Diesels challenge hybrids for efficiency, low emissions More of an engineering magazine, I added my comments to their thread after someone suggested auto-stop the diesel. Enjoy, Bob Wilson
Micro-hybrid would have very limited regen brake and it can't crawl through traffic jams without a burst of combustion. How about A/C? The diesel engine will need to run then. For emission, NOx is a couple of order of magnitude higher than a full hybrid with Atkinson cycle ICE.
