Scientists are exploring a surprisingly simple way to clean up diesel engines: adding tiny droplets of water to the fuel. During combustion, the water rapidly vaporizes, triggering micro-explosions that improve fuel mixing and lower combustion temperatures. Studies show this technique can slash nitrogen oxide and soot emissions by more than 60% while sometimes even improving engine efficiency. Because it works in existing engines without redesign, it could provide a quick path to cleaner diesel use.
