[MacGyver] [Lou Wozniak] is on a mission to build an internal combustion engine using only hardware store parts. What you see above is his third attempt at it. Depending on your hardware store ...

Researchers aim to meld the best attributes of both the power-dense two-stroke and the vastly cleaner four-stroke engines.

Four stroke engines are often more fuel efficient and cleaner than equivalent two stroke designs, but may be heavier and more complex to design. They are the most common type of internal combustion ...

Fundamentals of combustion and pollutant formations in application to internal combustion engines, turbines, and fire safety. Concepts include flame structure, flame speed, flammability,ignition, ...

Although simple in concept, the complexity of the internal combustion engine is mind-boggling. Most of the time we take it for granted when we turn the ignition key, shift into gear and step on ...

We had no idea that what’s needed to convert an internal combustion engine to steam power is actually rather trivial. [David Nash] shows us how it’s done by performing the alterations on the ...

Porsche has revealed a strange (and possibly brilliant) idea for a six-stroke combustion engine. If you don't know the ...
