i-diesel catalyst

I-catalytic converter iyithuluzi elisetshenziselwa ukunciphisa ukukhishwa kwezingxenye eziyingozi kumagesi okukhipha umoya futhi liphinde lisetshenziswe ezinjinini zikadizili.

Sekuyiminyaka engaphezu kwengu-20 abakhiqizi bezimoto besebenzisa iziguquli ze-catalytic ezinhlelweni zokukhipha umoya wezinjini zikaphethiloli. Njengoba i-catalytic converter iyithuluzi elisetshenziselwa ukunciphisa ukukhishwa kwezingxenye eziyingozi zibe amagesi okukhipha umoya, iphinde isetshenziswe ezinjinini zikadizili.

Injini kadizili ikhipha umule, ama-hydrocarbon, i-sulphur dioxide, i-nitrogen oxides nezinsimbi: i-calcium, i-magnesium, insimbi ne-zinc ngenxa yesimiso sokusebenza kanye nophethiloli osetshenzisiwe. I-oxidation catalyst esetshenziswa kabanzi inganciphisa ukukhishwa kwesulfure dioxide ngamaphesenti angama-98, ukukhishwa kwe-hydrocarbon ne-carbon monoxide ngamaphesenti angaphezu kuka-80.

Izinga le-Euro IV belilokhu lisebenza kusukela ngo-2005. Ezinhlelweni zokukhipha umoya wezinjini zikadizili, ukufakwa kwama-catalyst kanye nesihlungi sezinhlayiya kuzoba yisidingo, mhlawumbe i-catalyst eyengeziwe izokwengezwa ukuze kuncishiswe ama-nitrogen oxide.
