Study of Aftertreatment and Fuel Injection Variables for Particulate Control in Heavy-Duty Diesel Engines

摘要

This report summarizes the results of a multiyear project funded by the Environmental Protection Agency (EPA) to provide data on the impact of engine operating parameters, fuels, and exhaust aftertreatment devices on the physical, chemical and biological character of diesel particulates. These data are useful for determining whether various control technologies can minimize the health and welfare impact of diesel particulates on society. Two main studies are emphasized: (1) the results of varying fuel injection parameters and (2) the evaluation and characterization of available (current technology) as well as aftertreatment devices, including catalysts and particulate traps. A brief study of an adiabatic engine is also exaimed.
