Almost as interesting as the design is the use of fluid simulations and OnShape’s version control to do software-development-like branch and merge to check some of the proposed changes. There’s also a ...

LiquidPiston says it is currently in negotiations with potential partners to bring its small engines to market. Shkolnik also said the engines could be used as range-extenders for mass market electric ...

(CAMBRIDGE, Mass.) -- Since their invention in the late 1700s when French-born British physicist Denis Papin, the inventor of the pressure cooker, proposed the piston principle, pistons have been used ...

Free-piston engine generators and linear machines represent an innovative departure from conventional rotary systems, offering high thermal efficiency and operational flexibility by eliminating the ...

Ford once sketched a road where an engine's pistons never saw oil and engines ran hotter on purpose. In a late‑1980s patent application filed and granted in Europe, the company described an "uncooled ...

Researchers have developed a new way to design pistons that replaces their conventional rigid elements with a mechanism using compressible structures inside a membrane made of soft materials. The ...
