Opis:: Specific features of air inlet system of BWP-1 vehicle UTD-20 engine are shown. The tests results of filtration efficiency and air flow drag for BWP-1 vehicle air filter standard version are presented. The necessity of UTD-20 engine air supplying system constructional changes are proved. The inlet air filtration system for BWP-1 engine with the porous filter was proposed and performed. The characteristics of the air purification efficiency (fi=f(mp) and flow drag Delta p- f(mp) Delta p= f(Omega c) for designed air filter were determined. Absorbency of filter for air nominal stream of engine BWP-1 was specified. The designed and executed partition air filter was subjected to comparative tests on an engine test bench. The influence of modernized air filter and fuel dose increase on engine effective parameters were determined. The tests covered comparison of effective parameters (determined for maximum load) of a UTD-20 engine equipped with a standard air filter (variant 1), a modernized air filter (variant 2) and additionally, for the modernized air filter, with injection pump with fuel dose increased (variant 3). There were determined the influence the proposed changes on indicated and effective torque during engine free acceleration and its mechanical efficiency as well.

Opis:: One of the recent trends in heavy-duty engines has been the introduction of common rail injector with hydraulic amplifier (HADI − Hydraulically Amplified Diesel Injector) capable of considerable fuel pressure injection increase in reference to fuel pressure prevailing in rail of common rail fuel system. An example of a solution of this type of injectors is the two-valve CRIN4 injectors manufactured by Bosch. They allow the control of the fuel flow rate during injection process and therefore have an impact on the combustion process. In this article, advantages related to their use are described, which allow the engines with such injectors to meet the limits of the admissible content of toxic compounds in the exhaust gases defined in the EURO VI standard. An experimental study of the operation of the Bosch IV generation common rail system was performed on the Mercedes-Benz Actros. During measurement engine load, engine speed, waveforms (electric currents) controlling operation of the selected injectors, fuel pressure in the rail and the control current of high pressure pump control valve (metering unit) were registered. Interpretations of recorded waveforms were made, indicating the areas of application of the various modes operation. The use of CRIN4 injectors for the rapid reduction of fuel pressure in rail was observed, which supports the metering unit (ZME) for pressure control.

Opis:: The methodology of measuring the vibration signal recorded on the casing of wheeled armoured vehicle ROSOMAK driving axis is presented. The study was performed on a test bench for different transmission conditions. A preliminary analysis of the frequency spectra vibration signals recorded. The test stand allows investigation of the differential axle gears under load similar to load during duty operation. It was possible by using the combustion engine and gearboxes and load transmission by using the dynamometer break. Have been described. Three methods of attaching acceleration sensors to differential gears: using screws, magnetic washers and probe handle. The results of comparisons of measurement results obtained using these methods. Finally, the sensors was mount by using the screw connections. Selected positions and points of temperature and vibration measures were described. Values of characteristic frequencies of differential axle gears vibration by moving the drive torque through these boxes were calculated. The spectra of the vibration signal determined during testing gearboxes were shown. It was state that of amplitude-frequency vibration spectra of signals recorded at selected points of differential axle gears casing are clearly visible characteristic frequencies but the vibration the bridge gear unit bridges distorted by vibration of the internal combustion engine and gearboxes. In a further stage of research should be included much larger number of the driving axis differentials investigated in various states of well-known technical conditions and should be lead accord to requirements of the active diagnostic experiment.

Opis:: The methodology of research and the inspection of the main transmission gearboxes of multi axles armoured vehicle ROSOMAK under operating conditions are described in this article. Tests are carried out on the bench to allow force transmission changes to the extent similar to the loads that occur during vehicle operation. Transmission gear boxes are driven by an internal combustion engine 359 through a reducer (standard engine gearbox). This reducer increase torque and decrease shaft speed similar to condition in the vehicle. On the other side of the transmission, multiplying gearbox coupled with a brake dynamometer were placed. It increases speed according to requirements of the work field of the dynamometer W-230. The combustion engine made possible to measure vibration of transmission gearboxes under the high torque. The torque is greater than obtainable by using electric motors. The value of the inertia moment loading axle shaft was determined using a simplified kinematic diagram. During the tests, vibration were measured at selected points of the housing using different methods of attachment of vibration transducers. First, the screw for assembling the vibration sensor was glued to the hull of gearbox. Second, the sensor was connected with gearbox by permanent magnets. Third, the sensor was used as a hand probe. The results of vibration measured by these methods were compared. Temperature of the gearbox was also measured by using thermocouples and thermovision methods. Selected results are presented and analysed of vibration transmission and its temperature at selected working conditions.
