Ukuhlolwa Kwegesi Nokukhanya ku-ITV (Ingxenye II)

NgoLwesihlanu olwedlule sikhulume nge Ukuhlolwa kwegesi ezimotweni zikaphethiloli okwenziwa ku-ITV. Namuhla, sizokwenza okufanayo ngezimoto zikadizili.

Kulokhu, kubizwa I-Opacity Test futhi iyakala, njengoba negama layo liphakamisa, ukufiphala kwamagesi aphumayo nge-opacimeter.. Ngamanye amazwi, okukalwa kulokhu kuhlolwa yikhabhoni noma intuthu emnyama ephuma ekukhipheni.

Uma lapho ishaya i-acceleration enamandla, imoto yethu ikhipha intuthu emnyama, ingase ingaphumeleli ekuhlolweni kwe-opacity. Esinye isincomo ukuthi, uma sisendleleni eya ku-ITV, kuwukunikeza injini injabulo encane futhi cindezela amagiya ambalwa endaweni ebomvu. Ngalokhu sizokwazi ukwenza ukuhlanza okuzohambisana nokuhlolwa abakwenzayo ku-ITV.

Kuyini ukuhlolwa kwegesi ye-ITV?

La ukuhlolwa kwegesi Yokuhlolwa Kwezimoto Ngobuchwepheshe (i-ITV) inqubo eyenziwa ngesikhathi sokuhlolwa okuphoqelekile ngezikhathi ezithile ukuze kuhlolwe ukukhishwa kwegesi yezimoto. Inhloso yalokhu kuhlola iwukuqinisekisa ukuthi amagesi akhishwa yi-exhaust ahambisana nemikhawulo emiswe imithetho yamanje yokuvikelwa kwemvelo nokulawula ukungcola.

Ngesikhathi sokuhlolwa kwegesi ye-ITV, i-analyzer yegesi isetshenziselwa ukukala nokuhlaziya ukugxila kwamagesi ahlukene akhona imfucumfucu yemotonjenge-carbon dioxide (CO2), i-carbon monoxide (CO), ama-hydrocarbon angashisiwe (HC) nama-oxide e-nitrogen (NOx).

Imoto ibekwe ebhentshini elikhethekile lokuhlola lapho ipayipi yokukhipha ixhunywe ku-analyzer yegesi. Izilinganiso zenziwa ngaphansi kwezimo ezahlukene ze ukusheshisa kanye ne-revs ukulingisa izimo zokushayela ezahlukene. Ngokusekelwe emiphumeleni etholiwe, kuyahlolwa ukuthi ingabe ukukhishwa kwemoto kuyahambisana yini nemikhawulo emiswe imithethonqubo ehambisanayo.

Uma kwenzeka amanani we okukhishwayo kweqa imikhawulo evunyelwe, imoto ngeke iphumelele ekuhlolweni kwegesi ye-ITV futhi kuyodingeka ukuba kwenziwe ukulungisa okuhambisanayo noma ukulungisa ukuze kuncishiswe ukungcola kanye nokuhlangabezana nezindinganiso ezidingekayo ngaphambi kokuhlolwa futhi.

Ukuhlolwa kwegesi ye-ITV kubalulekile ukuze kuqinisekiswe ukuthi izimoto ukuthobelana nezidingo zemvelo kanye neqhaza ekunciphiseni ukungcoliswa komoya.

Amagesi e-diesel exhaust

I-Los amagesi akhishwayo ngenjini ye-diesel iqukethe inhlanganisela yezingxenye ezihlukahlukene, kuhlanganise:

• I-Carbon dioxide (CO2): Iyingxenye eyinhloko yamagesi aphumayo enjini kadizili. I-CO2 iyigesi ebamba ukushisa futhi inomthelela ekufudumaleni komhlaba.
• I-Carbon monoxide (CO): Igesi engenambala nengenaphunga ekhiqizwa ngesikhathi sokushiswa kukaphethiloli okungaphelele. I-CO inobuthi futhi ingaba yingozi ekugxilweni okuphezulu.
• I-nitrogen oxides (NOx): Ama-nitrogen oxide, ahlanganisa i-nitrous oxide (NO) ne-nitrogen dioxide (NO2), akhiwa ngesikhathi sokusha emazingeni okushisa aphezulu. Zingamagesi angcolisayo anomthelela ekwakhekeni kwentuthu futhi angabangela izinkinga zokuphefumula nezemvelo.
• Ama-hydrocarbon angashisiwe (HC): Ama-hydrocarbon angashisiwe ayizinhlanganisela eziphilayo ezishintshashintshayo (VOCs) ezingashiswanga ngokuphelele ngesikhathi sokusha. Lezi zinhlanganisela zingaba nomthelela ekwakhekeni kwentuthu futhi zibe nemiphumela engemihle kukhwalithi yomoya.
• Izinhlayiya eziqinile: Izinjini zikadizili ziphinde zikhiphe izinhlayiya ezinhle eziqinile, ezaziwa ngokuthi yi-particle noma umule. Lezi zinhlayiya ziyingozi empilweni yomuntu futhi zingabangela izinkinga zokuphefumula, ikakhulukazi ekugxilweni okuphezulu.

Inqubo yokuhlola igesi yemoto kadizili

Inqubo yokwenza lokhu kuhlola ihluke kancane kuleyo echazwe ezimotweni zikaphethroli. Okokuqala, kubalulekile ukuthi izinga lokushisa lenjini lisondele ku-80º C. Ngaphambi kokwenza isivivinyo, umhloli kufanele alinganise izinga likawoyela ukuze ahlole ukuthi lilungile yini, uma lingekho phakathi kokuncane nokuphezulu, ukuhlolwa akukwazi. kwenziwe.

Ukuhlolwa, njengomthetho ojwayelekile, Kumele yenziwe ngumhloli we-ITV futhi ihlanganisa ukusheshisa imoto ngokugcwele, ezimotweni ezizenzakalelayo izosheshisa kancane kancane, cishe u-2/3 wengqikithi. Ukusheshisa kuzovame ukuphindwa izikhathi ezimbalwa ukuze uthole umphumela othembekile.

Amanani aphezulu alolu hlolo, ezimotweni ezibhaliswe ngaphambi kwe- 1 kaJulio we-2008, ingu-3,0 m-1 ezimotweni ezine-turbo kanye no-2,5 ​​m-1 kulabo abangenayo. Kuzo zonke izimoto ezibhaliswe ngemva kwalolo suku, inani eliphakeme elivunyelwe ngu-1,5 m-1.

Uma kwenzeka kudlula amanani esisanda kuwasho, imoto izonqatshwa futhi kufanele idlule i-ITV futhi. Phakathi kokunye, okungase kube imbangela kungaba ukuthi sinesihlungi somoya esingcolile. Njengoba sishilo ngaphambili, ngimane ngivuse imoto kancane futhi ukukhama amagiya ambalwa ngokuvamile kwanele ukuphumelela ukuhlolwa.

Ulwazi olwengeziwe - Kufanele ngidlule kangaki i-MOT?
