Love their innovation!

We love ourselves a good oddball engine, and tiny, scrappy Mazda certainly must be responsible for more such engine concept patents per market-capitalization dollar than any other. We just discovered the automaker's name on US 2022/0034265 Al, dated February 3, describing a supercharged two-stroke engine that dials up the degree of engine-control difficulty another few notches by operating as a compression-ignition (like a diesel) under low loads, and spark ignition during high loads. If that last part sounds familiar, it's because Mazda employs it on its Skyactiv-X engine not yet sold here in America.
