AI Contract Overview

Show more

The Federal Railroad Administration is seeking research to evaluate how air leakage affects the operations and performance of locomotive automatic engine start/stop systems. The primary objective is to understand the impact of excessive air leakage on the ability of these systems to function as intended, specifically focusing on quantifying the fuel penalties resulting from leaks in the locomotive and simulated leaks in the brake pipe air system. This project aims to build upon previous screening tests by identifying the specific fuel penalties associated with the additional engine runtime required by the automatic engine start/stop system to maintain air pressure in the main reservoir. This research addresses a gap in previous data, which only identified fuel penalties during continuous operation for line haul and switcher duty cycles.

Research to evaluate the effects of air leakage on operations and performance of locomotive automatic engine start/stop (AESS) systems. Understand the impact of excessive air leakage on AESS' ability to operate as intended. This project focuses on quantifying the fuel penalty associated with air leaks on the locomotive and simulated air leaks in the break pipe air system. Previous SwRI screening tests only identified the fuel penalties associated with the line haul and switcher duty cycles during continuous operation but did not identify the penalty associated with the additional time that the Automatic Engine Start Stop (AESS) system needs to operate the engine to maintain the air pressure in the Main Reservoir (MR).
