IMultiAir
Izinjini zeMultiAir zisebenzisa i-electro-hydraulic system ezilawula ngokuzimela ama-valve wokudla wesilinda ngayinye. Ngokuya ngesimo esisheshayo semoto, uhlelo luzivumelanisa ngokuzenzakalela nenye yezindlela eziyisihlanu eziyinhloko zesikhathi se-valve esiguqukayo nokuphakama kwe-valve okuguquguqukayo. Kodwa-ke, umgomo kuma-MultiAir motors uvumela inani elingenamkhawulo lokuhlanganiswa okuguqukayo kokulawulwa kwe-valve control ngokuya ngesifo sohlangothi nangesikhathi.
Uhlelo luthakazelisa ngokwengeziwe, futhi luguqula izinguquko, ngoba ngokwanda ngasikhathi sinye kwamandla we-injini ne-torque, kunciphisa nokusetshenziswa kukaphethiloli ngakho-ke kukhishwa umoya. Umqondo walesi sixazululo ubonakala ulungele ukuthambekela kwamanje okuya ngokuya ngokuya ngokuhlanza namandla amancane. IFiat Powertrain Technologies, umnyango osungule futhi wanika ilungelo lobunikazi bohlelo, uthi uma kuqhathaniswa nenjini evamile yomlilo osayizi ofanayo, iMultiAir ingakhipha u-10% wamandla athe xaxa, i-torque engu-15% ngaphezulu futhi yehlise ukusetshenziswa kuze kufike ku-10%. Ngakho-ke, ukukhiqizwa kokukhishwa kwe-CO kuzoncishiswa ngokufanele.2 10%, udaba lwezinhlayiya olufinyelela ku-40% no-NOx ngo-60% omangalisayo.
I-Multiair inciphisa ukuncika kokuhamba kwe-valve endaweni eqondile yekhamera, ngakho inikeza izinzuzo ezimbalwa phezu kwamavalvu aguquguqukayo oxhumano lwemishini oluvamile. Isisekelo sohlelo yigumbi le-hydraulic, elitholakala phakathi kwekhamera yokulawula kanye ne-valve yokumunca ehambisanayo. Ngokushintshwa kokucindezela okulawulwayo kuleli gumbi, kungenzeka ukufeza ukuvulwa kamuva noma, ngokuphambene, ukuvala kwangaphambili kwe-valve yokungena, kanye nokuvulwa kwama-valve okungena ngesikhathi sokukhipha isisu, okunikeza ukuphindaphinda kwangaphakathi kwamagesi okukhipha umoya. . Enye inzuzo ye-Multiair system ukuthi, njengezinjini ze-BMW Valvetronic, ayidingi i-throttle valve. Lokhu kunciphisa kakhulu ukulahlekelwa kokumpompa, okubonakala emazingeni okugeleza aphansi, ikakhulukazi ekulayisheni okuphansi kwenjini.
