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

Piston Velocities and Piston Work
Aircraft Engineering and Aerospace Technology, 1950WHEN 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.

The piston ring or the piston seal?
Russian Engineering Research, 2010Improvement 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 Vibration in Piston-Cylinder Systems
Journal of Fluids Engineering, 1980The motion of a cylindrical piston falling in a liquid filled vertical cylinder is analyzed. It is found that concentric motion is impossible and that flow induced vibration is always associated with such piston-cylinder systems. If the clearance over radius ratio is larger than a certain critical value, βcr, severe wobble and piston-cylinder contact ...
