Diesel's Dual-Fuel Future

Taking care of emissions in-cylinder, where it belongsOne of my goals working here at Diesel Power is to investigate and help spread the latest diesel innovations that'll soon give us all clean, self-sufficient, renewable power. Efficiency, cleanliness, and maximum performance are not at odds with each other, rather they are the results of complete and controlled combustion. Remember the chemical formula for combustion you learned back in middle school? Me neither, but I do remember it was simple-when the reaction gets crazy, that's when you see the NOx and particulate matter (PM). Engine designers have struggled to make the fire inside the engine do what they want, and when they settle on good enough, that's when we get aftertreatments (afterthoughts), smog (PM), acid rain (NOx), ocean acidification (excessive amounts of carbon from underground), and extremely complicated broken-down engines with massive part counts.

I read that article in Diesel Power as well! Very interesting approach to cleaning up the gases in the cylinder, and not post treating them. One thing that popped in my head was precombustion. I know that the software wouldn't allow it to happen with an all stock engine, but if one were to get the boost pressure high and hot enough, that could become an issue. I guess at that point your not concerned about emissions though.
