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.
