Focus on energy-saving emission control for automotive engines

On October 19, 2016, the "2016 Automotive Engine Energy Saving and Emission Control Summit" was opened in Hefei. The summit revolved around the “National Standards Interpretation and Overall Trends of the Automotive Market”, “Traditional Internal Combustion Engine Optimization with New Standards, and SCR, DPF, TWC, LNT, etc. Tail Gas Treatment Solutions”, “Hybrid, Clean Energy Power Systems and Emissions Handling”. , "Car urea, lubricants, antifreeze and other product markets," and other content, together with industry experts to exchange advanced technologies at home and abroad to discuss the future of the industry.

Recently, the Ministry of Environmental Protection issued a solicitation of opinions on the “Limits and Measurement Methods for Vehicle Exhaust Pollutants for Compression Ignition, Gas Fueled Ignition Engines and Vehicles (China's Sixth Phase)”. The article clearly stated that since January 1, 2019, all types of new engines and new automobiles undergoing type inspection should meet the requirements of this standard. From January 1, 2020, any new vehicle that does not meet the "Sixth National" emission standard will not be manufactured, sold, or registered. New engines that do not meet the requirements of this standard may not be produced, sold, or put into use.

This standard not only further increases the requirements for controlling the content of nitrogen oxides (NOx) and particulate matters (PM) in the exhaust gas of motor vehicles, but also puts emphasis on six key control points, including modifying RDE testing requirements and improving OBD testing requirements. Corresponding to the seven test tests. With the implementation of the Sixth National Emission Standard, the National Energy Administration also released the draft of the six national mandatory standards for “gas gasoline” and “vehicle diesel” in July 2016. A series of actions show that the Chinese government is actively promoting the process of controlling motor vehicle exhaust pollution and improving air quality.

In response to the background of the Sixth National Standard released, at this meeting, the Ministry of Environmental Protection’s motor vehicle emission control center, Wang Jun, focused on the analysis of the six emission standard schemes for light vehicles and heavy vehicles. She pointed out that, unlike the previous standards, the standard limits for gasoline vehicles and diesel vehicles are not the same. In the National Sixth Standard, the pollutant limits for gasoline vehicles and diesel vehicles are the same. In addition, the Sixth National Standard has added new requirements for evaporative emission control, pollutant discharge control at low temperatures, and emission control under actual RDE driving conditions.

According to Yue Xin, a senior researcher at the Chinese Research Academy of Environmental Sciences, fuel quality has a huge impact on air quality. To meet more stringent emission standards, it is necessary to further improve fuel quality and implement more stringent fuel quality standards. He also introduced the detergency and main role of vehicle gasoline and automotive diesel.

In addition to the interpretation of macro policies and market trends, the meeting also discussed the internal optimization and emission treatment of internal combustion engines. At the meeting, the issue of emission control of diesel vehicles was also mentioned several times. The pollution of heavy-duty diesel vehicles is a problem that many cities must face. To effectively control heavy-duty diesel vehicles, it is necessary to establish a comprehensive supervision system for motor vehicle compliance standards, strictly implement motor vehicle and oil product standards, and increase supervision. For heavy-duty diesel vehicles, supervision and inspection shall be carried out in production and sales, and severe violations shall be imposed on illegal production and sales of vehicles that do not meet the emission standards. A multi-pronged approach can significantly reduce the emissions of heavy-duty diesel vehicles.

At present, the six countries of reserve countries and six countries in R&D countries are currently the top priorities for the production of fuel oil, engines, aftertreatment systems, and other related maintenance products for motor vehicles. On October 20th, Qin Jian , general manager of Kelan, attended the summit and delivered a speech. He talked about the development strategy of the vehicle urea industry and exchanged with the industry experts the construction and operation of the vehicle urea ecosystem.

Thermoplastic Road Line Marking Machine

Pavement Hot Melt Road Marking Machine

Latest aptitude program controller from Germany and human-friendly contrarily are adopted in the vibrating marking machine which it possible the prominent marking and prime mark painted at the same time and for just once .It is also equipped with step-less speed changing which makes the movement is carried out at will.It greatly promotes the implementing efficiency and makes the marking accurately fit the shape ,height and space between.It meets the requirement of various road condition and measures up to international norms.The road marks made by it can resist transformation ,abrasion and strikes.
Spots recommended
A.Express way:edge line of the express way ,diversion line,decelerating line near the toll booth and turns in the road.
B.Edge line of the city road,double amber line,cross road,sharp turn,entrance and exit of ramp,
decelerating line in front of the gates of schools,enterprises and institutions.
C.National,provincial and county roads:continuous declivity slope section,sharp turn preparation section,decelerating line before prevarication road,edge line and single amber line in all sections.
Features of fixing
Compulsory deceleration,reminding by shakes,glistening in rainy days and anti-slippery
1.Compulsory deceleration:remind the driver to slow down in dangerous section such as turn and slopes;
2.Reminding by shakes:Remind and warn the diver who drivers in fatigue or absent-mindedly;
3.Glistening in rainy days:Mark driving safe with clearer visual.
4.Anti-slippery:Magnify the friction with road and slow down the vehicle.
Major functions
When the driver is driving in fatigue or absent –mind-eely,the car shakes when it passes over the prominent lines giving out harsh noise.As a result,the driver comes back to sense promptly and readjusts the direction of the car thus preventing accidents.The prominent lines have better tree-dimensional reflection of light so that the driver can tell the direction and lane in rainy days.The mark lines guarantee the security of driver and provide compulsory deceleration and anti-slip-pery.
