Engineers have a lot to think about when designing new engines, and one of the biggest considerations is the shape of the ...

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 ...

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 ...

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

The internal combustion engine, for all its mechanical sophistication, still runs on a 19th-century mechanical idea: pistons rising and falling, a crankshaft spinning, a steam-age architecture ...

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 ...

Despite being in use for more than a century, combustion engines are still way to complex and inefficient in turing fossil fuel to mechanical work. Naturally, engineers have been battling their way ...
