Cool.

...Ducted fuel injection for diesel engines, developed at Sandia National Lab’s Combustion Research Facility by Charles Mueller, can fine-tune the fuel-air mixture in an engine to the point of eliminating between 50% to 100% of the soot typically generated by diesels. “And engine manufacturers are starting to show excitement about it,” he says. Manufacturers like it because it cleans up the emissions, it work well with conventional diesel fuels, and it is conceptually simple and can be built from low-cost materials.

“Ducted fuel injection could also be retrofitted onto existing engines,” Mueller says. “This is especially important for large engines, such as those used in ships and locomotives where the engines can cost $1 million or more and converting to all-electric power is cost-prohibitive. A retrofit would be relatively inexpensive and could provide substantial emissions benefits right away.”...

thanks! very interesting for sure + just what may be needed to bring more fuel efficient diesels into smaller cars + pickup trucks. diesel is king in europe but fuel subsidies surely help.

It would be a huge benefit if it can help eliminate some of the problem prone emissions equipment that is currently on 07 and newer on-road diesel engines.

There's gotta be more to this than merely a tweak on a direct injector design to include a 'duct'.

Or maybe it really is that simple. And for just the price of a new set of (direct) injectors...

I'm inclined to think that the OEMs would jump as fast as they possibly can at this, if it means they can delete or even significantly reduce the soot mitigation equipment they now have to install....


Change your thinking...not your oil!
Turn your mind....not your rotors!

If it's as efficient and easy to install as it sounds, it could really save a lot of money and and time, especially in fleet applications.
