National Five DPF Trends FAW Xichai takes the lead in completing technology upgrades

In light of the increasingly severe atmospheric environmental pressure, the 5th session of the 12th National People's Congress held the opening meeting at the Great Hall of the People on March 5. When Premier Li Keqiang made the government work report, he pointed out that we must firmly defend the blue sky in 2017. war. The emissions of sulfur dioxide and nitrogen oxides were reduced by 3% respectively, and the concentration of fine particulate matter (PM2.5) in the key areas decreased significantly.

National Five Environmental Protection Regulations

Some big cities are already not satisfied with the national standards of fuel vehicle countries. Five environmental protection laws and regulations: According to the spirit of the “Key Work of Air Pollution Prevention and Control in 2017 in the city” released by the Tianjin Environmental Protection Bureau at the end of February, Tianjin is a municipality directly adjacent to the political center. It is necessary to “resolutely fight for the prevention and control of atmospheric pollution”.

Among them, there are two enhanced governance measures involving the internal combustion engine industry. Article 9: Continuing to accelerate the phase-out of old vehicles and study the implementation of restrictions on the implementation of heavy-duty trucks and state I and State II light-duty gasoline vehicles. Article 10: Carry out special rectification actions on motor vehicle exhaust pollution and install particulate matter traps (DPF) on high-emission heavy-duty diesel trucks.

This is the third city after the Beijing and Shenzhen that explicitly requires that the country must install DPF.

DPF device

First, comprehensive filtration without dead ends, green upgrades are guaranteed

First of all, let us first understand the DPF: the particulate particulate filter (DPF), whose role is to comprehensively capture all particulate matter in diesel exhaust emissions, which is highly efficient and can significantly reduce PM emissions from diesel engines. the amount. The DPF discharge post-treatment technology is currently the most effective PM treatment technology.

Second, the technical advantages of DPF in emission control:

1. Guowu Diesel Engine adopts the “EGR+DOC+DPF” technology route, which can achieve precise control and strictly control emissions. The engine DPF completely captures all the carbon particles in the emissions, and realizes active regeneration under certain conditions. The carbon particles are oxidized to complete the green upgrade and are in full compliance with the stringent requirements of the National V and the Beijing V regulations.

2. As there is no urea involved in the chemical reaction of the exhaust gas, the diesel engine of the DPF technical route has no ammonia emission and reduces the pollution caused by the SCR ammonia emissions.

Second, science and technology governance fog, decision-making manifested

Once upon a time, the Beijing Municipal Government was subjected to a large-scale stumbling block by the industry because of Special Beijing Five's request for the DPF technology route: The industry generally believes that as long as the national five-nation standard is discharged, it can effectively control the haze in China. Although it cannot be said that diesel vehicles are the decisive factor in the formation of smog in China, in recent years, the speed with which the Chinese haze advances south has indeed required encouraging more scientific emission technology routes.

In Europe, the DPF technology route is only used in the Euro 6 emissions phase, so the advanced nature of the technology has become a consensus. Following Beijing, the local governments of Shenzhen and Tianjin stood at the strategic height of livelihood and livability. With scientific and innovative thinking, with extraordinary courage and courage, we enhanced local environmental protection laws and regulations. We should all be Shenzhen and Tianjin. The government likes!

It can be foreseen that more cities will learn from Shenzhen and Tianjin this year, especially in cities with large cities and severe haze. It can be said that the installation of DPF in China's five diesel engines is a general trend and a major market trend!

III. The DPF technology is mature and the emission improvement is guaranteed

Although DPF belongs to Euro 6 technology in Europe, the innovative Chinese internal combustion engine industry has long been engaged in the research and practice of DPF on the National 5th diesel engine. At present, several diesel engine plants have achieved the national Ministry of Industry and Information Technology announcement and environmental protection, and almost the same. All diesel engine manufacturers are in full swing with the layout of the product, so the technology is not a problem. The key is to see the government's efforts!

In fact, prior to the official introduction of the national five timetable, FAW Xichai has actively started to use the DPF's technology reserves of the five national diesel engines on the basis of its strategic vision, international vision, and smart operational plans. With product research and development, and in the first 4DW platform products to complete the first technology upgrade, the current multi-platform products can be batch production, the vehicle announcement thousands of huge.

As other diesel engine plants continue to mature in DPF technology, it is expected that by the end of June 2017, there will be a large number of various platform products of diesel engine plants that will be introduced to the market one after another. Therefore, the production capacity is not a problem, but also depends on the government's efforts!

Looking into the future, environmental protection and energy conservation are the trend. Only by grasping the timing, adjusting and optimizing the product structure, can we enter the high end of the value chain; at the same time, it fully reflects the scientific and technological responsibility and social responsibility of the company.
