    Just been reading about how clean the new diesel engines are and I was thinking is this just hype or are they much cleaner than they used to be?

    What does water injection actually do?

    I've been wondering about water injection. People add it to their projects, but what does it do? Surely water doesn't mix well with fuel or even burn? I can see why you'd spray it on an intercooler for example but why on earth would you inject water into your engine?
