Mitsubishi 4m40 injini

Dizilo yatsopano 4M40

Iyi ndi in-line 4-cylinder mphamvu ya dizilo yokhala ndi camshaft yapamwamba. 4m40 ili ndi chipika chachitsulo choponyedwa ndi mutu wa silinda wa theka-aluminium. Mphamvu ya injini ndi 2835 cmXNUMX.

Kufotokozera kwa injini

Kuyika kulikonse kwa injini kuyenera kuyendetsedwa ndi mphamvu za inertial. 4m40 ndi chimodzimodzi. 2 ma shafts owonjezera omwe ali ndi udindo pa ntchitoyi. Amayendetsedwa ndi magiya apakatikati kuchokera ku crankshaft, ndipo amakhala motere: kumanja kumanja ndi pansi kumanzere. The crankshaft injini ndi chitsulo, zochokera 5 mayendedwe. Pistoni yamtundu wapadera, semi-aluminium, imalumikizidwa ndi ndodo yolumikizira pogwiritsa ntchito pini yoyandama.

Mphetezo zimapangidwa ndi chitsulo chosungunuka. Zipinda zowotcha za Swirl (VCS) zimayikidwa pamutu wa silinda, zomwe zimapangitsa kuti ziwonjezeke chizindikiro chamafuta. Ndipotu, izi ndi zipinda zachitsulo zotsekedwa zomwe zimayikidwa pamutu wa silinda. Mkati mwake muli choyikapo chitsulo cha ceramic ndi chophimba chozungulira chomwe chimapanga kusiyana kwa mpweya ndi mkati mwa chipindacho. Kuwonjezera kuonetsetsa kuyaka wathunthu wa mafuta, ndi VCS amalola kuchepetsa kuchuluka kwa nayitrogeni oxides.

Camshaft ya injini ya 4m40 ndi pampu yamafuta othamanga kwambiri imayendetsedwa kuchokera ku crankshaft pogwiritsa ntchito giya.

Kugwira ntchito ndi kusamalidwa kwa injini ya dizilo

4m40 imadziwika bwino kuti injini ya Pajero 2. Idayikidwa koyamba pa SUV iyi mu 1993. Dizilo idayambitsidwa kuti ilowe m'malo mwa 4d56 yakale, koma yomalizayo idapangidwabe pambuyo pake kwa nthawi yayitali.

Chinthu choyamba chimene akatswiri pa magalimoto dizilo kulabadira ndi chopangira magetsi - gwero lake ndi 4m40 m'dera la 300 zikwi Km. Kamodzi pachaka, onetsetsani kuti mukuyeretsa valavu ya EGR. Kawirikawiri, galimotoyo ndi yodalirika, yokonza bwino nthawi zonse komanso yowonjezera mafuta a dizilo ndi mafuta abwino, imakhala yosachepera makilomita 350 zikwi za galimoto.

Kusintha kwa valve pa 4m40

Pambuyo pa makilomita 15 pa injini, m'pofunika kufufuza / kusintha mavavu. Zilolezo pa "hot" injini kuyaka mkati ayenera motere:

• pa mavavu kudya - 0,25 mm;
• kwa maphunziro - 0,35 mm.

Ndikofunikira kwambiri kusintha mavavu pa 4m40, komabe, monga pamagetsi ena. Dizilo 4m40 ndi makina ovuta kwambiri, okhala ndi magawo osiyanasiyana. Kuti chilichonse chizigwira ntchito bwino kwa nthawi yayitali, ndikofunikira kukonza nthawi yake.

Kusintha kwa valve 4m40

Mavavu ndi "mbale" ndi ndodo zazitali. Ikani mu phula la silinda. Pali ma valve awiri pa silinda. Akatseka, amapumira pa zishalo zopangidwa ndi zitsulo zolimba. Kuti zinthu za "mbale" zisawonongeke, ma valve amapangidwa ndi ma alloys apadera omwe amatha kupirira katundu wochuluka wamakina ndi kutentha.

Ma valve ndi mbali zofunika kwambiri za dongosolo la nthawi. Nthawi zambiri amagawidwa m'malo olowera komanso otuluka. Zoyambazo zimakhala ndi udindo wa kusakaniza kwa mafuta osakaniza, otsirizawa ndi mpweya wotulutsa mpweya.

M'kati mwa ntchito yaitali injini, "mbale" kukula, ndi ndodo yaitali. Chifukwa chake, miyeso ya mipata pakati pa makamera akukankhira ndi malekezero amasinthanso. Ngati zopotokazo zikupitilira kuchuluka kovomerezeka, kusintha kovomerezeka kudzafunika.

Ndikofunikira kwambiri kupanga masinthidwe munthawi yake. Mwachitsanzo, ndi mipata yaying'ono, "kuwotcha" kudzachitika mosalephera - ntchito yogawa gasi idzasokonekera, chifukwa muye wochuluka kwambiri udzaunjikana pagalasi la "mbale". Ndi mipata yowonjezereka, ma valve sangathe kutsegula kwathunthu. Chifukwa cha izi, mphamvu ya injini idzachepetsedwa kwambiri, ma valve amayamba kugogoda.

Kuyendetsa nthawi yama chain: zabwino ndi zoyipa

Injini ya 4m40 imagwiritsa ntchito mizere iwiri ya nthawi. Zimatenga nthawi yayitali kuposa lamba - pafupifupi, pafupifupi makilomita 250. Iyi ndi njira yoyesedwa nthawi yomwe yatsimikizira kuti ndiyodalirika. Kuyendetsa unyolo kumakhala kolimba, ngakhale kuli ndi zovuta zingapo.

1. Kuwonjezeka kwa phokoso la injini ya 4m40 kumachitika ndendende pogwiritsa ntchito makina oyendetsa nthawi. Komabe, kuipa kumeneku kumalipidwa mosavuta ndi shvi yoyendetsedwa bwino ya chipinda cha injini.
2. Pambuyo makilomita 250, unyolo umayamba kutambasula, phokoso la khalidwe likuwonekera. Zoona, izi sizikulonjeza mavuto aakulu - gawo silimagwedezeka pa magiya, magawo a GDS samasokera, injini ikupitiriza kugwira ntchito mokhazikika.
3. Ma motor chain chain ndi olemera mofanana ndi ma motors oyendetsedwa ndi malamba. Izi zimakhudza kwambiri ntchito zopanga zamakono. Monga mukudziwira, pa mpikisano wopikisana nawo, aliyense ankaganizira kwambiri za injini zoyatsira mkati, kotero akuyesera kuchepetsa kukula kwa mphamvu ndi kulemera kwake. Chingwe cha mizere iwiri sichimakwaniritsa miyezo yotereyi mwanjira iliyonse, kupatula kuti mzere umodzi ndi wopapatiza, koma si wa 4m wamphamvu wa dizilo.
4. Kuyendetsa unyolo kumagwiritsa ntchito hydraulic tensioner, yomwe imakhudzidwa kwambiri ndi kuthamanga kwa mafuta. Ngati "kudumpha" pazifukwa zilizonse, mano a unyolo amayamba kutsetsereka ngati pagalimoto wamba.

Chingwe cha sitima yamagetsi

Koma kuyendetsa unyolo, pamodzi ndi minuses, kumakhala ndi zowonjezera zambiri.

1. Unyolo ndi gawo la mkati mwa injini, osati linanena bungwe ngati lamba wosiyana. Izi zikutanthauza kuti imatetezedwa bwino ku dothi, fumbi ndi madzi.
2. Chifukwa chogwiritsa ntchito ma chain drive, ndizotheka kukhazikitsa bwino magawo a GDS. Unyolo suyenera kutambasulidwa kwa nthawi yayitali (makilomita 250-300), chifukwa chake, sizimasamala za kukula kwa injini - injiniyo sidzataya mphamvu yake yoyamba pakuwonjezeka komanso kuthamanga kwambiri.

HPFP 4m40

Injini ya 4m40 poyambirira idagwiritsa ntchito makina ojambulira pampu. Pampuyo inkagwira ntchito ndi turbine ya MHI ndi intercooler. Ili linali mtundu wa 4m40, womwe ukupanga 125 hp. pa 4000 rpm.

Kale mu May 1996, opanga anayamba kugwiritsa ntchito injini ya dizilo ndi turbine EFI. Mtundu watsopanowu unapanga 140 hp. pa liwiro lomwelo, makokedwe anawonjezeka, ndipo zonsezi anapindula pogwiritsa ntchito mtundu watsopano wa jekeseni mpope.

Pampu yothamanga kwambiri ndi chinthu chofunikira kwambiri pa injini ya dizilo. Chipangizocho ndi chovuta, chopangidwa kuti chipereke mafuta ku injini pansi pa mphamvu yamphamvu. Pakachitika vuto, kuvomerezedwa kwa akatswiri kukonza kapena kusintha pazida zapadera kumafunikira.

HPFP 4m40

Nthawi zambiri, mpope wa dizilo wa 4m40 umalephera chifukwa chamafuta otsika komanso mafuta. Fumbi, tinthu tating'ono ting'onoting'ono tadothi, madzi - ngati alipo mumafuta kapena mafuta opaka mafuta, amalowa mu mpope, kenako amathandizira kuwonongeka kwa awiriawiri okwera mtengo. Kuyika komaliza kumangochitika ndi zida zomwe zili ndi kulekerera kwa micron.

Ndikosavuta kudziwa kusagwira ntchito kwa mpope wa jakisoni:

• ma nozzles omwe amapopera ndi kubaya mafuta a dizilo amawonongeka;
• kuchuluka kwa mafuta;
• kuchuluka kwa utsi wothira;
• phokoso la injini ya dizilo likuwonjezeka;
• mphamvu imachepa;
• zovuta kuyamba.

Monga mukudziwa, Pajero wamakono, Delica ndi Pajero Sport, okonzeka ndi 4m40, ECU - jekeseni mafuta amalamulidwa ndi dongosolo lamagetsi. Kuti mudziwe vutolo, muyenera kulumikizana ndi dizilo, komwe kuli zida zoyesera akatswiri. M'kati mwa njira zowunikira, ndizotheka kuzindikira kuchuluka kwa kuvala, moyo wotsalira wa zida zotsalira za dizilo, kufanana kwamafuta, kukhazikika kwamphamvu, ndi zina zambiri.

Mapampu a jakisoni wamakina, omwe adayikidwa pamitundu yoyambirira ya 4m40, sanathenso kupereka kulondola kwa dosing koyenera, popeza mainjiniya adasinthiratu mapangidwewo, ndikubweretsa ku miyezo yatsopano ya ECO. Miyezo yotulutsa utsi inali yolimba kulikonse, ndipo mtundu wakale wa pampu yothamanga kwambiri unatsimikizira kukhala wosapanga bwino.

Kwa machitidwe apakompyuta, adabwera ndi mapampu atsopano a jekeseni wamafuta amtundu wogawa, ophatikizidwa ndi owongolera oyendetsedwa. Anapangitsa kuti zitheke kusintha malo a dispenser ndi valavu yojambulira mafuta odziwikiratu.

4m40 yadzikhazikitsa yokha ngati mphamvu yamphamvu komanso yodalirika. Komabe, nthawi siimaima - 3m4 latsopano ndi buku ntchito malita 41 anali kale anaika pa Pajero 3,2. Injini iyi ndi chifukwa cha zaka zambiri za ntchito ya akatswiri omwe adazindikira ndikuchotsa zofooka za zabwino, koma zachikale za 4m40.
