Evaluating real-world idle emissions from heavy-duty diesel vehicles.

摘要

Long haul trucks in the USA idle for extended periods at truck stops and at pickup and drop-off points. The idling consumes fuel, contributes to engine wear and reduces atmospheric quality, but it cannot simply be proscribed because in many cases cab heat or air-conditioning provides essential driver comfort. As an example, there are nearly 1.5 million interstate trucks that operate in California, where climate control is essential. A comprehensive tailpipe emissions database to describe idling impacts is not available at present, although studies have been conducted to quantify idle emissions and to project the advantages of idle reduction technologies based on a few vehicles. This thesis presents one of the most complete data set available that may be used to quantify the impact of future idle reduction programs, and incorporates results from the West Virginia University transient test cell, the E-55/59 Study and the Gasoline-Diesel PM Split Study.
