In a sense that doesn't count, as much of that 'efficiency' is due to final combustion inside the catalytic converter where it does nothing for propulsion. If you could do anything to make the existing burn more complete, and/or have its pressure curve somehow better shaped for extraction of energy via the piston as it moves over its sinusoidal path, then you would see a gain. > What about propane fumigation of a diesel engine?

I do know that if you're seeing soot you're seeing unburned fuel, so there's room for improvement in the basic diesel process. -- Jim _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
