Thanks, pre mixed air/fuel before ignition.Found another writeup, gives a bit more clarity.

Thanks, pre mixed air/fuel before ignition.
How that is achieved mechanically will be interesting. I still think the intake valve will be eliminated in new engines and all air pushed through with fuel premixed.
That is based on how it works today. This is a new way. We can agree to disagree, but if the intent is to mix fuel and air which this is, then it needs to be premixed on input, unlike it is done today. If air is already in there, then it has not gone through the Bunsen burner inspiration. Time will tell.Based on how diesels ignite their fuel, that's not a viable option. In a compression ignition engine you can't inject the fuel until right when you're ready to light it, so at least most of the air already needs to be in there and compressed.
The BOI/EOI event is really where it would help as at those points the injection pressure is lower than ideal, causing dropout of the liquid fuel.
As someone whose job entails selling and servicing "large, million dollar" locomotive diesel engines in marine and power generation applications I look forward to a manufacturer trying this out.
This week I had to replace some SCR bricks in a USEPA Tier 4 diesel, and the dry PM that accumulates in the SCR housing creates quite a mess...gives a good visual on what is really emitted from the tailpipe.
Ski, I get how it works now.
I do not get how the fuel is prevented from igniting at the intake end of the tube before the fuel/air is mixed out the other end.
Heh, got a glossary for that alphabet soup? SCR, BOI, PM, USEPA?
