A normal Wankel has a triangle rotor spinning in a peanut-shaped housing. Liquid Piston flips that; now the peanut rotor spins inside a triangle housing. That small change makes a big difference. The ...

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 ...

Industrial, environmental, and medical devices rely on pumps for a wide range of applications. Among the many pump types available, piston pumps and peristaltic pumps are frequently compared due to ...

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 ...

Developing new engines that perform better, weigh less, use less fuel, and meet stringent emissions standards is the primary goal of most engineers and automotive corporations. Companies continually ...

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 ...
