mmanụ dizel mkpali

Ihe ntụgharị catalytic bụ ngwaọrụ a na-eji ebelata ikuku nke ihe ndị na-emerụ ahụ n'ime gas na-ekpochapụ ma na-ejikwa ya na mmanụ dizel.

Kemgbe ihe karịrị afọ 20, ndị na-emepụta ụgbọ ala na-eji ihe ntụgharị catalytic na sistemu ikuku nke mmanụ ụgbọala. Ebe ọ bụ na ihe ntụgharị catalytic bụ ngwaọrụ a na-eji ebelata ikuku nke ihe ndị na-emerụ ahụ n'ime ikuku ikuku, a na-ejikwa ya na mmanụ dizel.

Injin mmanụ dizel na-ebupụta soot, hydrocarbons, sulfur dioxide, nitrogen oxides na ọla: calcium, magnesium, iron na zinc n'ihi ụkpụrụ nke ọrụ na mmanụ eji. Ihe na-akpata oxidation nke a na-ejikarị eme ihe nwere ike ibelata ikuku sọlfọ dioxide site na pasentị 98, ikuku hydrocarbon na carbon monoxide ihe karịrị pasenti 80.
