The China International Diesel Engine Summit Held Engine National IV Demand

The 2013 China International Diesel Engine Summit was held in Beijing on December 5-6. The conference aims to build a government, industry leaders and relevant professionals to discuss the best platform for energy-saving emission reduction policies, regulations, latest technological achievements, and future technological development trends of diesel engines, so as to produce for the participants and for auto parts. Enterprises, bring real value to the society for the automotive aftermarket.

The summit meeting conveyed the requirements of the Chinese government for environmental protection of diesel engines : Since July 1, 2013, diesel engines have been implementing national IV emission regulations nationwide; laws and regulations governing motor vehicle emissions have been submitted to the National People's Congress. Conduct the review. As the largest manufacturer and supplier of automotive exhaust gas reductant in China, Qin Jian, general manager of Koizumi, gave a speech on the theme of "AdBlue's National Standards and Infrastructure Construction Process."

Compared with gasoline engines, the thermal efficiency of diesel engines is 30% higher, and the greenhouse effect caused by emissions is 45% lower than that of gasoline. However, the harmful particulates emitted by diesel engines after combustion are too large, which requires strict emission regulations for the exhaust of diesel engines. Emissions are regulated and supervised. On July 1, 2013, the National Environmental Protection Agency has officially implemented the “National IV” emission standard. Currently, many provinces and cities such as Beijing, Guangdong, Shanghai, Zhejiang, Jiangsu, and Shenzhen have been fully implemented. Under such circumstances, whether it is commercial Vehicles, non-road mobile machinery, engine manufacturing companies, or emission technology specialists need to increase their practical application of emissions technologies and lay a solid foundation for the full implementation of the “National IV” emissions in 2014.

As far as technology is concerned, industry experts present at the site have also stated that SCR technology is the mainstream technology for implementing IV emissions from diesel engines regardless of which aspect they consider. Because of its good power, it can meet strict emission standards, and has low requirements for cooling systems and is not easy to be blocked. At present, SCR technology routes are commonly used for heavy-duty trucks, passenger cars, and public transport vehicles. However, SCR systems need to add exhaust gas reductant to the exhaust gas exhaust system. The nitrogen oxides in the exhaust gas are converted into nitrogen and water. The reducing agent here is the specific concentration of AdBlue aqueous solution, which means that the automotive AdBlue solution will become a consumable product with the same properties as diesel.

The AdBlue national standard for vehicles, namely the “Nitrogen Oxide Reducing Agent for Diesel Engines Urea Solution”, was implemented on July 1, 2013. This standard was participated in discussions and development by Jiangsu Kelansu Gas Vehicle Environmental Protection Technology Co., Ltd. and is the first in China. A national standard for automotive urea solution products. It is completely consistent with the ISO international standards and the German DIN standard performance indicators. The implementation of this standard provides China's urea production companies with legal basis for production, testing, storage, etc. of urea for vehicles.

According to statistics, heavy-duty diesel vehicles sold 880,600 units in 2011, and sold 366,000 units in 2012. In 2013, they are expected to sell 75-76,000 units annually. The heavy-duty diesel equipped with SCR system is predicted by vehicle-related professionals to grow at a rate of at least 500,000 vehicles a year. By the end of 2015, the national IV diesel vehicle fleet is expected to reach a theoretical capacity of 1.25 million units. By the end of 2017, it can theoretically reach 2.25 million units. Vehicle. If the average annual consumption of 2 tons of diesel exhaust gas treatment fluid (usually diesel fuel exhaust fluid consumption is 4% to 6% of diesel fuel consumption) is estimated for each heavy-duty diesel vehicle, the exhaust gas to 2015 and 2017 The total domestic demand of the treatment liquid will reach 2.5 million tons and 4.5 million tons respectively. Since China's AdBlue market has just started, the sales network needs to be accelerated. General Manager Qin Jian of Jiangsu Kelansu Automobile Environmental Protection Technology Co., Ltd. stated that as the largest domestic manufacturer of AdBlue for vehicles, it will continue to promote the construction of AdBlue channels for vehicles throughout the country, ensuring that all users can be added at any time throughout the country. Vehicle AdBlue contributes a lot to the control of vehicle exhaust emissions.

PE WAX

As a lubricant, it has stable chemical properties and good electrical properties. Used as a lubricant for cable insulation materials, it can enhance the diffusion of fillers, increase the extrusion molding rate, increase mold flow, and facilitate demolding. Main scope of application: Can be widely used in the manufacture of masterbatch, granulation, plastic steel, PVC pipe, hot melt adhesive, rubber, shoe polish, leather brightener, cable insulation, floor wax, plastic profiles, ink, injection molding and other products.
