I wonder how lovering the compression ratio of the engine will affect the emission of NOx. As far as I know a compression ratio of 15-17 is the most efficient for a diesel engine. The reason for using the 20- 24 compression used in cars today is to make them easier starters. I guess a lot of engines could be run more effectively, at least those engines that doesnt have to do cold-starting. Is this wrong? (But then, should the timing be altered, and how much? John, DK
