On this feature of the FRAME, we explore the technology of the manufacturing processes behind Mazda’s Rotary Engine. Do you ...

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 ...

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 ...

Chris Bruce has worked in the automotive industry since 2011 and has written thousands of stories about cars, motorsports, and motorcycles in that time. He has written for Autoblog, Autoviva, CarFax, ...

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, ...

It's as crazy as it sounds. Rolls Royce developed a diesel rotary engine for military applications. Because diesel engines ...

Language is an imperfect medium, but it's what we've got, so let's go with it. Determining the swept volume of inventor Felix Wankel's rotary engine can generate more arguments than claiming what a GT ...

Wankel rotary engine powered thousands of aircraft. One of several problems: It spewed castor oil on its pilots.

Almost every internal combustion vehicle on the planet today uses the classic piston engine. These run by converting heat energy into reciprocating motion, and then rotary motion that ultimately ...

Most vehicles use a piston engine similar to the one-cylinder, four-stroke motor in the first car ever made, Karl Benz's Patent Motorwagen. Lately, a more fuel-efficient and emissions-friendly engine ...

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 ...
