I-CNG (igesi yemvelo ecindezelwe) - Autorubic
Ngaphansi kwesifinyezo esithi CNG (Compressed Natural Gas) yigama elithi igesi yemvelo ecindezelwe. I-CNG inguphethiloli we-hydrocarbon, ingxenye yawo eyinhloko i-methane (80-98% ngevolumu). Imbiwa ikakhulukazi kanye namafutha. Ngokwephesenti le-methane, igesi yemvelo ihlukaniswe izigaba ezimbili: ephezulu (87-99% methane) kanye nephansi (80-87% methane). I-CNG yekhwalithi ephezulu isetshenziswa eziteshini zikaphethiloli ngenxa yokusebenza kahle kwamandla okuvutha. Ngenxa yokuthi izinqolobane zegesi yemvelo zilinganiselwa ukuthi zingaphezu kokuphindwe kabili kwalezo zikawoyela, ishibhile, zinezinga eliphezulu le-octane, kanye namazinga aphansi kakhulu okungcola kwegesi ephumayo (CO) uma kuqhathaniswa nodizili noma uphethiloli.2 akukhox 25% nokuqukethwe kwe-CO kuze kufike ku-50%), kungachazwa njengophethiloli olungele imvelo futhi othembisayo.
Igumbi elincishisiwe lemithwalo ngenxa yendawo yethangi le-LNG, kanye nenethiwekhi encane yeziteshi zokugcwalisa, ivimbela ukwanda okubaluleke kakhulu. Ukusetshenziswa kwezimoto zegesi yemvelo kuboniswa ngo-kg ngamakhilomitha ayi-100, kanti izimoto ezijwayelekile ezifana neRenault Scenic, Fiat Doblo noma i-VW Passat, eziguqulwe efemini kule drive, ukusetshenziswa kwegesi okuphakathi kuka-5 no-8 kg. .. . okwe-100 km.
