...wrong again guys!..EGR adds octane(slows the burn in the chamber by introducing burnt exhaust gas molicules that slow down the speed of the flame front thru the cylinder).Hot or cold gas will do this...most 'new generation' engines are now using 'cold egr'....Definition...Octane ,in any form...cold air...damp air...egr...high octane fuel additives ALWAYS SLOW THE BURN TO PREVENT DET!...Basic 'combustion engineering'....dig out the thermodynamics text books guys ...do some reading!TH
