The Ministry of Environmental Protection recently issued the "Announcement on the Implementation of National Phase IV Standards for Vehicle Combustion Engines and Vehicle Pollutants Emissions" (hereinafter referred to as the "Announcement"). It is clarified that the vehicle compression ignition engine was implemented on July 1, 2013. National IV emission standards.
We believe that the upgrading of commercial vehicle emissions will bring tremendous development opportunities to the relevant upstream parts and components market.
As the commercial vehicle country III upgrades to the State IV, it is necessary to upgrade the fuel injection system and install an exhaust gas after-treatment system. It is expected that after the full implementation of commercial vehicle IV emission standards, the fuel injection system will add 9.5 billion yuan of market space, which is 85% more than the current fuel injection system market space. At the same time, the new exhaust gas aftertreatment system has a market space of 140 100 million yuan.
Specifically, the in-line pump fuel injection system widely used in Phase III of the country cannot meet the requirements of China IV for fuel injection systems. Electronic control pump nozzles, electronic unit pumps, high-pressure common rail systems, and WAPS systems developed by Weifu Hi-Tech have all Can meet new requirements. Due to cost, capacity, feasibility and other reasons, high-pressure common rail system has the most potential for wide application, and it is also a common technical route adopted by medium and heavy-duty diesel engine manufacturers in China.
In terms of exhaust gas aftertreatment, SCR and EGR+ (DOC/POC/DPF) technologies have their advantages and applications are applied abroad. Comparing the advantages and disadvantages of SCR and EGR+ technology, and considering China's national conditions, we believe that medium- and heavy-duty commercial vehicles will adopt SCR technology, while light commercial vehicles will have a greater possibility of adopting EGR+ technology.
Investment advice: Weifu Hi-Tech will be the biggest beneficiary of commercial vehicle emission upgrades. The company and the participating companies are among the largest suppliers of diesel fuel injection systems in the country. Among them, the joint-stock company Bosch Automobile Diesel is one of the largest suppliers of high pressure common rail fuel injection systems for diesel engines in China.
