I-MultiAir yokuhlola inciphisa ukusetshenziswa kukaphethiloli ngo-25%

I-Fiat yethule ubuchwepheshe obuthi, ngokusebenzisa i-valve ekhethiwe ku-cylinder ngayinye, kunciphise ukusetshenziswa kukaphethiloli nokukhishwa okungafika ku-25%. Ukuqala kwayo kufanele kulonyaka e-Alfa Mito.

Lobu buchwepheshe bususa i-camshaft yokudla ejwayelekile ezimotweni ezinama-valve amane isilinda ngasinye. Esikhundleni sayo kufakwa i-electro-hydraulic valve actuator.

Ukusetshenziswa okungaphansi kwama-25% namandla angaphezulu ngo-10%

Inzuzo ukuthi ama-valve wokudonsa aqhutshwa ngaphandle kwe-crankshaft. Kuhlelo lweMultiAir, ama-valve okudonsa angavulwa futhi avale nganoma yisiphi isikhathi. Ngakho-ke, ukugcwaliswa kwesilinda kungashintshwa nganoma yisiphi isikhathi kumthwalo weyunithi. Lokhu kuvumela injini ukuthi isebenze kahle kakhulu kunoma yisiphi isimo.

Ngaphezu kokwehliswa okukhulu kokusetshenziswa kukaphethiloli kanye nokukhipha umoya, iFiat iphinde ithembise ukwenyuka kwetorque ngo-15% ebangeni eliphansi le-rpm, kanye nokuphendula kwenjini esheshayo ikakhulukazi. Ngokusho kwenkampani, ukwanda komthamo kufinyelela ku-10%. Ngaphezu kwalokho, esimweni senjini ebandayo, ukukhishwa kwe-nitrous oxide kufanele kuncishiswe kuze kufike ku-60%, futhi ikakhulukazi i-carbon monoxide eyingozi ngo-40%.

IFiat ihlose ukusebenzisa ubuchwepheshe beMultiAir kuzinjini zombili ezihlosiwe futhi ezinama-turbocharged. Ngaphezu kwalokho, izinjini zikadizili nazo kufanele zizuze kulokhu.

Ama-MultiAir debuts ku-Alfa Romeo Mito

I-Alfa Romeo Mito entsha izofakelwa ubuchwepheshe beMultiAir maphakathi nonyaka. Izotholakala nenjini kaphethiloli engu-1,4 litre ngokwemvelo efiselekayo kanye ne-turbocharged version. Ngaphezu kwalokho, iFiat isimemezele injini entsha sha ka-900cc yamasilinda amabili kaphethiloli. Bona ngobuchwepheshe beMultiAir.

Injini izokwenzelwa ukuthi isebenzise uphethiloli kanye negesi yemvelo (CNG), futhi izophinde ikhiqizwe ngezinhlobo zomkhathi kanye ne-turbo. Ngokusho kokukhathazeka, ukukhishwa kwayo kwe-CO2 kuzoba ngaphansi kwama-gramu angama-80 ngekhilomitha.

Izinjini zikadizili nazo zizofakelwa uhlelo lweMultiAir.

IFiat ihlela ukusebenzisa ubuchwepheshe beMultiAir ezinjinini zayo zikadizili ngokuzayo. Zizophinda futhi zinciphise kakhulu ukungcola okungalawulwa ngokulawula ngempumelelo kanye nokwenza kabusha isihlungi se-particulate.
