A phenomenon rarely heard of these days, is that of ring flutter. Manifesting itself in the form of unusual wear characteristics and possibly high exhaust gas blow-by, particularly at light load conditions, ring flutter if left unchecked, can even cause pre-ignition/detonation of the incoming fuel-air charge, eventually leading to piston failure. The solution however, is not always that obvious. You may always hear that the root of the problem is all to do with the acceleration and...
