Injini ye-Mitsubishi 4n14
Okuqukethwe
Inguqulo ekhubazekile ekopishwe ezinjinini zikadizili zaseYurophu, efakwe elolini eliyiveni i-L200 eminyakeni emibili edlule. Lena injini enama-injection e-piezo kanye ne-geometry turbine eguquguqukayo.
Incazelo Ebucayi
Injini engu-4n14 ingudizili ethandwa abashayeli abaningi baseRussia ngenxa yokuqina kwezomnotho. Nokho, awekho amathemba abonwayo esikhungweni sikagesi esisha, njengoba injini ithambile futhi izwela uphethiloli omubi. Futhi yini okumele imangale - sonke isakhiwo salungiswa kuzindinganiso zanamuhla ze-Euro-5. Umphumela waba injini eyinkimbinkimbi, engabikezeli ukuthi izohlala ingalungiswanga kuze kufike ku-100th miles mark.
Namuhla sekuyisiko ukukhiqiza izinjini ezibukeka zicwebezela futhi zonga. Eqinisweni, ngemva kwesikhathi sewaranti, kunzima kakhulu futhi kuyabiza ukukulungisa noma ukuzisebenzisa. Hlobo luni lokwethembeka esikhuluma ngalo lapha?
Nalapha, ngenxa yemfashini entsha, i-8-speed automatic transmission isebenza ngokuhambisana nenjini. Cabanga ngakho, 8 isivinini - kungani eziningi kangaka? I-smacks of dispobility, uhlobo oluthile lwezimpahla zabathengi baseShayina. Ngokwezibalo, abaneminyaka eyikhulu bayivelakancane kakhulu phakathi kwama-multi-speed automatic transmissions, futhi lokhu akumangazi.
Kuvela ukuthi i-4n14 iyimoto engavamile, eyinkimbinkimbi, ebizayo futhi engathembeki? Yebo, izimoto ezifakwe ngayo zizolahlekelwa kakhulu inani ngemuva kokugcinwa kwewaranti ngayinye elandelayo. Futhi uphethiloli wethu we-diesel, isiRashiya, obulala izinjini eziqine kakhulu zaseJapane - 4d56, 4m40.

Izinkinga
Injini ye-4n14 yintsha, ngakho-ke ayikazuzi ukubuyekezwa okuningi. Kodwa-ke, sekungenzeka ukuthi ufinyelele iziphetho ezithile ngokutadisha izici zayo zokuklama.
- Ama-injection e-Piezo athathwa njengezinto ezintsha zobuchwepheshe eziqubuke ngokushesha emhlabeni wezinjini. Asebenza ngokushesha izikhathi ezi-4 kunejwayelekile kazibuthe kagesi, kodwa ahluleka ngokushesha nje.
Umjovo we-diesel piezo - I-turbine enejiyomethri eguquguqukayo imbozwe ngomsizi ngokushesha okukhulu, ama-jam ngesikhathi sokusebenza.
- I-valve ye-EGR - akuvamile ukuthi ifinyelele amakhilomitha ayizinkulungwane ezingu-50 zemoto. Ukuhlanza i-valve ngemva kwe-15 km eyizinkulungwane kunconywa ngumenzi.
- I-Maivek - uhlelo lwe-Mitsubishi oludumile lwezigaba ezilungisekayo lusebenza kahle kakhulu okwamanje, okwamanje. Ngemuva kwalokho, ukungenelela okufanelekile ngesikhathi kuyadingeka.
- I-Common Rail iwuhlelo olubizayo olunamabhomu alawulwa ngogesi. Eqinisweni, ikhulu leminyaka elisha, kodwa ngakolunye uhlangothi, i-injector evamile ibonakala ilula futhi inokwethenjelwa.
- I-timing chain evele ikhona enjinini entsha engu-4m41 ikubeke kwacaca ukuthi eminyakeni yakamuva isibhebhetheke kakhulu. Insiza yamakhilomitha ayizinkulungwane ezingama-70 wedrayivu yensimbi, uyabona, ayiqinile kakhulu! Futhi, injini kufanele isuswe lapho ishintshwa, ngakho kungani bengalifakanga ibhande ngokushesha.
- Isihlungi esiyizinhlayiya esihlanganiswe nama-catalyst ngandlela thize asicacile kakhulu, okusho ukuthi ngeke sihlale isikhathi eside.
Ama-injection e-Piezo
Kushiwo kahle futhi kunembile: okuhle kunjiniyela kubi kumkhandi wezikhiye. Lokhu kumayelana nama-injection e-piezo, ukulungiswa kwawo okwesabisayo kwangempela kwabasebenzi bokukhanda izimoto. Namuhla, izijovo ze-piezo ziya ngokuya zisetshenziswa ezinhlelweni zikaloliwe ezivamile ezinjinini zikadizili. Bagqugquzelwa abaklami abasebenzise amathuluzi obuchwepheshe obuphezulu bokushuna kahle injini evuthayo yangaphakathi. Kodwa omakhenika nabanikazi bezimoto bagcina sebenenqwaba yezinkinga zezimali nezobuchwepheshe okunzima ukuzixazulula.
Esikhundleni sikazibuthe kagesi onomgogodla ohambayo, i-piezo injector inikezwe isici esikhethekile ngendlela yekholomu yesikwele. Ngamanye amazwi, lena iqoqo lamapuleti e-ceramic ahlanganiswe phezulu komunye nomunye futhi athengiswa, lapho, ngaphansi kwethonya lamanje, umphumela we-piezoelectric kwenzeka. Idizayini ye-piezo injector iyindawo yonke, iyakwazi ukushintsha ubude bayo ngesikhathi esifushane, ngaleyo ndlela isebenze ku-valve yokulawula. Uma kuqhathaniswa nomjovo ovamile, lokhu ukwanda kwejubane lokuphendula ngo-0,4 ms, amandla amakhulu ku-valve kanye nokunemba okuphezulu kokunqamula ukunikezwa kukaphethiloli. Ngamafuphi, ngokwengqikithi eyodwa kuphela ama-pluses.
Manje ngobubi. Ngokombono wenkonzo, inkinga eyinhloko yama-piezo injection yinkimbinkimbi ephakeme yokulungisa kwabo. Ngaphezu kwalokho, lezi izakhi ezibucayi kakhulu ezisabela ekuwohlokeni okuncane kwekhwalithi kaphethiloli wedizili. Ukuthululela njalo uphethiloli omuhle ngezinga eliphakeme lokuhlanzwa eziteshini zikaphethiloli eRussia akunangqondo, ngakho-ke, ngemva kwamakhilomitha ayizinkulungwane ezimbalwa, izimoto ezinohlelo olunjalo ziyalungiswa.
Yonke inketho yokushintsha nayo iyacatshangelwa. Kodwa lapha, futhi, akukho lutho oluhle kumaRussia - ama-injection amasha e-piezo ayabiza kakhulu. Isixhumanisi esisengozini kakhulu ohlelweni lwe-piezo injector yi-valve yokulawula, ukwehluleka okusongela ukulimaza wonke umjovo.
Oguquguqukayo wejometri ephendulwa
Umehluko phakathi kwe-turbine evamile kanye nokwehlukile okunejiyomethri eguquguqukayo ukuthi, uma kuqhathaniswa neyakudala, isigaba sokungena kwamasondo siyashintshwa lapha. Lokhu kwenziwa ngenjongo yodwa yokwandisa amandla e-turbine yomthwalo onikeziwe.
Injini ene-turbine enjalo inomfutho ophakeme kakhulu. I-Supercharging ilawulwa idrayivu, isilawuli se-vacuum kanye ne-stepper motor.
Empeleni, i-geometry turbine eguquguqukayo ibhekwa njengenye yezinhlelo ezihamba phambili zokushaja ze-turbo kusezingeni. Ingcono kune-twinscroll, i-turbo ne-turbine eyodwa, icishe ilingane ne-turbine kagesi kanye ne-twinscroll eguquguqukayo. Kodwa, futhi, izinga likaphethiloli we-diesel liza kuqala - uphethiloli ompofu uyonakalisa ngokushesha lolu hlobo lwe-turbine.
Isihlungi se-Particulate
Isici sifakwe ezinjinini zikadizili isikhathi eside. Yenzelwe ukuhlanza umkhathi wensimu eyeqile, egcwele uphethiloli wedizili. Ukufaka isihlungi se-particulate ku-Mitsubishi 4n14 kufana nokuhlonipha izazi zemvelo, ngoba yibona abaqhamuke nale ndlela.
Eqinisweni, isihlungi sezinhlayiya sithatha indawo ye-catalyst noma ukungezwa kwayo. Iyunithi ehlukile efakwa ngemuva kwe-catalyst noma ihlanganiswe nayo - njengasenjini ye-4n14 ne-Volkswagen.
Ngokusobala, kusuka kuphethiloli omubi, isihlungi sezinhlayiya sizovaleka ngokushesha, okuzodala umgoqo obonakalayo wamagesi futhi kunciphise amandla enjini.
Ividiyo: Ukubuyekezwa kweDelica ngenjini yedizili
Isiphetho mayelana nenjini ye-4n14: entsha, ethuthuke kakhulu kwezobuchwepheshe, ihlangabezana nezindinganiso ze-Euro-5. Kodwa kunzima ukuyibiza ngokuthi ithembekile, ilondolozeka futhi ishibhile.
