Kwabo bafuna iindlela zokuphucula ukusebenza kwemoto, kufuneka udibane nombonoUkucima i-EGR.Kukho amanqaku ekufuneka uzazi kwangaphambili ngaphambi kokuguqula ikhithi yokucima i-EGR.Namhlanje siza kugxila kwesi sihloko.
1.Yintoni i-EGR kunye ne-EGR Cima?
I-EGR imele i-exhaust gas recirculation.Le yiteknoloji esetyenziswa kwiinkqubo yokukhuphaukunciphisa ukukhutshwa kwe-nitrous oxide ngokujikelezisa inxalenye yombhobho we-injini ngeesilinda ze-injini.Oku kunezinye izinto ezingalunganga, eyona nto iyonakalisayo kukuvalelwa kwenkqubo yokuthatha.I-soot egqithisileyo ayiyi kunciphisa ukusebenza kwe-injini kuphela, kodwa ekugqibeleni ikhokelela ekugcinweni kwexabiso eliphezulu.
Ikhithi yokucima i-EGR isusa iIvalve ye-EGRkwaye ivumela injini ukuba isebenze ngaphandle kokujikeleza kombhobho.Ngamafutshane, kunciphisa ukukhutshwa kombhobho wesithuthi.Ibhekisela kwiteknoloji esetyenziselwa ukunciphisa ukukhutshwa kwe-nitrous oxide kwinkqubo yokukhupha.Oku kuphunyezwa ngokujikelezisa inxalenye yombhobho we-injini ngeesilinda ze-injini.Ekugqibeleni, isithuthi sakho sinokusebenza ngokungathi asizange sifakwe ivalve ye-EGR.
2.Ziziphi iiNzuzo zokucinywa kwe-EGR?
Uphuculo lwezoQoqosho lweFuel kunye noBomi obude beNjini
Ukucima i-EGRinokukunceda ukubuyisela umgangatho wamandla we-injini ye-diesel, enokubuyisela kwakhona ukusebenza kakuhle kwamafutha.Ngenxa yokuba ikhithi yokucima i-EGR iya kuphelisa igesi yokuphuma kwi-injini yemoto, iphinda iqalise ukucoceka.Ayiphuculi nje kuphela ukusebenza kakuhle kwenkqubo, kodwa ikwanciphisa nokuba nokwenzeka kokusilela kwe-DPF (i-diesel particulate filter).Ke ngoko, ngokubanzi, unokubona ukonyuka kwe-20% kuqoqosho lwepetroli ngale khithi yokuthengisa emva kokuthengisa.Ukongeza, ikhithi yokucima i-EGR inokuphucula ubomi benjini.
Inceda Ukugcina Imali
Ukucima i-EGR kunokukunceda ukuba wonge iindleko zokuyilungisa eziduru.Ukuba i-EGR yonakele, iindleko zokuyilungisa kunye nokutshintsha zinokuba phezulu kakhulu.Ukucima i-EGR kuphelisa ukuba nokwenzeka komonakalo onjalo, ngaloo ndlela ugcina imali yakho.
Nciphisa ubushushu benjini
Xa i-cooler okanye i-valve yenkqubo ye-EGR ivaliwe yi-soot, igesi yokukhupha iqala ukujikeleza rhoqo kwinkqubo.Oku kuvaleka kubangela ukuba ubushushu obujikeleze i-injini bunyuke.Xa udlula le ndawo yoyilo, amanqanaba asezantsi erhasi yokukhupha anokuveliswa, oko ke kucutha ubushushu be-injini yokupholisa ngexesha lokusebenza.
3.Ingaba akukho mthethweni ukucima i-EGR?
Ukucima i-EGRkuye kwafunyaniswa ukuba akukho mthethweni kuwo onke amazwe angama-50 aseUnited States.Oku kungenxa yokuba ukucima kwe-EGR kuya kubangela ungcoliseko.Zonke iitram kufuneka zihambelane nemigaqo yangoku yokukhupha injini eyenziwe ngurhulumente wobumbano.Kuya kufuneka uyazi ukuba ukuba uyasilela ukuhlangabezana nomgangatho kwaye ukuba ulwakhiwo olukhutshwayo luyatshintsha, isohlwayo sinokukubiza amawaka eedola.
Nangona kunjalo, ungasebenzisa isithuthi esinomsebenzi wokucima i-EGR kwindlela engekho endleleni, kodwa oku kusenemida yayo.Kulula ukuvala inkqubo ye-EGR ngomsizi ojikelezayo, kanye njengokuthintela ivalve kunye nepholile ekusebenzeni kwesiqhelo kwesithuthi.
Ngelizwi, ukucima i-EGR kukuguqulwa okuzisa inzuzo engenakunakwa.Nangona kunjalo, kwangaxeshanye, nayo ineengxaki zomthetho ezinokubakho.Ukuba uthatha isigqibo sokusebenzisa isithuthi sakho ekuqhubeni ngaphandle kwendlela, okusingqongileyo kuya kubangela iingxaki kwi-injini yakho.Ngakolunye uhlangothi, unokufumana ukusebenza okungcono, ubushushu obuphantsi kunye namandla aphezulu.Nangona kunjalo, kungcono ukuqwalasela ngononophelo iingenelo kunye nokungalunganga phambi kokuguqula ikhithi yokucima i-EGR.
