Analysis of Aluminum and Steel Pistons: Comparison of Friction, Piston Temperature, and Combustion
Volume 2: Fuels; Numerical Simulation; Engine Design, Lubrication, and Applications, 2013While steel pistons have been in use for a long time in commercial vehicle diesel engines, the first series production applications for passenger car diesel engines are currently imminent. The main reason for the use of steel pistons in high speed diesel engines is not, as maybe initially hypothesized, the increasing requirements on the component ...

Comparison of Titanium and Robinson Stainless Steel Stapes Piston Prostheses
Otology & Neurotology, 2005Although stainless steel stapes prostheses have generally been considered magnetic resonance imaging safe, there is concern that this may change with the development of more powerful imaging systems. The objective of the study was to determine whether a titanium piston stapes prosthesis would be audiometrically and surgically equivalent to a Robinson ...
