Isihlungi sikaMann+Hummel sezinto zangaphakathi zezimoto sibe yingxenye yezifundo zochwepheshe zaseNyuvesi yase-Heidelberg ezibonise ukuthi isihlungi sehlisa ukugcwala kwe-nitrogen dioxide ngaphakathi kwemoto ngaphezu kwama-90%.

Ukuvikela abahlali bamakhabethe kumagesi ayingozi kanye nephunga elibi, isihlungi siqukethe cishe u-140 g wekhabhoni esebenza kakhulu. Lokhu kunohlaka olunezimbotshana oluhlanganisa u-140,000 m² yendawo engaphakathi, eqhathaniswa nobukhulu bezinkundla zebhola likanobhutshuzwayo ezingama-20.

Lapho nje ama-nitrogen oxide efika kukhabhoni ecushiwe, amanye abhajwa ezimbotsheni futhi akhangiswe lapho. Enye ingxenye isabela nokuswakama okusemoyeni, ikhiqize i-nitrous acid, nayo ehlala kusihlungi. Ngaphezu kwalokho, i-nitrogen dioxide enobuthi iyancipha ibe yi-nitrogen monoxide ngendlela esabela ngayo. Lokhu kusho ukuthi isihlungi sezinhlayiyana ze-Mann+Hummel singanciphisa amagesi ayingozi namaphunga angemnandi ngaphezu kuka-90% uma kuqhathaniswa nesihlungi sezinhlayiyana ezivamile.

Isihlungi siphinde sivimbe uthuli olucolekile futhi izihlungi ezisebenza nge-biofunctional zigcina izinto eziningi ezingezwani nokudla kanye nama-aerosol egciwane kuyilapho ukunamathela okukhethekile kuvimbela ukukhula kwamagciwane kanye nesikhunta.
