Opis:: 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.

Opis:: Travelling off the road requires an adequate vehicle. The basic car needs to be properly chosen and prepared according to its destination. Due to understanding problem, the paper explains differences between various kinds of four-wheeling like extreme passage rally, time race or just off-road expeditions. The paper contains classification and description of the most popular in western Europe terrain cars, their construction solutions and general advantages and disadvantages. In the document are also presented vehicle selection criteria. This issue is as significant as proper choice of adequate driving type. Established criteria relate to variety and power of engines, four wheel drive, reduction gearbox, differential locks, weight, and the most important geometric and operation parameters. Due to above features is made the comparison and choice of car for further development. The review, evaluation and selection of building elements are customized to chosen car. Project of development of interior contains construction assumptions, strength calculations and numerical model of the drawer located in the rear of the luggage. Additionally there are also drawings of arrangement of particular body elements. Graphical model, drawings and strengths calculations are performed using the Autodesk Inventor Professional 2011 and AutoCAD Mechanical 2011. Just as the chosen equipment, project is adjusted to dimensions of luggage area of chosen car. Author’s design includes original spacing between the openings in exterior, what allows embedding drawer without any interference in the car body.

Tytuł:: Analysis of the influence of the speed of impact against an obstacle on the dynamic loads acting on occupants of an automotive vehicle with body-on-frame design of the load-bearing structure

Opis:: The dynamic loads acting on a human body during a road accident may cause bodily injuries. The values of such loads measured on test dummies make it possible to predict the effects of the loads on vehicle occupants, with the prediction being based on biomechanical modelling. The dynamic loads were analysed with making use of experimental results of tests where an automotive vehicle came into a head-on collision with an obstacle. In the test vehicle, a Hybrid III test dummy provided with a set of sensors was held with seat belts in the driver's position. By using the experimental results and the determined extreme values of dynamic loads, the dependence of the dynamic loads on the speed of vehicle impact against an obstacle is searched. The knowledge of this dependence will facilitate the prediction of values of dynamic loads and the resulting dangers to the human body that would arise from road accidents. The tests were carried out on an off-road passenger car, where a frame makes a basis of the entire loadbearing structure, i.e. connects all the vehicle components and systems into a self-contained whole and supports the vehicle body. Vehicles with load-bearing structures of this type predominate among those used for military applications. Results of crash tests of such vehicles are rarely published.
Obciążenia dynamiczne, działające na ciało człowieka podczas wypadku drogowego, są źródłem obrażeń. Pomierzone na manekinach wartości tych obciążeń pozwalają, na podstawie modelowania biomechanicznego, na prognozowanie ich skutków dla osób jadących. Analiza obciążeń dynamicznych została przeprowadzona z wykorzystaniem rezultatów badań eksperymentalnych, w których samochód uderza czołowo w przeszkodę. W samochodzie tym manekin Hybrid III z zestawem czujników, przypięty pasami bezpieczeństwa, zajmował pozycję kierowcy. Wykorzystując wyniki badań eksperymentalnych i wyznaczone wartości ekstremalne obciążeń dynamicznych, poszukuje się ich zależności od prędkości uderzenia samochodu w przeszkodę. Poznanie takiej zależności ułatwia prognozowanie wartości obciążeń dynamicznych i powstających zagrożeń dla ciała człowieka w wypadkach drogowych. Badaniom poddano samochód osobowo-terenowy, w którym rama stanowi podstawę układu nośnego, czyli łączy wszystkie zespoły i układy w jedną całość oraz podtrzymuje nadwozie. Samochody o takiej konstrukcji nośnej dominują w zastosowaniach wojskowych. Wyniki ich badań zderzeniowych są rzadko publikowane.

Opis:: 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.
