“…Such conditions allow to estimate the degree of emission hazard of special vehicles and their engines during typical activities. The results of homologation tests of HDV (heavy duty vehicle) vehicles do not allow to assess their actual emission of harmful substances to the atmosphere [1,3,8].…”

“…This characteristic replaced the entire road cycle with several measurement points on the engine operation characteristics and enabled the determination of average mileage fuel consumption. Although this characteristic does not take into account the dynamic properties of the motor, defined by the dependence: control-torque, the published results of optimization with the use of time density characteristics show that such simplification is acceptable [8].…”

“…Warunki takie pozwalają oszacować stopień zagrożenia emisyjnego pojazdów specjalnych i ich silników podczas typowych działań. Wyniki z testów homologacyjnych silników pojazdów HDV (heavy duty vehicle) nie pozwalają ocenić ich rzeczywistej emisji substancji szkodliwych do atmosfery [1,3,8]. Prezentowane w artykule wyniki badań emisji spalin w postaci pomiarów stężenia: CO, HC, NOx, CO 2 , pomiarów masy, rozkładu oraz liczby cząstek stałych, podzielono na kilka etapów, do których zaliczono: 6. pomiary emisji podczas rozruchu silnika:…”

The paper presents results of the analysis of emissivity of exhaust gases, based on tests special vehicles under difficult terrains conditions. There was tested Armoured Combat Vehicle "ROSOMAK", what was designed as a modular vehicle to transport people and equipment as well as combat uses too. The research were carried out on both the new vehicles, as well as the already operated on two different military training fields in Poland (Siemianowice Śląskie, Sulejówek).

“…Both one dimensional (GT POWER) and computational fluid dynamics simulations of diesel engines with the combustion chambers insulated with TBC show increased fuel efficiency, 8,9 while experiments show varying results. In some experiments, fuel efficiency improvements of 1–6% have been achieved, 2,3,5 while in others no improvement or even a decrease in fuel efficiency were reported. 10–12 There are various possible reasons for the failure to obtain the expected benefits with TBCs in diesel engines.…”

Thermal barrier coatings have the potential to improve the fuel efficiency of heavy-duty diesel engines by reducing heat losses. A method for in-situ measurement of heat flux from the combustion chamber of a heavy-duty diesel engine has been developed and was used to study the running-in behaviour of different thermal barrier coating materials and types of microstructures. The in-situ measurements show that the initial heat flux was reduced by up to 4.7% for all investigated thermal barrier coatings compared to a steel reference, except for an yttria-stabilized zirconia coating with sealed pores that had an increase of 12.0% in heat flux. Gd2Zr2O7 had the lowest initial value for heat flux. However, running-in shows the lowest values for yttria-stabilized zirconia after 2–3 h. Potential spallation problems were observed for Gd2Zr2O7 and La2Zr2O7.
