Belt versus chain

Study on the CO2 saving potential of the timing drive

  • 69 Accesses


Regarding the ongoing efforts to reduce CO2 emissions of internal combustion engines, the potential friction benefits of toothed-belt drives become more important. In the course of the present study — which has been carried out by FEV on behalf of the belt drive system suppliers Contitech, Dayco and Gates — differences between chain and toothed-belt drives, with respect to friction, as well as noise-relevant excitations were quantified based on test bench investigations, also, the impact on fuel consumption and NVH was evaluated.
