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 ...

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 ...

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, ...

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 ...

Everyone generally knows about piston and rotary engines, with many a flamewar having been waged over the pros and cons of each design. The “correct” answer is thus to combine both into a single ...

The continuous drive for enhanced efficiency and reliability in modern diesel engines has prompted extensive research into the thermal management of critical components such as pistons. The ...
