Renault H4D, H4Dt izinjini
Okuqukethwe
Abakhiqizi bezinjini zaseFrance bayaqhubeka nokuthuthuka ekuthuthukisweni kwamayunithi wamandla wevolumu encane. Injini abayidalile isivele yaba injini eyisisekelo yezinhlobo eziningi zezimoto zesimanje.
Incazelo
Ngo-2018, embukisweni wezimoto waseTokyo (Japan) kwethulwa iyunithi entsha yamandla ehlanganiswe ngonjiniyela baseFrance nabaseJapan iRenault-Nissan H4Dt.
Isisekelo somklamo kwakuyinjini ye-H4D efunwa ngokwemvelo, eyakhiwa ngo-2014.
I-H4Dt isakhiqizwa endlunkulu yenkampani e-Yokohama, e-Japan (njengoba iyisisekelo sayo, i-H4D).
I-H4Dt ingu-1,0 litre three-cylinder turbocharged petrol ekhiqiza amandla angu-100 hp. s ku-torque engu-160 Nm.
Kufakwe ezimotweni zakwaRenault:
- I-Clio V (2019-н/вр);
- I-Captured II (2020-XNUMX)
OkweDacia Duster II kusukela ngo-2019 kuze kube manje, nangaphansi kwekhodi HR10DET yeNissan Micra 14 kanye ne-Almera 18.
Lapho kwakhiwa indawo yokuphehla amandla, kwasetshenziswa ubuchwepheshe obuphambili bokukhiqiza. Isibonelo, ama-camshaft, i-drive chain kanye nenani lezinye izingxenye zokuhlikihla kwakumbozwe ngenhlanganisela evimbela ukukhuhlana. Ukuze unciphise amandla okungqubuzana, iziketi ze-piston zine-graphite inserts.
I-Aluminium cylinder block enezinsimbi ezisansimbi. Ikhanda le-cylinder lifakwe ama-camshaft amabili nama-valve angu-12. Izinxephezelo ze-Hydraulic azinikeziwe, okudala ukuphazamiseka okwengeziwe ekunakekeleni. Ukucaciswa kwamavalvu ashisayo kufanele kulungiswe ngemuva kwamakhilomitha ayizinkulungwane ezingama-60 ngokukhetha ama-pusher.
Isikhathi se-chain drive. Isilawuli sesigaba sifakwe ku-camshaft yokungenisa.
Injini ifakwe i-low-inertia turbocharger kanye ne-intercooler.
Iphampu kawoyela eguquguqukayo. Uhlelo lwe-MPI lokujova uphethiloli. Umjovo kaphethiloli osabalalisiwe uvumela ukufakwa kwe-LPG.
Umehluko omkhulu phakathi kwenjini ye-H4D ne-H4Dt ubukhona be-turbocharging kweyakamuva, ngenxa yalokho ezinye izici zobuchwepheshe zishintshiwe (bheka ithebula).

Kusho ukuthini ukuguqulwa kwe-H4D 400?
Injini evuthayo yangaphakathi ye-H4D 400 ayihlukani kakhulu nesisekelo semodeli ye-H4D. Amandla 71-73 hp. s at 6300 rpm, torque 91-95 Nm. Isilinganiso sokucindezela 10,5. Umkhathi.
Ezomnotho. Amafutha asetshenziswa emgwaqeni onguthelawayeka angamalitha angu-4,6.
Kuyisici ukuthi kusukela ngo-2014 kuya ku-2019 yafakwa ku-Renault Twingo, kodwa ... ngemuva kwemoto.
Ngaphezu kwalesi modeli, injini ingatholakala ngaphansi kwe-hood ye-Smart Fortwo, i-Smart Forfour, i-Dacia Logan no-Dacia Sandero.
Ukuthembeka, ubuthakathaka, ukugcina
Ukuthembeka
I-H4Dt ithathwa njengenjini ethembekile nesebenzayo. Kukhona amandla anele kanye ne-torque ukudala ukudonsa okuhloniphekile ngevolumu encane kangaka.
Idizayini elula yesistimu yokuphakelwa kukaphethiloli kanye nayo yonke injini yomlilo yangaphakathi iyonke kuwukhiye wokuthembeka kwayo.
Ukusetshenziswa kukaphethiloli okuphansi (3,8 amalitha kuthelawayeka**) kukhombisa ukusebenza kahle okuphezulu kweyunithi.
I-anti-friction coating yezindawo zokuhlikihla ze-CPG azigcini nje ukwandisa impilo yesevisi, kodwa futhi kwandisa ukuthembeka kwenjini.
Ngokwemibono yochwepheshe bezimoto kanye nokubuyekezwa kwabanikazi bezimoto, le njini, ngokulungiswa okufika ngesikhathi kanye nekhwalithi ephezulu, ingahamba izinkulungwane ezingama-350 km ngaphandle kokulungiswa.
**yeRenault Clio eshintshwayo.
Izindawo ezibuthakathaka
Injini yomlilo yangaphakathi ikhishwe muva nje, ngakho-ke alukho ulwazi olubanzi mayelana namaphuzu ayo abuthakathaka. Noma kunjalo, imilayezo ivela ngezikhathi ezithile ukuthi i-ECU kanye nesilawuli sesigaba asikathuthukiswa ngokugcwele. Kunezikhalazo ezingazodwa mayelana nokushiswa kukawoyela okuvele ngemuva kokugijima amakhilomitha ayizinkulungwane ezingama-50. Ochwepheshe besevisi yezimoto babikezela ukuthi kungenzeka ukwelula uchungechunge lwesikhathi. Kodwa asikho isiqinisekiso salesi sibikezelo okwamanje.
Izinjini ezikhiqizwe ngo-2018-2019 zazine-firmware ye-ECU yekhwalithi embi. Ngenxa yalokho, kwaba nezinkinga ngejubane elintantayo elingenzi lutho, ukuqala injini emakhazeni, kanye ne-turbine (yacisha yodwa, ikakhulukazi lapho ishayela kancane ikhuphuka). Ekupheleni kuka-2019, leli phutha ku-ECU laqedwa ngochwepheshe bomkhiqizi.
Kunolwazi oluncane kakhulu mayelana nokuvela kwesishishi sikawoyela. Mhlawumbe iphutha likumnikazi wemoto ngokuvela kwenkinga enjalo (ukwephulwa kwezincomo zomkhiqizi wokusebenza kwenjini). Mhlawumbe lena imiphumela yesici sokukhiqiza. Isikhathi sizovela.
Impilo yesevisi yabalawuli besigaba ezinjinini zaseFrance ayikaze ibe yinde kakhulu. Kulesi simo, isixazululo kuphela ukufaka esikhundleni seyunithi.
Ukuthi uchungechunge lwesikhathi luzonwebeka yini kusesigabeni samaqabunga etiye.
Ukulondolozeka
Uma sicabangela umklamo olula weyunithi, kanye ne-cylinder block yayo, singacabanga ngokuphepha ukuthi ukugcinwa kwenjini kufanele kube kuhle.
Ngeshwa, alukho ulwazi lwangempela ngalesi sihloko okwamanje, njengoba injini yomlilo yangaphakathi isisebenze isikhathi esifushane uma kuqhathaniswa.
I-Renault H4D, izinjini ze-H4Dt zizibonakalisa ngempumelelo ekusebenziseni kwansuku zonke. Naphezu komthamo wabo omncane, babonisa imiphumela emihle yokudonsa, ejabulisa abanikazi bezimoto.
