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 ...

Free-piston engine generators and linear machines represent an innovative departure from conventional rotary systems, offering high thermal efficiency and operational flexibility by eliminating the ...

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 ...

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 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 ...

We all know how a conventional internal combustion engine works, with a piston and a crankshaft. But that’s by no means the only way to make an engine, and one of the slightly more unusual ...

Toyota is hot on hydrogen fuel cells for its next-generation cars, but it’s not going cold on internal combustion just yet. The company’s R&D division has developed a Free Piston Engine Linear ...

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 ...

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 ...

You'd think measuring an engine's displacement would be simple, but there's a long history of trying to figure out how to ...

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