I applaud Mazda for their ongoing focus on KISS. Instead of trekking down the hybrid path and making cars that are complex, heavy and, down the road, maintenance and disposal nightmares . . . let's take what works and improve it.
The piston dome design seems counter-intuitive to me. I can see that it would contain part-throttle ignition in a localized area, but it looks like a flow nightmare, especially during the cam-lobe overlap region at TDC of the exhaust stroke. I suspect these engines are being designed with very little overlap.
I'm surprised to see that they are not using direct injection. That seems like an excellent way to control knock.
It is cool that they are coming up with a relatively common design for their gas and diesel engines. Accountants must be happy with that.
Looking forward to the ND's. Of course, all of this new technology and 14:1 CR's means that it will be that much harder to mod and tune. You could really blow stuff up quickly.
