BMW 3 mndandanda (E46) - mphamvu ndi zofooka za chitsanzo

Imayendetsa bwino ndipo sikusangalatsa kuyendetsa kuposa magalimoto ambiri amasewera. Izi zati, zikuwonekabe zosangalatsa (makamaka zakuda kapena kaboni graphite) ndipo zimamveka ngati zolusa kwambiri pamatembenuzidwe a silinda asanu ndi limodzi. BMW 3 Series E46 ndi Bavarian weniweni yemwe mungayambe kukondana naye pambuyo pa makilomita angapo oyambirira. Komabe, chikondi ichi, chifukwa cha khalidwe lokopa la galimoto, nthawi zambiri zimakhala zodula kwambiri.

Series 3 yolembedwa ndi chizindikiro E46 idayamba kugulitsidwa mu 1998. Pasanathe chaka chimodzi, zoperekazo zidawonjezeredwanso ndi ngolo yamasiteshoni ndi coupe, ndipo mu 2000 chosinthira chowoneka bwino chidalowanso pamndandanda wamitengo. Mu 2001, mlendo adawonekera muzopereka zotchedwa Compact - mawonekedwe ofupikitsa a chitsanzo, opita kwa achinyamata ndi achangu. Panthawi yomweyi, galimotoyo inakhalanso ndi zamakono zamakono - osati khalidwe lamkati lamkati lokha likuyenda bwino, koma zida zatsopano zamagetsi zinayambitsidwa, zomwe zilipo kale zinasinthidwa ndipo kunja kunasinthidwa - "troika" inatenga umbombo ndi kalembedwe ka Bavaria. . Mu mawonekedwe awa, galimoto inatha mpaka mapeto a kupanga, ndiye mpaka 2005, pamene wolowa m'malo anaonekera - chitsanzo E90.

BMW 3 Series nthawi zonse imadzutsa malingaliro. Izi zinali zina chifukwa chakuti checkerboard pa hood anali atavala, ndipo mwina chifukwa cha maganizo abwino a magalimoto Bavarian. BMW, monga m'modzi mwa opanga ochepa, amalimbikirabe pamayendedwe apamwamba, omwe amakopa mafani ambiri. Kuyendetsa magudumu kumbuyo kumapangitsa kuyendetsa galimoto kukhala kosangalatsa kwambiri, makamaka m'nyengo yozizira kwambiri.

BMW 3 Series E46 imagwirizana bwino ndi nzeru zamtundu - kuyimitsidwa kwamasewera, konyowa kumakupatsirani kumva bwino kwa msewu ndikukupangitsani kumwetulira nthawi iliyonse. Tsoka ilo, masewera agalimoto nthawi zambiri amayambitsa kukwera kwamphamvu komanso kwamasewera, komwe, mwatsoka, kumakhudza kulimba kwa zinthu zoyimitsidwa (makamaka zenizeni zaku Poland). Magalimoto ogwiritsidwa ntchito kwambiri, omwe mwatsoka sakusowa pamsika wachiwiri, amakhala okwera mtengo kwambiri kuti azithamanga pakapita nthawi. Ngakhale 3 Series imatengedwa odalirika ndi cholimba kwambiri galimoto, ilinso downsides ake. Mmodzi wa iwo ndi kufala ndi kuyimitsidwa - m'magalimoto "ozunzidwa" kwambiri, phokoso losokoneza limamveka kuchokera kumalo osiyanitsa (mwamwayi, kutulutsa kumakhala kosowa), ndipo kutsogolo kuli zikhomo zosasinthika. manja. M'magalimoto a nthawi yoyamba yopanga, kuyimitsidwa kumbuyo kunalibe zomata zomangika.

Palinso zovuta ku mayunitsi amafuta omveka bwino, omwe nthawi zambiri amakhala odalirika komanso osayambitsa mavuto. Chachikulu cha iwo ndi dongosolo kuzirala, amene analephera (pampu, chotenthetsera, kutayikira kwa thanki ndi mapaipi) kupanga mu mzere injini zisanu yamphamvu "zodzaza" pansi pa nyumba tcheru kwambiri kutenthedwa (yamphamvu mutu gasket).

Injini za dizilo nthawi zambiri zimagwira ntchito popanda mavuto, koma monga injini zonse zamakono za dizilo, zimakhalanso ndi vuto ndi dongosolo lamagetsi (pampu, majekeseni, mita yotaya). Ma turbocharger amaonedwa kuti ndi olimba kwambiri, ndipo ma dizilo amakono otengera Common Rail system (2.0 D 150 hp, 3.0 D 204 hp) amasiyanitsidwa ndi magwiridwe antchito komanso kutsika kwa dizilo.

BMW 3 E46 ndi galimoto yopangidwa bwino yomwe imayendetsa bwino kwambiri. Zimapereka mwayi woyendetsa bwino kwambiri, chitonthozo chamsewu (zida zolemera), koma mu mtundu wa sedan siwoyenera pagalimoto yayikulu yabanja (thunthu laling'ono, mkati mocheperako, makamaka kumbuyo). Sitima yapamtunda ndiyothandiza pang'ono, koma pakadali malo ochepa kumpando wakumbuyo. Komanso, 3 E46 mndandanda si galimoto yotsika mtengo kwambiri kusamalira. Mapangidwe apamwamba komanso apamwamba ophatikizidwa ndi zamagetsi amatanthauza kuti si malo onse ogwirira ntchito omwe angakwanitse kukonza magalimoto mwaukadaulo. Ndipo sera E46 imafunadi kuti isangalale ndi kudalirika kwake. Zigawo zopangira zida zoyambirira ndizokwera mtengo, ndipo zosinthidwa nthawi zambiri zimakhala zotsika mtengo. Ma dizilo atatu-lita amawotcha mafuta pang'ono a dizilo, koma mtengo wokonza ndi kukonzanso zotheka ndizokwera kwambiri. Kumbali ina, mayunitsi a petulo amayambitsa zovuta zochepa (timing chain drive), koma amakhala ndi chidwi chachikulu chamafuta (mitundu ya silinda sikisi). Komabe, mafani a mawilo anayi okhala ndi cholembera choyera ndi buluu pa hood sakulepheretsani - sikovuta kugwa m'chikondi ndi galimoto iyi.
