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 ...

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 ...

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 ...

The mind-bending world of birotary engines - a hybrid of piston and rotary technology that could revolutionize aviation. But ...

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 ...

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

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 ...

DETROIT – While Tesla, General Motors, Nissan, BMW and other automakers doggedly push to bring battery-powered vehicles into the mainstream, Achates Power Inc. engineers are betting that an old ...
