Mawonekedwe a TwinTurbo turbocharging system

Vuto lalikulu pogwiritsira ntchito turbocharger ndi inertia ya dongosolo kapena zochitika zomwe zimatchedwa "turbo lag" (nthawi yapakati pa kuwonjezeka kwa liwiro la injini ndi kuwonjezeka kwenikweni kwa mphamvu). Kuti athetse, chiwembu chinapangidwa pogwiritsa ntchito ma turbocharger awiri, omwe amatchedwa TwinTurbo. Tekinolojeyi imadziwikanso ndi opanga ena monga BiTurbo, koma kusiyana kwa mapangidwe kumangokhala mu dzina lamalonda.

Mawonekedwe a Twin Turbo

Makina apawiri kompresa amapezeka pamainjini a dizilo ndi petulo. Komabe, chomalizacho chimafuna kugwiritsa ntchito mafuta apamwamba kwambiri omwe ali ndi chiwerengero chachikulu cha octane, chomwe chimachepetsa mwayi wa detonation (chodabwitsa chomwe chimapezeka muzitsulo za injini, kuwononga gulu la silinda-pistoni).

Kuphatikiza pa ntchito yake yayikulu yochepetsera nthawi ya turbo lag, dongosolo la Twin Turbo limalola kuti mphamvu zambiri zitengedwe kuchokera ku injini yagalimoto, zimachepetsa kugwiritsa ntchito mafuta ndikusunga torque yapamwamba pamitundu yambiri. Izi zimatheka pogwiritsa ntchito njira zosiyanasiyana zolumikizirana ndi compressor.

Mitundu ya Turbocharging yokhala ndi ma turbocharger awiri

Kutengera momwe ma turbocharger amalumikizidwira, pali masanjidwe atatu oyambira a TwinTurbo system:

• kufanana;
• zogwirizana;
• adaponda.

Kulumikiza ma turbines molumikizana

Amapereka kulumikizana kwa ma turbocharger awiri ofanana omwe amagwira ntchito limodzi (nthawi yomweyo). Chofunikira pamapangidwewo ndikuti ma turbine ang'onoang'ono awiri amakhala ndi inertia yocheperako kuposa yayikulu.

Asanalowe m'masilinda, mpweya womwe umapopedwa ndi ma turbocharger onse umalowa m'malo ochulukirapo, pomwe umasakanikirana ndi mafuta ndikugawidwa kuzipinda zoyaka. Chiwembu ichi nthawi zambiri chimagwiritsidwa ntchito pa injini za dizilo.

Kulumikizana kwa seri

Dongosolo lofananirako limapereka kukhazikitsa ma turbines awiri ofanana. Mmodzi amagwira ntchito mosalekeza, ndipo chachiwiri chikugwirizana ndi kuwonjezeka kwa liwiro la injini, kuwonjezeka kwa katundu, kapena mitundu ina yapadera. Kusintha kuchokera kumayendedwe amodzi kupita ku ena kumachitika kudzera mu valavu yoyendetsedwa ndi injini yagalimoto ECU.

Dongosololi cholinga chake ndichochotsa turbo lag ndikukwaniritsa zowongolera zamagalimoto zamagalimoto. Machitidwe a TripleTurbo amagwira ntchito mofananamo.

Gawo lothandizira

Kuchulukitsa kwa magawo awiri kumakhala ndi ma turbocharger amitundu yosiyanasiyana, omwe amaikidwa motsatizana ndikulumikizidwa ndi madoko olowera ndi kutulutsa. Zotsirizirazi zimakhala ndi mavavu odutsa omwe amawongolera kutuluka kwa mpweya ndi mpweya wotulutsa mpweya. Njirayi ili ndi njira zitatu zogwirira ntchito:

• Mavavu amatsekedwa pa low rpm. Mpweya wotulutsa mpweya umadutsa mumagetsi onse awiri. Chifukwa mphamvu ya gasi ndiyotsika, ma turbine impellers akulu sazungulira movutikira. Mpweya umayenda m'magawo onse awiri a kompresa zomwe zimapangitsa kuti pakhale kupanikizika kwambiri.
• Pamene RPM ikuwonjezeka, valve yotulutsa mpweya imayamba kutseguka, yomwe imayendetsa turbine yaikulu. Compressor wamkulu amapondereza mpweya, pambuyo pake amatumizidwa ku gudumu laling'ono, kumene kuponderezedwa kwina kumagwiritsidwa ntchito.
• Pamene injini ikuyenda mofulumira, ma valve onsewa amatseguka, omwe amatsogolera kutuluka kwa mpweya wotulutsa mpweya wopita ku turbine yaikulu, mpweya umadutsa mu compressor yaikulu ndipo nthawi yomweyo umatumizidwa ku ma silinda a injini.

Mtundu wa stepped umagwiritsidwa ntchito kwambiri pamagalimoto a dizilo.

Twin Turbo zabwino ndi zoyipa

Pakadali pano, TwinTurbo imayikidwa makamaka pamagalimoto ochita bwino kwambiri. Kugwiritsiridwa ntchito kwa dongosololi kumapereka ubwino monga kutumiza kwa torque pazipita maulendo osiyanasiyana a injini. Kuphatikiza apo, chifukwa cha turbocharger yapawiri, yokhala ndi gawo laling'ono logwira ntchito lamagetsi, kuwonjezereka kwa mphamvu kumatheka, zomwe zimapangitsa kuti zikhale zotsika mtengo kuposa "zofuna".

Zoyipa zazikulu za BiTurbo ndizokwera mtengo, chifukwa chazovuta za chipangizocho. Monga momwe zimakhalira ndi ma turbine apamwamba, ma twin turbocharger amafunikira kuwongolera mofatsa, mafuta abwinoko komanso kusintha kwamafuta munthawi yake.
