The world of automotive engineering is filled with innovation and experimentation, leading to some rather unusual engine designs that made it to production, albeit briefly. These engines often broke ...

If you look at aircraft from the Second World War or earlier, you'll notice that many of them have engines with large frontal areas and cylinders arranged about the propeller crankshaft. This a radial ...

Just because LEGO Technic is technically a toy doesn’t mean that you cannot do solid engineering with it, like building air-powered engines. After first building a simple air-powered piston ...

The 20th century was the age of the internal combustion engine. The fruits of industrial progress produced power plants tasked with everything from running generators to powering warplanes. The First ...

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 ...

Cirrus Aircraft has introduced a new variant of its popular single-engine SR-series aircraft, with a redesigned interior, updated electronics and displays, advanced safety systems and other comfort ...

Based on a Wright R-975 Whirlwind radial engine, the Hackel-Wright Chopper is unlike any motorcycle you've seen before. It borrows components from Harley and Toyota and is built by a guy named Al ...

A single atom inside of a reflective cavity could be enough to drive a piston in a tiny, quantum version of an engine. The essential feature of any engine is that it converts heat into work, which can ...
