Piston rings are the seals in your cylinders, giving you better compression and power, but what happens if they wear or break ...

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 ...

Heat is also a byproduct of friction. Think about rubbing your hands together to warm them up. The faster you rub your hands together, the hotter they get. Now think about the pistons in your ...

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 10.6-litre, 2-stroke, 3-cylinder, opposed-piston Achates engine already meets 2027 regulations while being lighter. But hey, relax. That company also said that by 2030 50% of its new vehicle sales ...

Some of the world’s most complicated engines were created to achieve a specific objective. These engines were built to ...

Mazda's five-decade-long, largely futile efforts on behalf of the rotary engine demonstrate how difficult it is to unseat the conventional piston engine. Yet new concepts continue to emerge, ...

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 ...

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 ...
