Engine valves are mechanical components used in internal combustion engines to allow or restrict the flow of fluid or gas to and from the combustion chambers or cylinders during engine operation. Functionally, they perform similarly to many other types of valves in that they block or pass flow, however, they are a purely mechanical device that interfaces with other engine components such as rocker arms in order to open and close in the correct sequence and with the correct timing. The term engine valve may also refer to a type of check valve that is used for air injection as part of the emission control and exhaust gas recirculation systems in vehicles. This type of engine valve will not be addressed in this article. Engine valves are common to many types of combustion engines

Tapered Roller Bearings consist of four basic components: the cone (inner ring), the cup (outer ring), the tapered rollers (rolling elements), and the cage (roller retainer). The cone has a shoulder called the cone rib, which makes contact with the end of the roller to ensure alignment and resist axial loads. Due to the tapered races, the bearing will handle any combination of radial and thrust loads. Proper use of Tapered Roller Bearings requires two opposed bearings, where each applies a...
