Heavy-Duty Engine Exhaust Particulate Trap Evaluation

摘要

This report describes a laboratory effort to evaluate several aspects of the use of exhaust particulate traps with heavy-duty diesel engines. The effort involved: monitoring exhaust temperatures in heavy-duty vehicles operating on a chassis dynamometer; design and evaluation of a particulate trap bypass system; regeneration of particulate traps; and exhaust emissions evaluations of a heavy-duty diesel engine, with and without exhaust particulate traps.
