Rotary engines have an aura of cool. In games of Top Trumps, the V12 might have been king, but a rotary was a joker, a wild card. A lack of mainstream success no doubt contributes; there are reasons ...

One of its first tasks will be analyzing an engine design that eliminates the mechanism linking the crankshaft and camshaft, and controls the valves independently. The valves would, therefore, be more ...

Research and Development (R&D) company Relative Motion Technologies, led by visionary Dr. Ibrahim Hanna, has introduced a revolutionary innovation called the Relative Motion Engine. It aims to ...

When it comes to unique engine designs, one of the most prolific is the trusty rotary configuration. Instead of featuring a number of spherical cylinders moving up and down like in most internal ...

We all know how a conventional internal combustion engine works, with a piston and a crankshaft. But that’s by no means the only way to make an engine, and one of the slightly more unusual ...

With a slogan like “The Future is Ecclectic,” we’d expect some interesting things from INNengine, a startup based in Spain. The company is showcasing a “one-stroke” engine that works as an opposed ...

We're not going to get into the whole "who made the first car" argument today. But there's not much doubt that the overall history of self-propelled vehicles goes back well beyond the Mercedes Patent ...

Internal combustion engines are literally the engines of the modern world. Without the invention of these genius mechanical creations, our world would be markedly different and the pace of life would ...
