Wankel rotary engines, typically but not exclusively found in Mazdas, certainly lean on the "quirkier" side of modern powertrain systems, made quirkier because most rotary-powered cars on the road ...

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 ...

The rotary engine, previously a staple in Mazda's lineup, is an engine design that foregoes the round piston and singular chamber of a regular reciprocal internal combustion engine. Instead, the ...

Rotary engines made their biggest impact in Mazda sports cars, but a recent episode of "Jay Leno's Garage" delves into the rotary's earlier history. Before it was popularized by Mazda, the rotary ...

Antonio is a chemical engineering student pursuing his master's degree in chemical engineering and sustainable processes. Throughout his academic journey, he has gained substantial knowledge in areas ...

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 engineering egg heads at automotive OEMs. Getting the spark plug ...

In a world dominated by pistons, the rotary engine was something different for motorists. It was the vision of German engineer Felix Wankel, built on the belief that the up-and-down motion of pistons ...

Over-the-top rotary builds are an enthusiast tradition. Because so few rotary cars have been made, the limits of the engine type haven't been fully exploited by automakers. It's been tuners who have ...

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 ...
