Diesel vs Gasoline Myth

there is a long standing assumption that diesel exhaust is worse for the environment and worse for our health than petrol. But what if that was not quite true?

Its come to light recently that engines using Gasoline Direct Injection technology actually emit more small particles than modern diesel engine. Particulates are the little buggers that cause cancer.

GDI is in everything now as a means to bump power, increase efficiency and lower Co2, but this new study claims that GDI engines crank out 1,000 times more harmful particles than traditional petrol engines and 10 times more than modern diesels.

By law diesels are required to be sold with a particulate filter, but petrol plants currently escape the distinction despite the information.

And yet they don't want to expand the amount of diesel vehicles on the road in America. At least the 1500 having a diesel option is one good step in the right direction
It would be helpful to see more information backing this, just to see how credible it is. People seem to usually take stuff like this for it's face value, but we need to look into it more.
I think that one of the reasons why diesels aren't as popular even though they are more efficient and cleaner is that the exhaust they spit out looks dirty. Petrol exhaust doesn't look a dark and has a different smell. Without knowing the background study and just judging by exhaust, sound and smell, I think most people would assume that the petrol is more clean.
I doubt thats an issue, yeah that happens but only Prius owner happen about that and everyone knows the opinions of Prius owners don't matter :D
