Watch what happens inside a rotary engine

Since it looks like Mazda may very well revive the Wankel rotary engine as a range extender for electric cars, there's no better time to become reacquainted with the quirky internal-combustion engine. And there's hardly a better way to become reacquainted than by peering into a running rotary engine, which you can do with the video above. The video comes to us from the YouTube channel Warped Perception. The channel has already shown what happens inside a conventional internal-combustion piston engine by putting a clear cylinder head on top of a flathead engine. This new video shows off the rotary engine by adding a clear side to a tiny model-airplane engine, something that we weren't aware existed and are glad to know about now. Despite the tiny size, the engine is functionally almost exactly like the bigger versions you'll find in Mazdas from about 1967 to 2012. It has intake and exhaust ports on the edges of the rotor housing, and the triangular rotor swings about in a peanut-shaped housing. For maximum effect, jump to right around the 7:40 timestamp. This is the point at which a bit of acetylene is added to the air-fuel mix for a brighter flame. It's at this point that you can really see when the mixture combusts and how the pressure of the flame pushes the rotor to produce rotational motion. Each stage of the video does slow things down to make everything as clear as possible. Even if you already knew how rotary engines worked, it's still fascinating to watch, first because it's something you don't get to see usually, and also because of the engine's elegant simplicity.

Mazda's first profit in five years in sight due to weak yen

Automotive News reports Mazda is set to turn a profit for the first time in five years. The automaker is more dependent on exports from Japan than other automakers based in that country, and as a result, it has long suffered at the hands of a strong yen. But the currency has declined in value by some 16 percent over the past six months and Mazda's shares have tripled in value to their highest level since 2008. Contrast this situation to a year ago when Mazda printed 1.22 billion new shares to raise cash. The move was equivalent to 70 percent of the company's then-outstanding stock, and values tumbled to record lows as a result.
Now that the yen has fallen to a value of around 96 per dollar, Mazda operations in the US are more profitable and the company now projects it will earn around $279 million for the next fiscal year. Automotive News says a one yen change against the dollar can have a 9.1 percent impact on Mazda operating profit compared to 4.7 percent at Subaru parent Fuji Heavy Industries or 3.1 percent at Toyota. Those automakers better insulate themselves from currency fluctuations with overseas manufacturing facilities.
