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 ...

Subaru's recent patent filing reveals plans to use a turbine engine in extended-range electric vehicles (EREVs).

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 ...

One of the many challenges facing engine designers is the need to increase power output while simultaneously retaining or improving efficiency. Although a four-cylinder engine is still an engineering ...

Modern piston engines are incorporating advancements such as fuel injection, turbocharging, and electronic controls (like Lycoming's iE2 system). Weight reduction is a key focus; engines like the ...

The first recognizable internal combustion engine was developed by Nikolaus Otto in 1861. Since then, the gasoline-powered engine has evolved immensely. However, the principles that underlie how ...

In this video, I take on an exciting engineering challenge: combining two internal combustion engines into a single opposed-piston engine. This unique project improves balance, reduces vibrations, and ...

It would have been revolutionary: an internal combustion engine without oil. And it might have worked. But lots of real-world ...

Toyota is revolutionizing the automotive industry with its groundbreaking W-Piston Free-Piston Engine, which achieves an impressive 50% efficiency. This innovation not only promises enhanced ...

While Tesla, General Motors, Nissan, BMW and other automakers doggedly push to bring battery-powered vehicles into the mainstream, Achates (a-KATE-ezz) Power engineers are betting that an old ...

Kawasaki Motors has partnered with Dronamics to integrate aero piston engines into the Black Swan cargo drone.
