not really any concerns, just wondering if it is really as innovative as he said. He mentioned something about the design focusing down the air in a different way to reduce the turbo lag
but he didn't describe it very well and the engineer part of my brain is curious about it
I know mazda in general takes a slightly different view to engine design, so it wouldn't surprise me, but the details were a little fuzzy
I have a pretty good idea of how their direct injection and compression ratio stuff works for the combustion side of skyactiv, but my understanding of turbo's is a bit more limited. I get the basic idea, but have never really worked with them so I don't completely get the difference between a typical turbo and what Mazda is doing with their new design
oh, that's interesting, apparently the 2.5T doesn't use the compression ratios for it's efficiency, though it is still direct injecting
here's a relevant article, guess they've been using the design since 2016, not sure if anything's changed in the 2017 or 2018, but it does appear to have the variable nozzle
