There are multiple factors that contribute to soot from diesels. Some of it is the high amount of sulfer. Some of it is from diesel fuel being injected into the cylinder during the compression stroke which doesn't give it a chance to mix as well with the air causing a less controlled burn resulting in more particulates.
I'm not sure about laws about sulfer levels, but I do know that there are new emmission laws that started last year that require emmissions to match those of gasoline. But it's a gradual phase in plan. -Kevin On 4/27/05, Aaron Rouse <[EMAIL PROTECTED]> wrote: > Does the amount of soot coming out of the vehicle differ on what > grade/quality diesel is ran?
