Opis:: Analyse of possibility of the SB3.1 investigative diesel engine modernisation is showed in this paper. The engine is the excellent tool permitting to conduct investigative work over processes of fuel mixture production, spontaneous ignition and burning in a diesel engine with direct injection. It makes possible put in the changes of compression rate, the camshaft timing angle and the fuel injection timing angle. The obsolete system of the engine feeding, equipped with row injection's pump and injector come from the SW-680 engine is his drawback. Use of injection system type Common Rail allows solution of imperfection of this engine. That system would permit to extension of the engine SB3.1 investigative possibilities on investigation of processes limiting the emission of toxic compounds in exhaust gases and especially the soot filters and the catalytic afterburners or systems of reducing of nitrogen oxides emission. The modernization of engine SB3.1 contains the change of a high pressure pump with fuel pressure over 135 mpa and electronically controlled injector. The engine has also to be equipped in number of the control and measuring devices and the control unit to control of influence of converting gathered measuring signals on a fuel dose injected to cylinder.

Opis:: Investigation scheme of the unmanned vehicle is shown in the paper. It is the unmanned vehicle planned to use in military application. Using the unmanned vehicles on modern war field is increasingly popular. The unmanned vehicle is powered with a hybrid propulsion system. The main source of energy is diesel engine and electric generator. It supplies the battery and six propulsion electric motors. In the propulsion system is a lot of components: controllers and electric devices. Is important to know how it works in load condition. Investigation stand was constructed to break all drive wheels. There will be done measuring of electric parameters of the hybrid propulsion system. Temperature of the battery and electric motors, fuel consumption of internal combustion engine needed to appreciate of load and energy balance will be measured as well. Investigation equipment which will be used during investigation is also performed in the paper.

Opis:: Solution of the propulsion system of the unmanned vehicle elaborated and built in the Laboratory of Internal Combustion Engines Military University of Technology is shown in the paper. Unmanned vehicles are about to play key role in modern warfare. There are many types of unmanned vehicles. Those which can operate in urban areas, especially inside buildings are considered as a most useful for modern army. Most unmanned vehicles are battery operated, causing low range or low speed of the vehicle. Internal combustion engines are not proper for operation inside buildings, due to exhaust gases produced by engine. Connecting two types of propulsion system, defect of range in battery and gases in combustion engines are eliminated, because we can program vehicle to not turning on engine inside buildings. Using a module for those types of vehicles, we can design entire gamut of unmanned and even manned vehicles, decreasing design costs and repair time due to parts repeatability. Using a prepared propulsion module, design engineer can freely determine length, width and wheel track of designed vehicle. Designed modules enable vehicle fast return to combat ability, due to parts repeatability. One module, used as a host, can reconstruct damage vehicle. There is possibility of using different engines, enlarging list of available modules. Economic factor has also big meaning, due to parts repeatability.

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 paper describes standard methods of diagnosing of the AMV (the Rosomak) drive unit technical condition used in daily operation in military missions in Afghanistan. Main rule of the method of diagnosing of the vehicle technical condition is using an external diagnosing system. This system is connected to the vehicle at the time of checking of operation of the powertrain control system configuration of the drive unit to permit the diagnosis, including examination of the engine and gearbox. Enhanced diagnostic system is connected to the OBD system with using standard PC computer with appropriate software. Stored examples of the results of the operation of such system are included in the paper. Measuring was led on a dynamometer stand to perform research of a propulsion unit in work condition. Measurements of the engine parameters were led in steady state and transient engine operating conditions. Unsteady-state condition studies were carried out using the method of free-range acceleration of the engine. Pointed out the merits of the development of this type of study due to the perceived potential and usefulness of the results obtained. The results of studies carried out by various methods and assess the current condition of the engine and the entire powertrain were compared.

Opis:: Article presents the energetic balance of small-unmanned vehicle hybrid power transmission. The vehicle equipped with series hybrid transmission consisted of electric engines connected to the battery pack and small Diesel power generator. In mentioned construction, battery is used as energy buffer and combustion engine is used more as emergency power supply, and is turned on when battery is depleted. In other condition, power generator can be turned off, without reducing power of transmission parameters, except its range. Investigation was divided on two stages. At first stage generator, charging unit and battery were placed outside the vehicle. One piston power generator was feed by Diesel fuel. Fuel consumption of power generator was recorded from AVL fuel balance and energy parameters were recorded by power line analyser of BMR Company. Generator was connected to the direct current power plant. 70 Ah and 48 DC Lithium-polymer battery was charged from the power plant. After charging cycle, small water resistor was used to discharge the battery. Power parameters of discharged battery were measured. This enable to measure balance form tank to the battery. Second stage of the energetic balance determination was to measure internal resistances of vehicle power transmission from current inverter/converter connected to the engine and through the transmission up to the wheels of the vehicle. Power loss of energy at different speed of vehicle wheels without ground contact was measured in respect of power consumption. The series hybrid transmission is consider less efficient than parallel but because of specific configuration of power transmission, it was possible to reach higher efficiency

Opis:: The article presents modeling of loading platforms for the automated command system of a field artillery battalion mounted on the light wheeled chassis. According to the operational requirements, the field battalion should be tailored to be transported by the transport aircraft C-130E Hercules, which requires limiting the weight and dimensions of vehicles. Since a vehicle cab height is equal with the exact centimeter precise to the aircraft cargo bay height, it is necessary to reduce the relevant vehicle height by lowering the tire pressures in order to obtain an adequate margin.
