Summary:Owing to the harsh operating environment inside an engine, the engine valves have a durability issue and exhibit the characteristics of accelerated fatigue failure under the influence of the dynamic load because of their dynamic behavior. This study proposes a fatigue life evaluation method using the maximum impact stress that can accurately evaluate the fatigue life of engine valves. In addition, the major engine design factors affecting the dynamic behavior of an engine valves were derived. It was confirmed that the impact speed between the valve head and seat is closely related to the fatigue characteristics of the engine valve.
