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

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.

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 Vibration in Piston-Cylinder Systems

Journal of Fluids Engineering, 1980
The 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 ...

Simulation of the Piston and Piston Ring Dynamic

SAE Technical Paper Series, 2001
<div class="htmlview paragraph">All reciprocating engines from the first Diesel engine to turbocharged formula 1 engines require a sealing of the combustion chamber. This sealing is realized by the compression rings. Today a set of two compression rings and one oil control ring is standard, the large variety of available solution demonstrate the ...
