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 ...

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, ...

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 ...

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 ...

In this video, you'll see the different types of engines and propulsion systems used for aircraft, my favorite ones: Turbojet, turboprop, turboshaft, and turbofan. You'll also see the Ramjet engine. I ...
