for the produced paths.

Opis:
The possibilities of introducing new institutions to help overcome the current dysfunctions of the global financial market are analysed in the article. First of all, the monitoring and regulation institutions proposed by, George A. Akerloff, Paul Krugman, Joseph E. Stiglitz, Nouriel Roubini and Robert J. Shiller were discussed. In turn, the new concept of a progressive global tax on capital by Thomas Piketty is presented. The concept proposed by Piketty is the most radical one, and it should be associated with the greatest hopes. However, implementing it on a global scale seems to be extraordinary difficult due to the lack of uniform political will to introduce an automatic, global exchange of information between banks.
W artykule przedstawiono analizę możliwości wprowadzenia nowych instytucji warunkujących przezwyciężenie obecnych dysfunkcji globalnego rynku finansowego. Na początku omówiono instytucje monitorujące i regulujące zaproponowane przez amerykańskich laureatów Nagrody Nobla. W drugiej kolejności przedstawiono nową koncepcję globalnego progresywnego podatku od kapitału Thomasa Piketty. Koncepcja, zaproponowana przez francuskiego ekonomistę, jest najbardziej radykalna i z nią powinny być wiązane największe nadzieje. Jednak wdrożenie jej na skalę globalną wydaje się wyjątkowo trudne ze względu na brak jednolitej woli politycznej wprowadzenia w skali globalnej bezwarunkowej, automatycznej wymiany informacji międzybankowej.

Opis:
The article presents an analysis of changes in the tax efficiency of companies listed on the Warsaw Stock Exchange. After 2017, some changes to the tax law aimed at tightening the regulations on an unprecedented scale were introduced. The research conducted showed that since 2018 there has been a decrease in tax efficiency measured with effective tax rate (ETR) and current effective tax rate (CETR). On average, in 2018–2019, the efficiency measured with CETR dropped by 17.7%, the median by 14.8% compared to the previous years. In 2018 and 2019, the value of the CETR was the highest in the entire analyzed period, i.e. from 2012 to 2019. At the same time, the propensity of companies to create deferred tax assets is declining, and the effective tax rate is also growing. The changes mainly concern companies with average tax efficiency, large entities forming capital groups, and companies implementing capital investments. The article presents a discussion on the observed trends and formulates directions for further research.

The article describes the processes that take place in an engine. The main terms connected with the compression ratio are explained. Moreover, the relationship between the compression ratio and the engine efficiency is discussed. This paper is a repetition of issues connected with functioning of the engine. In this article, variables that influence the chart are described, along with some examples of the way to increase engine efficiency. This article focuses on selected methods of improving efficiency of internal combustion engines. In order to fully understand processes taking place in the combustion chamber, it is necessary to create theoretical charts of thermal cycles and, then, to compare them with actual charts obtained as a result of measurements. The structure of contemporary engines is influenced by various factors, for example preservation of natural environment or limited fuel resources. These factors are crucial for mechanical engineering and engine design. Therefore, energy consumption and environmental impact of engines are taken into consideration when researching new ways and methods of enhancing engine efficiency. One of the main aims of the researchers and engineers is to reduce the emission of carbon dioxide (CO2), carbon monoxide (CO), hydrocarbons (HC) and oxides of nitrogen (NOx) in exhaust fumes. Improved engine efficiency, lowered fuel consumption and reduced emission of toxic substances are the main advantages of internal combustion engines characterized by variable compression ratio.

Opis:
Supply chain can be considered as a series of linked inventories. This paper considers the impact of inventory on the economics of the businesses and the whole chain and discusses causes of inefficiency. In most supply chains the goods are inactive for the majority of the time, and this leads to longer term and therefore less accurate forecasting. The result is typically excess inventory, shortages, and inflexibility. By analysing the wasted time and costs in the supply chain, a clearer view of the whole process can be created. Total supply time can be considered as three components, namely value added time, non-value added process time, and waste time. This basic approach shows where improvements should be focussed. Using this time-based measurement enables more relevant comparison between supply chains than the normal supply chain efficiency ratio.
