Opis:
The article presents construction concept of a tractor with hybrid, diesel-hydraulic and diesel-electric drive meant for the use in livestock holdings. The tractor is enabled to cover short distances with the combustion engine switched off. This solution uses independent engines to propel front and rear axles. This article presents a computer model and simulation results for the project of a hybrid, diesel-electric tractor based on a benchmark machine Fendt 516. Aside from the ability to drive with diesel engine switched off, the proposed solution has additional positive features allowing smooth transition of relation of peripheral speed of the front and rear wheels. It enables to obtain higher tractive powers for various conditions in a broader range than for a traditional solution (with propelling both axles with one engine through different transmission systems and specific difference of peripheral speed of the wheels). The computer model was built on the basis of the benchmark machine.

Opis:
The structures of modern traction vehicles are based on new generation devices. Technical progress within the field of power transmission concerns such elements as sources of power supply, electric devices and energy electronic solutions in power transmission systems. The prototypes of traction vehicles being currently drawn up are hybrid vehicles using different kinds of sources of power supply ofpower transmission systems, the most important of which are combustion engines, contact systems, supercapacitors (ultracapacitors), accumulators and fuel cells. Main engines are usually electric machines. In energy electronic starting systems it is permissible to use all kinds of main electric engines, for example, direct-current motors (inline engines, commutator motors with permanent magnets or non-commutator motors) or three-phase motors of alternating current (induction and synchronous). This means a complete change of rules in energy managing in a vehicle. Sources of energy can have the function of basic power supply (contact system, combustion engine or combustion cell) or the function of power supply support (supercapacitors, accumulators or fuel cell). New functions of drive operation will be available, namely, leveling of basic power supply load, recuperation of braking energy of the whole train set, driving at the temporary disconnection of basic power supply (short-term application of accumulator as basic power supply). Each of the above functions can contribute to the improvement of watt-hour efficiency of the system or to prolonging the range of driving. Therefore, it is necessary to undertake research on new generation power transmission systems. Research tasks focus on measurement of state variables of a drive, analyses of traction signals, modeling of drive operation in the conditions of driving cycle realization, verification of a model, drawing up a strategy of energy management in order to achieve the best watt-hour efficiency and the range of driving. In the article presented, sample results of researches on applications of hybrid power transmission systems conducted in various national research centers will be demonstrated. They concern both theoretical research (model simulation) and prototype research. The conception will be presented of a laboratory station for conducting research on modern sources of power supply and drives, which is currently being built at the Faculty of Transport of Warsaw Polytechnic at the Division of Exploitation of Tracking Systems and Electric Equipment in Transport.

Opis:
Continuous increased interest in hybrid drive systems enabling the reduction of fuel consumption and emissions of harmful substances into the atmosphere, as well as their use partly as zero-emission drive in vehicles provides the basis for the development of these types of drive systems. Such trend is indicated by sales analysis of hybrid drives, and this means that actions taken towards of reduction of fuel consumption are still justified. The article reviews combustion engines for hybrid drive systems as far as determination of their operating conditions, indicating mean effective pressure and power/displacement ratio are considered. The concept of hybridization was defined as a measure of the degree of utilization of vehicle electric drive systems (or its drive support). The analysis was conducted on the basis of vehicles equipped with different hybrid drive systems with combustion engines with spark ignition and compression ignition. The hybridization indexes for different groups of hybrid drive systems were determined and significant discrepancies in the way of their determination were pointed out.
Ciągły wzrost zainteresowania napędami hybrydowymi pozwalającymi na ograniczenie zużycia paliwa, zmniejszenie emisji składników szkodliwych do atmosfery, a także częściowe ich wykorzystanie jako pojazdów zeroemisyjnych powoduje rozwój tych jednostek. Wskazują na to analizy sprzedaży napędów hybrydowych, a to oznacza aktualność działań podejmowanych w kierunku ograniczenia zużycia paliwa. W artykule dokonano przeglądu silników spalinowych napędów hybrydowych w aspekcie określenia ich warunków pracy oraz wskaźników wysilenia. Określono pojęcie hybrydyzacji jako miary stopnia wykorzystania układów elektrycznych napędu pojazdu (lub jego wspomagania). Analizy dokonano w odniesieniu do pojazdów wyposażonych w różne systemy napędu hybrydowego z silnikami spalinowymi o zapłonie iskrowym i samoczynnym. Określono wskaźniki hybrydyzacji różnych grup napędów hybrydowych oraz wskazano na znaczne rozbieżności w sposobie ich określania.

Opis:
The life cycle cost (LCC) methodology provides understanding of economic aspects of urban buses equipped with different types of propulsion. The LCC analysis delivers the sum of costs related to the acquisition, operation, repair and maintenance disposal as well as the costs for the each bus power train technology. The method allows to take into account all costs for the whole vehicle’s life cycle and creates a precondition for precise information database for decision making. In addition to the economic factors LCC can be extended to environmental aspects such as greenhouse gases emissions. The environmental impacts of the vehicle lifetime may be presented in monetary values. The paper presents the Life Cycle Cost analysis undertaken for urban buses fitted with conventional, series hybrid and parallel hybrid drives. Provided LCC analysis includes the economic and environmental aspects. The paper also delivers the evaluation of the total air pollutant emissions for all stages of lifetime of the each analysed urban bus. The results show that the hybrids have slightly lower life cycle cost than conventional bus. Moreover, hybrid buses were found to have lower life cycle environmental impacts.

Possibilities of combustion engine – electric machine assembly run irregularity improvement have been presented in the following paper. Such system is the basic one in numerous hybrid car available on the market but the concept of using an electrical machine for reduction of rotational speed changeability amplitude in reciprocating machines could be utilized in any drive unit, especially in ship propulsion. This idea consists in generation of braking torque by the electric machine whenever the coupling shaft increases its rotational speed and vice versa, driving the system when the momentary speed is lower than the average speed within a complete shaft rotation.

Opis:
The drive to reduce fuel consumption of vehicles equipped with internal combustion engines leads to an increasing share of hybrid drives used in various means of transport. Such hybrid vehicles, thanks to the use of diesel-electric drive systems, allow for a fuel consumption reduction, and thus to reduce the carbon dioxide emissions. This fuel consumption reduction results from a specifically selected energy flow strategy in hybrid systems. This strategy was the focus of the research performed in order to identify the energy flow conditions in a hybrid drive system in driving conditions corresponding to the RDE test. A Lexus LS 500h vehicle was tested in two drive modes, while determining the related energy flow conditions, including the operating conditions of: electric motors, internal combustion engine and battery. Energy balance was determined taking into account the high voltage battery discharge and charging energy as well as the energy recovered during regenerative braking. It was found that in the RDE test conditions the vehicle is in electric mode for over 30% of the distance and 35% of the drive time, with the energy balance of the vehicle being positive (SOCend > SOCstart). Additionally, it was pointed out that the time spent in the electric mode when driving in urban conditions is about 50% and decreases to about 15% for highway conditions.

Opis:
The powertrain of an urban vehicle was subjected to detailed simulations. This study was conducted with the aim of getting to know the operating principle, verification of assumptions adopted during its design and determination of most effective control procedures to be applied with regard to its powertrain. However, the most important aspect involved the aspect of the power distribution between the engines, electrical machine and vehicle wheels in the particular operating modes of the powertrain. A study was conducted in the MATLAB/Simulink environment with the purpose of finding a configuration of an electrical machine coupling with a combustion engine that offers the greatest advantages in terms of the range of the speed ratio, demanded performance of the electrical machine and maximum power output. The simulations indicated that control of the speed ratio of the vehicle could be gained by application of an electrically controlled planetary gear. The range of the transmission ratio is relative to the ratio of the planetary gear, speed range of the combustion engine as well as electrical machine. The efficiency of the battery charging in the hybrid mode is mostly relative to the operating point of the engine. The optimization of the process of power generation by the electrical machine requires that the operating point of the engine be maintained at a range at which its high performance is guaranteed.

Electric or hybrid vehicles are becoming increasingly common on roads. While electric vehicles are still more or less intended for city traffic, hybrid vehicles allow normal use due to wider driving range. The use of internal combustion engines in hybrid drives is still an inspiration to find the way to reduce the production of emissions. Numbers of alternative energy resources were studied as a substitution of conventional fuels for hybrid vehicles drives worldwide. The paper deals with the possibility of using alternative fuels as CNG, LPG and LNG in combination with hybrid drive of a midibus with the capacity of 20 passengers. Various aspects and techniques of hybrid vehicles from energy management system, propulsion system and using of various alternative fuels are explored in this paper. Other related fields of hybrid vehicles such as changes of vehicle weight or influence of electric energy sources on the total vehicle emission production are also included.

Opis:
One of the alternative powertrain systems of cars, commercial vehicles and mobile machines are hybrid drives with pneumatic motors for compressed air. This paper presents a mathematical model and the results of simulation calculations of piston pneumatic motor. Mathematical model was based on the fundamental principles of mechanics, thermodynamics and rights of airflow. For simulation model parameterization, prototype of such engine was built and installed on dedicated test stand. Performed experimental research allowed achieving values of coefficients and components characteristics used for model estimation. One of the important tasks of this study was to create the control system of the compressed-air supplied engine. For this purpose an appropriate pneumatic and electronic component were selected and also an algorithm was created which would facilitate changing of the engine settings in order to obtain the best performance. Using elaborated simulation model, series of calculation were performed for different parameters of pneumatic motor, like cylinders diameter and stroke, length of the crank, compressed air pressure and valves size. A lot of attention was devoted to determine the influence of control system settings, such as valves opening and closing in reaction to crankshaft position, on motor properties. When discussing the results of calculations considerable attention was paid to the power, torque and efficiency values. To illustrate performance of designed engine, simplified model of light vehicle was used to calculate possible to achieve acceleration, velocity and travel distance.
