ABSTRACT A new piston secondary motion analysis has been developed that accurately predicts piston strength and the slap noise that occurs when the engine is running. For this secondary motion ...

Piston rings have significant influences on the engine performance and tribology. The effect of such rings has a delicate relation with the axial motion in the groove. By simultaneously measuring the ...

The process of vortex ring generation and propagation has received substantial treatment in the literature. A common ring generation geometry consists of a piston moving through tube that exits into a ...

This collection of cam-related phenomena is intended to take you beyond the degree-it-in and set-the-valve-lash plateau. In concert with what you may already know about camshaft types, selection, and ...

Insufficient air tightness of the connecting rod can cause gas leakage in the cylinder, similar to a leaking container that ...

Every new electric-car announcement is touted as another nail in the coffin of the internal-combustion engine. But the internal-combustion engine keeps fighting back. The latest counterpunch comes by ...

Friction slows equipment, wears components, and renders motion profiles unpredictable. One remedy for linear-motion friction is to use air bearings to carry normally contacting components while ...

It is generally acknowledged that connecting rod geometry, particularly center-to-center length, can have a material influence on a variety of engine conditions. These include specific relationships ...

The process of vortex ring generation and propagation has received substantial treatment in the literature. A common ring generation geometry consists of a piston moving through tube that exits into a ...
