I-Motor 1,0 MPI 12V (EA211 – CHYA, CHYB, CPGA)

Ukunciphisa kuyabusa emhlabeni wezimoto, futhi umkhuba wokunciphisa ukusetshenziswa kwezimoto ucindezela abakhiqizi bezimoto ukuthi bathuthukise futhi kamuva bakhiqize amayunithi enjini angavumelani kakhulu nemvelo futhi angawongi kakhulu ukuze akhiqize. Enye yazo iphinde ibe yi-1,0-cylinder 3 MPI, efakwe ezimotweni ezincane (VW Up!, Škoda CitiGo, Seat Mii), kanye naseFabia No. 1,2, lapho kuyinjini eyisisekelo. Ngakho-ke, umngane omdala ongu-XNUMX HTP uhamba kancane kodwa ngokuqinisekile uyahamba ayokuphumula okumfanele kakhulu.

Ngomoya wokunciphisa, wonke umqondo we-1,0 MPI motor unit (EA211) uyenziwa. Uma kuqhathaniswa ne-1,2 HTP, ilula, ilula futhi iyahlangana, kepha ngasikhathi sinye ayinabo ubuchwepheshe besimanje bwanamuhla. Zisetshenziswa kuphela lapho zidingeka khona ngempela ngokubuka kokusebenza. Izingxenye eziningi ezingadingekile zisuswe ngokuphelele noma zafakwa esikhundleni senketho elula nethembeke kakhulu, ngoba injini kufanele imelane nokucindezela kwethrafikhi yedolobha, okungukuthi, ukuqala kaningi namabhuleki noma ukuqala kaningana ngosuku ebusika noma ehlobo. Ngesikhathi sokukhiqiza, kunakwe kakhulu izindleko eziphansi kakhulu zokukhiqiza, kanye nokugcinwa kwe-injini okulula futhi okungabizi kakhulu kuyo yonke impilo yemoto.

Umehluko omkhulu phakathi kwe-1,2 HTP ne-1,0 MPI

Ku-1,2 HTP ama-piston anesibalo esingu-76,5 nobude obude obude obungu-86,9 mm, kuyilapho ku-1,0 MPI ama-piston enesithukuthezi kanye nohlangothi olungu-74,5 x 76,4 mm kuphela. Endabeni ye-1,2 HTP, ama-piston ngaleyo ndlela afinyelela isivinini esiphakeme kakhulu, okusho ukuthi ukudlidliza nokuphakama okukhulu kakhulu. Ngakho-ke, ukuze kuqedwe ukudlidlizela nokudlidliza okungafuneki, i-crankshaft iqukethe izinsimbi ezinkulu zokulwa ezisethilini ngalinye le-crankshaft. Umphini webalancer nawo usiza ukunciphisa ukudlidlizela nokudlidlizela.

Ku-1,0 MPI, ama-piston anesivinini esiphansi, ngakho-ke kusetshenziswa izinsimbi ezilula, ezitholakala ngokungeziwe kuphela kuzikhonkwane zokugcina ze-crankshaft. Ngaphezu kwalokho, isisindo se-counterweight sitholakala kude ne-crankshaft axis of rotation, ukuze i-inertia efanayo ifinyelelwe ngomshini we-crank crank. Lezi zakhiwo zenze ukuthi kube lula ukushiya shaft yokulinganisa. Lokhu kubonisa ukwehla okuphawulekayo kokulahleka kwemihuzuko, okuyisinyathelo esibalulekile esimweni senjini engamasilinda amathathu ukufeza ukusebenza kahle kwemishini ngakho-ke ukusetshenziswa okuphansi kuqhathaniswa nezinjini ezine zamasilinda ezinosayizi ofanayo. Vele, ukungalingani (ukudlidliza i-oda lokuqala) akunakususwa ngokuphelele kumgomo wokuklanywa kwamasilinda amathathu. Ukwehliswa okuhamba phambili kwalokhu kudlidlizela nokudlidlizela kunikezwa ngokuqina okuyinkimbinkimbi kwenjini emzimbeni wemoto.

Ngalezi zici, injini ye-1,0 MPI inokusebenza okungcono kakhulu, umsindo ophansi nokudayela okulula uma kuqhathaniswa ne-1,2 HTP. Injini entsha inamapayipi wokupholisa opholile, ngakho-ke asikho isidingo sokuvikela isiguquli sokuguqula ngokunothisa ingxube ngesikhathi sokusebenza okunzima kakhulu (ngokwesibonelo, lapho ushayela emgwaqeni). Ngamanye amagama, ukushayela ku-130 evumelekile akusasho ukuthi kuzongena kusetshenziswa amanani we-9-10 litres, kepha kumayelana namalitha ayi-7. Esikhundleni seketanga lesikhathi, umshini wesikhathi ushayela ibhande elinamazinyo eliguquguqukayo elingabhekana kangcono nokudlidlizela komoya okwakhiwe ngamasilinda amathathu.

injini

Ubulula bungaphezu kwakho konke. I-injini block ngokwayo yenziwe kulo moya. Injini entsha engu-999 cc enamasilinda amathathu yenziwe nge-aluminiyamu eqinile, engasindi ukuze kwehliswe isisindo sisonke seyunithi. Amasilinda enjini afakwe izinsimbi ezikhethekile ezimpunga futhi aphonswa ngqo kubhulokhi ye-aluminium. Umkhiqizi wenze isiqiniseko sokuthi isilinda siqinile futhi singashisa ngisho nophethiloli wekhwalithi ephansi. Izimbobo zokuphuma ezihlukene noma izimbobo zikawoyela sezivele zibunjiwe ebhulokhini, okuqeda isidingo sokunye ukudonsa njengoba kuvamile kwezinye izinjini. Ibhulokhi ipholiswa ukupholisa kwamanzi emvelo, okubizwa ngokuthi i-Open Deck, lapho ingxenye engaphezulu yamasilinda ivuleleke ngokuphelele ekugelezeni kokupholisa, futhi ngaleyo ndlela isikhala esizungeze amasilinda sipholile ngokuphumelelayo. Okuwukuphela kokwahlukanisa phakathi kwalesi sikhala nekhanda wuphawu olungaphansi kwekhanda.

Zonke izibopho zekhebula, amapulasitiki ahlukahlukene noma amapayipi afakwa abese enamathiselwa ngqo kubhlokhi yenjini ukuthola okokusebenza okwengeziwe nokonga isisindo. Phansi kwebhokisi lesilinda kufakwe indlu ye-aluminium alloy crankshaft kanye nepani lamafutha lensimbi elilula. Amabheringi amane asobala afakwe i-crankshaft yensimbi engasindi okuthi, ngenxa yenjini eyenziwe kabusha, ayidingi ishafu yokulinganisa ukuqeda ukunyakaza. Idizayini ecatshangwe kahle enamabhulokhi akhethekile athule aqinisekisa ukuthi ukudlidliza okungafuneki nokudlidliza okusuka enjinini kuya emzimbeni kuyakhishwa.

Ikhanda lesilinda nalo lenziwe nge-alloy elula, futhi ngesikhathi sokukhiqizwa kwayo, kwathathwa ukunakekelwa ukuze kuqinisekiswe ukuthi injini ifudumeza izinga lokushisa ngokushesha ngangokunokwenzeka nangesikhathi esifushane kakhulu. Abaqambi banqume ukuhlanganisa ingxenye yepayipi lokukhipha ngqo esifundeni sokupholisa uketshezi. Ngakho-ke, ezimotweni zedolobha, iyunithi lonke lishisa kakhulu ngokushisa okusebenzayo. Lokhu kunciphisa ukufinyela komphunga ekhavini yekhanda lesilinda, ukufinyela kukaphethiloli ezindongeni zesilinda, futhi kunciphisa nokugqokwa kwezinjini jikelele nokusetshenziswa kukaphethiloli.

Izehlukaniso

I-camshaft ayinakuthathelwa indawo enye entsha uma ilimele noma igqoke ngokweqile. Iyacindezelwa ijwabu leso le-valve kusetshenziswa indlela ekhethekile. Isivalo sishisa size sifike ekushiseni okuphezulu futhi umongo ube yiqhwa ngaphansi kweqhwa. Umphini opholile ngale ndlela ufakwa emigodini ethwele isembozo esivuthayo. Lapho amazinga okushisa wezinto ezilinganayo elingana, kwakhiwa ukuxhumana okuqinile naphakade ku-fulcrum. Lokhu kwakha iyunithi yokwakha enzima kakhulu kepha engasindi.

Ama-camshafts amabili aqhuba ama-valve ayi-12 esewonke (ama-valve amabili wokudla kanye nama-exhaust amabili nge-cylinder), ngenzuzo yokuthi injini igcine ama-valve tappets. Lesi sixazululo sibuye sikulungele kakhulu ukushisa amanye amandla okubasa (i-LPG / CNG). Isikhathi samaphayiphu okudla siyashintshwa ukuze injini isebenzise kangcono ibanga lejubane elibanzi. Uhlobo lwenjini olunamandla angama-55 kW lunejubane elingu-2000 6000 kuye ku-XNUMX ngomzuzu, okwandisa ukushesha kwalo.

Ibhande lesikhathi lifihlwe ngaphansi kwesembozo sepulasitiki ngakwesobunxele (manje "esejwayelekile") senjini. Kuyathakazelisa ukuthi ikhava yothuli lwayo nokwakheka kwesikhathi okulula kuqinisekisa ukuthi asikho isidingo sokushintsha ibhande kukho konke ukuphila kwenjini. Ukwelashwa okukhethekile kweTefon ngaphakathi kwebhande lesikhathi kuqinisekisa ukumelana okuphansi kokungqubuzana.

Uhlelo lokujova kanye nokuphindaphinda kokudla

Okokhelekayo kufakwa egumbini lomlilo ngabajovo abathathu ngokucindezela ibha engu-3 kuphela. Ngakho-ke, iphampu kaphethiloli isiyonke ayicindezelekile. Lokhu kuncishiswa kwengcindezi yomjovo kunomphumela omuhle empilweni yesevisi yepompo uqobo. Leli xabiso litholwe ngokusetshenziswa kokuphindaphindeka kokutholwa okungu-550 mm ubude, okuqukethe izigaba ezine, nokufakwa kwekhwalithi ephezulu kwezinhlobonhlobo kanye nojantshi kaphethiloli kusuka ekushiseni okukhishwa yenjini uqobo. Uphethiloli awushisi ngokweqile, futhi "ukuphuphuma amagwebu" kukaphethiloli kuyancishiswa, ngaleyo ndlela kuqedwe amabhamuza ohlelweni lokujova.

Ukuphola

Ukupholisa injini kunikezwa ngendlela engavamile ngokuphelele. Iphampu yamanzi engasindi ye-aluminium alloy itholakala ohlangothini olungakwesokudla lwenjini (ohlangothini lokuhambisa). Iphampu lamanzi liqukethe nemodyuli ye-thermostat uqobo, ngakho-ke inani nobude bamapayipi okupholisa amanzi angasasebenzi agcinwe ngokuphelele. Iphampu lamanzi liqhutshwa ibhande lalo, ngenxa yokuhleleka kwenjini. Yonke le set (ipompo lamanzi + i-thermostat) ifakwa ngqo esikhungweni senjini futhi ngaleyo ndlela yakha iyunithi elilodwa esifundeni sokupholisa.

44 noma 55 kW?

Injini eyisilinda emithathu itholakala ngezilinganiso ezimbili zamandla: 44 kW (60 hp) ku-5500 rpm no-55 kW (75 hp) ngo-6200 rpm, womabili afinyelela ku-95 Nm ku-3000 rpm. -4300 ngomzuzu. Kodwa-ke, kwezinye izindlela zokushayela, izinguqulo ezimbili ziyehluka kakhulu kunokusebenza okusikisela ekuboneni kokuqala.

Empeleni, umehluko wethrafikhi yedolobha phakathi kwalezi zinguqulo ezimbili mncane, njengoba kufakazelwa ukubheka amandla namagrafu we-torque wazo zombili izinjini. Umehluko omncane oshiwo ungenxa yokuphelezelwa okude kancane kwenguqulo enamandla. Umehluko omkhulu kakhulu uyenzeka lapho ushayela ngokushesha. Inguqulo ebuthaka iphenduka ku-130 km/h cishe ku-3700 rpm, inguqulo enamandla ngo-3900 rpm (isebenza ku-Citigo). Emazingeni abuthakathaka angaphezu kuka-4000 rpm, ukwehla okubaluleke kakhulu kwetorque kuyaqala futhi ijika lamandla alinyuki kakhulu. Endabeni yenguqulo enamandla, ijika lamandla likhuphuka ngokuphawulekayo futhi limemezele ukusabalala kwalo libe ngu-6200 rpm. Ngokufanayo, inani letorque liqala ukwehla kakhulu.

Imininingwane engenhla ikhombisa ukuthi inguqulo ebuthakathaka ilungele kakhulu ukushayela edolobheni nasendaweni ezungezile, lapho isivinini singeqi cishe ku-115 km / h. injini. Uma ushayela ngale ndlela, inguqulo ebuthakathaka nayo ibiza kancane ngoba inamagiya amade.

Ngakolunye uhlangothi, inguqulo enamandla amakhulu ingcono ekuphatheni ukuhamba kwezimoto ezisheshayo nokusheshisa ngejubane eliphakeme, kungaba ngegiya lesihlanu noma ngokushintsha phansi bese uguqula injini. Yize kune-dynamics engcono, noma inguqulo enamandla kakhulu ayifanele ukushayela imigwaqo ejwayelekile futhi enwetshiwe, lesi siyalo siphathwa kangcono kakhulu yizinjini ezinkulu / ezinamandla kakhulu ezinamagiya ayisithupha noma ngaphezulu.
