Quantitative two-dimensional measurement of oil-film thickness by laser-induced fluorescence in a piston-ring model experiment.

Applied Optics, 2016
This paper describes advances in using laser-induced fluorescence of dyes for imaging the thickness of oil films in a rotating ring tribometer with optical access, an experiment representing a sliding piston ring in an internal combustion engine.

Use of acceleration and optical waypoint measurements to estimate piston trajectory in an impulse facility

Shock Waves, 2019
This paper describes a prototype device to estimate the trajectory of the piston in a free-piston driver. The device, which screws to the front face of the piston, has an internal data acquisition system which triggers upon piston launch and records the acceleration history across the complete piston stroke.

Piston's thermal fatigue testing device for thermal engine in motor vehicle, has optical pyrometer that measures maximum temperature in part of piston, and optical measurement unit that indicates structural damage of piston

2011
The device has an electromagnetic induction based heating unit i.e. solenoid coil (12), arranged in a cup (21) of a piston, and adapted to realize heating cycles. A channel (13) of a cooling circuit is permanently supplied with a fluid at temperature lower than maximum temperature reached at the time of the heating cycles. The cooling circuit is placed
