BMW N46B18 injini
Inguqulo encane kakhulu yomugqa we-N46 wamayunithi wamandla - i-N46B18, yadalwa ngesisekelo se-N46B20 futhi yakhiqizwa kusukela ngo-2004, futhi kuphela izimoto ze-BMW E46 316. Maphakathi no-2006, mayelana nokwethulwa kwe-BMW E90, wonke amamodeli we-E46 asuswe ngokuphelele emgqeni womhlangano, kodwa le njini ayizange izuze ukusatshalaliswa okukhulu.
I-N46B18 ekuqaleni yayihloselwe ukuvala indawo eyandulelayo, i-N42B18, futhi yathola i-crankshaft eguquliwe, ama-balance shafts ashintshiwe nezinduku zokuxhuma, kanye nezihluke ngokuphelele: ikhava yekhanda yesilinda kanye ne-tensioner chain tensioner. I-N46B18 ifakwe (entsha): intake intake, generator kanye nama-spark plugs.
Ngokungafani ne-N46 evamile, ukuhluka kwayo okungu-1.8-litre kwakune: crankshaft ethole i-stroke emfishane (81 mm); ama-piston anesilinganiso sokucindezela esingu-10.2; umqoqi ojwayelekile - ngaphandle kwe-DISA. I-Valvetronic ihlanganiswe ohlelweni lwe-Bosch ME 9.2.
Isikhungo samandla se-N46B18, njengenguqulo yaso engu-2-litre, sinenani lamamodeli ahlobene adalwe cishe kusisekelo esifanayo.
Ngo-2011, i-N46B18, njengamanye uphethiloli we-line "omane" we-BMW, yathathelwa indawo injini entsha ye-turbocharged N13B16, ekhiqizwa ngokuguqulwa okuhlukahlukene kuze kube namuhla.

Ukuthembeka kanye nokubi kwe-N46B18
Плюсы
- Ukudla okuningi
- Khipha i-camshaft
- Shintsha amandla
Umthengi:
- Ukwenyuka kokusetshenziswa kukawoyela nokuvuza
- Umsindo wenjini, ukudlidliza
- Izinkinga nge-Valvetronic, iphampu kawoyela, i-KVKG nephampu yevacuum
Isizathu esiyinhloko ukubukeka ukusha uwoyela N46B18, njengoba injini 42 - ukusetshenziswa uwoyela ongaphakeme motor. Inkinga ingase futhi ibe ngenxa yokuhluleka kwama-valve seal.
Lokhu kwenzeka ikakhulukazi ngemva mileage 50-100 ayizinkulungwane km. Amafutha anganconywa umenzi angaholela ezinkingeni ezengeziwe. Isibonelo, nge-Valvetronic efanayo, iphampu yamafutha, i-valve ye-ventilation ye-crankcase njalonjalo. Kulesi simo, akufanele neze ukonga ekunakekeleni.
Futhi, ngemva kwebanga elingamakhilomitha ayizinkulungwane ezingu-50, i-cylinder head gasket kanye nepompo ye-vacuum cishe kuzodingeka ishintshwe.
Izimbangela zokudlidliza nomsindo wenjini ongewona owemvelo ngokuvamile uhlala ku-tensioner yesikhathi noma iketango eliluliwe. Ngemva mileage 100-150 ayizinkulungwane km, izinkinga ezinjalo azivamile neze.
Ukuze unciphise amathuba okuba nezinkinga zenjini, kungakuhle ukuthi ushintshe uwoyela ngesikhathi, noma kaningi, okumele kube okwangempela futhi kunconywe umenzi. Ngaphezu kwalokho, kubalulekile ukusebenzisa uphethiloli omuhle futhi unakekele ngesikhathi esifanele.
Amandla okushuna
Njengezinye izinjini ezivuthayo zangaphakathi ezingama-4-cylinder ezinevolumu encane, i-N46B18 ilungele ukushintshaniswa, kodwa ayifaneleki ngokuphelele ukushunwa futhi okuwukuphela kwendlela eyanele yokwandisa amandla esimweni sayo kungaba ukushuna kwe-chip. Ngokunokwenzeka, isitudiyo sokulungisa sizofaka isihlungi esingamelani ne-zero, esizolethwa kubhampa wangaphambili, sisike i-catalyst futhi sikhanyise kabusha uhlelo ngokuphelele. Konke lokhu kuzokuvumela ukuthi ukhuphule amandla futhi uthole +10 hp. Ukuze uthole into enkulu, kuzodingeka ufake injini engu-6-cylinder.
