1.In iji nweta elu iyuzucha gas dị ọcha ọnụego na ibelata components nke (CO) carbon monoxide, (HC) hydrocarbons na (NOx) nitrogen oxides na iyuzucha gas, EFI ugbo ala ga-eji atọ catalytic converters.Otú ọ dị, iji rụọ ọrụ nke ọma na-eji ụzọ atọ catalytic converter, ọ dị mkpa ijikwa n'ụzọ ziri ezi nke ikuku-mmanụ ruru ka ọ na-mgbe niile nso theoretical ikuku-mmanụ ratio.A na-etinyekarị ihe na-eme ka ọ dị n'etiti ihe mkpofu na ihe mkpuchi.Ihe mmetụta oxygen nwere njirimara na voltaji mmepụta ya na-agbanwe na mberede na nso nsonye ikuku-mmanụ (14.7: 1).A na-eji njirimara a chọpụta ọnụọgụ oxygen dị na gas iyuzucha ma nyeghachi ya na kọmpụta iji chịkwaa oke ikuku na mmanụ.Mgbe ezigbo ikuku-mmanụ ọkụ na-abawanye elu, ntinye nke ikuku oxygen na ikuku ikuku na-abawanye na ihe mmetụta oxygen na-agwa ECU nke ọnọdụ siri ike nke ngwakọta (obere ike electromotive: O volts).Mgbe oke ikuku-mmanụ ahụ dị ala karịa usoro ikuku-mmanụ ọkụ, ntinye nke oxygen na ikuku ikuku na-ebelata, a na-agwakwa ọnọdụ ikuku oxygen (nnukwu electromotive ike: 1 volt) na kọmpụta ECU.

2.ECU na-ekpe ikpe ma ikuku-mmanụ ọkụ dị ala ma ọ bụ dị elu dị ka ike electromotive dị iche site na ihe mmetụta oxygen, ma na-achịkwa oge ịgbanye mmanụ ọkụ n'otu aka ahụ.Otú ọ dị, ọ bụrụ na ikuku oxygen na-ebufe adịghị mma na mmepụta electromotive ike adịghị mma, kọmputa ECU enweghị ike ịchịkwa oke ikuku na mmanụ ụgbọala.Ya mere, ihe mmetụta oxygen nwekwara ike mejupụta maka njehie nke ikuku-mmanụ ọkụ kpatara site na iyi nke igwe na akụkụ ndị ọzọ nke usoro EFI.Enwere ike ikwu na ọ bụ naanị ihe mmetụta "nwere ọgụgụ isi" na usoro EFI.

3.The ọrụ nke ihe mmetụta bụ iji chọpụta ma e nwere ngafe oxygen na iyuzucha gas nke engine mgbe combustion, ya bụ, oxygen ọdịnaya, na tọghata oxygen ọdịnaya n'ime a voltaji mgbaàmà na-ebufe ya na engine kọmputa, otú. na engine nwere ike ghọta mechiri emechi-loop akara na ngafe ikuku ihe dị ka ihe mgbaru ọsọ;Gbaa mbọ hụ na onye ntụgharị catalytic ụzọ atọ nwere oke ngbanwe kachasị maka hydrocarbons (HC), carbon monoxide (CO) na nitrogen oxides (NOX) n'ime gas na-ekuku, wee gbanwee ma sachaa mmetọ ndị ewepụrụ ruo oke.
