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, ...

Numerous articles and stories have been prepared by hundreds of experts on how to improve the internal combustion (IC) engine for more speed, power or what have you. Millions of dollars worth of ...

Rotary engines differ from conventional ones in many respects — and one of them is the fact that they use two different spark ...

The engine in question was the Wankel rotary, named after German engineer Felix Wankel, who first patented the concept in 1929. Instead of pistons moving back and forth, the rotary engine used a ...

There are many different forms of internal combustion engines, but most use the same basic principle. Explosions in the combustion chamber move pistons up and down to spin a crankshaft. That ...

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 ...

A Wankel engine is a type of rotary engine, but not all rotary engines are Wankel engines. Wrapping your mind around this idea will help you to better understand the similarities as well as the ...

Good news, everyone! Mazda is not only reassembling a dedicated team of engineers for rotary engine development, as we’ve reported earlier, but today it also announced its intention to expedite ...

Add Yahoo as a preferred source to see more of our stories on Google. Perfectly tuning the heat range of an engine's spark plugs is something of a dark art to all but the most well versed tuners and ...

The rotary is kind of like the Rudy (from the movie “Rudy”) of engines. It’s a little smaller than the others, and might not be quite as good, but you can’t help rooting for it. Mazda says that you ...
