Diesel vs Gasoline Myth

3108 Views 9 Replies 5 Participants Last post by  tugboat
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.

Competing information here. Do we know which of the studies are correct? Seems weird that all the sudden we discover something that we thought was better for the environment ends up being 1000 times worse.

Whatever is the truth, it won't matter really. It doesn't seem like American culture is affected much by scientific fact.
