摘要
通过市场需求分析,独立的柴油车后处理故障诊断系统并不多见,且价格昂贵,在中小型汽修企业的日常检修中使用率不高。从机械、电气、程序三方面进行设计,开发了基于SCR技术的便携式汽车尾气后处理故障检测诊断箱,并通过技术优势和经济社会效益分析,结果表明:便携式汽车尾气SCR故障诊断箱故障定位精准、安全等级高、用户体验快捷,具有巨大市场潜力。
Through the market investigated the independent diesel reprocessing fault diagnosis system is rare and expensive,and its usage rate is not high during daily maintenance in medium and sized enterprises.The design scheme was put forward from machinery,electricity and program,and portable test diagnosis case was developed for vehicle exhaust post treat based on SCR The results of analyzing technical advantages and economic and social benefits showed that the test diagnosis case for SCR has accurate fault location,high safety level,fast user experience and a large market potential with a promising future.
