I-Serie 3 enamandla kakhulu kunye nezemidlalo kuluhlu sele iqhuba. Ifihliwe ngokubanzi ngaphakathi nangaphandle, i-BMW sele iqalisile ukuvavanya enye yamatye anqabileyo ayo isithsaba: i-M3.
Kuncinci okwaziwayo malunga nomgangatho ophakathi wemoto kuluhlu lweBavara, ngakumbi malunga noyilo lwenjini kunye namandla aphezulu. Ngaba iya kugcina i-V8 emoyeni okanye iya kulandela intsingiselo ye-brand? Iibhloko zokwehlisa kunye ne-turbos ukugcina amanqanaba amandla.Sibheja kwinketho yesibini. I-M3 yexesha elizayo kufuneka, njengokuba kwenzekayo kunye nomkhuluwa wayo omdala - i-BMW M5 - ilahlekelwe ipere yeesilinda kwaye izuze iperi ye-turbos. Uxolo ngokukhutshwa...
Ndiyazi ukuba kwii-puritans zokuqhuba imidlalo, akukho nto isondela kwizithende zemoto ye-atmospheric: ukukhwela i-revs ephezulu, kwi-ballet yokukhanya ehambelana newaka, phakathi kwempendulo ye-injini kunye neemfuno zonyawo lwasekunene. Ukukhanya kwe-apotheotic kunye novuyo lwe-injini ye-atmospheric!
Andicingi (nokuba ndithandana kwaye intle kangakanani into endiyithethileyo…) ukuba ezi mpikiswano zicholwa ngabaphathi baseBrussels. I-watchword kukukhutshwa okuphantsi, ukukhutshwa okuphantsi kunye nokukhutshwa okuphantsi. Ngaba ndithe ukukhutshwa okuphantsi? Hayi?! Ke, Khuphela izinto ezikhutshwayo...
Ke into esilindeleyo kufuneka ibe kukubuyela kwimvelaphi. Siza kubuyela ekuhlaleni kunye ne-6-cylinder phantsi kwe-hood ye-M3 njengangaphambili, kodwa ngoku kunye ne-turbo yokuhamba. Ndiyakukhumbuza ukuba kuphela inguqulo eyekayo ukusebenza isetyenziswe injini ye-8-cylinder. Isiko kukusebenzisa oomatshini abaneesilinda ezintandathu. Ngaphandle kohlobo oluthile kakhulu: iBMW M3 CLS.
Kodwa akukubi konke, into yokuba ngoku sinemoto exhotyiswe nge-turbo nayo ineengenelo zayo: i-M3 elandelayo - enkosi kwi-turbo - ngokuqinisekileyo iya kuba ne-torque ekwaziyo ukuhambisa itanki. Kwaye ngaba kunokwenzeka ukuba ngenxa yobukho be-turbos, ukucoceka kokuqhuba kuya kulahleka? Isiphumo esingalunganga se "turbo-lag". Yintoni enye ngaphandle kokulibaziseka kwexesha phakathi kokucinezela i-pedal ye-accelerator kunye nempendulo ye-injini eguqulelwe kwi-accelerator.
Mhlawumbi akunjalo. Ukuvela kwee-alloys zetsimbi kwiminyaka yakutshanje kuye kwavumela iinjini zepetroli ukuba zithathe ithuba lobuchwephesha obufanayo nedemokhrasi kwiinjini zedizili kwiminyaka elishumi eyadlulayo. Njengoko unokucinga, ndithetha nge-turbos yejometri eguquguqukayo.
Njengayo yonke into ebomini, "into yonke malunga nemali", kwaye kuphela ngoku iindleko zale teknoloji ezisetyenziswe kwiinjini zepetroli ziphantsi ngokwaneleyo ukuba zikwazi ukuthengisa. Njengoko usazi, ubushushu beegesi ezibangelwa kukutsha kweenjini zepetroli - nezithi kamva zinike ubomi kwii-turbos - ziphezulu kuneenjini zedizili. Oku kuthetha ukuba ukuxhathisa ubushushu kwe-turbos kwiinjini zepetroli kufuneka kube phezulu. Oku, ngokuqinisekileyo, kubandakanya iindleko zokusetyenziswa kweealloyi zetsimbi "ezihloniphekileyo". Akumangalisi ukuba imoto yokuqala yepetroli ukusebenzisa le teknoloji yayiyiPorsche 911 Turbo (997) efikelelekayo.
Ngokusisiseko, inzuzo enkulu yezi turbos - ezo zinejiyometri eguquguqukayo - kukuvumela uluhlu olukhulu lokusebenza kwesixhobo kulo lonke uluhlu lokujikeleza, ukuhluka kwee-blades ze-iturbine njengomsebenzi wokuhamba kwegesi, ngaloo ndlela kufihla ukungena ekusebenzeni ( ngequbuliso. ) ye-turbo, sonke esiyaziyo kwiimoto ze-80s, ekuqaleni kwe-90 kunye nokuvumela ukukhawuleza "ukuzaliswa okufanayo, okubangelwa ukuphendula ngokukhawuleza kwizicelo zonyawo oluchanekileyo.
Ukuba sinxulumanisa ii-turbos ezimbini kwibhloko, nokuba ngcono: Enkulu kuluhlu lwe-rev ephezulu kwaye ifuna ukuhamba kwerhasi eninzi ukujika; kunye nenye, encinci, eqala ukusebenza kwangoko kwaye idinga ukuhamba okuncinci ukusebenza.
Ke sinenjini engqukuva ekhoyo, enoluhlu olubanzi lwee-rpm ezisebenzisekayo ezincediswa yitorque enkulu. Kwaye… ibukhali kancinci kune-atmosfere kwaye imtyibilizi ngokulinganayo kune-turbocharged eqhelekileyo, enika yonke into okanye akukho nto.
Bukela le vidiyo:
Kodwa sibuyele kwi-M3 yethu… njengoko benditshilo sikholelwa ukuba isisombululo iya kuba yi-bi-turbo injini.
Ngokubhekiselele kwezinye izisombululo eziza kwamkelwa kwimodeli entsha, ziqikelelwa ngakumbi: ivili elingasemva; ukumiswa okusebenzayo; umahluko ngasemva koomatshini; I-8-speed dual-clutch gearbox, njl.
Kodwa eyona nto ibalulekileyo sisimbuku sawo onke amalungu. Kwaye kwabengezela iBMW. Ikwazile ukuboleka indalo yayo ubuchule bokuqhuba kunye nokungatshoni kwabantu kwezinye iimoto, ezinokuthi zibe namanani aphezulu amandla kunye ne-chassis ephuhliswe ngakumbi, kodwa engayazi indlela yokunxibelelana nomqhubi.
Kwaye kulo mmandla apho iBMW yenze umahluko. Kukweli candelo apho sinethemba lokuba iM3 entsha iza kugqama. Ngo-2014 siza kuba nayo impendulo.
