Injini yeRenault 2,0 dCi - M9R - Isihlalo semoto

Ama-turbines avame ukwehluleka, izinkinga ezivamile ohlelweni lomjovo, ukuhluleka kwesikhathi se-valve, amavalvu egesi ashisiwe aphinde ajikelezisa igesi ... Lapho abakwaRenault beqaphela ukuthi izinjini zabo zikadizili eziyi-1,9 dCi (F9Q) zazingelona inadi langempela, futhi ukwehluleka njalo konakalisa igama lenjini. automaker, wanquma ukuthuthukisa lokho ngokuyinhloko injini entsha, enokwethenjelwa futhi eqinile. I-Workshops iRenault, ngokubambisana nabakwaNissan, yahlanganyela, futhi uphiko olusha, oluthembisa ukuqina, akuzange kube yisikhathi eside ukufika. Ingabe waphumelela ngempela? Kuze kube manje, isipiliyoni sibonise ukuthi kunjalo.

Kwakungu-2006 kwathi injini engu-2,0 dCi (M9R) yangena emakethe. Isizukulwane sesibili iRenault Megane neLaguna kube yiso lesi sihlalo esisha esizinze. Kuqale kwaba nohlobo lwe-110 kW ongakhetha kulo, ngokuhamba kwesikhathi kwengezwa ama-96 kW, ama-127 kW kanti inguqulo yakamuva ime kuma-131 kW. Iyunithi yamandla ka-4 kW ihambisana ne-Euro 4 ejwayelekile, kanti ezinye izindlela ezinamandla kakhulu bezingalingani nezinga le-Euro XNUMX ngaphandle kokufakwa kwesihlungi se-particulate. Kodwa-ke, le "pendant" yezemvelo ngokuqinisekile ngeke ivimbele abathandi bokushayela okusheshayo nokushesha ekuthengeni, njengoba kufakazelwa ukuthengiswa kwenguqulo enomoya we-Megane RS.

injini

I-robust cast iron monoblock ene-84 mm bore kanye ne-90 mm stroke iqinisekisa ukuthembeka nokuqina kwenjini egumbini lomlilo. Ibhulokhi yensimbi ihlukaniswe ncamashi eceleni kwe-crankshaft, ebekwe ezindaweni ezishelelayo ezindaweni ezinhlanu. Kukhona imbobo encane engxenyeni engenhla yesibambiso esiyinhloko, esiza ukukhipha kangcono amagesi asebenza enjini ngenkathi isebenza. Vele, amakamelo amakhulu omlilo kufanele futhi apholiswe kahle ngoba ayingxenye yenjini ecindezeleke kakhulu. Igumbi lomlilo lipholile ngomgudu wokugcoba ohamba uzungeze wonke umzungezo we-piston, lapho iphampu lifaka khona uwoyela ngombhobho.

Ayikho into ekhethekile eyasetshenziswa kubhavu kawoyela. Kwakungenasidingo sokunamathisela noma yini kukho, ngakho-ke akuyona iphivothi noma iphuzu okusetshenzwa kulengwa kulo. Ipani likawoyela lakudala, elenziwe ngothayela wensimbi, lakha phansi kwayo yonke injini futhi mhlawumbe alidingi kuphawulwa. Kufakazelwe, kusebenza kahle, futhi kushibhile ukukhiqiza. Kuphela lapho umthwalo we-aluminium alloy crankcase okhanyayo udingeka. Okokuqala, yiqiniso, yenza umsebenzi wokuqinisa umzimba uqobo, futhi iphinde isebenze ekuvimbeleni injini injini. Kodwa-ke, ifreyimu uqobo isebenza njengemiphini emibili yokulinganisa ephikisanayo eqhutshwa ngamagiya ngqo kusuka kulayini. Lezi shaft zenzelwe ukuqeda noma yikuphi ukudlidliza okungafuneki kusuka enjinini.

I-1,9 dCi izinjini imvamisa ibinenkinga yokungagcobiswa kahle ngenxa yokuthi isisefo sikawoyela sibe sincane kakhulu enjinini enkulu kangaka. I-roller encane, eyanele isithuthuthu, akwanele ukugcoba injini enzima kangaka, ngisho nenkathi yesevisi enwetshiwe (umkhiqizi ufuna i-30 km). Kuyinto engacabangeki. "Isihlungi" sincane, sivalwe ngokushesha ngamalahle futhi silahlekelwa ikhono laso lokuhlunga, ngakho-ke ukuvuthwa kwaso kuyancipha, okugcine kuthinta impilo yesevisi - ukuguga nokudabula kwezihlungi eziningi ezilahlwayo.

Ngakho-ke abakwaRenault baqhamuka nobusha abanye abasebenzisi bezimoto abebesebenzisa isikhathi eside. Isihlungi esincane esingasebenzi sithathelwe indawo isihlungi esisha sha esikhudlwana. Isihlungi esidala sensimbi sishintshiwe ngokuphelele. Isiphathi sesihlungi se-alloy esikhanyayo manje sesiphuma esakhiweni se-cylinder, lapho kufakwa khona kuphela okufakwe ephepheni, okuhlala kufakwa okusha kwesinye ekushintsheni kukawoyela okulandelayo. Uhlelo olufanayo nathi, ngokwesibonelo, oluvela ezinjinini ezivela kwa-VW. Lesi yisixazululo esihlanzekile neshibhile kubo bobabili abakhiqizi bezimoto futhi, ekugcineni, amagaraji kanye nabathengi. I-cooler kawoyela, okubizwa ngokuthi yi-oil-water heat exchanger, nayo ifakwe kumnikazi wesihlungi samafutha.

Isehlukaniso

Ibhande lesikhathi elijwayelekile nalo selithathelwe indawo ngebhande leketing timing esimweni senjini ye-M9R. Lolu hlelo alugcini ngokuqina kakhulu futhi luhlala isikhathi eside, kepha futhi aludingi ukunakekelwa ngakho-ke luthembekile ngokwengeziwe. Uchungechunge lwesikhathi se-roller irowu elilodwa lufakwa nge-hydraulic ngu-roller wokubacindezela ngezinduku ezimbili zokugoqa, njengoba sazi kakade, ngokwesibonelo, ukusatshalaliswa kwe-1,2 HTP. I-tensioner iqhutshwa yi-camshaft etholakala ohlangothini lwe-exhaust, njengoba le njini ingenayo i-camshaft ehlukile yokukhipha futhi ihlukaniselwe ama-valve wokudla, kepha zombili izinhlobo zama-valve ziqhutshwa ngokushintshana nge-shaft ngayinye. Njengoba injini inama-valve angu-16, i-valve ngayinye ilawula ama-valve amane okukhipha namane okukhipha i-converter ngayinye. Amaphayiphu alungiswa ngogesi esebenzisa izingalo zerock ezisebenza yodwa ukuqinisekisa ukusebenza kwesikhathi eside okungenazinkinga, ngokuya ngezikhawu zokulungisa ezivamile. Lapha futhi, umthetho uyasebenza: izinga likaphethiloli liyanda, impilo yensizakalo yayo iba yinde. Ama-camshafts aqhutshwa ukuhanjiswa kokungqubuzana, i.e. igiya elinomkhawulo wokubuyela emuva. Sesivele sazi konke kusuka kumamodeli wangaphambilini wezimoto ezincintisanayo, kodwa into eyodwa ihluke kakhulu. Ingxubevange ye-aluminium ekhanda lesilinda ayisalutho olukhethekile. Kulezi zinsuku, cishe wonke umuntu uyayisebenzisa, kepha uma kwenzeka kudilika udizili osuka empomfweni ophakeme, udizili ubhajwe ethangini abese efaka ipayipi lokukhipha amanzi. Elinye ikhanda lesilinda liqukethe izingxenye ezimbili. Ingxenye yayo engenhla yakhiwa ikhava ye-valve, umsebenzi wayo ukuqinisekisa ukuqina okuphelele kwesikhala sokuthambisa sama-valve futhi, ngasikhathi sinye, iphuzu labo eliyisithenjwa njenge-plain bearing, ngaleyo ndlela linqume ukudlala kwabo. Okuthiwa okuhlukanisa uwoyela kusengxenyeni engenhla yesembozo se-valve. Uwoyela ochithiwe uqoqwa kulesi sihlukanisi, lapho uqondiswa khona kusihlukanisi (pre-separators), lapho ungena khona kusihlukanisi esikhulu, esine-valve yokulawula eyakhelwe ngaphakathi ebhekele konke ukwahlukaniswa kukawoyela. inqubo. Lapho izinga eliphakeme lamafutha ahlukanisiwe lifinyelelwa, uwoyela umane ukhishwe ubuyele esifundeni esikhulu ngamapayipi amabili. Amashubhu acwiliswa kumasiphoni okudonsa. Lesi sikhala sonke sigcwele uwoyela ukuvimbela ukuqongelelwa kwegesi okungafuneki esakhiweni se-cylinder.

I-Turbocharger

Njenganoma iyiphi injini yesimanje kadizili, i-2,0 dCi (M9R) ine-turbocharged. I-Renault yenze izinguquko nalapha, futhi ezibanzi impela. I-turbocharger entsha manje isipholile ngamanzi (kuze kube manje sibone le sistimu kuphela enezinjini zikaphethiloli) isuka ngqo kumjikelezo wamanzi webhulokhi yokupholisa injini, okuqinisekisa izinga lokushisa elizinzile kulo lonke uhambo. Ngemva kokushayela isikhathi eside emgwaqeni omkhulu, akusadingeki ukushiya imoto idlile isikhashana (cishe imizuzu engu-1-2) bese ulinda i-turbocharger eshisayo ukuthi iphole kancane. Lokhu kususa ubungozi bokuthwala umonakalo onganqwabelana kumle lapho i-turbocharger ishisa futhi ingapholisiwe. I-automaker ithathe indawo ye-turbo eqinile futhi ebolayo ezinjinini zangaphambilini zikadizili eziyi-1,9 dCi yafaka i-turbo enamandla kakhulu. "Ama-lightweights" e-turbocharger entsha ama-vanes aguquguqukayo alawulwa yiyunithi yokulawula, ekwazi ukulawula ukucindezela kokugcwalisa kahle kakhulu futhi cishe kunoma yiliphi ibanga lesivinini.

Ukujova

Uhlelo olujwayelekile lokujova ujantshi, lapho iRenault isebenzisa i-EDC 16 CP33 yesizukulwane sakamuva esivela eBosch, nayo ilungisiwe. Iphampu entsha yokuphakela ipompo entsha ye-CP3 itholakele ethangini likaphethiloli. Uhlelo luhlale lucishe lufane, kufakwa kuphela iphampu entsha kumgomo wokumunca, hhayi umjovo ophakeme kakhulu, njengoba kwakunjalo ohlelweni oludala. Iyunithi yokulawulwa kokuhamba kukaphethiloli ikhombisa ukuthi umjovo kufanele uvulwe ngezinga elingakanani nokuthi i-injector kufanele ivulwe kangakanani nokuthi ngakanani uphethiloli okufanele unikezwe kusuka ethangini yimpompo yokuphakelayo. Ngaphezu kwalokho, umjovo uhlinzekwa ngokulawula ingcindezi kusitimela somjovo. Ngokushesha ngemuva kokuqala, ngeke kube khona umthamo ophelele wokugcwalisa emgqeni, kodwa kube ingxenye eyodwa kuphela, ukuze injini ikhumbule ngokushesha ngemuva kokuqala nokufudumala kancane kancane. Ukulawulwa kwengcindezi yesitimela kuyasetshenziswa futhi lapho ipediyali ye-accelerator ikhishwa ngokungazelelwe ngenkathi ushayela, ngakho-ke akunamphumela wokucindezelwa ngokweqile. Ukuthi nje uma udedela i-pedal, imoto ayijezi. Ukubuyiselwa kwamagesi okukhipha kuqinisekiswa yi-valve yokukhipha igesi epholile, elawulwa yimoto kagesi hhayi nge-pneumatic (vacuum). Ngakho-ke, i-valve ye-EGR ingashintsha isikhundla sayo noma ngabe isimo asiyidingi. Lo mnyakazo uqinisekisa ukuthi i-valve ayivalwanga yimisi yokukhipha kanye ne-oyile yokuthambisa uwoyela.

Ama-injectors we-solenoid ahlelwe kabusha futhi kwafakwa ama-piezoelectric amasha, athembeke kakhulu kunama-solenoid injectors, angafinyelela umfutho ophakeme kakhulu wokuqina, owagcina ufinyelela ku-1600 bar, ngemuva kwalokho uphethiloli uze ube mncane kakhulu. kufuthwe ekamelweni lomlilo. Kokunye ukushaywa kwe-piston, i-injector isebenzisa i-petroli ngokushesha kahlanu. Umkhiqizi uthe lokhu kungenxa yemizamo yokwehlisa umsindo wangaphandle wayo yonke iyunithi kadizili.

AbakwaRenault bahlale belwela ukukhiqiza izinhlobo ezibizwa ngama-eco-friendly. Ngakho-ke, ekukhiqizeni nasekuthuthukiseni izimoto ezintsha, wayehlala ecabanga ngemvelo nokongiwa kwemithombo engavuseleleki. Isihlungi se-diesel particulate filter esivuselelwa njalo njalo ngama-500-1000 km, kuya ngokuvalwa kwesihlungi, futhi sinakekela ukwehlisa ukukhishwa. Uma iyunithi yokulawula injini ithola ukuthi ingcindezi engenhla nengezansi kwesihlungi se-particulate ayifani, inqubo yomlilo iqala ngokushesha, ehlala cishe imizuzu eyi-15, kuya ngezinga lokuvalwa kwesihlungi. Phakathi nale nqubo, uphethiloli ufakwa kusihlungi nge-piezoelectric injector, okwenza izinga lokushisa lifike cishe ku-600 ° C. Uma uhamba njalo edolobheni, sincoma ukuthi ugijimise imoto yakho emgwaqeni omkhulu ngesivinini esiphezulu isikhathi nesikhathi okungenani imizuzu engama-20. Injini izohlomula kuphela ngemuva kwesikhathi eside uzungeza idolobha.

Okuhlangenwe nakho Okungokoqobo: Isikhathi sibonisile ukuthi nakuba le njini inesakhiwo sensimbi esimangelengele kanye neketango elingenakulungiswa elishiwo ngenhla kanye ne-turbocharger epholiswe ngamanzi, ibingethembekile. Kwesinye isikhathi kungamangaza ukuthi uphawu oluqhekekile ngaphansi kwekhanda le-cylinder, kuphinde kwaba khona ukuhluleka kwepompo likawoyela futhi kube nezigameko ezaziwayo zokuquleka kwe-crankshaft lapho ama-bearings enduku exhunywayo enziwa usayizi omncane (alungiswa ngo-2010) kodwa ngokuvamile anethemba elingaphezu kwamandla. uwoyela ukushintsha izikhawu. - Amakhilomitha ayizinkulungwane ezingu-30, okunconywa ukuthi ancishiswe abe max. 15 km. 

Ukudluliswa kokutheleleka

Izinjini eziwuchungechunge ze-2,0 dCi (M9R) zihlanganiswe no-gearbox okhanyayo we-light light alloy ukudiliva ku-360 Nm we-torque. Amagiya ayisithupha nemiphini emithathu kusikisela ukuthi lo mshini uqobo lwawo uvela kunguqulo yangaphambilini, ebizwa nge-PK6 enamakhodi.

Imodeli yemoto esindayo isebenzisa lokhu kudlulisa okudala, kwaba nephutha ngokwengeziwe. Ukulungiswa kwe-shaft Transmission shaft, okuvame ukuthi kube yisikhathi sokufakwa kwamagiya okukhulunywe ngaso kulezi zinkundla, kungaba yinto yesikhathi esedlule futhi singakholelwa nje ngokuqinile ukuthi ukudluliswa okusha kweRenault Workshop Retrofit (PK4) kuzisuse ngokuphelele lezi zinto ezingenhla.
