Analysis of the Blow-by in Piston Ring Pack of the Diesel Engine
Favourable sealing performance of the piston ring pack is an important condition for the engine to maintain efficient, stable operation. Analysis on blow-by in piston ring pack for an inline six cylinder diesel engine was carried out, through the ...

Piston problem to the isentropic Euler equations for modified Chaplygin gas [PDF]
In this paper, we solve constructively the piston problem for one-dimensional isentropic Euler equations of modified Chaplygin gas. In solutions, we prove rigorously the global existence and uniqueness of a shock wave separating constant states ahead of the piston when the piston pushed forward into the gas.

A model for vortex ring formation in a starting buoyant plume [PDF]
Vortex ring formation in a starting axisymmetric buoyant plume is considered. A model describing the process is proposed and a physical explanation based on the Kelvin–Benjamin variational principle for steady vortex rings is provided.

Piston Rod Coating Material Study of Reciprocating Sealing Experiment Based on Sterling Seal
Sterling seal is a commonly used reciprocating seal, in which the PTFE ring of the seal and the surface material of the piston rod play an important role in the reciprocating sealing process.

A universal time scale for vortex ring formation [PDF]
The formation of vortex rings generated through impulsively started jets is studied experimentally. Utilizing a piston/cylinder arrangement in a water tank, the velocity and vorticity fields of vortex rings are obtained using digital particle image ...

The Effect of Compression Ring Profile on the Friction Force in an Internal Combustion Engine [PDF]
In an internal combustion engine piston, piston ring and cylinder are the most important assembly for transmitting the forces produced by the combustion process. The friction between piston ring pack and cylinder accounts for major portion of friction in
