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 helps coronavirus fight with free oil changes for all healthcare workers

During the hard times caused by the coronavirus pandemic, automakers are helping any way they can, big or small. Mazda is one of those offering support specifically for the nation's healthcare workers who are risking their own lives in order to save others. Mazda calls it the Essential Car Care Program (ECCP), and it offers free upkeep to any healthcare workers with a car, not just a Mazda. Through the ECCP,  Mazda is offering healthcare workers free oil changes and "enhanced cleaning services." The program begins April 16, 2020, and will run through select participating dealerships. To repeat, this is not only for people who drive Mazdas, it's for anybody working in healthcare. Mazda says it is "available for most makes and models from other manufacturers," excluding exotics, classic cars, off-road vehicles, and vehicles that take more than eight quarts of oil. The offer is available for service on one car per program period. The program, for which Mazda will donate a minimum of $5 million, was inspired by Mazda dealerships that independently offered similar perks to local healthcare workers. Those eligible for free services include anybody who works at the following facilities:   Hospitals, urgent care, surgical centers, birth centers Healthcare providers, doctor offices, medical clinics, medical offices, medical centers, medical facilities, health systems Mental health providers, addiction treatment centers Assisted living, long-term care facilities, nursing homes, hospice homes, adult care homes, home health agencies Public health agencies Medical laboratory and research centers Medical equipment providers Orthopedic and other rehabilitation centers including physical therapy and chiropractic Blood banks Telehealth providers All workers need to do is show proof of occupation, and they're in. In addition to the oil change, the enhanced vehicle cleaning will use EPA-approved cleansers on high-touch interior surfaces, as well as exterior surfaces.  The ECCP runs through May 4, 2020.

Airbag recall widens to include BMW, Chrysler, Ford and Toyota

The recall of faulty airbag inflators supplied by Takata has exploded today to grow to seven automakers. In most cases, only models in certain high-humidity regions were affected because the National Highway Traffic Safety Administration found in its investigation that moisture played a roll in determining whether there would be a problem. However, some companies opted for national campaigns. The exact number of affected models for these campaigns isn't yet known at this time.
BMW is recalling an undisclosed number of 325i, 325Xi, 330i and 330Xi models from the 2001 through 2005 model years and the 2001-2006 model year versions of the 325Ci and 330Ci for the driver side and passenger side inflators. Only vehicles currently registered in Florida, Puerto Rico, Hawaii and the US Virgin Islands are covered under this recall.
Neither Chrysler's filing with NHTSA nor its press release list the specific models affected, but a company spokesperson told Autoblog that at this time it only covers the driver and passenger side inflators for the 2006 Dodge Charger in Florida, Puerto Rico, Hawaii and the US Virgin Islands
