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 ...

High-output engines live in a world of brutal cylinder pressures, extreme temperatures and razor-thin safety margins, and the humble piston sits at the center of that storm. When power levels climb, ...

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 ...

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 ...

Solid lubricants such as graphite and carbon fibre reinforced polymer form the EcoTough coating for diesel engine pistons to reduce friction, and improve efficiency, refinement and durability of ...

A “boxer” engine is one with cylinders positioned horizontally instead of vertically — the latter configuration found in inline and V-type engines — and the pistons move in the opposite direction from ...

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 ...

While there have been many unusual engine designs over the years, there haven't been many advancements involving the inner workings of the piston engine, except for higher-quality components, since ...

Over the roar from a 110-cc, two-cylinder engine, Pinnacle Engines founder James Cleeves (nicknamed Monty), pointed out a window in the block. "You can see the cylinder sleeve moving for the intake ...

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 ...

With the improvement of the steam engine (steam engine) by Wat, the industrial revolution occurred in the world. Although it is a steam engine which became to be utilized as a power source of various ...
