When building an engine, it's the little things that separate good engines and great ones. On initial start-up, getting a quick piston ring seal is critical—and having a clean, properly lubricated ...

SAE Transactions, Vol. 96, Section 7: FUELS AND LUBRICANTS (1987), pp. 240-257 (18 pages) Extensive measurements of oil film temperature and mainly of friction losses have been performed on an ...

Developing new engines that perform better, weigh less, use less fuel, and meet stringent emissions standards is the primary goal of most engineers and automotive corporations. Companies continually ...

In an engine, the relationship between the valves and the pistons is a precarious one. If there is too little space, they can collide. If this happens, the resulting carnage require replacing one of ...

It is desired to minimize clearance between the piston and the cylinder to reduce noise and suppress vibration. Although significant effort has been made for this purpose, increased piston friction ...
