Nissan SR18DE injini

Mitundu ya injini ya SR imaphatikizapo ma injini a silinda anayi okhala ndi 1.6, 1.8 ndi 2 malita. Zinali zozikidwa pa chipika cha aluminiyamu ya silinda ndi mutu wa silinda, ndipo manifolds anali opangidwa ndi chitsulo. Magawo amagetsi awa anali ndi magalimoto apakati ndi ang'onoang'ono ochokera ku Nissan. Kuphatikiza apo, ma mota ena anali ndi turbine. Mndandanda wa injini za SR walowa m'malo mwa mtundu wa CA.

Japanese SR18DE wagawo mphamvu "Nissan" - 1,8-lita injini, kupanga umene unayamba mu 1989 ndipo anapitiriza mpaka 2001. Wadzikhazikitsa ngati injini yokhazikika bwino popanda zolakwika ndi matenda.

Mbiri ya injini ya Nissan SR18DE

Chomera chamagetsi cha SR18DE kuchokera ku Nissan chinapangidwa nthawi yomweyo ngati injini zonse zokondedwa za-lita SR20 ndi injini yamasewera ya 1,6-lita SR16VE. SR18DE idayikidwa ngati injini yabata komanso yotsika mtengo yokhala ndi malita 1,8.

Maziko a ntchito yake anali awiri lita SR20 injini ndi zosintha zina mu mawonekedwe a pistoni ang'onoang'ono ndi mavavu kudya ndi utsi. Madivelopa adasinthanso ma camshafts, potero amasintha magawo ndi magawo okweza. Komanso, gawo latsopano ulamuliro anali ndi udindo ntchito zonse injini, koma apo ayi akadali SR20DE yemweyo, 1,8-lita okha.

Kuti mudziwe! Kuphatikiza pa injini ya SR18DE, yomwe idasiyanitsidwa ndi jekeseni wogawa mafuta, idapangidwanso ndi injini ya 1,8-lita SR18Di, koma ndi jekeseni imodzi, motero, mutu wina wa silinda (HC)!

Monga mtundu wake wakale wa malita awiri, SR18DE inali ndi zonyamula ma hydraulic, zomwe zimakuthandizani kuti muiwale za kusintha mavavu. The camshafts wa makina gasi kugawa ali ndi unyolo pagalimoto (Timing Chain), amene palokha ndi dongosolo lodalirika kwambiri kuti akhoza kukhala oposa 200 zikwi Km. Chithunzi cham'munsi chikuwonetsa wogawa zoyatsira (wogawa) SR18DE:

Chaka chomaliza cha kupanga injini iyi ndi 2001. M'chaka chomwecho, cholandirira SR18DE chinayambitsidwa - chipangizo chamagetsi chatsopano komanso chapamwamba kwambiri cha QG18DE.

Kuti mudziwe! Mphamvu yamagetsi ya SR18DE ili ndi makina ojambulira mafuta ambiri a MPI (Multi-Point Injection), omwe amafanana ndi injini zoyambira. Komabe, pa injini zamtsogolo, makina atsopano a GDI (Gasoline Direct Injection) adayikidwa, omwe sapereka mafuta kuzinthu zambiri, koma mwachindunji ku chipinda choyaka moto!

Zomwe zimagwiritsidwa ntchito pa injini ya SR18DE

Injini za mzere wa SR, kuphatikizapo SR18DE, zimasiyanitsidwa ndi kudalirika kwawo komanso kulimba. Ngakhale kuti alibe zofooka zapadziko lonse lapansi, nthawi zina pamakhala zopanda pake zoyandama, zomwe zikuwonetsa wowongolera liwiro lolephera.

XX ikhoza kusinthidwa ndikulowetsa chowongolera. Kuthamanga kwa injini yoyandama kungasonyezenso kugwiritsa ntchito mafuta otsika kwambiri. Komanso, tikayang'ana ndemanga za eni injini iyi, nthawi ndi nthawi zimachitika vuto la misa mpweya otaya kachipangizo (DMRV).

Kawirikawiri, gwero la makina ogawa gasi (GRM) ndi pafupifupi makilomita 300, kenako unyolo wa nthawi ukhoza kugwedezeka. Ichi ndi chizindikiro choyamba kuti chatambasulidwa ndipo chiyenera kusinthidwa.

Zofunika! Ndikofunikira kwambiri kuwunika pafupipafupi kuchuluka kwamafuta a injini mu injini. Zowonadi, panthawi yanjala yamafuta, gulu lonse la pisitoni limayamba kuvala, kuphatikiza zolemba zazikulu ndi zolumikizira ndodo ndi zingwe za crankshaft!

Chithunzi cham'munsi chikuwonetsa zinthu zamakina ogawa gasi:

Ngakhale kuti SR18DE ili ndi kudalirika kwakukulu sikumanyalanyaza zolakwika zina zomwe zimapezeka mu injini zonse. Mwachitsanzo, injini yomwe singayambike kapena kuyamba bwino kuzizirira ingasonyeze vuto la spark plug kapena pampu yamafuta yomwe siyikutulutsa mphamvu yoyenera. Ndikofunikira kwambiri kuyang'anira kutentha kwa injini, yomwe imatha kusokonezedwa chifukwa cha kusagwira bwino ntchito kwa thermostat, yomwe sikutsegula kuzungulira kwakukulu kwa kuzizira kozizira.

Kuti mudziwe! Kuwonjezera pa mavuto injini SR18DE, palinso mavuto ndi kufala basi - nthawi zambiri magiya basi kutha, zomwe zimabweretsa kukonza kapena m'malo gearbox lonse. Mbali yofunika ya mayunitsi awiriwa ndi kuti akugwirana wina ndi mzake, ndiko kuti, injini ndi kufala zodziwikiratu zokhazikitsidwa ndi mapilo apadera, amene akugwira injini ndi gearbox wachiwiri. Kuti muchotse gearbox yodziwikiratu, ndikofunikira kukhazikitsa fulcrum yowonjezera pansi pagalimoto!

Kutentha kwa injini kungathe kusokoneza kukhulupirika kwa pistoni ndi liner yamphamvu, komanso kuyendetsa GCB, zomwe zidzachititsa kuti kuchepa kwa injini psinjika kapena m'malo mutu yamphamvu. Ponena za dongosolo lozizira, tikulimbikitsidwa kuti tisinthe mpope (pampu yamadzi) pamodzi ndi m'malo mwa kuyendetsa nthawi. Ena eni magalimoto okhala ndi injini za SR18DE amadandaula za kuchuluka kwa kugwedezeka kwa injini. Pano, kukwera kwa injini, komwe kwatha ndi kutaya kulimba kwake, kungakhale chifukwa.

Kuti mudziwe! Kutentha kotsegula kwa thermostat kumasiyana kuchokera ku 88 mpaka 92 madigiri. Choncho, ngati injini yalowa mumachitidwe ake opareshoni, ndipo ozizira akadali kuzungulira mu bwalo laling'ono (popanda kulowa mu rediyeta), ndiye izo zikusonyeza kupanikizana thermostat!

Pansipa pali chithunzi cha malo azinthu zazikulu za injini: thermostat, starter, ICE relay kukhazikitsa malo, ndi zina zotero.

Mphamvu ya SR18DE imatha kusinthidwa, ngakhale izi zidzawonjezera mphamvu zake pang'ono. Ndizosavuta kusinthana pa SR20DET/SR20VE ndipo kale mu mtundu woyambira, kutulutsa mphamvu kudzakhala 200 hp. SR20DET itatha kulimbikitsa kutulutsa 300 hp.
