Timing Belt-In-Oil (BIO) System
In 2007, Dayco introduced the first Timing Belt-in-Oil system for automotive applications, a technological breakthrough that directly addresses customer focus on lower emissions, increased fuel efficiency and less tension on the drives.
The Belt-in-Oil system, which includes Dayco's patented belt and tensioner, weighs less, has lower stretch, reduces friction and is quieter than traditional chain-driven components. For our customers, this translates into higher engine performance, lower emissions and improved fuel economy. Built inside of the engine and in direct contact with engine oil, the Dayco Timing Belt-in-Oil also reduces engine packaging, resulting in fewer individual components and lower weight.
