Abstract
Timing drive by chain is commonly used in passenger cars especially in diesel engines with double overhead camshafts owing to their numerous advantages compared with belt drive systems. However, one of the important subjects to take into account is the timing chain noise, so-called "meshing noise" that can be perceived by the driver. The manufacturer's efforts to reduce it, are focused on reducing the sprocket-chain vibrations (Young et al., 2003), improving chain performances (www.smartchain.nl), and modifying the resonance frequencies of related parts (Sopouch et al., 2003). However, these efforts could be compromised due to assembly process variation. In this paper, a procedure to assess and control the timing chain noise variation has been suggested.
