Piston Rings and Pistons

2023
General-These specifications are in general use and have been adopted as an SAE Standard primarily for conventional automotive type engines. This category includes passenger car and light or medium duty truck, tractor, and industrial engines, as well as some compressors. For heavy duty gasoline and diesel engine it may be necessary to depart from these

The piston ring or the piston seal?

Russian Engineering Research, 2010
Improvement in the efficiency of piston compression rings is considered. By taking account of the gas dynamics in determining piston-ring geometry and developing a system of piston rings and piston seals for various internal combustion engines, their basic performance and environmental characteristics may be improved.

Piston Velocities and Piston Work

Aircraft Engineering and Aerospace Technology, 1950
WHEN evaluating engine efficiencies, mean effective pressures or the work done by the piston in internal combustion engines or compressors, it is generally assumed that the state of the working fluid is uniform throughout its mass. From this it follows that the expression for work where P denotes pressure and V, volume, holds.
