Mazda patents show rotary engine for range-extended EV

Two years ago, Mazda introduced a fascinating range-extended electric car called the Mazda2 RE Range-Extender. It took an electric Mazda2, and dropped in an itty-bitty 330cc rotary engine. It wasn't the rotary-powered sports car we had hoped for, but it seemed like a unique way to keep the quirky engine alive and kicking. But not long after the car's reveal, it seemed to disappear. Now the basic idea has resurfaced with a few modern updates in a couple of US patents. The first patent is pretty straightforward and describes a range-extended EV similar to the BMW i3. At the front is an electric motor driving the front wheels. At the back is an internal combustion engine that powers an electric generator. In the middle is a lithium-ion battery for storing and delivering electricity. It's the same set-up as that Mazda2. The second patent is for an engine start-and-stop system, but specifically for rotary engines. The system is designed to shut off a rotary engine when not needed, much as modern piston engines do. It also stops the rotor in a position that closes the intake port to ensure no fuel or exhaust emissions slip out through the intake tract. This is necessary since there are no valves in a rotary, and air and exhaust come through ports that are "opened" and "closed" by the rotor itself. The patent also describes the possibility of firing a spark plug after the fuel has been cut to eliminate any leftover fuel emissions. This system would theoretically improve a rotary engine's fuel economy and emissions significantly, which would be a boon as those are two of the rotary's major weaknesses. The rotary-engine patent also includes the same range-extended powertrain drawing as the first patent. It's there as a description of a possible application. And in such an application, where the rotary wouldn't have to run all the time, the system could take advantage of the rotary's inherent strengths. Weight can be kept low thanks to the engine's small dimensions, which should help in keeping the car sprightly and efficient. Rotaries are renowned for smoothness, too, so it shouldn't need too much refining and sound deadening, the latter of which adds more weight. The small size would also help with packaging, leaving more space for people, cargo, or possibly batteries. And since it has been patented, the company may be looking to bring the system to market.

Illinois’ pro-union stance kills bid for Toyota-Mazda plant, report says

Mazda and Toyota are fielding bids from states eager to land its new prize: an all-new $1.6 billion U.S. plant where the Japanese automakers would jointly build electric vehicles and employ around 4,000 workers. Now we can apparently scratch Illinois off the list of contenders. According to Automotive News, the Land of Lincoln has been disqualified due to a lack of shovel-ready sites and the state's lack of a right-to-work law curtailing union membership. Mark Peterson, the president and CEO of economic development agency Intersect Illinois, told the publication he's been informed Illinois is not among the three or four finalists for the facility. It's believed those finalists are all in the South. Peterson said that "many national site consultants charged with making recommendations for corporate relocations and expansions will not even consider a state that is not a right-to-work state. In this case, the three states I am told are still in the running are all right-to-work states." The Midwest may be the ancestral home of U.S. automotive manufacturing, but the South has made major inroads in recent decades, with the likes of Honda, Mercedes-Benz, Nissan and Toyota all opening plants there, among others, thanks to lucrative tax incentives and the absence of labor unions. Recent years have also seen so-called right-to-work laws, which prohibit union dues and membership as a condition of employment in organized workplaces, spread to traditional labor strongholds such as Michigan and Wisconsin. The new joint venture plant, which would start operating in 2021, would be capable of producing 300,000 vehicles a year, with production divided between the two automakers. Mazda and Toyota would also take small stakes in one another as part of the deal. It's expected that at least 15 states have submitted proposals to attract the plant. Expect the Illinois news to trigger a new round of debate over the role of organized labor in the modern economy.Related Video: Image Credit: Reuters Green Plants/Manufacturing Mazda Toyota
