CANTON Over the past 15 years C. Mitchell Boulton has been working to make something old new again. Doing what he described as a retirement hobby, Boulton began reverse engineering a radial aircraft ...

When learning about the design of a machine or mechanism, reading and watching videos is certainly effective, but it’s hard to beat hands-on experimentation. In the video after the break, [Brick ...

Honda might be looking back to early aeronautics in its latest bid to make variable compression engines simpler and sturdier. The engine is designed to take advantage of the simple crank design of ...

Like all good engineers, those designing aircraft engines are greedy. They always want more power, more durability, and more efficiency. They also want it in the smallest, lightest package possible.

When a crop-duster fires up, its engine usually coughs, wheezes and belches smoke before settling down to a rumble. Gerald Breckenridge would like to change that. He would much prefer the whine of a ...

Click to open image viewer. The XR-7755-3 is the largest, most powerful reciprocating aircraft engine in the world. During World War II, the U.S. Army Air Forces requested an engine with high takeoff ...

As the automotive propulsion industry shifts toward electrification, the last-of-breed combustion engines are a stultifyingly similar bunch, focused around the same CAD-optimized 500cc cylinder ...

While the bright yellow fuselage has been restored, it’s the front section of the biplane that’s unique. A turboprop engine has replaced a radial piston engine. It’s the work of Turbines Inc., which ...

One of the many challenges facing engine designers is the need to increase power output while simultaneously retaining or improving efficiency. Although a four-cylinder engine is still an engineering ...

Matt Nelson is an automotive journalist with nearly a decade of experience in all things cars. He's spent years working at dealerships in sales, finance, and service. He's since traded in his pens and ...

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 ...
