Despite electrification taking the lead as an alternative source of propulsion, some automakers, including Toyota, Honda, and ...

At one point in automotive history, engineers believed they had found a completely new path for internal combustion. The ...

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...

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 ...

Rotary engines (also known as Wankel engines and Wankel rotary engines) are quite different from piston or "reciprocating" engines. One of the distinguishing features is that they don't need valves to ...

In theory, Wankel-style rotary internal combustion engines have many advantages: they ditch the cumbersome crankcase and piston design, replacing it with a simple, single-chamber design and a thick, ...

How the 13B-MSP Renesis evolved from earlier Mazda rotary designs, technical features explained, and common problems and maintenance issues discussed. The 13B-MSP Renesis rotary engine powered the ...

The engine. It's a testament to its initial design, as whether it's in a V-configuration, W, H, or even flat, it really hasn't changed its operation since its invention. That is, of course, except for ...

We live in an age of downsizing in the automotive world. Super and hypercar manufacturers like McLaren and Ferrari are ditching big-capacity, high-cylinder count engines in favor of boosted V6 and V8 ...
