Increasing greenhouse gases impose severe concern over the environment resulting in rising dangerous calamities of climate change in the form of floods, etc. Major disadvantages like intermittency of electric vehicles need to be charged after traveling fixed distance. The paper develops an algorithm for a selected industrial electric vehicle to be controlled at different speeds that envisages working on real time Internet of Things (IoT) based Global Po-sitioning System (GPS) signals. It engages the ARM core based STM micro-controller in conjunction with mesh networked Bluetooth Low Energy (BLE) to govern the operations besides enabling it to be dynamically monitored. The system design considers the vehicle parameters that include the speed of vehicle and the engine, State of Charge (SoC) and State of Health (SoH) of battery together with real time GPS based navigation system using IoT bundled GPS based maps interface. The methodology involves a closed loop monitoring with specified sequence of steps that augur the system to operate at defined speed over designated work shifts and schedules. The procedure introduces an embedded C environment with a process of unit-testing based simulation to capture the merits of schema in terms of an improved vehicle performance under varying parametric conditions.

Artykuł przedstawia opis prac koncepcyjnych, projektowych oraz nad opracowaniem parametrów wytwarzania koła do pojazdu wysokiej mobilności, wykonanego w technologii druku 3D. Opracowane koło było z przeznaczeniem do niekonwencjonalnego pojazdu off-road, nazywanego łazikiem marsjańskim. Pojazd taki jest od wielu już lat opracowywany przez studenckie Koło Naukowe Pojazdów Niekonwencjonalnych Off-Road i z sukcesami bierze udział w zawodach międzynarodowych. Kolejna wersja pojazdu zakładała zwiększenie udziału nowych technologii wytwarzania podzespołów pojazdu, co powinno pozwolić na lepsze dopasowanie parametrów użytkowych pojazdu do rzeczywistych warunków panujących podczas zawodów. Punktem odniesienia były parametry koła dotychczas wykorzystywanego w pojeździe i wykonanego z Cordury.

The article presents conceptual work, design work, and the development of parameters for the production of wheels for a high-mobility vehicle made in 3D printing technology. The developed wheel was intended for an unconventional off-road vehicle, called the Mars rover. For many years, such vehicle was being developed by the student Scientific Association of Unconventional Off-Road Vehicles and it has participated successfully in international competitions. The next version of the vehicle assumed the use of a technology of manufacturing vehicle components which ensures adjustment of the vehicle‘s operational parameters to the conditions prevailing during the competition. The benchmark was the parameters of the wheels used in the vehicle and made of Cordura.

Celem niniejszego artykułu jest przedstawienie podstawowych wymagań, jakie powinny spełniać koła jezdne do pojazdów wysokiej mobilności. Zakres wymagań i analiz został ograniczony do łazików kontakcie koła z podłożem, w tym łazika Scorpio X, tworzonego przez Koło Naukowe OFF-ROAD działające na Wydziale Mechanicznym PWr. Autorzy scharakteryzowali aktualne rozwiązania stosowane w pojazdach najlepszych, wybranych kół studenckich z całego świata. Punktem wyjścia była analiza sił działających na koła jezdne analizowanego pojazdu w wybranych warunkach ruchu. Oceniono również istniejące rozwiązanie wykonania kół materiałowych wykonanych z materiału Cordura.

The target of this article is to define requirements which should be satisfied by wheels of high mobility vehicle. Divagations are made based of mars rovers, including Scorpio X rover made by OFF-ROAD Student Association based at Mechanical Faculty at Wroclaw University of Science and Technology. Authors introduced several solutions applied by the most successful teams from all around the world. The starting point was the analysis of the forces acting on the road wheels of the analysed vehicle in selected traffic conditions. The existing solution for fabric wheels made of Cordura was also assessed.

The operation of diesel engine is closely connected with controlling the process of injecting the fuel into the cylinder. It influences proper combustion process, which translates directly into irregular engine operation resulting in dumping and noise. It is related to improper control of fuel injection which is connected with improper completion of expected control strategy that can be a result of defective injection system. Irregular engine operation can also be caused by total lack of initiated combustion process in specific cylinder of the engine or in several cylinders, described as misfire, or ca be a result of differences in combustion process in individual operation cycles / engine cylinders. The effect is an engine working irregularly (there is instability of rotational speed) and emitting increased amount of pollutants. As a consequence the secondary fuel purification systems located in the exhaust system can be damaged. Therefore, it is required to choose the fuel injection control parameters in a way that enables detecting and correcting the process of fuel injection in order to minimize effects resulting from improper process of fuel combustion in individual cylinders or even lack thereof. It is useful to suggest diagnostic parameter that can be used to detect engine faultiness or elements of the accessories such as e.g. injection system. Ability to apply such control and correction of injection dose is provided by modified mechatronic in-line injection pump. The study shows results of researches on modified injection system with mechatronic in-line injection pump that enables identification of misfire and preventing irregular operation of diesel engine.

Current engine technology for on-road vehicles allows us to meet the existing and planned future standards for emission. Because combustion engines, especially self-igniting are being used for very different purposes like: road transport, rail-way transport, shipping, industry, military and agriculture, these engines work in different and often difficult conditions. A very significant group of vehicles used for the most difficult of the a forementioned areas ofuse are "Off-Road" vehicles. For those vehicles we also use rigorous regulations to govern dangerous chemical emissions such as Tier, Bin and Californian LEV. In those types of vehicles the fuel powered systems very often use mechanically controlled diesel injection pump. These pumps are characterized by high tolerance to the quality and type ofpetrol as well as reliability, which is very important especially in "off-road" vehicles. At work a conception was described of system of powering the engine diesel which will let for reaching of future emission exhaust quality standards. In the paper only initial outline of the idea of the injection 's system for „off-road" vehicles, is introduced. This system needs follow-on in the field both interactions with the EGR valve, with the injection 's system as well as in the matter of interaction with ECU of the injection 's system.
