Renault H4D, H4Dt injini
Zamkatimu
Omanga ma mota aku France akupitilizabe kuchita bwino pakupanga magawo amagetsi ang'onoang'ono. Injini yomwe adapanga yakhala kale maziko amitundu yambiri yamagalimoto amakono.
mafotokozedwe
Mu 2018, malo opangira magetsi atsopano opangidwa pamodzi ndi akatswiri a ku France ndi Japan a Renault-Nissan H4Dt adawonetsedwa ku Tokyo (Japan) Motor Show.
Mapangidwewo adatengera injini ya H4D yomwe idapangidwa mwachilengedwe mu 2014.
H4Dt imapangidwabe ku likulu la kampani ku Yokohama, Japan (monga momwe ilili moyambira, H4D).
H4Dt ndi 1,0 lita atatu silinda turbocharged petulo injini ndi 100 ndiyamphamvu. s pa torque ya 160 Nm.
Zakhazikitsidwa pamagalimoto a Renault:
- Clio V (2019-n/vr);
- Captur II (2020-pano).
Kwa Dacia Duster II kuyambira 2019 mpaka pano, komanso pansi pa code HR10DET ya Nissan Micra 14 ndi Almera 18.
Popanga magetsi, matekinoloje apamwamba adagwiritsidwa ntchito popanga. Mwachitsanzo, ma camshafts, makina awo oyendetsa galimoto ndi zigawo zina zopakapaka zinakutidwa ndi anti-friction compound. Kuti muchepetse kugundana, masiketi a pistoni amakhala ndi ma graphite.
Aluminium cylinder block yokhala ndi zingwe zachitsulo. Mutu wa silinda uli ndi ma camshaft awiri ndi ma valve 12. Ma compensators a hydraulic samaperekedwa, zomwe zimapangitsa kuti pakhale zovuta zina pakukonza. Ma valve otenthetsera amayenera kusinthidwa pambuyo pa mtunda wa makilomita zikwi 60 posankha ma pushers.
Kuyendetsa kwanthawi yayitali. Gawo lowongolera limayikidwa pa camshaft yolowera.
Galimotoyo ili ndi inertia turbocharger yotsika komanso intercooler.
Pampu yamafuta osinthika osiyanasiyana. Fuel system jakisoni wamtundu wa MPI. Jekeseni wamafuta ogawidwa amalola kuyika kwa LPG.
Kusiyanitsa kwakukulu pakati pa injini ya H4D ndi H4Dt ndi kukhalapo kwa turbocharger pamapeto pake, chifukwa chake makhalidwe ena aukadaulo asinthidwa (onani tebulo).

*Zomwe zili m'mabulaketi a injini ya H4D.
Kodi kusinthidwa kwa H4D 400 kumatanthauza chiyani?
The H4D 400 injini kuyaka mkati sasiyana kwambiri ndi m'munsi H4D chitsanzo. Mphamvu 71-73 l. s pa 6300 rpm, makokedwe 91-95 Nm. Compress ratio ndi 10,5. Wolakalaka.
Zachuma. Kugwiritsa ntchito mafuta pamsewu waukulu ndi malita 4,6.
Ndizodziwika kuti kuyambira 2014 mpaka 2019 idayikidwa pa Renault Twingo, koma ... kumbuyo kwagalimoto.
Kuphatikiza pa chitsanzo ichi, injini ingapezeke pansi pa nyumba ya Smart Fortwo, Smart Forfour, Dacia Logan ndi Dacia Sandero.
Kudalirika, zofooka, kusakhazikika
Kudalirika
H4Dt imatengedwa ngati injini yodalirika komanso yothandiza. Pali mphamvu ndi torque yokwanira kuti ipangitse kusuntha koyenera kuchokera ku voliyumu yaying'ono ngati iyi.
Mapangidwe osavuta a dongosolo loperekera mafuta ndi injini yonse yoyaka mkati mwathunthu ndiye chinsinsi cha kudalirika kwake.
Kutsika kwamafuta amafuta (malita 3,8 pamsewu waukulu **) kukuwonetsa kuyendetsa bwino kwa chipangizocho.
Kuphimba odana ndi mkangano wa malo akusisita a CPG sikungowonjezera gwero, komanso kumawonjezera kudalirika kwa injini.
Malinga ndi akatswiri a magalimoto ndi ndemanga za eni galimoto, injini iyi, ndi utumiki wake ndi apamwamba, akhoza kupita 350 zikwi Km popanda kukonza.
** ya Renault Clio yokhala ndi kufalitsa pamanja.
Mawanga ofooka
ICE idawona kuwala posachedwa, kotero palibe chidziwitso chozama pa zofooka zake. Komabe, malipoti nthawi ndi nthawi amawoneka kuti ECU ndi gawo loyang'anira gawo silinakwaniritsidwe. Pali madandaulo akutali okhudza maslozhor omwe adawuka pambuyo pa kuthamanga kwa 50 km. Akatswiri oyendetsa magalimoto amalosera za kuthekera kotambasula nthawi. Koma palibe umboni wa kulosera uku.
Ma injini opangidwa mu 2018-2019 anali ndi firmware yotsika kwambiri ya ECU. Zotsatira zake, panali zovuta zoyandama zopanda pake, kuyambitsa injini nyengo yozizira ndi turbine (inazimitsa yokha, makamaka ikayenda pang'onopang'ono kukwera). Kumapeto kwa 2019, kusagwira bwino ntchito uku ku ECU kunathetsedwa ndi akatswiri opanga.
Pali zambiri zochepa zokhudza chiyambi cha maslozhora. Mwina vuto liri ndi eni galimoto pakuwoneka ngati vuto (kuphwanya malingaliro a wopanga injiniyo). Mwina izi ndi zotsatira za ukwati wa fakitale. Nthawi idzawoneka.
Moyo wa owongolera magawo pa injini zaku France sunakhalepo motalika kwambiri. Pankhaniyi, njira yokhayo yotulukira ndiyo kulowetsa node.
Kaya unyolo wanthawi utha kutambasulidwa akadali pamlingo wongoganizira za khofi.
Kusungika
Popeza mawonekedwe osavuta a unit, komanso chipika chake chokhala ndi manja, titha kuganiza kuti kusungika kwagalimoto kuyenera kukhala kwabwino.
Tsoka ilo, palibe chidziwitso chenicheni pamutuwu pano, popeza injini yoyaka mkati yakhala ikugwira ntchito kwakanthawi kochepa.
Renault H4D, H4Dt injini bwinobwino kutsimikizira okha ntchito tsiku ndi tsiku. Ngakhale kuti voliyumu yaying'ono, amawonetsa zotsatira zabwino zokoka, zomwe zimapangitsa eni galimoto kukhala osangalala.
