摘要
OBD技术和车辆排放召回制度在欧美等一些发达国家已成为控制汽车排放污染的有效手段。随着我国汽车排放标准的不断加严,我国对OBD技术和车辆排放召回制度的研究、论证以及引入工作已经开始起步。从2005年开始,中国汽车技术研究中心开始承担国家环保总局与日产汽车公司的合作项目“OBD技术与在用车排放管理研究”,作为该项目的部分研究内容,本论文的主要工作就是通过查阅国内外相关的资料,并借鉴国外的实施经验,对OBD技术和车辆排放召回制度进行深入的研究,从而为我国OBD技术的引入和车辆排放召回制度的制定与实施进行前期的探索研究工作。
     本文首先对OBD技术和车辆排放召回制度进行了概述,简要介绍了OBD系统的功能及意义、排放召回制度的定义和目的以及它们各自的发展情况。然后分别对OBD技术和美国排放召回制度进行了系统深入的研究。对于OBD技术,主要从OBD系统的软硬件组成、排放监测原理和OBD技术与在用车排放控制三方面进行了论述,指出了OBD技术是在用车排放管理的重要技术手段。本文以美国为例对车辆排放召回制度进行了研究,系统地介绍了美国排放召回制度的法律依据和管理机构,重点剖析了排放召回制度在美国的运行机制,并以美国环保局公布的年度排放召回总结为依据,对造成车辆排放召回的原因进行了详细的归类和分析,从而为我国将要实施的车辆排放召回工作提供了大量可借鉴的排放缺陷召回案例。通过上述对美国排放召回制度的深入研究,并结合我国的汽车排放管理现状,从排放召回的制度建设要求、管理建设要求、基础设施要求以及召回制度对汽车、石化、维修等相关行业的挑战四个主要方面对我国实施排放召回制度的可行性进行了论证。最后,概述了我国现行排放管理的全过程,并在上述研究的基础上,为我国汽车排放管理的进一步改进和完善提出了引入I/M制度、OBD技术和车辆排放召回制度等一些有益的建议与对策。
OBD technology and vehicle emissions recall regulations have become the effective means of vehicle emissions control in some developed countries, such as Europe and the United States. With the continuous tightening of vehicle emission standards in our country, the work which research, evaluation as well as introduction of the OBD technology and emissions recall regulations has been started. Since 2005, China Automotive Technology and Research Center has begun to undertake "Research on OBD Technology and In-Use Vehicle Emissions Management" which is the cooperation project of the State Environmental Protection Administration and Nissan Motor Company. As part of the research project, the main task of this paper is to carry on a thorough research to the OBD technology and vehicle emissions recall regulations by consulting the relevant information at home and abroad and learning from foreign implement experiences, thus carry on early exploration and research work for the introduction of OBD technology as well as the formulation and implementation of vehicle emissions recall regulations.
     Firstly, this paper makes a outline to the OBD technology and vehicle emissions recall regulations and it simply introduces the function and meaning of OBD system,the definition and purpose of the emissions recall regulations as well as their respective development circumstances.Then, it carries on a systemic and thorough research to the OBD technology and American emissions recall regulations. For the OBD technology, it elaborates mainly from three aspects, such as, the software and hardware components of OBD system, emissions monitoring principles as well as OBD technology and In-Use vehicle emissions control, and pointing out that the OBD technology is the important technological means in the management of In-Use vehicle emissions. This paper takes the United States as an example to study the vehicle emissions recall regulations, systematically introduces the legal basis and management structure of American emissions recall regulations, analyzes the operational mechanism of American emissions recall regulations with emphasis, and it carries on the detailed classification and the analysis on the reasons which caused the vehicles to be recalled basing on the annual summary of Emission-Related recall which announced by the EPA, thus providing a lot of emissions defect recall cases which can be referenced by the emissions recall work of our country in the future. Through thorough research on the above American emissions recall regulations, and combining with the vehicle emissions management status of our country, it demonstrates the feasibility to enforce emissions recall regulations in our country from four main aspects, such as, regulation requirements, management requirements, infrastructure requirements as well as the challenges to the automotive, petrochemical, maintenance and other related industries. Finally, it outlines the whole process of our country's current emissions management, and on the basis of the above research, proposes that introducing some beneficial suggestions and the countermeasure, such as the I / M regulations, the OBD technology and vehicle emissions recall regulations for the further improvement and the consummation of our country's vehicle emissions management.
