By coupling these developments with strict KPMI design, simulation and analysis protocols, they were able to overcome the torsional stresses unique to ovate wire springs that previously severely limited their operating parameters. This was critical, as there are nearly 100 camshaft part numbers available for these applications. Springs are progressively wound using Kobe Super-Clean chrome silicon based wire that is heat treated and shot peened.
