Gịnị bụ a catalytic Ntụgharị

All oge a ụgbọ ala iyuzucha usoro na-agụnye a catalytic Ntụgharị. Nke a ngwaọrụ bụ iji belata umu anwuru nke na-emerụ bekee site iyuzucha, haruru ka ikuku. The catalytic Ntụgharị eji dị dizel ike nkeji, nakwa dị ka mmanụ ụgbọ ala. Ya guzosie ike ma ọ bụ ozugbo n'azụ iyuzucha manifold, ma ọ bụ ozugbo na mofla. The neutralizer nke iyuzucha, haruru na-agụnye a ụgbọelu unit, ihe kwes mkpuchi ihe nke ụlọ.

Ha elu na-ntekwasa na pụrụ iche bekee, akpali (palladium, platinum na rhodium). Ndị a ọcha, e nwere ihe osooso nke chemical Jeremaya mere.

Palladium na platinum bụ ọxịdashọn mkpali. Ha na-enye ọxịdashọn nke hydrocarbons na, ya, na-akwalite na ntughari nke carbon monoxide, carbon dioxide na mmiri vepo. A Mbelata mkpali bụ rhodium. Ọ na-eji maka mbenata nitrogen oxides n'ime adịghị njọ nitrogen. Ọ na-enyo na atọ ụdị nke akpali na iyuzucha, haruru na-ebelata ọdịnaya nke atọ dị iche iche na-emerụ bekee. Ya mere, ndị dị otú ahụ a na ngwaọrụ a na-akpọ a atọ ụzọ catalytic Ntụgharị.

The akpali bụ nnọọ irè na mbenata iyuzucha gas toxicity ma si otú ọ nweghị mmetụta na engine ike na mmanụ ụgbọala oriri. Na ngwaọrụ a azụ mgbali abawanye ubé dị ka a N'ihi nke a ụgbọala ike unit tụfuru 2-3 lita. a. Theoretically iyuzucha mkpali nwere ike ruo mgbe ebighị ebi, n'ihi na dị oké ọnụ ahịa metal n'oge chemical Jeremaya mere gwusia. Otú ọ dị, dị ka omume-egosi, ndụ nke ndị a na ngwaọrụ nwere ya ókè.
