Automatic Engine Start Stop (AESS) continuation and Air Leak Fuel Penalty Study

FRA) intends to award a sole-source contract to Southwest Research Institute to identify the fuel and emissions penalty of the Automatic Engine Start Stop (AESS) system not being able to keep the locomotive shutdown due to air leaks. This is in addition to the available information on the fuel consu

mption and emissions penalty associated with the addition of a simulated break pipe air leak of 30 and 60 Standard Cubic Foot per Minute (SCFM) as a follow-on requirement to continue work previously performed by Southwest Research Institute
