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

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 ...

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 ...

Bore and stroke are important measurements when it comes to calculating an engines displacement, and the kind of performance ...

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 ...

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 ...

Technical manoeuvring to push regulatory boundaries for the slightest performance edge without actually breaking any rules is ...

Pistons play the ultimate role in an engine, but despite that, it's still hard to fully wrap your head around all the forces involved. There are plenty of moving parts in an internal combustion engine ...

You've probably heard of two- and four-stroke engines, but what are the four strokes of a gasoline engine? And how do they ...

Piston-engined fighters ruled the roost for thirty years. A brutal survival of the fittest ensured a rapid evolution of these characterful machines; the final fighters were over six times faster and ...
