Opis:
Transport drogowy oraz morski oparty jest głównie na wykorzystaniu paliw ropopochodnych, tj. ropie naftowej, benzynie oraz LPG (Liquefied Petroleum Gas). Światowe zasoby ropy naftowej stale się kurczą i przewiduje się, ze wystarczą na kilkadziesiąt lat. Ponadto stale zwiększające się obostrzenia dotyczące emisji spalin powodują, że silniki są coraz bardziej skomplikowane, co przekłada się na wyższy koszt oraz niższą niezawodność. Dlatego też zauważalny jest trend w celu poszukiwania alternatywnych paliw do zasilania pojazdów. Obecnie można wyróżnić trzy kierunki rozwoju technologii: zasilanie energią elektryczną, wodorem lub gazem ziemnym. Ze względu na fakt niskiej pojemności baterii, co przekłada się na niski zasięg pojazdów i poważne trudności z magazynowaniem wodoru oraz niską efektywność termodynamiczną ogniw, najbardziej perspektywicznym kierunkiem wydaje się zasilanie pojazdów gazem ziemnym. Zasoby gazu ziemnego są znacznie większe w porównaniu do ropy naftowej. Ponadto spalanie gazu ziemnego praktycznie eliminuje emisję szkodliwych dla zdrowia tlenków azotu, siarki oraz cząstek stałych. Jest on również paliwem powszechnie dostępnym, ze względu na znaczne pokrycie terytorium Polski rurociągami. Jednakże ze względu na niską gęstość energii gazu ziemnego w warunkach otoczenia, wymaga on specjalnego przechowywania – może być magazynowany jako gaz sprężony do ciśnienia ponad 200 barów (CNG – Compressed Natural Gas) lub w postaci skroplonej (LNG – Liquefied Natural Gas). Pozwala to na zwiększenie gęstości energii do poziomów porównywalnych od oleju napędowego i benzyny. Dodatkowym zagadnieniem jest możliwość wykorzystania chłodu pochodzącego z odparowania LNG do celów klimatyzacyjnych lub chłodniczych. Jest to jednak uzasadnione w przypadku transportu ciężkiego, gdzie strumień gazu jest relatywnie wysoki.
The road and maritime transport is mainly based on the petroleum fuels as diesel, gasoline and LPG (Liquefied Petroleum Gas). Due to their harmful effect on health and the shrinking resources, new fuels are sought. At present we can observe three main directions: vehicles powered by electricity, hydrogen and natural gas. In the case of electricity, problems are still present with the capacity of the batteries and, hence, the low range of the vehicles. The use of the hydrogen is difficult due to storage problems and the low thermodynamic efficiency of the fuel cells. That is why natural gas can be the best alternative fuel and be a good way to reduce pollution such as: nitrogen oxides, sulfur oxides and solid particles. Moreover, natural gas is easily available by the gas pipelines. However, natural gas under ambient conditions is characterized by low energy density. That is the reason why it must be stored as gas pressurized over 200 bar (CNG – Compressed Natural Gas) or as the liquid gas (LNG – Liquefied Natural Gas). This kind of storage allows the energy density to be increased to the level comparable with diesel or petroleum. An additional aspect may be cold energy recovery from the evaporating LNG. The cool can be used in air conditioning or in refrigeration. That solution is especially interesting in heavy transport, where the streams of liquid gas are relatively high.

Opis:
A theory of cumulated fuel consumption in process ofvehicle operation is described. The method of creation the mathematical model and procedure of determination of model variables is shown. The mainfeatures of cumulated fuel consumption are painted attention. li is shown that the theory of cumulated fuel consumption can be use to description of the fuel consumption from beginning the exploitation of vehicles and also for the situation when the vehicle are in exploitation from any time and further fuel consumption are unknown. An example of utilisation of elaborated theory for assessment of operation of passenger car is also presented. It has been shown that applying the theory of cumulated fuel consumption, the course of such consumption can be accurately described also in this case. This proposal can be formulated in spite of making some simplifications. This is because the unknown value of the accumulated fuel before start the time of observation operation will be determined using the average (from the average) fuel consumption. This simplification greatly facilitates the flow of the calculations and it seems does not offend errors in the calculations. Method of determining the average is discussed in the article. It appears that such treatment may be justified by the fact that the mistake is, in principle, systematic error. Very high coefficients of mathematical model to fit the measured data are very interesting. Such regularity was observed during researches in buses transport [l], intercity buses, and the fleets of various vehicles (the results of researches are not yet published).The introduction of the theory of cumulated fuel consumption as one of the important parameters to assess the operation of the vehicle or vehicles may also be useful in exploitation researches. At present times the researches in which the vehicles are already in service and the engine control mops are tuned (chip tuning), are made. A good performance of these changes is often observed on chassis dyno but that is not properly sanctioned in natural exploitation. Experimentation with such issue is underway and will be the subject of future analysis (and publications).

Opis:
The article presents the laboratory tests results of the influence of the diesel oil content in a mixture with rapeseed oil on the operating parameters of a diesel engine with the CommonRail fuel supply system. Fuel mixtures with a rapeseed content of 0%, 50%, 70%, 100% were used. The article presents the results of tests carried out for various configurations of the object. The measurements included tests of exhaust gases: the content of carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides as well as specific fuel consumption and exhaust gas temperature. As a result of the research, it was noticed that the use of rapeseed oil causes a significant increase in fuel consumption and an increase in emissions. At a crankshaft speed of 2500 rpm and a torque generated by the engine crankshaft of 12 Nm, the specific fuel consumption for a 0% rapeseed content is 310 g/kWh. For the same engine operating conditions and the same rapeseed content of the fuel, the fuel consumption for 100% rapeseed content is 330 g/kWh. For the same engine operating parameters, analysis of the carbon dioxide content in the exhaust gas yields a value of 7.8x104 ppm for a rapeseed content of 0%. For the same engine operating conditions and for the oilseed rape content in the fuel is 100% 8.4x104 ppm. The mathematical models describing the effects of engine operating parameters and rapeseed oil content in the mixture on the observed values were created with the Scilab program. The degree of agreement of the determined mathematical models was checked by calculating the coefficient of determination (R2). The results are shown in 3D figures.

Opis:
Vehicles with electric propulsion systems are increasingly more often equipped with solutions that improve their drive system’s efficiency. The latest vehicle model with a fuel cell hybrid system – Toyota Mirai was used in this experiment. The design of this vehicle is similar to that of hybrid vehicles in many aspects. However, new fuel cell technologies are being developed for automotive use, including compressed hydrogen tanks and control systems. The article presents an analysis of a fuel cell operation during vehicle start-up and driving, with particular emphasis on the hydrogen injection strategy of the three fuel injectors used in the fuel cell. The fuel cell interaction with the high-voltage battery has also been characterized. It has been shown that increase in the electrical supply voltage of the vehicle’s electric motor can be observed at high torque values of the electric motor. The maximum voltage gain – approximately three times (up to about 650 V) – allows for double the torque of the drive system compared to the standard value.

Opis:
Among the possible electric powerplants currently driving low-payload UAVs (up to around 10 kg of payload), batteries offer certain clear benefits, but for medium-payload operation such as aerotaxis and heavy-cargo transportation UAVs, battery capacity requirements restrict their usage due to high weight and volume. In light of this situation, fuel cell (FC) systems (FCS) offer clear benefits over batteries for the medium-payload UAV segment (> 50 kg). Nevertheless, studies regarding the application of FCS powerplants to this UAV segment are limited and the in-flight performance has not been clearly analysed. In order to address this knowledge gap, a feasibility analysis of these particular applications powered by FCS is performed in this study. A validated FC stack model (40 kW of maximum power) was integrated into a balance of plant to conform an FCS. As a novelty, the management of the FCS was optimized to maximize the FCS efficiency at different altitudes up to 12500 ft, so that the operation always implies the lowest H2 consumption regardless of the altitude. In parallel, an UAV numerical model was developed based on the ATLANTE vehicle and characterized by calculating the aerodynamic coefficients through CFD simulations. Then, both models were integrated into a 0D-1D modelling platform together with an energy management strategy optimizer algorithm and a suitable propeller model. With the preliminary results obtained from the FCS and UAV models, it was possible to ascertain the range and endurance of the vehicle. As a result, it was concluded that the combination of both technologies could offer a range over 600 km and an endurance over 5 h. Finally, with the integrated UAV-FCS model, a flight profile describing a medium altitude, medium endurance mission was designed and used to analyse the viability of FC-powered UAV. The results showed how UAVs powered by FCS are viable for the considered aircraft segment, providing competitive values of specific range and endurance.

Opis:
Contemporary and future battlefield may be characterized by a great dynamism of action in both defensive and offensive operations. It is possible, that armoured and mechanized troops, acting at first attack, will suffer from shortages of supplies of materials and other equipment, especially propellants. It concerns particularly a fuel to engines of driving vehicles. Therefore in many cases for engine powering (as multi-propellant engines or adapted to work on substitute fuels) may be used substitute fuel. The fuel parameters sometimes may be much different from parameters of diesel. So it is substantially important to estimate their dynamics during the planning stage of combat missions. Paper includes attempt to estimate dynamic features of the combat vehicles using substitute propellants. Applying substitute propellants leads to reducing the power of the engine up to 10 % comparing to diesel. It has essential impact on lowering the dynamic ratio at similar level. That leads to lower maximum drive speed at given resistance ofmotion and reducing the ability to climb slopes. There also appears deterioration of spurt, extending the time of reaching speeds at about 17%. Paper shows results of traction calculations of combat vehicles and the influence of powering them with renewable fuel on their effectiveness.

The article discusses the development of the world EV fleet in years 2010-2017. Estimates of fleet of plug-in hybrid electric vehicles (PHEV) and BEV in the world are presented. The total number of PHEVs registered in the world in 2016 was roughly 800 thousand (650 thousand in EU). Despite the fact that the sale of electric vehicles has increased considerably in recent years, in particular over 1.1 million in 2017, and also hybrid electric vehicles (PHEV) to approx. 760 thousand in 2017. The article also discusses the development of the electric vehicles market and annual new registrations of vehicles in a breakdown into respective countries. China is the definite leader in this area. In 2017 there were almost twice more BEVs registered in China than in the US and EU together. While the increase in the sale of BEVs in years 2016-2017 in the EU and the US accounted for approx. 50%, it came to over 90% in China. Among eight top worldwide BEV producers, there are four Chinese manufacturers. In the analysed 2017, there were slightly more than 7 thousand of hydrogen-fuelled passenger cars (FCEV) in use, with over 3,500 in the US, 2,300 in Japan and approx. 1,200 in Europe, and several hundred hydrogen-fuelled buses and several dozen hydrogen-fuelled trucks. The article also addresses the development of hydrogen refuelling stations (HRS) in recent years in different countries in the world, bearing in mind that the quantitative development of the hydrogen-fuelled car fleet is strongly associated with the number of hydrogen refuelling stations.

Opis:
In the recent times, lot of research work carried out in the field of fuel cells explicitly divulges that it has the potential to be an ultimate power source in upcoming years. The fuel cell has more storing capacity, which enables to use in heavy power applications. In these applications, power conditioning is more vital to regulate the output voltage. Hence, we need a dc-dc converter to provide a constant regulated output voltage for such high-power system. Currently, many new converters were designed and implemented as per the requirement. This paper has made comparative study on several topologies of the quadratic high gain dc-dc converter and the applications where these topologies can be used when the fuel cell is given as a source. Also, we have compared various parameters of all the converters considered and generated the results with steady-state and dynamic study. In this article, we briefed the types of analysis carried on the dc-dc converter to study its performance. Moreover, various application of fuel cell is presented and discussed. This paper will be a handbook to the researchers who start to work on high gain dc-dc converter topologies with quadratic boost converter as a base. This article will also guide the engineers to concentrate on the fuel cell components where it needs to be explored for optimizing its operation.

The paper presents optimization of the drive system in terms of adapting it to the characteristics of another engine. Powertrain parameters in a vehicle with an internal combustion engine were selected based on the following criteria: fuel consumption, engine dynamics, and emission standards for harmful substances. A light-duty passenger vehicle with gross vehicle weight rating (GVWR) of 3.5 tons was modified by replacing a spark-ignition engine with a diesel engine. The gear ratio in the powertrain had to be modified accordingly to optimize the engine’s performance, enhance engine dynamics, minimize fuel consumption and toxic emissions. The optimization of selected parameters of the vehicle driveline was performed based on the requirements of the standard NEDC and WLTC cycles.

Opis:
Fuel consumption measurement itself is a demanding process and it is difficult to determine the exact consumption of a vehicle. Fuel consumption can be determined in various ways. One way to determine consumption is through driving tests. We know several types of driving tests. Nowadays, most vehicles and all new vehicles can provide a wealth of data to the driver directly during vehicle operation. One of them is the data on the consumption of the vehicle also through the on-board computer located in the vehicle. The information provided to the driver may not reflect reality. In most cases, they are inaccurate and do not correspond to reality. Therefore, the subject of the research will be to verify the accuracy of the provided data on vehicle consumption by the on-board computer. The aim of the research will be to determine the extent to which consumption data are true. Vehicle consumption, as well as measurements are performed on one vehicle in every day traffic. This will ensure that it is possible to compare the measured data with each other.

Opis:
This paper deals with some computational study of multi-criteria optimization in fuel distribution problem. We consider vehicle routing problem, e.g. routing of a fleet of tank trucks, for one of the famous polish petroleum companies. For the purpose of solving this problem, we developed the random search algorithm, which explores the broad range of feasible sets of routes and searches for non-dominated multi-criteria solutions. The problem is examined on real data, which contains distances between 50 petrol stations and one central warehouse (refinery). Obtained results indicate, that it is possible to obtain single solution and satisfy both optimization criteria. Based on the analysis of the collected data, we formulate a number of proposals useful in future for construction of algorithms for multi-criteria fuel distribution optimization.
