Pokazano charakterystyczne cechy układu zasilania powietrzem silnika UTD-20 bojo-wego wozu piechoty BWP-1. Przedstawiono wyniki badań skuteczności filtracji i oporów przepływu standardowego filtru powietrza BWP-1. Wykazano konieczność zmian kon-strukcyjnych układu zasilania powietrzem silnika UTD-20.
Zaproponowano i wykonano system filtracji powietrza wlotowego do silnika BWP-1 w postaci filtru przegrodowego. Określono charakterystyki skuteczności filtracji ϕ = f(mp) i oporu przepływu ∆p = f(mp), ∆p = f(QG) oraz chłonność pyłową dla zaprojektowanego filtru przegrodowego. Określono na hamowni silnikowej wpływ zmodernizowanego filtru powietrza oraz wzrostu dawki paliwa na parametry efektywne silnika. Wyznaczono wpływ proponowanych zmian na przebieg momentu indykowanego i efektywnego podczas swobodnego rozpędzania silnika oraz na jego sprawność mechaniczną.
THE EXPERIMENTAL RESEARCH OF AIR SUPPLY SYSTEM MODIFICATION ON INLET AIR FILTRATION EFFICIENCY AND MILITARY VEHICLE ENGINE EFFECTIVENESS IMPROVEMENT
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 ϕ = f(mp) and flow drag ∆p = f(mp), ∆p = f(QG) for designed air filter were determined. Absorbency of filter for air nominal stream of engine BWP-1 was specified. The influence of modernized air filter and fuel dose increase on engine effective parameters were determined. There were determined the influence the proposed changes on indicated and effective torque during engine free acceleration and its mechanical efficiency as well. (...)
