1.5 dci injini - ndi gawo liti lomwe limagwiritsidwa ntchito pamagalimoto a Renault, Dacia, Nissan, Suzuki ndi Mercedes?

Poyambirira, ndikofunikira kudziwa kuti pali zosankha zambiri pagawoli. Injini ya 1.5 dci ikupezeka pazosintha zopitilira 20. Pali kale mibadwo 3 ya injini zamagalimoto, zomwe zimakhala ndi mphamvu zosiyana. M'nkhaniyi mupeza mfundo zofunika kwambiri!

1.5 dci injini ndi kuwonekera kwake. Kodi gulu loyamba linali lotani?

Chida choyamba chomwe chidawonekera pamsika chinali K9K. Anawonekera mu 2001. Inali injini ya turbo ya ma silinda anayi. Inalinso ndi njanji wamba ndipo idaperekedwa mosiyanasiyana mphamvu kuyambira 64 mpaka 110 hp. 

Kusiyanitsa pakati pa mitundu yoyendetsa payokha kumaphatikizapo: majekeseni osiyanasiyana, ma turbocharger kapena ma flywheels kapena ena. Injini ya 1.5 dci imasiyanitsidwa ndi chikhalidwe chapamwamba cha ntchito, ntchito yabwino mumitundu yamphamvu kwambiri komanso zachuma - kugwiritsa ntchito mafuta pafupifupi malita 6 pa 100 km. 

Mitundu yosiyanasiyana ya 1.5 dci - zenizeni zamitundu yamagalimoto

Ndikoyenera kuphunzira zambiri zamitundu yosiyanasiyana ya injini ya 1.5 dci. Zofooka kwambiri, zomwe zimapanga 65 hp, zilibe zida zoyandama. Komanso alibe chosinthira geometry turbine ndi intercooler. Pankhani ya injini iyi, jakisoniyo adapangidwa mogwirizana ndi kampani yaku America ya Delphi Technologies. Imagwira ntchito pamagetsi a 1400 bar. 

Chithunzi cha 82hp imasiyana chifukwa imakhala ndi intercooler komanso kuthamanga kwa turbo kuchokera pa 1,0 mpaka 1,2 bar. 

100 hp mtundu Ili ndi flywheel yoyandama komanso turbine ya geometry yosinthika. Kuthamanga kwa jakisoni ndikokweranso - kuchokera pa 1400 mpaka 1600 bar, ngati kuthamanga kwa turbo boost, pa 1,25 bar. Pankhani ya unit iyi, mapangidwe a crankshaft ndi mutu asinthidwanso. 

Gulu latsopano la unit kuyambira 2010

Kumayambiriro kwa 2010, mbadwo watsopano wa unit unayambitsidwa. Injini ya 1.5 dci yakwezedwa - izi zikuphatikiza valavu ya EGR, turbocharger, pampu yamafuta. Okonzawo adaganizanso kugwiritsa ntchito makina ojambulira mafuta a Siemens. Njira Yoyambira-Stop imayikidwanso, yomwe imangozimitsa ndikuyambitsa gawo loyaka moto - kuti muchepetse nthawi yopumira injini ndikuchepetsa kuwononga mafuta, komanso kuchuluka kwa kawopsedwe ka mpweya wotulutsa mpweya.

Kodi injini ya 1,5 dci ndi yamtengo wapatali bwanji?

Ubwino waukulu wa dipatimentiyi ndi, choyamba, kukwera mtengo komanso chikhalidwe chapamwamba cha ntchito. Mwachitsanzo, injini ya dizilo mu galimoto ngati "Renault Megane" amadya malita 4 pa 100 Km, ndipo mu mzinda - 5,5 malita pa 100 Km. Amagwiritsidwanso ntchito pamagalimoto monga:

• Renault Clio, Kangoo, Fluence, Laguna, Megane, Scenic, Thalia ndi Twingo;
• Dacia Duster, Lodgy, Logan ndi Sandero;
• Nissan Almera, Micra K12, Tiida;
• Suzuki Jimny;
• Mercedes class A.

Komanso, ndi kuyaka kwabwino kotereku, injiniyo imakhala ndi mawonekedwe osavuta, zomwe zimapangitsa kuti ikhale yotsika mtengo. Injini ya 1.5 dci imakhalanso yolimba. Komabe, ziyenera kukumbukiridwa kuti kulephera kwa node kumatha kuwonjezeka kwambiri pambuyo pa mtunda wa makilomita 200. km.

Kulephera kwa 1.5 dci. Kodi zolakwa zofala kwambiri ndi ziti?

Mafuta abwino amatengedwa kuti ndi chimodzi mwazinthu zomwe zimayambitsa kulephera kwa ma unit. Ichi ndi chifukwa chakuti injini salola otsika khalidwe mafuta. Izi zitha kukhala zowona makamaka pa njinga zopangidwa ndi zigawo za Delphi. Injector mumikhalidwe yotere imatha kugwiritsidwa ntchito pambuyo pa 10000 km. 

Madalaivala omwe amagwiritsa ntchito magalimoto okhala ndi mayunitsi amphamvu kwambiri amadandaulanso za mavuto. Ndiye pali zovuta zomwe zimagwirizanitsidwa ndi valavu ya EGR yowonongeka, komanso flywheel yoyandama. Kukonzanso kokwera mtengo kumalumikizidwanso ndi fyuluta yowonongeka ya particulate, yomwe, komabe, ndizovuta kwa injini zamakono zamakono. 

Nthawi zina pangakhale kulephera kokhudzana ndi zamagetsi pagalimoto. Choyambitsa kwambiri ndi dzimbiri zomwe zimachitika pakuyika magetsi. Nthawi zina izi ndi chifukwa cha kuwonongeka kwa kukakamizidwa kapena ma sensor a crankshaft. Poganizira zochitika zonse zomwe zachitika chifukwa cha kuwonongeka, ndi bwino kutsindika udindo wa ntchito yolondola ya galimotoyo, komanso kukonza magetsi.

Momwe mungasamalire gawo la 1.5 dci?

Kuyang'ana mozama kumalimbikitsidwa pakati pa 140 ndi 000 km. Chifukwa cha ntchito yotereyi, mavuto ndi makina amagetsi kapena jekeseni amatha kuchitika. 

Ndikoyeneranso kusinthira jekeseni nthawi zonse. Adapangidwa ndi Delphi, iyenera kusinthidwa pambuyo pa 100 km. Siemens, kumbali ina, ndi yodalirika kwambiri ndipo imatha nthawi yaitali, koma kuchotsa dongosolo lakale ndi latsopano kudzakhala vuto lalikulu la ndalama.

Kuti mugwiritse ntchito mopanda mavuto kwa nthawi yayitali, ndikofunikira kusintha mafuta pafupipafupi. Iyenera kuwonjezeredwa mafuta pa 10000 km iliyonse. Izi zidzakuthandizani kupewa mavuto okhudzana ndi kuwonongeka kwa crankshaft. Chifukwa cha kulephera kumeneku ndi kuchepa kwa mafuta a pampu yamafuta.

Kodi injini ya Renault 1.5 dci ndi injini yabwino?

Malingaliro okhudza gawoli amagawidwa. Komabe, wina angayerekeze kunena kuti chiŵerengero cha anthu odandaula za 1.5 dci chingachepe ngati madalaivala onse azigwiritsa ntchito injini zawo pafupipafupi ndikugwiritsa ntchito mafuta abwino. Pa nthawi yomweyo, French injini dizilo akhoza kulipira ndi ntchito khola ndi bwino kwambiri.
