In this video, I take on an exciting engineering challenge: combining two internal combustion engines into a single opposed-piston engine. This unique project improves balance, reduces vibrations, and ...

In a conventional application, there are three rings per piston. The top ring is called the compression ring. Its purpose is to seal the combustion gas pressure, transfer heat from the piston to the ...

Remarkable innovations have been made to automotive technology since Karl Benz introduced the world to the "Motorwagen" in 1866 and Henry Ford gave rise to the American auto industry with the Model T ...

The first recognizable internal combustion engine was developed by Nikolaus Otto in 1861. Since then, the gasoline-powered engine has evolved immensely. However, the principles that underlie how ...

More an ancient tool than a groundbreaking gadget, the fire piston relies on basic chemistry to ignite a campfire with the ...

When we here in the modern age think of an “engine,” we are usually thinking of a four-stroke, four-cylinder, gasoline-fed, internal-combustion engine with the valves on the top. But why must that be ...

I can never resist a good oddball engine, and this one’s pedigree is impressive. See if you can bend your mind around it. Most of you reading this probably have at least a basic understanding of how ...

Picture a large-displacement piston engine in your mind. Perhaps the first image to come up is an engine you'd see in construction equipment, like the 20-cylinder quad-turbo 106-liter powerplant from ...
