随着汽车保有量的日益增加,汽车排放污染已经成为社会日益关注的焦点。在节约资源和保护环境已经定为基本国策的今天,汽车对低碳环保和节能减排方面也提出了更高、更严格的要求。汽车排放污染的治理除了要从汽车设计和制造等源头上进行严格控制以外,更重要的是从汽车日常使用与维护中加以治理。汽车正常地运行可以使各种油料、轮胎和机件等损耗降至最少,相应的排放污染也可控制在最低,而汽车要正常健康地运行就必须依靠正确的维护与修理。目前,我国汽车维修行业节能减排的重大阻碍之一就是现有的检测诊断技术的单一化,使得大部分维修技术人员在 With the increasing car ownership, automobile emissions pollution has become the focus of growing concern in society. In saving resources and protecting the environment has been set as the basic national policy of today, the car on the low-carbon environmental protection and energy-saving emission reduction also put forward higher and more stringent requirements. In addition to strict control over the source of automobile design and manufacturing, more importantly, vehicle emission pollution control should be governed by the routine use and maintenance of automobiles. The normal operation of the car can make a variety of fuel, tires and mechanical parts to minimize wear and tear, the corresponding emission pollution can be controlled at a minimum, while the normal operation of the car must rely on the correct maintenance and repair. At present, one of the major obstacles to energy conservation and emission reduction in China’s automobile maintenance industry is the simplification of existing detection and diagnosis technologies, which makes most maintenance technicians
