摘要：
A poppet valve (10) has a disk-shaped head (12), an elongated stem (16), and a tapered neck (24) between the head (12) and the stem (16). The neck (24) has an outer surface (32) with an undulating circumferential contour. The undulating circumferential contour improves component strength and heat transfer efficiency, and may also influence valve rotation and inlet charge swirl.
