FCGear TimingGear/it

Descrizione
Lo scopo degli ingranaggi di distribuzione è quello di consentire all'albero a camme e all'albero motore di far ruotare la catena di distribuzione. L'albero motore gira per muovere i pistoni su e giù all'interno dei cilindri. L'albero a camme ruota per consentire l'apertura e la chiusura delle valvole di aspirazione e di scarico sui cilindri. Questi componenti sono importanti per la corretta sincronizzazione del motore.

Timing gears are connected to a timing belt or timing chain.
