Evaluation/improvement of in-cab air quality at an interstate travel center with truck stop electrification

Abstract

This paper presents the results of a study conducted in 2004-2005 related to the measurement of ambient air quality and Heavy Duty Diesel Vehicle (HDDV) cabin air quality in the vicinity of a major interstate travel center in which truck stop electrification (TSE) had been installed to reduce idling of heavy duty diesel truck emissions in a section of the travel center. The paper provides 1) a summary of the ambient air quality (PM2.5, NO X and CO) in the vicinity of the travel center which contains approximately 225 HDDV parking spaces, including both TSE and non-TSE parking spaces 2) the results of a study that was conducted to compare the HDDV cabin air quality (PM2.5) to that of the ambient air under various truck idling operating conditions, including idling, idling with the truck's heating ventilation air conditioning (HVAC) system on external air circulation, idling with the truck HVAC on Max AC with internal air circulation, and no idling with the truck utilizing TSE, and 3) improvements in cabin air quality achieved by installing a more efficient filter medium in the HVAC system of the TSE system.
