Title: Evaluation of technology to support a heavy-duty diesel vehicle inspection and maintenance program.

Principal Investigator / Author(s): Clark, Nigel N. & Mridul Guatam

Contractor: West Virginia University

Contract Number: 98-319


Research Program Area: Emissions Monitoring & Control

Topic Areas: Mobile Sources & Fuels, Monitoring


Abstract:

The desire to establish a heavy-duty I&M program in the State of California is to support the California State Implementation Plan, measure M-17, “Further Emissions Reductions from Heavy-duty Engines.” The thrust is to identify gross emitters, particularly high NOx emitters, and hence reduce their contribution to the emissions inventory, leading ultimately to improvements in air quality. Objectives of this study included identification of a suitable system that would both identify high emitters and realistically quantify emissions from in-service vehicles (System 1) and of a suitable system only for detection of gross emitters (System 2).
