An “Engineering Research Series” title. Valve wear and
its effect upon engine performance still presents a major
challenge to the tribologist. Although new valve materials and production techniques are constantly being developed, these advances have been outpaced by demands for increased engine performance. The drive for reduced oil consumption and exhaust emissions, use of
lead-replacement and low-sulphur fuels, and the introduction of alternative fuels such as gas all have implications for valve and seat insert wear.

Automotive Engine Valve Recession aims to provide the
reader with a complete understanding of valve recession. The
fundamental nature of contact and wear between valves and valve
seats is considered, followed by an outline of the essential
features of valve operation and the potentially serious problems
associated with wear and valve recession in automobile engines. An
overview is
then given of an experimental study of valve wear and the
development of special apparatus for the simulation of engine
operating conditions carried out in the School of
Mechanical Engineering, University of Sheffield, UK.
