I-DENSO yinkokeli yehlabathi kwi-teknoloji ye-diesel kwaye kwi-1991 yayiyisixhobo sokuqala sokuqala (i-OE) umenzi we-ceramic glow plugs kunye noovulindlela benkqubo kaloliwe eqhelekileyo (CRS) ngowe-1995. ukudala izithuthi ezisabelayo, ezisebenzayo nezithembekileyo.
Enye yeempawu eziphambili ze-CRS, eziye zadlala indima enkulu ekunikezeni impumelelo ehambelana nayo, yinto yokuba isebenza ngepetroli phantsi koxinzelelo.Njengoko iteknoloji iye yavela kunye nokusebenza kwe-injini kuphuculwe, ngoko kuye kwanda uxinzelelo lwamafutha kwinkqubo, ukusuka kwi-megapascals ye-120 (MPa) okanye i-1,200 bar ekusungulweni kwenkqubo yesizukulwana sokuqala, ukuya kwi-250 MPa kwinkqubo yangoku yesizukulwana sesine.Ukubonisa ifuthe elimangalisayo oluveliswe lolu phuhliso lwemveliso, ukusetyenziswa kwepetroli okuthelekisayo kwehle ngama-50%, izinto ezikhutshwayo zehle nge-90% kunye namandla einjini anyuke nge-120%, ngexesha leminyaka eli-18 phakathi kwesizukulwana sokuqala nesesine iCRS.
Iimpompo zamafutha oxinzelelo oluphezulu
Ukuze usebenze ngempumelelo kuxinzelelo oluphezulu olunjalo, i-CRS ixhomekeke kwizinto ezintathu ezibalulekileyo: impompo yamafutha, ii-injection kunye ne-electronics, kwaye ngokwemvelo ezi ziphuhlisiwe ngesizukulwana ngasinye.Ke, iimpompo zamafutha zoqobo ze-HP2 ezisetyenziswa ikakhulu kwicandelo lemoto yabakhweli ngasekupheleni kweminyaka yoo-1990, ziye zadlula kwizinto ezininzi ukuze zibe ziinguqulelo zeHP5 ezisetyenziswa namhlanje, kwiminyaka engama-20 kamva.Ubukhulu becala buqhutywa ngumthamo we-injini, zifumaneka kwi-single (HP5S) okanye i-dual cylinder (HP5D) variants, kunye nomthamo wabo wokukhupha olawulwa yivalve yokulawula i-pre-stroke, eqinisekisa ukuba impompo igcina uxinzelelo oluphezulu, nokuba okanye hayi. injini iphantsi komthwalo.Ecaleni kwempompo ye-HP5 esetyenziselwa iimoto zabakhweli kunye nezithuthi zokuthengisa umthamo omncinci, yi-HP6 yeenjini ezintandathu ukuya kwezisibhozo zee-injini kunye ne-HP7 yezakhono ezingaphezulu koko.
Izitofu zamafutha
Nangona, kuzo zonke izizukulwana, umsebenzi we-fuel injector awuzange utshintshe, ubunzima benkqubo yokuhanjiswa kwepetroli luye lwaphuhliswa kakhulu, ngokukodwa xa kuziwa kwindlela yokusabalalisa kunye nokusabalalisa i-fuel droplets kwigumbi, ukwandisa ukusebenza kakuhle kokutsha.Nangona kunjalo, yindlela ezilawulwa ngayo eqhubeka ifumana utshintsho olukhulu.
Njengoko imigangatho yokukhupha izinto ezikhutshwayo kwihlabathi liphela iye yaqina ngakumbi, ii-injection zoomatshini zanikezela kwiinguqulelo ze-solenoid ezilawulwa yi-electromagnetic, zisebenza ngee-elektroniki eziphucukileyo ukuphucula ukusebenza kwazo kwaye ke kuncitshiswe ukukhutshwa.Nangona kunjalo, kanye njengoko i-CRS iqhubekile nokuvela, ngokunjalo ne-injector, ukuze kuphunyezwe imigangatho yamva nje yokukhupha, ulawulo lwabo kuye kwafuneka ukuba luchaneke ngakumbi kwaye imfuno yokuphendula kwi-microseconds iyafuneka.Oku kubangele ukuba ii-injection zePiezo zingene kungquzulwano.
Endaweni yokuxhomekeka kumandla ombane we-electromagnetic, ezi zitofu zineekristale ze-piezo, ezithi, xa zibonakaliswe kumbane, zandise, zibuyele kubungakanani bazo bokuqala njengoko ziphuma.Oku kwandiswa kunye nokunciphisa kwenzeka kwi-microseconds kwaye inkqubo inyanzelisa amafutha ukusuka kwi-injector ukuya kwigumbi.Ngenxa yokuba banokusebenza ngokukhawuleza, ii-injection ze-Piezo zinokukhupha iinaliti ezininzi nge-cylinder stroke kwaye i-solenoid isebenze inguqulelo, phantsi koxinzelelo oluphezulu lwepetroli, ephucula ukusebenza kakuhle kokutsha ngakumbi.
Electronics
Into yokugqibela lulawulo lwe-elektroniki lwenkqubo yokutofa, ehambisana nohlalutyo lwezinye iiparamitha ezininzi, ngokwesiko kulinganiswa ngokusetyenziswa kwenzwa yoxinzelelo ukubonisa uxinzelelo kwisondlo sikaloliwe wamafutha kwiyunithi yokulawula injini (ECU).Nangona kunjalo, ngaphandle kokuphuhlisa itekhnoloji, izinzwa zoxinzelelo lwepetroli zisenokusilela, zibangele iikhowudi zempazamo kwaye, kwiimeko ezigqithisileyo, ukuvalwa ngokupheleleyo komlilo.Ngenxa yoko, i-DENSO ibe nguvulindlela enye indlela echaneke ngakumbi elinganisa uxinzelelo kwinkqubo yokutofa amafutha ngokusebenzisa inzwa efakwe kwisitofu ngasinye.
Ngokusekwe kwinkqubo yolawulo evaliweyo, iTekhnoloji ye-DENSO ye-Intelligent-Accuracy Refinement Technology (i-ART) sisitofu esizifundelayo esifakelwe i-microprocessor yayo, eyenza ukuba ilungelelanise ngokuzimeleyo ubuninzi benaliti yamafutha kunye nexesha kumanqanaba abo afanelekileyo kunye nokunxibelelana oku. ulwazi kwi-ECU.Oku kwenza kube lula ukujonga ngokuqhubekayo kwaye ulungelelanise inaliti yamafutha ekutshani ngakunye kwisilinda kwaye kuthetha ukuba nayo iyazihlawulela kubomi bayo benkonzo.I-i-ART luphuhliso olwenziwa yi-DENSO kuphela kwisizukulwana sesine se-Piezo injectors, kodwa iphinde ikhethe iinguqulelo ezisebenzayo ze-solenoid zesizukulwana esifanayo.
Indibaniselwano yoxinzelelo oluphezulu lwenaliti kunye neteknoloji ye-i-ART yinkqubela phambili enceda ukwandisa ukusebenza kwe-injini kunye nokunciphisa ukusetyenziswa kwamandla, ukuvelisa indawo ezinzileyo kunye nokuqhuba inqanaba elilandelayo lokuvela kwedizili.
I-Aftermarket
Enye yempembelelo enkulu kwi-aftermarket yaseYurophu ezimeleyo kukuba, nangona izixhobo zokulungisa kunye nobuchule ziphantsi kophuhliso lwenethiwekhi yokulungisa egunyazisiweyo ye-DENSO, okwangoku akukho ndlela yokulungiswa okusebenzayo kwiimpompo zesizukulwana sesine okanye ii-injection.
Ngoko ke, nangona inkonzo yesizukulwana sesine kunye nokulungiswa kwe-CRS kunokwenziwa, kwaye kufuneka, kuqhutywe licandelo elizimeleyo, iimpompo zepetroli okanye ii-injection eziye zasilela azikwazi ukulungiswa okwangoku, ngoko kufuneka zitshintshwe kwiindawo ezintsha zokulinganisa umgangatho we-OE ezibonelelwa ngabavelisi abahloniphekileyo, abanjalo. njenge-DENSO.
