Excerpt

The trend of increasing installation clearances in order to reduce frictional losses, being driven by the problem of CO2 emissions, leads once again to acoustic optimisation having an increased significance. Mahle uses secondary piston motion measurements in a small, three-cylinder gasoline engine to demonstrate the effects of changes in the skirt rigidity, or rigidity distribution over the length of the skirt, on the piston motion, and therefore on the noise excitation. …
