EFFECTS OF FUEL TYPE, DRIVING CYCLE, AND EMISSION STATUS ON IN-USE VEHICLE EXHAUST REACTIVITY

The introduction of reformulated gasolines greatly reduced exhaust hydrocarbon (HC) mass emissions, but little data is available concerning how these new fuels affect exhaust reactivity. While it is well established that high-emitting vehicles contribute a significant portion of total mobile source HC mass emissions, it is also important to evaluate the exhaust reactivity from these vehicles. The aim of this study was to evaluate the relative influence on in-use vehicle exhaust reactivity of 3 critical factors: fuel, driving cycle, and vehicle emission status. 19 in-use vehicles were tested with 7 randomly assigned fuel types and 2 driving cycles: the Federal Test Procedure (FTP) and Unified Cycle (UC). Total exhaust reactivity was not statistically different between the FTP and UC cycles, bus was significantly affected by fuel type. Additional results are presented and discussed.
