   Yes, ran into an article on diesels.  Partly polution related (very   
   slanted) but it did mention that they don't do well on idle.  The   
   fellow was recommending a law that diesels not be allowed to idle more   
   than some short time (2 minites?  We have lights longer than that   
   here).  They wanted them to turn it off then restart.  Problem came up   
   that that costs more gas than idling.
