Weiss, D., Beno, S., Jordan, C., and Rohatgi, P., "Comparative Small Engine Testing Using Hybrid Composite Cylinder Liners," SAE Technical Paper 2016-32-0022, 2016, doi:10.4271/2016-32-0022.
Cylinder liners exert a major influence on engine performance, reliability, durability and maintenance. Various combinations of nonmetallic reinforcements and coatings have been used to improve the tribological performance of sleeves or surfaces used in compressors and internal combustion engines in four stroke, two stroke and rotary configurations. In this paper we report the use of a hybrid composite containing silicon carbide and graphite in an aluminum alloy matrix to improve the performance of various small engines and compressors. Material properties of the base material, as well as comparative dynamometer testing, are presented.
