Opis:: Accelerometric tests, similarly to laser tests (with regard to human health) are something of novelty. All standards related to this issue refer to sound intensity (measured using specialised microphones). The work presents results of accelerometric tests conducted during driving cycles on an inertial load chassis dynamometer Maha LPS3000. The object of the research was Mazda 3 1.6 (petrol), built in 2010, mileage 70 thousand km. The tests were related to vibration measurements on a chassis dynamometer using various, forced tractive effort (300, 500 and 700 N). No additional signal processing was used (except for operations necessary to create a spectrum) so as to present the whole vibration spectrum with special emphasis on the resonance frequency of human organs. The article presents vibration amplitude measured at the level of the headrest for three forced tractive efforts: 300, 500 and 700 N. The measurements were made at the speed of 60 km/h in the fourth gear (which corresponds to about 2000 rpm). The obtained results, indicate that the maximum value of harmonics fall in the range 85-95 Hz. Hence, they are resonance frequencies of eyeballs. In addition to this, one can state that the values of these harmonics are higher for higher values of forced tractive efforts. This would mean that seats should be additionally stabilised (dampened) to limit the influence of dangerous vibration on a human organism.

Opis:: Description of the test stand for investigation of the integrated powertrain (powerpack) for armoured modular vehicle (AMV), disassembled from vehicle, is presented in this paper. The powerpack unit consist of a diesel engine, a gearbox and a cooling unit with a hydraulic fan drive. The stand is equipped with measuring devices for torque measure, fuel consumption, exhaust smoke and exhaust gas components emission analysers. The powerpack has been loaded by a hydraulic dynamometer of power range up to 1250 kW. It is dynabar water dynamometer with high dynamics of load changes. For control the motor and drive, system the original control panels from the vehicle was used. The original start-up unit, mid fuel tank and air filters were used too. Research on the powerpack unit was made in the steady state versus the engine load and speed. The parameters of the engine and exhaust components were measured and compared with the catalogue values. Two modes of engine work were compared – economic and dynamic modes. Those differences between two modes are result of maximum fuel consumption decreasing. The parameters of engine work were comparable in middle and low range of engine load. On the stand investigation in transient states during free engine acceleration were made. It was found that additional load of engine is too high and this problem should be clarified.

Opis:: The study concentrated on slip phenomenon occurring at hydrokinetic converter in passenger car transmission system. Optimization of modern automatic transmission systems aims, on the one hand, to further increase the comfort of use, and on the other hand to improve the efficiency and reliability operation of individual components, in such a way as to ultimately result in lowering fuel consumption and also harmful emissions. One of the important factors affecting the mentioned transmissions properties as a whole system is the slip phenomenon occurring between the pump and the hydrokinetic converter turbine. The study presents the results of research on ZF 4HP20 and Fuji Hyper M6 gearboxes operating in vehicle transmission systems. The tests were carried out using the MAHA MSR 500 chassis dynamometer during driving at chosen test cycles. The research covered the transmission systems operating according to selected control algorithms affecting not only the gear shifting strategy but also the operation of the lock up clutch causing the transmissions slip values. As shown by the conducted research, the algorithm controlling the operation of the torque converter can have a significant influence on their operating indexes. The conducted analyses indicate the possibilities of improving the transmission operating indexes, especially in urban driving cycles.

Opis:: Possibility of improvement of work parameters of the turbocharged diesel engine through increasing of the liquid cooling temperature was the aim of presented investigations. Diesel engine was equipped in the closed vapour cooling system with metal separator made by using tubes and copper pipe fitting. The water was used as a cooing liquid. Investigations were realised at pressure in cooling system less then 0,1 mpa what limited the range of torque and the engine speed considerably. It was got increasing the temperature of cooling liquid flown out from the engine to approx. 110 centigrade. The growth of the liquid temperature caused decreasing of the carbon oxide parts (to 50%) and hydrocarbons (to 50%) in the range of the low engine torque. However the parts of the oxides of nitrogen grew up near this (approx. 50ppm) and the temperature of exhaust gas was higher also (about 50 centigrade). The temperature of lubrication oil was higher 40...60°C also. The fuel consumption of the engine was comparable. Increasing of the flow intensity of the cooling liquid through additional cooling of the compensation tank and the using the bigger water pump is purposeful during future investigations. It is necessary to use control system for regulation of cooling intensity.
Celem prezentowanych badań było sprawdzenie możliwości poprawienia parametrów pracy turbodoładowanego silnika o zapłonie samoczynnym poprzez zwiększenie temperatury cieczy chłodzącej. Silnik ten wyposażono w zamknięty układ chłodzenia z metalowym separatorem wykonanym z rurek i kształtek miedzianych. Cieczą chłodzącą była woda. Badania przeprowadzono przy nadciśnieniu nieprzekraczającym 0,lmpa, co znacznie ograniczyło zakres obciążenia i prędkości obrotowej silnika. Uzyskano zwiększenie temperatury cieczy chłodzącej na wypłynie z silnika do ok. 110oc. Wzrost temperatury cieczy chłodzącej spowodował zmniejszenie udziałów tlenku węgla (do 50%) i węglowodorów (do 50%) w zakresie małego obciążenia silnika, jednak wzrosły przy tym udziały tlenków azotu (ok. 50ppm) oraz wyższa była temperatura spalin (ok.50 stopni Celsjusza). Wyższa była także temperatura oleju smarującego silnik o około 40...60 stopni Celsjusza. Ekonomiczność pracy silnika była porównywalna. Podczas dalszych badań celowe jest zwiększenie intensywności przepływu cieczy chłodzącej poprzez dodatkowe chłodzenie zbiornika wyrównawczego i zastosowanie większej pompy wodnej. Celowe jest zastosowanie systemu automatycznego sterowania intensywnością chłodzenia.
