Twenty Heavy Heavy-Duty Diesel Trucks (HHDDT) and Medium Heavy-Duty Trucks (MHDT) were characterized for emissions in Phase 2 of the E-55/59 program. Project E-55/59 Phase 2 (E-55/59-2) had the objective of acquiring regulated emissions measurements from nineteen in-use trucks in southern California, and supporting a third-party characterization of non-regulated species from five HHDDT and one diesel - fueled MHDT trucks (total of 6) in the Phase 2 test fleet. Non-regulated exhaust characterization included speciation of both particulate matter (PM) and volatile organic compounds (VOC), and determination of particle size distribution. In addition, one vehicle (E55CRC- 45) was found to have a defective solenoid for the fuel pump. This vehicle was repaired and re-tested. A twentieth vehicle was added to the study when difficulties were encountered in testing a 2002 model year truck (E55CRC-52) on the medium-duty chassis dynamometer.
