Europe is miles ahead of us in clean diesels.

You could be behind my volkswagen and not know it was a diesel if not for my "yes, it's a diesel" license plate frame.

having sat behind a diesel bus, there is nothing clean about diesel

Hello? We're currently using high sulfur diesel fuel, not the clean diesel that can be obtained from coal or crude. That's changing this year, and by October we will be using ultra low sulfur diesel nationwide (<15 ppm sulfur).

This will allow for particulate traps and catalytic converters on diesels.

Besides that, the nastiest pollutants are the ones you can't smell.

Well, the diesel fuels and motors used in typical trucks and buses are generally pretty nasty, especially when operating at non-optimal RPM, i.e. accellerating.

However, a diesel engine burning dimethyl ether - which can be synthesized from coal - at optimal RPM - such as in a properly designed hybrid, produces much less pollution than almost any gasoline engine.
