一、概述1、最近的发展趋势及对其要求汽车保修设备的发展经历了从修理工具到近代化的诊断装置这样一个过程。最近,对保修设备提出的要求是:防止公害、省力、安全和经济。对汽车运行过程中产生的公害采取的措施是,限制现在正在使用中的汽车怠速时排出的一氧化碳的浓度。另外,从1975年1月开始,还特别对碳化氢(CH)和柴油机烟度作了限制,在“公路运输车辆的安全标准”部分修改后予以实施。
First, an overview 1, the recent trends and requirements of its development of car warranty equipment has gone from repair tools to modern diagnostic device such a process. Recently, the requirements of the warranty equipment are: to prevent pollution, labor-saving, safety and economy. The measure taken for the pollution that occurs during the operation of a motor vehicle is to limit the concentration of carbon monoxide that is emitted when the car is currently idle. In addition, since January 1975, restrictions on hydrocarbon (CH) and diesel engine smoke have been given, in particular, and they have been implemented after the revision of the “Safety Standards for Road Transport Vehicles” section.
