A recent news clip showed that the city of Paris (fr) banned 1/2 the cars to get smog under control. Good thing it worked.
Here is the link: http://www.theguardian.com/world/2014/mar/17/paris-stops-car-ban-one-day
Two short clips from it is:
I am also under the strong assumption that diesel is the preferred motor fuel over there while in the US Gasoline is.
If Paris had cars that used gasoline primarily, how would this be different?
I know in the US where you are required for emission inspection, usually, if not always diesels get off easy, and sometimes have no requirements. I also know that there is this comparatively new line of ‘clean diesels’ - which I know very little about. I also know that so much has been done to reduce emissions from gasoline cars, including the catelitic converter, oxygenated fuel ect.
So would a city environment, such as Paris, fair better with a primary fuel of gasoline? Expanding that is gasoline a better motor fuel for congested mega cities with air pollution issues?
