Diesel is always the way to go, as higher compression ratio equals  
higher efficiency.  Dugald Clerk wrote about it more than one hundred  
years ago.  Clerk actually stated in one of his books that although  
Diesel was on the right track by experimenting with high compression  
engines, Diesel still didn't know WHY high compression was better,  
and that he didn't understand the thermodynamics involved.  SMACK!   
Ya think there could have been a little rivalry among engine luminaries?
