Ngingazi kanjani ukuthi injini yami ayiqhumi?

Uma inhlansi ivuthela igesi eguquguqukayo ngaphakathi kwenjini, umklamo ovikela ukuqhuma uqukethe ukusha kwangaphakathi ukuvimbela ukuqhuma okukhulu noma umlilo. Injini evikela ukuqhuma iphawulwe ngokucacile nge-nameplate ekhomba ukuthi ifanelekela indawo ethile enobungozi.
Kuye ngokuthi i-ejensi eqinisekisa imoto injani, i-nameplate izobonisa ngokucacile indawo enobungozi Isigaba, iSigaba, kanye neQembu okufanele imoto isebenzise. Ama-ejensi angaqinisekisa ama-motor omsebenzi onobungozi yi-UL (United States), i-ATEX (European Union), kanye ne-CCC (China). Lawa ma-ejensi ahlukanisa izindawo eziyingozi ngeSigaba - esichaza izingozi ezingaba khona emvelweni; Isigaba - esikhomba amathuba okuba ingozi ibe khona ngaphansi kwezimo zokusebenza ezijwayelekile; kanye neQembu - elikhomba izinto ezithile ezikhona.

Inqubo ye-UL ibona izigaba ezintathu zezingozi: Amagesi avuthayo, umusi noma uketshezi (Isigaba I), uthuli oluvuthayo (Isigaba II), noma imicu evuthayo (Isigaba III). Isigaba 1 sibonisa ukuthi izinto eziyingozi zikhona ngaphansi kwezimo zokusebenza ezijwayelekile, kanti iSigaba 2 sibonisa ukuthi izinto cishe azikho ngaphansi kwezimo ezijwayelekile. Iqembu lizokhomba ngqo izinto eziyingozi ezikhona, njengezinto ezivamile zeSigaba I ze-Acetylene (A), i-Hydrogen (B), i-Ethylene (C), noma i-Propane (D).

I-European Union inezidingo ezifanayo zesitifiketi ezihlanganisa izindawo ngezindawo. Izindawo 0, 1, kanye no-2 zimiselwe igesi nomhwamuko, kanti izindawo 20, 21, kanye no-22 zimiselwe uthuli nefayibha. Inombolo yendawo ichaza amathuba okuba izinto zibe khona ngesikhathi sokusebenza okuvamile lapho indawo 0 no-20 iphezulu kakhulu, 1 no-21 iphezulu futhi ijwayelekile, kanye no-2 no-22 iphansi.

Kusukela ngo-Okthoba 2020, iShayina idinga ukuthi izinjini ezisebenza ezindaweni eziyingozi zibe nesitifiketi se-CCC. Ukuze kutholakale isitifiketi, umkhiqizo uhlolwa yinhlangano yokuhlola eqinisekisiwe ngokwezidingo ezithile ezibekwe uhulumeni waseShayina.
Kubalulekile ukuhlola ipuleti legama lenjini ukuthola izidingo ezithile, izingozi ezikhona, kanye nezinye izinto ezicatshangelwayo zemvelo ukuze kunqunywe ukuthi injini ifanelana kahle yini nokuqhuma. Ukuqokwa kokuqina kokuqhuma kubonisa izinhlobo zezingozi ezifanela leyo moto ethile. Ukusebenzisa imoto engakwazi ukuqhuma endaweni eyingozi lapho ingakalwanga khona ngokuqondile kungaba yingozi.
