国六轻型汽油车技术特点和使用建议

Technical Characteristics and Use Recommendations of the CN6gasoline Light Duty Vehicle

随着国六标准在东部和沿海城市的提前实施,市售车辆已经逐步切换为国六车.本文阐述了国六法规的制定背景和实施进程,从法规变化对车辆的影响、法规对发动机和后处理系统的影响、法规对用户的影响几个角度对国六车辆的技术特点和使用特性进行了阐述.并重点介绍了汽油颗粒捕获器(GPF)的应用特点、应用领域、系统布置和工作特性,涂覆催化剂的GPF,能够提高GPF的过滤效率,且部分替代三元催化剂的功能,GPF的使用也能够满足未来严格颗粒物排放的法规要求.在文末对用户的日常使用提出了建议.

With the implementation of the CN6LDV emission Standard in the eastern and mega cities,vehicle in the market have gradually switched to the CN6.This paper describes the background and implementation process of the CN6 regulations,including the impact of regulatory changes on vehicles,the impact of regulations on the engine and after treatment system,the impact of regulations on users,etc.The application characteristics,application fields,system layout and working characteristics of the gasoline particle trap(GPF)are mainly introduced.The coated GPF with the catalyst can improve the filtration efficiency of the GPF and partially replace the function of the three-way catalyst.At the end of the article,suggestions are made for the daily use of the user.
