摘要： A valve for an engine cylinder includes a head. The valve is selectively moveable between a closed position in which the head blocks a port and an open position in which the head unblocks the port. A lower stem is formed as one-piece with the head, and a thermal cavity formed within the lower stem. The thermal cavity is at least partially filled with a heat transfer medium. An upper stem is attached to the lower stem opposite the head. A thermal barrier is located adjacent a junction of the lower stem and the upper stem.

摘要： An engine assembly may include an engine structure supporting a camshaft and a valve lift mechanism. The camshaft may include a cam lobe and may define a longitudinally extending rotational axis. The valve lift mechanism may define a longitudinally extending cam engagement surface and a first side wall. The cam engagement surface may be engaged with the cam lobe at a first location. The first side wall may be fixed to the cam engagement surface and may include first and second portions. The first portion may extend from the cam engagement surface. The second portion may extend continuously inward from an end of the first portion. The inward extent of the second portion may be greater than or equal to a first height at the first location defined from the cam engagement surface to the end of the first portion.

摘要： An exhaust valve stem seal assembly includes a casing and an elastomeric seal coupled to the casing. The elastomeric seal includes a stem seal portion for sealing against a stem of an exhaust valve. The stem seal portion includes a gas lip that extends radially inward. The casing includes a frustoconical shoulder extending radially inward toward a valve axis to a distal edge. The frustoconical shoulder defines an angle relative to a plane perpendicular to the valve axis between the range of 5° and 45°. The distal edge of the frustoconical shoulder is disposed behind and is substantially aligned with the gas lip along the valve axis.
