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 ...

Dimpled pistons might sound strange, but some say they could be the future for diesel power. We've looked at the arguments ...

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 ...

Sandia National Laboratory led by Sandia researcher Peter Van Blarigan that has been testing physical components of free-piston engines which could be 50% efficient. This is about twice as good as ...

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 ...

An engine with no crankshaft, where the pistons float on air? It’s not a dream; it’s a free piston engine and it might be the next major advance in car tech. When we think of automotive technology of ...

Despite being in existence and undergoing continuous development for 140 years, the internal combustion engine can still be improved, and Volvo recently highlighted one of its recent improvements that ...

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 ...
