Evaluation of On-Road Results from a Test Fleet of Heavy-Duty Trucks

New and upcoming regulations for heavy-duty diesel (HDD) on-road vehicles are expected to provide significant reductions in the emissions from newly purchased HDD vehicles. CARB has conducted several pilot studies to understand the incidence of malmaintenance.and tampering in HDD vehicles and to develop a program to control emissions from in-use trucks. The objective of the current program was to collect in-use, on-road emissions measurements on five vehicles in the Stockton, CA area. Emissions measurements were made with the University of California at Riverside's Mobile Emissions Laboratory (MEL), which is mobile measurement platform with a full dilution tunnel. The results of this study provide information about emissions from in-use HDD vehicles under typical driving conditions and can be used to better understand emissions inventories and in the development of regulations for in-use vehicles.
