1️⃣ Uxinzelelo lokuthatha okonakeleyo kunye nenzwa yobushushu
Uhlalutyo lwesizathu: Isignali yoxinzelelo lwe-intake ayiqhelekanga, kwaye i-ECU ayikwazi ukufumana ulwazi oluchanekileyo lokuthatha, olukhokelela kwi-injection ye-fuel engaqhelekanga.Ukutshisa oku akwanelanga, injini iyacotha, kwaye kuphuma umsi omnyama ngexesha lokufakwa kwepetroli.Iingxaki kunye noqhagamshelo lwentambo yokubopha kunye nokusilela koluvo kunokubangela oku kungaphumeleli.
Isisombululo: Jonga uxinzelelo lomoya wokungena kunye nenzwa yobushushu.
2️⃣ Ukonakala kwenzwa yobushushu bamanzi
Uhlalutyo lwesizathu: xa i-sensor yeqondo lokushisa lamanzi ihluleka kwaye i-ECU ibona ukuba umqondiso wokuphuma kweqondo lokushisa lamanzi alikholeleki, ixabiso elithatha indawo lisetyenziswa.I-ECU inciphisa i-torque ye-injini ngenjongo yokukhusela injini.
Isisombululo: khangela inzwa yobushushu bamanzi.
3️⃣ Ukonakala kwenzwa yoxinzelelo lweoyile
Uhlalutyo lwesizathu: i-probe ye-oil pressure sensor yonakaliswe kakhulu, i-ECU ibona ukuba i-sensor ye-oyile ye-oil ayixhunyiwe, kwaye ixabiso elibonisiweyo lesixhobo liyixabiso langaphakathi le-ECU.
Isisombululo: jonga inzwa yoxinzelelo lweoyile.
4️⃣ Uqhagamshelwano olubi lwe-OBD socket terminal
Uhlalutyo lwesizathu: i-terminal ye-OBD ye-socket iphuma, ibangele uqhagamshelwano olubi, kunye nesixhobo sokuxilonga kunye ne-ECU ayikwazi ukunxibelelana.
Isisombululo: khangela i-terminal ye-socket ye-OBD.
5️⃣ I-nitrogen kunye ne-oxygen sensor wire harness isiphaluka esifutshane
Uhlalutyo lwesizathu: i-nitrogen kunye ne-oxygen sensor harness igugile, i-short circuited and grounded, kunye ne-nitrogen kunye ne-oxygen sensor ayikwazi ukusebenza ngokuqhelekileyo, okubangelwa ukukhutshwa okugqithisileyo, umda we-injini ye-torque kunye ne-alamu yenkqubo.
Isisombululo: khangela i-wire harness ye-nitrogen kunye ne-oxygen sensor.
6️⃣ Ukuthunyelwa konyango lokufudumeza umonakalo webhokisi
Uhlalutyo lwesizathu: Bopha impazamo yesekethe evulekileyo.
Isisombululo: khangela kwaye ulungise i-harness yokufudumeza ibhokisi ye-relay.
7️⃣ Isoftware esezantsi yesixhobo ayilunganga kwaye ayithumeli isignali yesantya sesithuthi
Uhlalutyo lwesizathu: ngexesha lokuqhuba, isignali yesantya sesithuthi esithunyelwe ngesixhobo ngokukhawuleza siyehla kwi-0. Ukutshintshwa kwesantya semoto kukhokelela ekutshintsheni kwe-ECU yokulawula umthamo weoli, okubangelwa ukuchithwa kwepetroli ngokukhawuleza.
Isisombululo: hlaziya isixhobo kuguqulelo lwamva nje
8️⃣ Ukuvala umbhobho wokubuyisela urea wenkqubo ye-SCR
Uhlalutyo lwesizathu: i-sundries kumbhobho wokubuyiswa kwe-urea ivaliwe, okubangela ukusilela kwenkqubo yokufaka i-urea ngokuqhelekileyo, ukukhutshwa kudlula umgangatho, umda we-injini ye-torque, kunye ne-alamu yenkqubo.
Isisombululo: khangela umbhobho wokubuyisela urea.
9️⃣ Isenzeko se-terminal socket yesidibanisi sombhobho wokufudumeza we-urea reflux
Uhlalutyo lwesizathu: Ukungaphumeleli kwesinxibelelanisi sombhobho wokubuyisela urea wokufudumeza.
Isisombululo: lungisa i-terminal kwaye uqhagamshele kwakhona iplagi.
