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 ...

That fresh air is squeezed into a small pocket in the center of the cylinder as both pistons come together, where finally diesel fuel is directly injected, igniting the mixture and creating the power ...

More an ancient tool than a groundbreaking gadget, the fire piston relies on basic chemistry to ignite a campfire with the simple pump of a hand. The new Aviator's Ember from Aerohart applies ...

Science isn’t fun if we don’t try to break or bend its limits, but sometimes this rebellion doesn’t work. For instance, we don’t make triangular wheels, perforated windshields, or lead pistons for ...

Free-piston engine generators and linear machines represent an innovative departure from conventional rotary systems, offering high thermal efficiency and operational flexibility by eliminating the ...

If you are a motorhead, an unusual engine will immediately get your attention. Most vehicles today have either an inline or V-shaped configuration, so anything peculiar will immediately stick out. If ...

Just because LEGO Technic is technically a toy doesn’t mean that you cannot do solid engineering with it, like building ...

When you're at an airport and see propeller aircraft, you likely think it is powered by a piston engine. This is usually true among smaller planes, like the Cessa 172 Skyhawk and the Piper Archer, or ...

Ferrari has filed a patent for an engine with pill-shaped pistons, a radical departure from traditional circular piston designs. While Honda famously experimented with oval pistons in the late 1970s ...

Ferrari is exploring radical oval pistons that could shrink engines, boost efficiency, and reinvent how high-performance gas motors are designed for the next generation. For as long as internal ...
