Uchungechunge lwezinjini zikadizili ezingama-6-cylinder ezimise okwe-V. Umjovo wamafutha uqondile, wenziwa nge-turbocharger yokukhiqiza kwayo. I-motor iye yakhiqizwa kusukela ngo-2005, iklanyelwe ukushintsha injini ye-OM647.

Idatha ejwayelekile mayelana nenjini ye-OM642

Imoto OM642

Ukuze uthole ukusebenza kahle okukhulu kwesitshalo samandla, umenzi wethule ukusetshenziswa kwamasilinda amasha kusukela ngo-2014. Izindonga zabo zazinano-coated. Lokhu kunikeza ukusebenza kahle okukhulu ekusebenziseni uphethiloli futhi kwehlise nesisindo senjini.

I-OM642 ine-engeli ye-camber engu-72 degree futhi ifakwe isizukulwane sesithathu i-Common Rail piezo injector ekwazi ukuletha ibha engu-3. Le njini ithole uhlelo lokusebenza: ubuchwepheshe be-Bluetooth, i-intercooler kanye ne-turbocharger yesizukulwane esisha.

Isilinganiso sokucindezela se-642 singu-18 kuya ku-1. Indlela yesikhathi iwuhlobo lwe-DOHC, nama-camshaft amabili, kukhona ama-valve angu-4 ku-cylinder ngayinye. Idrayivu yesikhathi isetshenziswa ngeketango lensimbi. I-cylinder block nama-pistons zenziwe ngezinto eziphikisayo - i-aluminium alloy. Ama-camshaft amabili abekwe ekhanda le-cylinder ngalinye. Ama-valve alawulwa uhlobo lwe-rocker ingalo.

Injini inomzimba we-aluminiyamu, onikezwe izinsimbi eziphambanayo. Amasilinda kuwo afakwe imikhono ye-cast-iron, efaka isandla ekwenzeni ukuqina okukhulu nokuthembeka kokusebenza. Izinduku zokuxhuma nazo ziqinile, insimbi, futhi i-crankshaft yenziwe ngezinto ezisindayo, ezinobubanzi obugcwele be-shaft.

Umjovo we-OM642

Uhlelo lomjovo weMercedes

Uhlelo lomjovo lusekelwe emsebenzini wezakhi ze-piezoelectric. I-injector enjalo ikwazi ukukhiqiza imijovo efika kwemihlanu ngesikhathi, okunciphisa ukusetshenziswa kukaphethiloli kanye nokukhishwa kwezinto eziyingozi. Iphinde yehlise umsindo wenjini, ithuthukise ukusabela ku-accelerator pedal. Kanye ne-VTG turbocharger, isistimu inikeza amandla aphezulu kanye ne-torque ehehayo kakade kusukela kuma-revs aphansi. I-supercharger ilawulwa nge-elekthronikhi futhi ilungiswe, ngakho-ke amaphutha okulinganisa nawokukhuphula mancane lapha.

Izici zama-injection alolu hlobo:

umjovo ulawulwa yiyunithi yokulawula kagesi yakwaBosch;
ama-injection enziwe ngendlela yama-nozzles, anezimbobo eziyisishiyagalombili;
ukucindezela kwenziwa yi-compressor ye-VTG enobude obuguquguqukayo be-turbine;
i-multitake intake ifakwe isiteshi esengeziwe sokudlula umoya, okwandisa amandla eyunithi futhi kuthuthukise ushintsho lokushaja;
i-cooler ekhethekile yomoya ikuvumela ukuthi unciphise izinga lokushisa lokugeleza uma lidlula ama-90-95 degrees.

I-exhaust ilawulwa isistimu ehlukile

I-AGR iyisistimu yokupholisa i-exhaust ehlukile. Isetshenziselwa ukuthuthukisa izindinganiso zemvelo zemoto. Izingxenye eziningana zihilelekile emsebenzini ngesikhathi esisodwa:

isihlungi sibuyiselwa ngaphandle kokusetshenziswa kwezakhi ezengeziwe - lo msebenzi unikezwe ohlelweni lokulawula injini yomlilo yangaphakathi;
uhlobo olukhethiwe lwe-catalyst lucupha i-ammonia ekhiqizwa ngesikhathi sokushiswa kukaphethiloli we-diesel, ilungiselela into ukuze iphinde iphendule ukuze kuncishiswe ukukhishwa kwegesi;
ngesikhathi esifanayo, i-SCR isebenza njengesihlungi esibamba iphunga lesulfure nokunye.

Ngakho, ukusebenza kwalo lonke uhlelo lokuhlanza olusekelwe kubuchwepheshe be-Bluetec kuyaqinisekiswa.

Ukungasebenzi kahle okuvamile

Inqwaba yezinzwa ezihlukahlukene, ukungena komoya okulungiswayo, ikhono lokukhulula ingcindezi eyengeziwe - ngeshwa, konke lokhu akuqinisekisi ukusebenza okungenazinkinga kwalolu phiko.

Uma unganakile ngokuhlanzeka kwenjini, ingase ingafinyeleli esiphethweni sempilo yayo yokusebenza. Ngakho-ke, i-inlet kufanele igezwe emithonjeni yamafutha angena ngenxa yokusebenza okungalungile kwe-turbine. Umkhiqizi ngokwakhe uncoma ngokuqinile: lapho ushintsha i-turbine, kuyadingeka ukuhlola nokukhipha amafutha ohlelweni lokuthatha!
I-Lubricant nayo ingangena ekuthatheni kanye namagesi e-exhaust. Lokhu sekuchazwe kakade yi-miscalculation eyakhayo, ikakhulukazi uma amafutha engena ngobuningi. Isixazululo ukwenza ukulungisa ngokuhlanza kahle i-intercooler.
Kusukela ekungeneni ngaphakathi kwenqwaba yamafutha, imigudu yangaphakathi iyaphekwa. Ukungasebenzi kahle kwenzeka ohlelweni lwe-damper, okuthi, ngokumangazayo, olubonwa ngumkhiqizi waseJalimane njengomkhuba ojwayelekile ngokuphelele.
Naphezu kokusetshenziswa kwesofthiwe epholile nesimanje, lapho isivinini esiphezulu sidlula, iyunithi yokulawula ayikwazi ukuvikela injini ekubhujisweni. Ikhompyutha imane nje ingakwazi ukukhiya i-throttle, nakuba kungenzeka ukukhawulela amandla futhi uvale i-boost lapho i-turbine igcwele ngokweqile.

Ngaphandle kwalokho, lena injini enhle kakhulu ngokwemishini. Ngesisindo esingaphezu kuka-200 kg, injini ikhiqiza i-260 hp. Nge. kanye ne-torque engu-600 Nm. Iketanga lesikhathi lisezingeni eliphezulu, aliwohloki. Ukuthunjwa kumasilinda akuvamile kakhulu, futhi cishe azikho izinkinga kumshini we-valve. Ngamafuphi, le moto ihluke ngokuphelele kulezo zinjini ezenziwe kuphela ngokucabangela izindinganiso zemvelo. Amayunithi amaningi esimanje anjalo nje - anomklamo oyinkimbinkimbi futhi ongathembekile.

Ikati 66	В целом мотор ОМ 642 зарекомендовал себя довольно надежным. Болячки начинают проявляться на пробеги от 150-200 тысяч, хотя все больше встречаю машины со скрученным пробегом 100-120 тысяч. И всегда радует удивление хозяина автомобиля “как так, мне же друг продал, не может быть такого!! А в итоге владелец машины тратит кругленькую сумму на ремонт лишь потому, что при покупке авто он не удосужился сделать нормальную диагностику автомобиля у официалов или в нормальном сертифицированном сервисе, доверившись другу или частному лицу. Дорогие форумчане, покупая машину за 1000000 или больше найдите 5-10 тысяч на комплексную диагностику, уверяю Вас это спасет от многих проблем и сохранит Вам кругленькую сумму. Вернемся к теме поста, на пробеги 150-200 начинают отказывать вспомогательные системы мотора, как следствие отказ узлов таких как масляный насос, поломка турбины из за низкого давления масла, закисание тяг вихревых заслонок и последующее их заклинивание, отказ системы вентиляции картерных газов и выход из строя сажевого фильтра.
Nkosi	Into esemqoka okufanele uyikhumbule kubo bonke abanikazi bezinjini zikadizili, kungaba Mercedes, BMW, Toyota nanoma yiluphi olunye uhlobo "Injini yeDizili ayiwona umnotho, iwukuphila kwesitolimende nje". Into yokuqala eqala ukungasebenzi kule njini i-crankcase ventilation system. Akuyona imfihlo kunoma ubani, nakuba izwe lethu lingelinye labakhiqizi abakhulu bemithombo yemvelo, linikeza ngokungananazi ama-SUROGATS kubathengi bawo. Ngakho impilo emfushane kawoyela wenjini. Ngizokwenza ukubhuka ngokushesha, ngikweluleka ukuthi ushintshe uwoyela kule moto njalo ngezinkulungwane ezingama-7500. Uhlobo lwasemadolobheni lokusebenza kwemoto, luyithinta kabi imoto. Ukuphushana njalo esiminyaminyeni sezimoto, kanye nesivinini esimaphakathi edolobheni elingamakhilomitha angama-60 akuvumeli injini ukuthi ibambe umoya; ngakho-ke, inani elikhulu lamadiphozithi amapayipi okungenisa umoya we-crankcase, ekungeneni komoya.
AmaRoma	Ngeluleka abanikazi bezimoto ezinalolu hlobo lwenjini lapho igijima izinkulungwane eziyi-100-120, isevisi yesistimu yokungenisa umoya, i-intake manifold, ipayipi lokungenisa umoya. Hlanza konke okungenhla kumadiphozithi kawoyela futhi ngeke ukwazi ukubona imoto yakho. Njengoba uma lokhu kungenziwanga, konke lokhu kungena ku-multifold intake futhi kuhlale kuma-dampers. Uma sithi iyagijima, khona-ke cishe ngamakhilomitha angu-150-200, kuye ngokuthi hlobo luni lokugibela, ama-swirl flaps aqala ukugoba futhi ekugcineni awaphule.
Anadyr	Impela! I-swirl flap servo nayo iyahluleka, ingxenye enkulu ngenxa yamafutha angena kuyo ngaphansi kwepayipi lokungena kwerabha. Malungu athandekayo esithangami, shintsha amabhande enjoloba amabili abomvu epayipi lokungenisa kanye nepayipi lokungenisa umoya njalo ngemva kwezinkulungwane ezingama-20 km. Yebo, ngiyayiqonda intengo ye-800 enye i-300, yayibonakala ingeyona imali eningi "KODWA i-S.KA SHE ayigelezi, kungani ishintsha?" Uma igeleza, futhi izogeleza, izobe sekwephuze kakhulu. I-price tag nayo ayincane manje ngizobaqonda asebeyishintshile.
Zarikov	Ngokombono wami, elinye lamaphutha amakhulu we-OM642 ukwehluleka kwama-injection. Imoto iqale ishunqe, iphelelwe amandla, kube nzima nokuyiqala ekuseni. Yiqiniso, kungase kube namapulagi akhanyayo bese wehla ngokuthuka kancane, kodwa ingxenye enkulu, ngokugijima kwe-150, lawa asevele engama-injection. Azilungiseki! Nalapha, futhi, ngifuna ukubhuka futhi ngixwayise! Yiqiniso, angazi ukuthi kunjani kwezinye izifunda zaseRussia, kodwa iMoscow igcwele amahhovisi akuthembisa izintaba zegolide ze-6500-7000. Isehlukaniso!!!! Ngokwengxenye enkulu, amahhovisi athengwa asetshenziswa. amandla aphesheya futhi ngokuwahlakaza abuyisele izinjini zamakhasimende. Iwaranti yamahhovisi anjalo ngokuvamile iyinyanga noma ezimbili. Ama-nozzles ngokwawo anesici se-piezo esingakwazi ukubuyiselwa; kusuka ku-solarium embi, impilo ye-nozzle iyancipha kakhulu. Isibonelo, uma eYurophu impilo ye-injection iyizinkulungwane ezingu-300, khona-ke sine-150. Ngokuvamile, ubuningi obungenziwa ngama-injection, uma nje isici se-piezoelectric siphila, ukushintsha ama-atomizer.
Yazi-konke	Inkinga ngale motor ukwehluleka kwephampu kawoyela. Eqinisweni, kwakukhona ama-OM 642 motors lapho benqaba ngempela ukunikeza umfutho ophansi kawoyela, kodwa njengomthetho, ama-run kuma-motor anjalo ayejulile ngaphezu kwama-200. Ngokwengxenye enkulu, inkinga ngokuhluleka kwepompo likawoyela yasungulwa ngu. izinkonzo kwesokunxele. Njengomthetho, ukuhluleka kwepompo kwenzeka ngemva kokufaka esikhundleni se-oil cooler gaskets. Kuze kube ngu-2014, i-gaskets ye-cooler yamafutha yayiyikhwalithi embi, ngakho-ke ekugijimeni kukawoyela we-120-140 kwaqala ukugeleza kusukela ekuweni kwenjini.
Isigebengu	konke kuyiqiniso
Pahel	Ingabe asikho isibuyekezo esinjalo se-ML 350, w164 272 motor? Bese nginenye yezimoto zehhovisi (2006) iminyaka engu-1,5 enama-flap abaqoqi abasikiwe. Ngicabanga ngokushintsha i-multifold noma sengivele ngiyibhincise)) Ngiyaxolisa ukuthi ayikho esihlokweni! Lapha kusuka "kumakhosi amakhulu" ngeke ulindele impendulo enengqondo))
Ikati 66	Ngezindleko zama-dampers, ngiwasusile futhi uNkulunkulu ambusise, izindleko zizokhuphuka kuphela, i-nuance kuphela. Ezinye zikhishwa ngohlelo ngama-shutter. Uma uyisuse ngendlela efanele, namathisela umthamo ngokujwayelekile, gibela futhi unganaki. Ngaphezu kwalokho, njengoba ngikuqonda, uphethiloli ungowombuso ...
UGeorge Pavel	Ku-642 094 05 80 I-gasket yepayipi yokungena inenombolo ehlukile 02 10183А/2 Ungangitsheli ukuthi ngikuqonde kanjani lokhu?

Kuyter	Kungaleyo ndlela engingakalufuni ngayo ulwazi mayelana nale moto - yonke indawo babhala ngezinkinga ku-ML ne-GL, kodwa angitholi cishe lutho ku-221 ... Ingabe aphuka kaningi noma akhononde kancane ku-inthanethi ?) Ngokombono, imoto ayilula kunezidumbu eziyi-164 ezifanayo ...
Ikati 66	Injini ye-OM 642 kuze kube ngu-2012, kungakhathaliseki ukuthi ifakwe kuphi ngenxa yokugula, iyafana ngokuphelele. 221 ngenjini ye-diesel yaseMoscow, ake sithi i-rarity. Uphethiloli owengeziwe, angazi noma kungenxa yamanani amisiwe ukuthi isigaba sebhizinisi kufanele simelele, hhayi ugandaganda. UToli ungumbungazi ovelele. Kunolwazi oluncane ngalokhu ku-inthanethi.
Kuyter	Ikuphi indawo engcono kakhulu yokuyiqhuba? Owangaphambilini wathela udizili kuphela ku-BP eminyakeni embalwa edlule ... Lona udizili wami wokuqala, ngangihlale ngithela ama-benzes ku-Gazprom / Lukoil ... ngiyazibuza futhi ukuthi yimaphi uwoyela ongcono ukuthelwa ukuze welule impilo yawo, uma nginikezwe. ukuthi ngihlela ukuyishintsha njalo nge-5 km (ngemvamisa enjalo ngingathanda okuthile okuhle ngokwentengo / ikhwalithi).
Ikati 66	Ngingasho ngokuqinisekile hhayi i-castrol, i-mobil 50-50 kuye ngokuthi uyithenga kuphi. Kunoma yikuphi, umakhalekhukhwini ungabheka iqoqo ngomgunyathi. Hhayi-ke, awekho ama-comrades okunambitheka nombala, into esemqoka ukuthi uwoyela ungaphakathi kokubekezelelana kwe-MB evunyelwe futhi yenzelwe isihlungi se-particle. Ngokuqondene nenjini, siyayisevisa futhi siyilungise futhi senze ezinye izinto eziningi ezithakazelisayo. Kungakho sabelana ngolwazi lwethu lapha, ngoba, ngeshwa, kukhona ochwepheshe abambalwa kulo mkhiqizo eningi laseRussia. Ngezindleko zokugcwalisa i-BP, ngokubona kwami, akulungile ukweqisa intengo kaphethiloli we-diesel, angiqiniseki ngekhwalithi. U-Lukoil akayena neze. Ngeluleka i-Gazprom noma i-Rosneft ukuthi ifake uphethiloli. Laba bamuva basanda kwethula ulayini omusha wokucutshungulwa kukaphethiloli, njengoba kuthenjiswe uphethiloli wabo jikelele kufanele ube sezingeni eliphezulu kakhulu. Mina ngokwami kuphela i-Gazprom, azikho izikhalo.
