Dziwani zambiri za nyumba za turbo turbine

Kuwongolera kwa magwiridwe antchito a injini zoyatsira mkati kwadzetsa kutsika kwa kutentha kwa mpweya wotuluka.Kulimbitsa munthawi yomweyo malire a utsi kumafuna njira zovuta zowongolera utsi, kuphatikizapambuyo pa chithandizoamene mphamvu yake imadalira kwambiri kutentha kwa mpweya wotuluka.

Mipanda iwiri yotulutsa mpweya nditurbine nyumbama modules opangidwa kuchokera ku zitsulo zachitsulo akhala akugwiritsidwa ntchito mu injini za petulo kuyambira 2009. Amapereka kuthekera kwa injini zamakono za Dizilo kuti achepetse mpweya wa zowonongeka ndi mafuta.Amaperekanso ubwino potengera kulemera kwa chigawo ndi kutentha kwa pamwamba poyerekeza ndi zigawo zachitsulo.Zotsatirazi zikusonyeza kuti kugwiritsa ntchito makina opangira mpweya wa mpweya wa mpweya kungapangitse kuchepetsa mpweya wa HC, CO, ndi NOx pamphepete mwa nyanja. 20 mpaka 50%, kutengera kapangidwe ka injini, kalasi ya inertia yamagalimoto, komanso kayendedwe ka magalimoto, poyerekeza ndi njira yopopera yoyambira yomwe ili ndi zida zanthawi zonse zotulutsa chitsulo ndi turbine nyumba.

Fig. 2: Use of three-dimensional computation procedures for simulating the airflow and the mechanical structural loads to optimize turbocharger performance The turbochargers must retain the required characteristics throughout their entire service lives. To this end, MTU works with three-dimensional computation procedures to simulate the airflow and the mechanical structural loads.

Pogwiritsa ntchito njira zokongoletsedwa za EGR, kuwonjezeka kwa injini kunja kwa NOx kungaloledwe pogwiritsa ntchito kutembenuka kwapamwamba kwa NOx mu SDPF.Zotsatira zake, mphamvu yopulumutsa mafuta yofikira ku 2% idawonedwa mu WLTP ndipo Kupititsa patsogolo kwaukadaulo wamainjini a dizilo ndikofunikira kuti akwaniritse malamulo okhwima a gasi komanso kuchepetsa kutulutsa kwa CO2 munthawi imodzi.Ku EU ndi maiko ena, kuwongolera njira zovomerezeka, monga Worldwide harmonized Light Cars Test Procedure (WLTP) ndi malire a zotulutsa zenizeni (RDE), ndizotsimikizika kukhazikitsidwa.Kukhazikitsidwa kwa njira zokhwimazi kudzafuna kuwongolera kowonjezereka kwa machitidwe.Kuphatikiza pa DOC ndi diesel particulate filter (DPF), injini zamtsogolo zidzakhala ndi NOx pambuyo pa chipangizo chothandizira monga NOx yosungirako catalyst kapena njira yochepetsera kuchepetsa.
