W pracy zaprezentowano model układu napędowego pojazdu z silnikiem o ZS i przekładnią automatyczną wyposażoną w przekładnię hydrokinetyczną. Model symulacyjny wykonany został przy użyciu programu MatLab Simulink R2009a. Przedstawiono jego główne podsystemy oraz koncepcję układu sterowania mające decydujący wpływ na prace układu napędowego. W zaproponowanym modelu symulacyjnym położenie pedału przyśpieszenia jest informacją o woli kierowcy, o zadanej prędkości pojazdu i sposobie jej osiągnięcia (jazda dynamiczna, ekonomiczna), czyli wyborze strategii jazdy. Obecne uwarunkowania ekologiczne tj. normy EURO 3,4,5, wymagają by odpowiadające im strategie jazdy były realizowane ekologiczne. Decyzja o wyborze przełożenia i stopniu obciążenia silnika jest podejmowana w sterowniku nadrzędnym, poza kierowcą, pozwalając ostatecznie na ekonomiczną, ekologiczną lub dynamiczną prace całego układu napędowego. W końcowej części pracy zostały poddane analizie wyniki badań symulacyjnych.

Opis:
W artykule przedstawiono wyniki badań silników z zapłonem samoczynnym, przeprowadzonych na hamowni inercyjnej. Badania wykazały, że silnik typu Y22DTR charakteryzuje się wyższą mocą oraz momentem obrotowym niż silnik typu AFN. Pomimo wyższego momentu obrotowego silnik Y22DTR posiada mniej korzystny zakres prędkości obrotowej wału korbowego, dla której moment obrotowy osiąga wartości zbliżone do maksymalnych. Uzyskane wyniki świadczą o tym, że układ korbowo-tłokowy silnika Y22DTR z uwagi na większy moment obrotowy i moc jest obciążony większymi siłami niż silnik AFN.
The article presents results of tests for self-ignition engines, carried out in inertial engine test house. The research has shown that Y22DTR type engine has more horsepower and higher torque than AFN type engine. In spite of higher torque, the Y22DTR engine offers less favourable range of crankshaft rotational speed, for which torque reaches values close to maximum. The results show that due to higher torque and horsepower, the assembly of crankshaft, pistons and connecting rods in the Y22DTR engine is subject to higher forces than the AFN engine.

Opis:
The article discusses methods for determining top dead center, based on the analysis of pressure diagrams of a marine engine. The advantages and disadvantages of different methods are shown. Diagnostics of marine engines during operation and the selection of optimal operating conditions is based on the analysis of gas pressure diagrams, as well as fuel supply and gas distribution diagrams. As a result of the analysis of the pressure diagrams, the indicator engine power is calculated, which is further used in the management of engine operation modes, in the calculation of specific indicators, as well as in the calculation of energy efficiency coefficients of marine vessels according to International Maritime Organization recommendations. The influence of the accuracy of determining the position of the top dead center on the calculation of the mean indicated pressure and indicator power is shown. The authors considered a method for determining top dead center, based on the solution of the equation P’= 0, which provides the required accuracy in calculating the mean indicated pressure and indicator power of the engine during operation. It is shown that the method can be applicable in marine engine working process monitoring systems as an alternative to hardware methods for determining the top dead center.

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.

During ship operation, one of the most important tasks is forecasting the ocean route. One of the criteria for forecasting is the minimum fuel consumption. Fuel consumption and associated emissions are also very important for other criteria. In common use, as well as in various publications, the results of calculations of fuel consumption obtained from simplified algorithms are presented. The article presents a mathematical model for calculating fuel consumption for a floating vessel in various weather conditions. In this model different criteria for controlling the propulsion engine were used by changing the fuel dose. The results of the calculations included include: fuel consumption, power of the propulsion engine and operating speed of the ship in varying weather conditions

Opis:
The study is devoted to the possibility of increasing the efficiency of the working process in dual-fuel combustion chambers of gas turbine engines for FPSO vessels. For the first time, it is proposed to use the advantages of plasma‒chemical intensification of the combustion of hydrocarbon fuels in the dual-fuel combustion chambers, which can simultaneously operate on gaseous and liquid fuels. A design scheme of a combustion chamber with a plasma‒chemical element is proposed. A continuous type mathematical model of a combustion chamber with a plasma‒chemical element has been developed, which is based on the solution of a system of differential equations describing the processes of chemical reactions in a turbulent system, taking into consideration the initiating effect of the products of plasma‒chemical reactions on the processes of flame propagation. A modified six-stage kinetic scheme of hydrocarbon oxidation was used to simultaneously predict the combustion characteristics of the gaseous and liquid fuels, taking into account the decrease in the activation energy of carbon monoxide oxidation reactions when the products of the plasma‒chemical element are added. The results reveal that the addition of plasma‒chemical products significantly reduces CO emissions in the outlet section of the flame tube (from 25‒28 ppm to 3.9‒4.6 ppm), while the emission of nitrogen oxides remains practically unchanged for the studied combustion chamber. Further research directions are proposed to enhance the working process efficiency of a dual-fuel combustion chamber for gas turbine engines as part of the power plant of FSPO vessels.

In a conventional internal combustion engine, only electrical controls are used to prepare the fuel mixture. All parts must operate flawlessly in order for the vehicle and its components to operate correctly. Road safety may be negatively impacted by the failure of specific components. The purpose of the study was to ascertain how much the malfunction of particular electrical components affects how the vehicle operates. The vehicle’s individual electronic parts were removed, and the engine power was then assessed. The primary determinant of a vehicle’s technical condition is thought to be its engine power. The preparation of the combustion mixture was affected by the individual component disconnections, which reduced the vehicle’s performance. A vehicle with an in-line four-cylinder engine was used for the experiment, which was conducted in a lab setting. This vehicle’s eight components were gradually disengaged. The change in engine power was observed while they were disconnected. The measured values were always evaluated in terms of an automobile that had no defects and was in excellent condition. The study’s findings demonstrate that there are circumstances in which a vehicle’s usual operation is adversely affected when one or more of its electrical components malfunctions.

Opis:
Power of any kind of a car engine is considered to be one of the basic factors in order to choose or assess vehicles equipment or its appropriateness. It influences several operation properties including car maximum velocity, car acceleration, etc. A car producer shall issue the data about an engine power of a car in a form of its technical attributes, nevertheless an engine power specification is also stated in a car registration certificate. Engine power may be defined as the maximum engine output at given revolutions of an engine, i.e. maximum engine power. In most of cases of cars operation, various situations may occur in order to specify the maximum engine power value. This study addresses the issue of determining individual factors affecting the engine power while a passenger car in operation, i.e. testing the engine power on the single roller bench and related particular analysis.

Opis:
Operation of ship propulsion system is associated with realization of definite operational goals. If to elements of the system the operational reliability strategy could be applied, the situation would be very simple as existing conditions would unambiguously determine application of means being on hand. However decision to reject application of the strategy (even if hypothetical) becomes obvious with a view of necessity of ensuring an acceptable level of safety to ship and environment as well as presence of associated formal and legal limitations. Therefore complexity of operational reality makes that means intended for operation may be used in various ways. Objectivity and rationality in making decision, assumed optimal in given conditions, forces to apply an evaluating (quantitative) approach to the problem, hence to search for such their parameters (indices) which, in a given decision situation, can be deemed most adequate. To precisely determine the task it is necessary to specify also its duration time, apart from conditions in which it will be realized. When considering propulsion engine, i.e. the main element of ship propulsion system, especially important becomes not only the problem which amount of energy could be at one's disposal but also within which time interval it could be delivered. Therefore apart from applying the commonly used reliability indices, it seems sensible to consider the operation in such evaluating approach as it could be determined by energy and time simultaneously.

This paper presents a development of the known qualitative method for assessment of engine operation, applied to ship main diesel engine as an example. According to this interpretation engine operation can be presented as a physical quantity. In this aspect, based on the selected functional system of the engine, was assessed usefulness of the quantity for description reliability features of the system. To the analysis was applied Poisson's uniform process which made it possible to elaborate a model of run of worsening the considered system's operation taken as a random process of identical independent decreases of energy efficiency within a given time interval. The presented method is a valuable supplement for description reliability features of ship main engine what is important for realization of shipping tasks by sea. Additional advantage is versatility which makes that it can be applied to reliability analysis of any ship device or ship energy subsystem. Classification of the engine serviceability states with taking into account the assessment of its operation in energy-time aspect, schematic diagram of lubricating system of RTA48-TB engine and values of lubricating oil parameters in steady conditions for the engine load, graphical presentation of lubricating oil cooler operation graphical interpretation of the decreasing of oil cooler efficiency are presented in the paper
