Abstract

E' descritto un motore a combustione interna con cilindri a V con due linee di cilindri con, di volta in volta, un blocco testa cilindri coperto da un coperchio testa cilindri e, frontalmente, da un coperchio frontale in cui sono disposti alberi camme che vengono azionati tramite rocchetti per catene da una catena comune che viene fatta passare in un involucro di cavità lungo uno spazio libero tra le due linee di cilindri. Per ridurre le fessure sulle superfici di tenuta che creano problemi di tenuta, l'involucro della cavità è disposto a distanza dalle superfici di separazione tra i blocchi teste cilindri e i coperchi teste cilindri ed è fissato esclusivamente tra i blocchi teste cilindri e i coperchi frontali.
