According to the "China diesel EGR System Market Research and future forecast report (2018 Edition)" released by Limu information consulting, although there is still a big dispute on the contribution of vehicle emission pollutants to the haze weather spreading across the country, it is certain that the Chinese government has started to take measures to control this pollution source - from January 1, 2017, the fifth stage of national motor vehicle pollution The emission standard was officially implemented.

The increasingly stringent vehicle emission standards have promoted the rapid development of the automotive exhaust aftertreatment system industry. In 2012, China's diesel EGR market installed 520000 units, and by 2016, it increased to 1.37 million units. With the gradual strengthening of the implementation of environmental protection policies in the future, the relevant exhaust gas aftertreatment systems will increase accordingly. It is estimated that by 2021, the installed capacity of China's diesel EGR market will reach 1.94 million units, compared with 20 The average annual compound growth rate of 16 years was 7.21%.

In the field of diesel EGR, lonson technology, borgwana, Rheinmetall automotive and Yibin TIANRUIDA have occupied the main market shares, accounting for 31%, 30%, 24% and 5% respectively. Longsheng technology product line covers all aspects of EGR system, including pneumatic and electric EGR valve products adapting to national emission standards, ECU control unit suitable for non road diesel engine, industry-leading tubular and plate fin EGR coolers, and supporting pressure, temperature and gas sensors.
