At the same time, some sub-sub-sectors such as TPMS, tail gas treatment and automatic transmission have the possibility of outbreak of demand in the medium term and may be properly concerned.
First, TPMS
That is, the tire pressure monitoring system, the airbag and the ABS constitute the three safety systems of the car, which can effectively reduce the risk of the tire burst. Since the introduction of the TPMS in the 1990s, the TPMS has gradually infiltrated downward from high-end models, but at present, The rate is still low. "Passenger Car Tire Pressure Monitoring System Performance Requirements and Test Methods" (GB26149) after the adoption of all new certification since January 1, 2019 passenger vehicles and from January 1, 2020 onwards all passenger cars will be mandatory Install TPMS. Reference to the United States, the European Union and other regional experience, mandatory installation policies or will usher in the domestic demand for TPMS ushered in. Wantong predicts that the TPMS new car assembly rate will rapidly increase from 20% in 2015 to over 60% by 2020, and the market demand will rise from 18.2974 million in 2015 to more than 100 million.

Second, exhaust treatment
According to the regulations, the scope of implementation of the CW5 standard will be extended to heavy-duty diesel vehicles starting from July 2017 and will be expanded to light-duty diesel vehicles starting next year. Compared to the national standard IV, the emission limits of nitrogen oxides, non-methane hydrocarbons, particulate matter and other pollutants in the five diesel engines of China decreased from 0.25g / km, 0.3g / km and 0.025g / km to 0.18g / km, 0.23 g / km, 0.0045 g / km. In the past, diesel engines were improved to reduce pollutant emissions by enhancing turbocharger intercooling, multi-valve technology, exhaust gas recirculation and cooling, and electronically controlled high-pressure injection systems. However, as emission standards are being improved, exhaust aftertreatment technologies have met the standards, and related products Demand will increase. Taking DPF (particulate matter trap) as an example, the filtration efficiency of DPF and wall-flow DPF in exhaust gas can reach 40% -60% and 80% -90%, respectively, and will be widely applied after the implementation of national standards However, due to the increasing environmental protection requirements, the installation of DPF has been implemented in some areas on the basis of National Five, and DPFs have been required to be installed on heavy diesel vehicles or diesel vehicles in Beijing (2016), Shenzhen (2017), Tianjin (2017) , The rest of the region is also expected to follow up.
Third, automatic transmission
The penetration of automatic transmissions in the passenger car market continues to increase. It is estimated that the share of auto sales in the domestic sales of manufactured passenger cars increased from 31.0% to 43.2% and the manual transmission ratio dropped from 69.0% to 56.8%. The future of automatic transmission ratio will continue to rise. At present, there is a domestic auto transmission capacity gap, including the public, SAIC, the Great Wall, including the major OEMs and mainstream transmission manufacturers such as ZF, Gertrak, Jetco and so on are expanding in the country, upstream The demand for gear products formed a significant pulling effect.
