A technique rarely taught in schools, this video demonstrates how to create cylinder block honing heads for large piston ...

The world's largest piston engine is the Wärtsilä RT-Flex96C inline-14 diesel, which generates 110,000 hp, stands 44 feet ...

In this video, I take on an exciting engineering challenge: combining two internal combustion engines into a single ...

The ZR1’s turbos are the largest ever installed on a production passenger car, according to GM. The inertia of such large ...

While the patent shows off an oval-piston V12, it could work on smaller engines, too We know the death of the internal-combustion engine has been greatly exaggerated, what with the imminent return ...

This effectively gives the pistons double duty, performing the work normally handled by valves in a typical combustion engine—which means that the common drawback of direct injection, carbon ...

Most engines inject petrol and air, compress the fuel, ignite the fuel, then push the spent gases into the exhaust, with the pistons working in a down, up, down, up movement – or four separate ...

Piston engines rely on oxygen to efficiently burn fuel, but as you fly higher, there's less oxygen in the air. Most piston-engined aircraft would have difficulty flying at airliner altitudes.

DeltaHawk Engines, founded in 1996 and based in Racine, Wisconsin, designs and builds FAA-certified, jet-fueled piston engines for general aviation aircraft and hybrid-power systems.
