Emuva ngo-1933, izinkampani ezimbili ezaziwayo zahlanganiswa: iTobato Imono kanye noNihon Sangyo. Akufanelekile ukuya emininingwaneni, kodwa ngemva konyaka igama elisemthethweni le-brainchild entsha yethulwa - i-Nissan Motor Co., Ltd.

Futhi cishe ngokushesha inkampani iqala ukuhlinzeka ngezimoto zakwaDatsun. Njengoba abasunguli beshilo, lezi zimoto zenzelwe iJapan kuphela.

Ngemva kweminyaka, uhlobo lweNissan lungomunye wabaholi ekwakhiweni nasekuthengisweni kwezimoto. Ikhwalithi yaseJapane eyaziwa kakhulu ivezwe ngokucacile kukhophi ngayinye, kumodeli entsha ngayinye.

Umlando wenjini ye-Nissan MR20DE

Amayunithi amandla inkampani "Nissan" (izwe laseJapane) ufanelwe amagama ahlukene. Lezi izinjini eziphila isikhathi eside, zonga kakhulu, zithobela izindinganiso zemvelo ezamukelwa ngokuvamile, futhi azibizi ukuzinakekela nokuyilungisa.

Ukukhiqizwa okukhulu kwe-MR20DE motors kwaqala ngo-2004, kodwa eminye imithombo ithi i-2005 izoba isibalo esinembe kakhudlwana. Sekuyiminyaka eyi-13 ukukhiqizwa kwamayunithi akukamiswa, futhi namuhla kuyaqhubeka nokusebenza kahle. Ngokusho kokuhlolwa okuningi, injini ye-MR20DE ibambe ngokuqinile endaweni yesihlanu mayelana nokuthembeka emhlabeni wonke.

Ukulandelana kokufakwa kwamamodeli ezinkampani ahlukahlukene:

Nissan Lafesta. Iveni yakudala, enethezekile eyabona umhlaba ngo-2004. Injini enamalitha amabili isibe iyunithi ekahle umzimba, ubude bawo cishe 5 amamitha (4495 mm).
Imodeli ye-Nissan A ifana kakhulu nommeleli wangaphambilini. I-Nissan Serena iyiveni elincane, ukucushwa kwalo okuhlanganisa ukufakwa kwamasondo angemuva kanye nawo wonke amasondo.
Nissan bluebird. Imoto, eyaqala ukukhiqizwa ngo-1984 futhi yathola izinguquko eziningi kusukela ngo-1984 kuya ku-2005. Ngo-2005, injini ye-MR20DE yafakwa emizimbeni ye-sedan.
Nissan Qashqai. Okwethulwa emphakathini ngo-2004, futhi ngo-2006 kuphela waqala ukukhiqizwa kwayo ngobuningi. Injini ye-MR20DE, engu-0 litres, isiphenduke isisekelo esihle semoto ekhiqizwa ngemishini ehlukene kuze kube yimanje.
I-Nissan X-trail. Enye ye-crossovers ethandwa kakhulu, ehluke kumamodeli avela kwabanye abakhiqizi ekuhlanganiseni kwayo. Ukuthuthukiswa kwe-Nissan X-trail kwenziwa emuva ngo-2000, kodwa ngo-2003 imoto isivele ithole ukulungiswa kwayo kokuqala.

Injini ye-Nissan MR20DE Kungashiwo ukuthi injini ye-MR20DE, ukubuyekezwa kwayo okuhle kuphela, iyindawo yomphakathi, njengoba ngaphezu kwalezi zinhlobo ezingenhla, nayo yafakwa ku-Renault izimoto (Clio, Laguna, Mégane). Iyunithi izenzele yona njengenjini ethembekile neqinile, enokungasebenzi kahle okungajwayelekile, ikakhulukazi ngenxa yezingxenye ezisezingeni eliphansi.

Lapho uthenga imoto esetshenzisiwe, akubona bonke abashayeli abayithola ngokushesha, njengoba inombolo ingafihlwa ngaphansi kwesendlalelo sokugqwala.

Ukwethenjwa kwenjini

Kuyaziwa ukuthi iyunithi yamandla ye-MR20DE isiphenduke indawo ethembekile ye-QR20DE eyaziwayo, efakwe ezimotweni kusukela ngo-2000. I-MR20DE inempilo ende yesevisi (ukulungiswa kabusha kudinga ukwenziwa kuphela ngemva kwe-300 km), kanye nezakhiwo ezingcono zokusalungiswa.

Phakathi kwezici zokuklama:

Awekho ama-hydraulic lifter. Kungakho, ngokuvela okungazelelwe kokungqongqoza, kuyadingeka ukulungisa ngokushesha ukucaciswa kwe-valve. Yiqiniso, injini izosebenza kanjalo, kodwa kungcono ukusebenzisa ama-washer ambalwa, avame ukusetshenziselwa ukulungiswa, futhi anganciphisi impilo yeyunithi. I-phase regulator nayo ifakwe ku-shaft yokungenisa.
Ukuba khona kochungechunge lwesikhathi. Ngakolunye uhlangothi, lokhu kuhle, kodwa ngakolunye uhlangothi, kusho ukuthi kunezinkinga ezengeziwe. Isibonelo, ngokuhlukahluka kwanamuhla kwabakhiqizi bezingxenye zezimoto, kunzima kakhulu ukuthola ikhwalithi yangempela. Imvamisa, ukushintshwa kwebhande lesikhathi kungadingeka ngisho nangemva kwe-20000 km.
I-Camshaft lobes kanye namajenali e-crankshaft. Isixazululo esinjalo esakhayo sivumela ukunciphisa ukumelana kwangaphakathi kwe-motor futhi kuthuthukise kokubili okusalungiswa kanye nezimfanelo zejubane.
I-throttle ilawulwa iyunithi ye-elekthronikhi, futhi umjovo wamaphuzu amaningi kufanele futhi ugqanyiswe.

Injini ye-Nissan MR20DE Uhlu lwezinkinga ezivame kakhulu zalesi motor luncane kakhulu futhi luhlanganisa izinkinga ezinjalo lapho umshayeli engakwazi ukufika kuphela endlini noma esikhungweni sesevisi, kodwa futhi nokushayela amakhilomitha angaphezu kwekhulu, akukho ukushintshwa kwenjini okusheshayo okudingekayo. Kuphela uma iyunithi yokulawula ihlulekile.

Kodwa, kufanele kukhunjulwe ukuthi le yunithi, ukwethembeka kwayo kuphakeme kakhulu, yadalelwa kuphela ukuhamba okuzolile nokulinganiselwe. Ukushuna ukuthuthukisa izimfanelo zayo zobuchwepheshe ngeke kusebenze. Isibonelo, ngisho nokufaka i-turbine kuzoholela esidingweni sokugaya i-manifold, ukuthenga i-BPG eqinisiwe, ukufaka iphampu kaphethiloli enamandla kakhulu, nokunye ukuthuthukiswa okuningi. Ngemuva kokufaka i-turbine, amandla enjini azokhula abe ngu-300 hp, kodwa insiza yayo izoncishiswa kakhulu.

Uhlu lwamaphutha ajwayelekile nezindlela zokuwaqeda

Njengoba kushiwo ngaphambili, emotweni yomjovo enenjini ye-MR20DE, azikho izinkinga lapho umshayeli engakwazi ukufinyelela lapho eya khona noma esiteshini esiseduze sesevisi futhi kuzodingeka ukulungiswa okuphuthumayo kwesistimu. Kodwa noma kunjalo, kufanele uvimbele ukungasebenzi ngesikhathi, noma, uma kwenzeka, ungayeki ukulungisa unomphela. Ukuzihlola akusiyo njalo indlela enhle yokuphuma kulesi simo.

Inkinga yokuntanta

Ngokuvamile kwenzeka ngisho nasezimotweni ezintsha, i-mileage esanda kuwela uphawu lwe-50000 km. Ijubane elintantayo ligqama kakhulu uma lingenzi lutho, futhi abanikazi bezimoto abaningi, ngaphandle kokuzikhandla, ngokushesha bayisa imoto ku-minder noma okhanda amasistimu omjovo. Kodwa ungajahi, khumbula nje idivayisi yeyunithi ye-MR20DE.

Le njini ifakwe i-throttle electronic, ku-damper, okuthi ngokuhamba kwesikhathi, ifomu le-carbon deposits. Ngenxa yalokho - ukunikezwa kukaphethiloli okunganele kanye nomphumela wejubane elintantayo. Indlela yokuphuma ukusetshenziswa okulula koketshezi olukhethekile lokuhlanza, oluthengiswa ngamathini aerosol alula. Kwanele ukusebenzisa ungqimba oluncane lwe-liquid emhlanganweni we-throttle, shiya imizuzu embalwa bese usula ngendwangu eyomile. Imanuwali inencazelo enemininingwane yalo msebenzi.

Ukushisa kwe-motor

Injini ye-Nissan MR20DE Inkinga ivamisile, ngenxa yezingxenye ze-elekthronikhi ezinganele, hhayi ukuthi uhlelo lokupholisa luhlulekile: i-thermostat, iphampu (ipompo ayivamisile ukushintshwa) noma inzwa yesivinini engenzi lutho. Ukushisa injini ngeke kubangele ukuthi ime, i-ECU izomane inciphise isivinini ezingeni elithile, okuzobangela nokulahlekelwa amandla.

Lokhu kwenzeka ngenxa yokuthi izinzwa zokugeleza komoya azisebenzi kahle, noma kunalokho, i-thermistor, eyingxenye yazo. Imvamisa, inzwa yokushisa ingakhuphula ukufundwa ngesigamu ncamashi, okubonwa uhlelo njengokushisisa kwenjini futhi kwehlisa ijubane layo ngenkani. Ukuze usebenze ngekhwalithi ephezulu futhi olungile wesistimu, i-thermistor kufanele ishintshwe.

Ukusetshenziswa kukawoyela okwandisiwe

I-Maslozhor abaningi bayibona njengesiqalo sesikhathi lapho kudingekile ukwenza ukulungiswa okumba eqolo kwenjini. Kodwa akufanele usheshe, njengoba isizathu salokhu kungaba amasongo e-piston noma ama-valve stem seal, impilo yesevisi ephelile. Khona-ke, ngaphezu kokwanda kokusetshenziswa kukawoyela, amadiphozithi angabuye akheke endaweni engaphakathi yesilinda noma lapho amaphistoni atholakala khona. Isilinganiso sokucindezela kumasilinda sincishisiwe.

Izici zikhombisa ukusetshenziswa kukawoyela okuvumelekile kwemfucuza, kepha uma injini idla uwoyela kakhulu, kufanele kuthathwe izinyathelo. Ukushintsha izindandatho, isethi yayo engabizi kakhulu, izodinga ukubandakanyeka kochwepheshe abavela esiteshini sesevisi sekhwalithi. Ngaphambi kokufaka esikhundleni, kuyadingeka ukwenza umsebenzi onjenge-raskosovka - ukuhlanza izindandatho ze-piston kusuka ku-soot, futhi emva kwalokho - hlola ukuthi yikuphi ukucindezela okukhona kumasilinda.

Ukunwetshwa kochungechunge lwesikhathi

Injini ye-Nissan MR20DE Ingadidaniswa ne-throttle evalekile, ngoba izimpawu zifana ncamashi: ukungenzi lutho ngokungalingani, ukwehluleka okungazelelwe enjinini (okufana nokuhluleka kwesinye se-spark plugs), izici zamandla ezincishisiwe, ukungqongqoza ngesikhathi sokusheshisa.

Iketango lesikhathi lidinga ukushintshwa. Intengo yekhithi yesikhathi iyathengeka impela, kodwa futhi ungathenga mbumbulu. Ukushintsha iketango kuyashesha, izindleko zenqubo aziphezulu.

Ukubonakala kwekhwela elibukhali nelingemnandi

Impempe izwakala enjinini engafudunyeziwe ngokwanele. Umsindo uyancipha kancane kancane noma unyamalale ngokuphelele ngemva kokukhuphuka kwezinga lokushisa kwemoto. Isizathu salo mlozi yibhande elifakwe kujeneretha. Uma ngaphandle kungabikho ukukhubazeka okubonakalayo kuyo, khona-ke ibhande le-alternator lingamane liqiniswe lapho i-flywheel itholakala khona. Uma kuvela ama-sprains noma imifantu, khona-ke ibhande le-alternator lingcono ukushintshwa libe elisha.

Ungawashintsha kanjani ama-spark plugs

Ukungasebenzi kahle okungenhla akukubi uma kuqedwa ngesikhathi. Kodwa ukusebenza okulula njenge-torque ye-spark plugs kungaba inhlekelele yangempela, emva kwalokho kuyadingeka ukufaka esikhundleni se-cylinder head chain noma ibhande.

Qinisa ama-spark plug ku-MR20DE motor kuphela ngesikrufu se-torque. Amandla ka-20Nm akumele eqiwe. Uma kusetshenziswa amandla engeziwe, khona-ke ama-microcracks angase avele emicu kubhulokhi, okuzobangela ukuphindaphinda kathathu. Kanye nokukhubeka kwenjini, okukhuphuka ngokulingana namakhilomitha ahanjiwe, inhloko yebhulokhi ingambozwa ngokupholisa, imoto isebenza ngamajerk, ikakhulukazi uma i-HBO ifakiwe.

Ngakho-ke, kuyadingeka ukusebenzisa i-wrench torque. Futhi kungcono ukushintsha ama-spark plugs enjinini ebandayo.

Imaphi amafutha angcono kakhulu ukugcwalisa injini

Ukuze insiza yenjini ye-MR20DE ihambisane nedatha echazwe emibhalweni yezobuchwepheshe, zonke izinto ezisetshenziswayo kufanele zishintshwe ngesikhathi: izihlungi zikawoyela nophethiloli, kanye namafutha. Iphampu kawoyela kufanele futhi ihlolwe ngezikhathi ezithile. Ngaphezu kokushintsha izinto ezisetshenziswayo, ama-valve kufanele alungiswe ngezikhathi ezithile (ukuphila impilo ende yesevisi, kufanele ashintshwe njalo ku-100000 km).

Umkhiqizi wezimoto we-MR20DE weluleka ukusebenzisa kuphela uwoyela wekhwalithi ephezulu, njenge-Elf 5W40 noma i-5W30. Yiqiniso, kanye namafutha, isihlungi sibuye sishintshe. I-Elf 5W40 ne-5W30 ine-viscosity enhle kanye nokuminyana futhi ingahlala isikhathi eside. Kodwa kungcono ukuthi ungashintshi uwoyela njalo ngamakhilomitha angu-15000 7500 (njengoba kuboniswe encazelweni yobuchwepheshe), kodwa ukwenza lo msebenzi kaningi - ngemva kwe-8000-XNUMX km futhi unakekele i-pan injini.

Ngokuqondene nophethiloli, kungcono ukuthi ungalondolozi imali futhi ugcwalise injini ngophethiloli ngesilinganiso se-octane okungenani esingu-95, njengoba ibhukwana lokulungisa lisho. Futhi, manje emakethe kunezithasiselo eziningi ezizosindisa hhayi kuphela uhlelo lukaphethiloli, kodwa futhi nempilo yenjini.
