Belt in oil technology – the development continues

In regard to the development of the belt in oil (BIO) oil pump belt in the VW 1.6-litre TDi engine used in many VAG vehicles, Dayco is able to highlight the fact that the use of BIO solutions is continuing to increase.

Dayco, the company that pioneered BIO development on behalf of the VMs, is therefore delighted to announce that, in recognition of Dayco’s deep technical capabilities, GM has approved Dayco as the OE/OES BIO supplier for its 1.0 and 1.2-litre petrol engines produced for the LATAM region; the incumbent supplier is being replaced due to the superior performance and advanced technological level of the Dayco belt.

With emissions reduction, noise abatement and weight saving as key VM goals, the BIO concept plays an important role in delivering these objectives. However, having to function in a chemically aggressive environment throughout the engine’s entire service life, and in contrasting climates across the globe, demands precise design and enhanced materials.
