International Classification:

F02M 300

US Classification:

1231883

Abstract:

A first part of an engine valve (10) is centered on an axis (A) and comprises a hollow metal member (100) having an outwardly flared first end portion (102) and a second end portion (104). The hollow metal member (100) has a chamber (106) extending axially throughout the member. The chamber (106) is open at the first end portion (102). A second part of the engine valve (10) is centered on the axis (A) and comprises a metal piece (130) coaxial with the hollow metal member (100). The metal piece (130) has first and second ends (132 and 134). The first end (132) has a first weld connection to the second end portion (104) of the hollow metal member (100). The metal piece (130) has a solid cross-section portion between the first and second ends (132 and 134). The metal piece (130) has a circumferential groove (150) in the solid cross-section portion. A metal cap (160) has a periphery (166) and a second weld connection (172) at the periphery to the outwardly flared first end portion (104) of the hollow metal member (100).

International Classification:

F01L 320

US Classification:

1231883

Abstract:

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.

Assignee:

TRW Inc. - Lyndhurst OH

International Classification:

B22F 900

US Classification:

75246

Abstract:

A powder composition is suitable for making a valve seat insert having good machinability and high temperature wear resistance. The composition consists essentially of about 0. 5%-5% nickel, about 1%-10% molybdenum, less than 0. 1% copper, about 0. 4%-1. 2% carbon, the remainder being iron. The ratio of nickel to molybdenum is about 0. 25:1 to 1:1. The nickel and molybdenum are preferably present as a blend of elemental nickel, elemental molybdenum, and a pre-alloyed powder in which nickel and molybdenum are pre-alloyed with iron.
