Engineers have a lot to think about when designing new engines, and one of the biggest considerations is the shape of the ...

Piston-engined fighters ruled the roost for thirty years. A brutal survival of the fittest ensured a rapid evolution of these characterful machines; the final fighters were over six times faster and ...

The internal combustion engine, for all its mechanical sophistication, still runs on a 19th-century mechanical idea: pistons rising and falling, a crankshaft spinning, a steam-age architecture ...

The new standards replace specifications from 1977 and aim to align India's automobile market with global efficiency and ...

Golf balls have dimples, so they fly farther than balls that don't. Apply the same principle to diesel engines, and you have a gross oversimplification of why dimpled pistons were invented. It's a ...

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 ...

Everyone generally knows about piston and rotary engines, with many a flamewar having been waged over the pros and cons of each design. The “correct” answer is thus to combine both into a single ...

A broken piston can happen for many reasons, from detonation and overheating to lubrication issues or mechanical stress. In this video, we take a closer look at what may have caused the piston to fail ...

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 engine, ...

Each occupant of a turbine-powered aircraft is assumed to weigh 200 lb., thus allowing for stowed luggage and carry-on items. In the case of piston-engine airplanes, we assume each occupant weighs 170 ...

The story of the most over-engineered Honda motorcycle ever made.
