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 ...

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 ...

1. EcoMotors is developing high-efficiency engines — specifically the unique opoc (Opposed Piston Opposed Cylinder) engine — for use in cars, light trucks, marine applications, agricultural vehicles, ...

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 ...

EVERY so often someone tries to design a new internal-combustion engine. Few make it from the laboratory bench to the big bad world. The last serious attempt, Felix Wankel's rotary engine, lingers on ...
