The exhaust pollution of large trucks is an important factor that seriously affects the parameters of the PM2.5 indicator. According to the data of the Ministry of Environmental Protection, China’s diesel vehicles accounted for only 6.3% of the total vehicle population in 2011, while nitrogen oxide emissions accounted for 67.2% of the country’s total vehicle nitrogen oxide emissions, and particulate PM emissions were also It accounted for 78.8% of the total car's displacement. Managing heavy-duty diesel vehicle exhaust pollution has become a top priority for vehicle emission reductions. A few days ago, Sinopec announced that their new product diesel exhaust gas treatment liquid , can make at least 80% of the nitrogen oxides in the exhaust gas into harmless nitrogen, to meet the national IV, even the national V emission standards. According to the announcement of the Ministry of Environmental Protection, all diesel vehicles must comply with the requirements of the National IV standard from July 1 this year. Compared with the National III engine, the National IV standard diesel engine can not only reduce the fuel consumption by 5-7%, but also reduce the discharge of 80% particulate matter (that is, PM), because the diesel fuel burns more fully. However, under high temperature and high pressure, the nitrogen oxides in the exhaust gas will increase significantly. Qin Yingbin, senior consultant of Tianjin Yuetai Petrochemical Technology Co., Ltd., said that nitrogen oxides and PM are like seesaw. Qiao Yingbin: One pressure goes on, and the other rises. How to do it? Use SCR technology. The diesel engine burns high-temperature tail gas and sprays diesel exhaust gas. Qiao Yingbin's "SCR technology" simply means that the nitrogen oxides in the exhaust gas are converted into nitrogen and water without pollution by the treatment liquid. This method can absorb 80% of the nitrogen oxides in the exhaust. At present, domestic heavy-duty diesel vehicle manufacturers mainly choose this technology to meet the national IV emission standards. However, for every new SCR system in the new car, the cost will increase by 1-2 million yuan. New car configuration SCR system, resulting in increased costs, is it cost-effective? Feng Mingxing, an expert on energy and environment, said that taking into account that the National IV standard diesel vehicles can save fuel, they can offset the cost in use. Feng star: Measured a bit, run 20-30 million kilometers, put this 1-2 million earned back, and the rest are fuel-efficient. The price of the processing liquid is probably equal to the price of diesel. Generally, for each 100 liters of diesel used, approximately 4 liters of diesel exhaust gas treatment fluid is required. In addition to refueling, an exhaust gas treatment fluid is added. Is a truck driver willing to install an exhaust gas treatment system to add fuel and add exhaust gas treatment fluid? The reporter interviewed two truck drivers at random and the drivers said that they were more willing to raise the truck to the National IV standard and install the exhaust gas treatment system. Driver 1: Put on the exhaust system is good, the first is not polluting, the second can save some oil. Driver 2: The exhaust is not up to standard, and even Beijing will not allow it. What do we do with policies? How do we do it? We must implement national IV standards to reduce emissions. Are there any safeguard measures? On the one hand, there are coercive measures. Qin Yingbin, senior consultant of Tianjin Yuetai Petrochemical Technology Co., Ltd., said that a sensor system called OBD will be installed on diesel vehicles. Once the exhaust gas exceeds the limit, diesel vehicles will not be able to open. Qiao Yingbin: You have to add (diesel exhaust fluid), the nitrogen oxides in the exhaust gas are high, and after the OBD passes, the engine's power is reduced. If it is a heavy vehicle, the speed of 15 kilometers goes slowly to refuel. Station, to supplement the diesel vehicle exhaust fluid, after having returned to normal power. On the other hand, Sinopec is also working to reduce the price of tail gas treatment liquids. Zhang Xinchang, deputy manager of Tianjin Yuetai Petrochemical Technology Co., Ltd., said that with the National IV standard diesel vehicles, after July 1 this year, the amount put into the market is increasing, Sinopec plans to build diesel vehicle tail gas treatment fluid Station, from barrel to fill, so that the price of tail gas treatment solution will gradually decline. Zhang Xinchang: At a gas station, using a filling machine to sell diesel exhaust fluids, this is the lowest cost method, and reducing packaging is a trend.
