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 ...

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 ...

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 ...

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 ...

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

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

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 ...

Free piston engines could achieve efficiencies of 50% which is almost double a regular gas combustion engine. However, new super efficient diesel engines could be even better, plus diesels would be ...

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 ...
