Compression ignition gasoline engines
I notice Mazda is going to have a compression ignition gasoline engine that will still have spark plugs for starting and heavy loads. What would be the advantages of such a engine?

NOx emissions are a big problem with compression ignition engines. I wonder if we will see exhaust fluid there too.
Mazda is still using a spark plug as well for finer control over the ignition, it's kind of a hybrid.
Not strictly compression ignition 100% of the time.
They explain how it works and how they control NOx emissions here:

Very interesting stuff. I would love to see if they could make this work with the BMW tech that uses no throttle valve on a gas engine. What kind of efficiency would we be seeing then!
