In most instances, cracks were caused by high cyclic pressures and high temperatures resulting most probably from detonation. At times, fractures or cracks (or both) were also caused by a combination of (1) unfavorable temperature distribution and possibly excessive pressures around the cylinder barrel, (2) un-nitrided internal surfaces of cylinder barrels, and (3) inadequate thread contours, which caused high stress concentrations at the thread roots.
