Izinjini ze-M30 nezinguqulo zafakwa ku-BMW 5-7 uchungechunge lwezimoto ezizukulwaneni eziyi-1-2 kusukela ngo-1982 kuya ku-1992.

Izinguqulo ezithuthukisiwe (isibonelo, i-M30B28LE, M30B33LE) zifakwe ezimotweni ze-BMW zezizukulwane ezingu-5-7 zeminyaka yokuqala yokukhiqiza, futhi izinjini ezivuthayo zangaphakathi ezithuthukisiwe ezifana ne-M30B33LE zingatholakala kuphela ezimotweni zezizukulwane ezingu-6-7.

Ukuguqulwa

Injini ye-in-line ye-BMW M30 yathola izinguqulo ezihlukile kumthamo we-cylinder. Ngokwemvelo, ngokwesakhiwo bahluke kancane komunye nomunye futhi, ngaphandle kwamandla ne-torque, abanawo umehluko omkhulu.

Izinguqulo:

1. I-M30B25 iyinjini encane kunazo zonke ene-displacement engu-2.5 amalitha. Yakhiqizwa ukukhathazeka kusukela ngo-1968 futhi yasetshenziswa kusukela ngo-1968 kuya ku-1975 ezimotweni ze-BMW 5 Series. Amandla ayengu-145-150 hp. (ifinyelelwe ku-4000 rpm).
2. M30B28 – injini umthamo 2.8 amalitha namandla 165-170 hp. Ingatholakala kuma-sedan angu-5 no-7.
3. I-M30B30 - injini yomlilo yangaphakathi enamandla angama-cylinder angu-3 amalitha namandla angu-184-198 hp. ngo-4000 rpm. Le nguqulo yafakwa ku-BMW 5 no-7 series sedans kusukela ngo-1968 kuya ku-1971.
4. I-M30B33 – inguqulo enamandla angu-3.23 litres, amandla angu-185-220 hp ne-torque engu-310 Nm ku-4000 rpm. Iyunithi yafakwa ezimotweni zeBMW 635, 735, 535, L6, L7 kusukela ngo-1982 kuya ku-1988.
5. I-M30B35 iyimodeli enevolumu enkulu kunazo zonke kulayini - amalitha angu-3.43. Amandla angu-211 hp ifinyelele ku-4000 rpm, i-torque - 305 Nm. Kufakwe kumamodeli angu-635, 735, 535 kusukela ngo-1988 kuya ku-1993. Inguqulo iphinde yathola ukuguqulwa okuhlukahlukene. Ikakhulukazi, iyunithi amandla M30B35LE ithuthukiswe amandla afinyelela ku-220 hp, futhi torque yayo yafinyelela 375 Nm at 4000 rpm. Okunye ukuguqulwa - i-M30B35MAE - ifakwe i-supercharger-turbine futhi ithuthukisa amandla angu-252 hp, futhi i-torque yayo ephezulu idluliselwa ngesivinini esiphansi - 2200 rpm, okuqinisekisa ukusheshisa okusheshayo.

Incazelo motors

Izinjini ze-M30 ezinamavolumu ahlukene zitholakala ezimotweni zochungechunge lwe-5, 6 no-7. Kungakhathaliseki umthamo, izinjini zibhekwa njengokwethenjelwa futhi ziqinile. Impilo ende yenjini evuthayo yangaphakathi iqinisekiswa ngamandla ayo aphezulu, ngoba izinjini ezinamandla azilayishwa kakhulu ngesikhathi sokushayela kwedolobha okusesilinganisweni, yingakho zihlala isikhathi eside. Ukuguqulwa okumbalwa okuphumelelayo kuphela ngevolumu engama-3.5 amalitha. Kuvele ukuthi idla amandla futhi iqinile uma iqhathaniswa nezinye izinguqulo.

Okuthandwa kakhulu ochungechungeni injini ye-M30B30 - yafakwa kuzo zonke izimoto ezinenkomba engu-70 no-80i kuma-30-30s. Njengabanduleli bayo i-B25 ne-B28, le njini inamasilinda angu-6 ahlelwe ngokulandelana. Iyunithi isekelwe ku-cast iron block enezisilinda ezinobubanzi obungu-89 mm. Kukhona i-camshaft eyodwa kuphela ekhanda lesilinda (uhlelo lwe-SOHC), futhi azikho izinxephezelo ze-hydraulic, ngakho emva kwe-10 km. ukulungiswa kwe-valve kuyodingeka.

Indlela yesikhathi isebenzisa iketanga lempilo ende; isistimu yamandla ingaba umjovo noma i-carburetor. Lesi sakamuva sasetshenziswa kwaze kwaba ngu-1979, futhi ngemva kwalokho kwasetshenziswa ama-injection kuphela ukuhlinzeka ngengxube kaphethiloli emoyeni kumasilinda. Okusho ukuthi, izinjini zokujova zisabalele kakhulu.

Phakathi naso sonke isikhathi sokukhiqiza, izinjini ze-M30B30 (lokhu kusebenza nasezinjinini ezinamanye amavolumu) zishintshiwe, ngakho awekho amandla ajwayelekile kanye ne-torque kubo. Ngokwesibonelo, injini ye-carburetor eyakhululwa ngo-1971 yathola isilinganiso sokucindezela 9, futhi amandla ayo afinyelela ku-180 hp. Ngawo lowo nyaka, baphinde bakhipha injini yomjovo enesilinganiso sokucindezela esingu-9.5 namandla angu-200 hp, atholakala ngesivinini esiphansi - 5500 rpm.

Kamuva, ngo-1971, kwasetshenziswa ezinye carburetors, okwashintsha izici zobuchwepheshe injini - amandla ayo anda ku-184 hp. Ngesikhathi esifanayo, izinhlelo zokujova zashintshwa, ezithinta amandla. Bathola isilinganiso sokucindezela esingu-9.2, amandla - 197 hp. ngo-5800 rpm. Lona kanye iyunithi eyafakwa 730 BMW 32i E1986.

Kwakuyi-M30B30 eyaba "i-springboard" yokukhiqizwa kwezinjini ze-M30B33 ne-M30B35 ezinamavolumu angu-3.2 no-3.5 amalitha, ngokulandelana. Ngo-1994, izinjini ze-M30B30 zanqanyulwa, kwashintshwa amayunithi amasha we-M60B30.

I-BMW M30B33 kanye ne-M30B35

Izinjini ezinamavolumu angu-3.3 no-3.5 amalitha ziyizinguqulo eziyisithukuthezi ze-M30B30 - zine-cylinder enkulu (92 mm) kanye ne-piston stroke engu-86 mm (ku-B30 80 mm). Ikhanda le-cylinder liphinde lathola i-camshaft eyodwa, ama-valve angu-12; Azikho izinxephezelo ze-hydraulic, ngakho-ke ngemuva kwamakhilomitha ayizinkulungwane eziyi-10 ukucaciswa kwamavalvu okudingeka kulungiswe. Phela, ochwepheshe abaningi baguqule i-M30B30 ibe yi-M30B35 ngokusebenzisa izindlela ezilula. Ukuze wenze lokhu, i-cylinder block yayinesithukuthezi, amanye ama-piston kanye nezinduku zokuxhuma zafakwa. Lena inketho elula kakhulu yokulungisa injini evuthayo yangaphakathi, ekuvumela ukuthi uthole ukwanda kwe-30-40 hp. Uma ufaka i-camshaft ye-Schrick 284/280 ethuthukisiwe futhi wenza ukuphuma okugeleza okuqondile, faka i-firmware elungile, khona-ke amandla anganyuswa abe ngu-50-60 hp.

Kwakukhona izinguqulo eziningana zale njini - ezinye zinesilinganiso sokucindezela esingu-8 futhi zifakwe ama-catalysts, amandla akhulayo afika ku-185 hp; abanye bathole ukucindezelwa kwe-10, kodwa babengenawo ama-catalysts, athuthukiswe i-218 hp. Kukhona futhi injini yokucindezela engu-9 ene-211 hp, ngakho-ke awekho amandla ajwayelekile kanye nesilinganiso se-torque.

E9 BMW M30b30

Amandla okushuna we-M30B35 abanzi - kukhona izingxenye zokulungisa ezithengiswayo ezikuvumela ukuthi uvule amandla enjini yangaphakathi yomlilo. Izinketho zokuhlela zihlukile: ungafaka i-crankshaft nge-piston stroke engu-98 m, uthwale amasilinda ukuze ukhulise ivolumu ibe amalitha angu-4-4.2, ufake ama-pistons akhiwe. Lokhu kuzokwengeza amandla, kodwa izindleko zomsebenzi zizoba phezulu.

Ungakwazi futhi ukuthenga ikhithi ye-turbo yaseShayina enamandla angu-0.8-1 ibha - ngosizo lwayo ungakwazi ukwandisa amandla ku-400 hp, nakuba kuphela amakhilomitha ayizinkulungwane ezingu-2-3, ngoba i-turbo kits ayihlali isikhathi eside.

Izinkinga zenjini ye-M30

Njengazo zonke izinjini, i-M30 izinjini zinezinkinga ezithile, nakuba kungekho "izifo" ezimbi noma ukwehluleka kobuchwepheshe okuvamile kochungechunge. Phakathi nempilo ende yesevisi yezinjini, kwakungenzeka ukuhlonza amaphutha alandelayo:

1. Ukushisa ngokweqile. Inkinga yenzeka ezinjinini eziningi zakwaBMW ezivuthayo zangaphakathi ezinomthamo ongu-3.5 amalitha. Uma ubona ukwanda kwezinga lokushisa, kungcono ukuhlola ngokushesha isimo sesistimu yokupholisa, ngaphandle kwalokho ikhanda le-cylinder lizoqala ukuvuza ngokushesha okukhulu. Ezimweni ezingu-90%, isizathu sokwanda kwezinga lokushisa silele ohlelweni lokupholisa - i-radiator (ingase ibe ingcolile nje), ipompo, i-thermostat. Kungenzeka ukuthi amaphakethe omoya angase akheke ohlelweni ngemva kokufaka i-antifreeze.
2. Imifantu kubhlokhi yesilinda akha eduze kwemicu yebhawudi. Inkinga enzima kakhulu ngezinjini ze-M. Izimpawu ezijwayelekile: ukwehla kwezinga le-antifreeze, ukwakheka kwe-emulsion emafutheni. Ngokuvamile ukuqhekeka kwakha ngenxa yokuthi inkosi ayizange isuse i-lubricant emithonjeni enezintambo lapho ihlanganisa injini. Le nkinga ixazululwa ngokufaka i-cylinder block; ayivamisile ukulungiswa.

Kuyafaneleka futhi ukucabangela ukuthi zonke izinjini ze-M30 kusukela maphakathi no-2018 zindala - azizange zikhiqizwe isikhathi eside, futhi impilo yabo yenkonzo icishe iphele. Ngakho-ke, nakanjani bayobhekana nezinkinga ezihlobene nokuguga kwemvelo. Ukuphazamiseka ekusebenzeni kwendlela yokusabalalisa igesi, ama-valve (ayaguga) kanye ne-crankshaft nama-bushings kungenzeka.

Ukuthembeka kanye nensiza

Izinjini ze-M30 zingamayunithi apholile futhi athembekile anempilo ende yesevisi. Izimoto ezisekelwe kuzo zingakwazi "ukugijima" amakhilomitha ayizinkulungwane ezingu-500 nangaphezulu. Njengamanje, imigwaqo yaseRussia igcwele izimoto ezinalezi zinjini ezivuthayo zangaphakathi, ezisasebenza.

Kuyafaneleka futhi ukugqamisa ulwazi lokuklama nezinkinga zezinjini ze-M30, ngakho-ke ukususa noma ukulungisa izingxenye kulula, kodwa izinkinga zivame ukuvela ngokuthola izingxenye ezidingekayo. Ngakho-ke, ukulungisa injini ye-M30 kungase kuthathe isikhathi eside.

Ingabe kufanele uthenge?

Namuhla lawa mayunithi athengiswa kumasayithi akhethekile. Isibonelo, injini yenkontileka ka-30 M30B1991 ingathengwa ngama-ruble angu-45000. Ngokusho umthengisi, "wagijima" km 190000 kuphela, okuyinto akwanele kule injini, uma kubhekwa ukuthi ukuphila kwayo esiwusizo ifinyelela 500+ amakhilomitha ayizinkulungwane.

I-M30B35 ingatholakala ngama-ruble angu-30000 ngaphandle kokunamathiselwe.

Intengo yokugcina incike esimweni, imayela, ubukhona noma ukungabikho kokunamathiselwe.

Naphezu kokuthembeka kanye nomklamo ophumelele ngobuchwepheshe, zonke izinjini ze-M30 azinconywa ukuthi zithengwe namuhla. Izinsiza zabo zizophela, ngakho abakwazi ukuqinisekisa ukusebenza okujwayelekile okungaphazanyiswa ngenxa yokuguga kwemvelo.
