The Wankel rotary engine is one of the most unique and innovative engine designs ever created. Unlike the conventional piston ...

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 ...

The rotary engine is easily one of the most controversial automotive engines. There's a pretty interesting explanation for ...

This engine is the basis of the modern “Wankel” rotary engine. Piston powered engines, chiefly the Otto and Diesel cycle, are current kings of the internal combustion mountain. Piston powered ...

The history of the rotary engine is a strange and wonderful tale that dates back as far as 1588 when Ramelli invented the first rotary-piston-type water pump. Almost 200 years later James Watt ...

Wondering if rotary engines need oil changes? Learn how their lubrication works and why regular oil maintenance is still ...

The new RX-8 sport coupe is the only car on the market to have this power plant (Mazda’s other products have piston engines). But the rotary had to come a long way to be here. Its presence under ...

There’s a new spin on the rotary engine. Liquid Piston, a Connecticut-based engineering firm, has turned the classic Wankel engine design inside out to create a more efficient, and cleaner ...

Mercedes put serious research into the engine, and GM even believed that the rotary would supersede the piston engine in everything from the Vega to the Corvette. It appeared that the Wankel ...

But the idea could definitely work by exploiting the great advantage of the rotary piston engine while eliminating its biggest disadvantage. The low-vibration operation of this engine concept is ...

heavy-fueled 25 hp rotary combustion engine that produces the same power output as piston diesel engines up to 10 times larger. Following its subcontract with Parsons, LiquidPiston received an ...

Transforming the up-and-down movement of a piston into a rotational one means losing some power due to friction, and that's why many engineers tried to create a rotary engine. But only one made it ...
