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.

Crossovers help Mazda post its best January sales in 24 years

Mazda's 2017 ended on a bit of a flat note. It wrapped up the year with 2.8 percent fewer U.S. sales than 2016, and 8 of the 12 months lower month-over-month. But 2018 is off to a much brighter start with the company having its best January sales month since 1994, with just under 25,000 cars sold. Besides that headline statistic, the higher sales also mean this January exceeded 2017's sales by 15 percent or about 3,300 cars and put it ahead of January in that healthy 2016 year. Compared with this past December, though, sales are down about 2,000 cars. The gains are entirely due to the success of Mazda's crossover SUVs. The CX-5 was the best of the best with a month-over-month gain of over 66 percent. In actual numbers it sold about 13,500 copies compared with about 8,000 last January. The big three-row CX-9 had a big jump going from 1,600 units sold last January to about 2,300 for a gain of almost 47 percent. Even the little CX-3 saw a small gain between the two Januarys, going from about 1,200 to 1,350 sales. View 14 Photos Mazda's January would've been even better if its conventional cars hadn't dropped so much. Both Mazda Miata and Mazda6 sales dropped by just over half. The Mazda dropped from 3,300 sales to just under 1,600, and the Miata dropped from a little over 900 to a little over 400. Mazda3 held on a little better with just a 12 percent drop from last January going from about 6,600 to 5,800 sales. The lopsidedness of these sales isn't all that surprising. Crossovers have been a boon to loads of manufacturers. For example, Mitsubishi had an 2017 full of sales improvements, with the company finally breaking 100,000 units for the first time in years, and it was all because of improving crossover sales. January's sales also continue an unfortunate downward trend for Mazda's cars, with both the Mazda6 and Mazda3 having month-over-month declines every single month since February. It will be interesting to see if the new turbocharged engine option on the Mazda6 will improve sales of the sedan later this year. Related Video: This content is hosted by a third party.

Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.
