Critical Cosmetic Quality Inspection of Engine Valves

Engine valves are critical components of the engine intake and exhaust systems, required to maintain stable performance under high-temperature, high-pressure, and high-speed operating environments. Any scratches, chipping, impact dents, or machining anomalies on the valve face, stem, tip, or chamfer can compromise sealing integrity, durability, and assembly quality.

This case covers multiple types of engine valves, which may vary in length, profile contour, diameter, valve face ratio, or stem size. In addition to identifying cracks, pinholes, and subtle surface defects, the inspection workflow can simultaneously determine the engine valve category based on visual features.
