It doesn't always cause more smoke, though. If you mix too much in, it doesn't have time to burn fully. The more you mix in, the higher you have to advance the timing. There's a break even point, like with everything, and there there's a point of diminishing returns.

Spark ignited diesel isn't a new concept, it can be executed cleanly, but requires proper tuning, as with any modification.
