Cav tsim 5.7 Hemi - dab tsi tsim kev daws teeb meem?

 Lub cav 5.7 Hemi tau raug kho dua tshiab los ntawm hauv av nrog lub tsho sib sib zog nqus cam khwb cia hlau lub tog raj kheej thaiv thiab 90 ° lub tog raj kheej phab ntsa. Cov qauv ua ntej xyoo 2008 tau dav dua 1,50/1,50/3/0mm rings, thaum 2009 qauv featured 1,20/1,50/3,0mm pob.

Lub camshaft kuj tau tsim los ntawm qhov siab dua kom txo qhov ntev ntawm cov pushrods. Vim li no, lub sij hawm saw txuas ntev dua thiab nyob nruab nrab ntawm lub tog raj kheej lub tog raj kheej.

Lub Hemi 5.7 tseem tau nruab nrog crossflow txhuas lub tog raj kheej taub hau, dual li qub thiab cov ntsaws ntsaws rau ib lub tog raj kheej. Lub chamber flatter kuj tau ua nrog rhawv ntawm ob sab, uas ua rau kom ua tau zoo ntawm lub tshuab tsav. 

Kev tswj hwm uas ua rau muaj kev ua haujlwm zoo ntawm lub cav

Thawj tswj saib yog lub camshaft. Nws yog lub luag haujlwm rau kev ua haujlwm ntawm cov khoom noj thiab cov pa tawm ua tsaug rau cov pushers nyob rau hauv lub valve levers. Cov khoom tseem ceeb kuj muaj xws li beehive valve springs thiab hydraulic roller tappets.

Cov neeg tsim qauv kuj tau xaiv rau Multi-Displacement System cylinder deactivation system. Qhov no ua rau muaj kev txo qis hauv kev siv roj ntxiv nrog rau cov pa emissions. Lub tshuab ua haujlwm los ntawm kev kaw cov roj mus rau plaub lub tog raj kheej - ob qho tib si - thiab tawm hauv cov khoom noj thiab cov pa tawm kaw, tswj cov roj ntws los ntawm ib tus neeg lub valve lifters.
