Valve measurements for 4-stroke Otto engines

Intake and exhaust valves are important precision components in any gasoline engine. The production quality of the valves is becoming more and more important - in mono-metal valves as well as in bi-metal or hollow valves. In times of downsizing, increased speeds, higher injection pressures and the increased use of turbochargers increase the demands on the manufacturing quality of valves. The measurement tolerances of the workpieces are becoming smaller and thus the demands on metrology greater.
