Abstract

This paper examines the introduction of the NO_x-to-fuel mass ratio in the Euro 7 regulation, a parameter designed to evaluate the effectiveness of the vehicle emission control by assessing the mass of NO_x emitted relative to fuel consumption. This approach has been selected for its potential to identify high-emitting vehicles, which may result from malfunctioning or manipulated emission control systems. This study reviews in detail the methodology proposed by the European Commission for this parameter utilizing data from an on-road Euro 6d-Temp diesel vehicle, anticipating its outcomes within the Euro 7 framework and highlighting some potential limitations.

识别具有nox与燃油质量比的高排放欧7车辆

本文考察了在欧7法规中引入的NOx与燃料质量比，该参数旨在通过评估NOx排放相对于燃料消耗的质量来评估车辆排放控制的有效性。选择这种方法是因为它具有识别高排放车辆的潜力，这些车辆可能是由故障或操纵的排放控制系统造成的。本研究利用一辆欧6d-Temp柴油车的道路数据，详细回顾了欧盟委员会为该参数提出的方法，预测了其在欧7框架内的结果，并强调了一些潜在的局限性。

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
