I saw this in Hemming Motor News weekly blurb...

Its stock in trade, as the title implies, is historic automobiles, but Hemmings Classic Car throws its readers a little swerve every now and again. In the current issue, November 2009, you can find a biography of Clessie Cummins, who did a lot of great things for both cars and trucks during his lifetime, and for the way they use fuel efficiently.
Clessie would have loved this tidbit that SAE International reported very recently. Cummins was among the first to consistently combust vaporized diesel fuel, which exists as both a liquid and a gas, and thereby poses unique challenges to engines trying to ignite and burn it. Researchers at Syracuse University believe that diesels of tomorrow will apply exhaust heat directly to their incoming fuel, creating a previously unachieved state of matter in which the fuel cannot become liquefied and thus create dirty waste, such as soot. Future diesels will likely ignite their fuel mixtures at up to 30,000 PSI, lowering emissions levels by up to 80 percent - even over today’s “clean” direct-injection diesels.
