Importance of urea for vehicles-urea concentration sensor for diesel vehicles

With the rapid development of logistics and freight, the continuous flow of various trucks on the highway, the prosperity of online shopping has also led to the rapid rise of the freight industry. Anyone who knows about trucks knows: Under the compulsory implementation of national policies, trucks must use urea solutions to deal with exhaust emissions, so the market for urea solutions for vehicles has great potential.

The automotive urea market has increased dramatically-it has become the trend!
According to the requirements of the Ministry of Environmental Protection's National V Standards Implementation Announcement, starting from January 1, 2018, all light diesel vehicles manufactured, imported, sold, and registered in the country must meet the requirements of the National V Standards.
Starting in October 2017, the six northern provinces (Beijing, Tianjin, Hebei, Shandong, Shanxi, and Henan) launched the National Sixth Model and banned the sale of gasoline and diesel for vehicles below the National Six standard.
According to the relevant regulations of the automobile emission standards formulated by the Ministry of Environmental Protection in 2016: starting from January 1, 2020, new vehicles that do not meet the "National Six" emission standards will not be allowed to be produced, sold, or registered. Diesel vehicles will be on the market before 2020.
1. The most basic function of the urea solution for vehicles is to convert nitrogen oxides in vehicle exhaust into harmless nitrogen and water, which is energy-saving and environmentally friendly, and enables vehicles to meet national exhaust emission standards.
2. Through the intelligent control of the SCR system, the mixer will not start when the urea solution in the storage tank is insufficient. In order to ensure the normal driving of the vehicle, sufficient urea solution should be prepared.
The use of different quality urea solutions also results in different vehicle maintenance. When the selected urea solution is not pure enough, and there are impurities such as particulate matter and heavy metal ions, it will cause serious damage to the nozzles, filters and other parts of the vehicle SCR system, resulting in unnecessary economic losses. If the low-quality urea solution is not high in chemical composition, when heavy metals and other chemical components are present, it will chemically react with the catalyst to reduce the exhaust gas conversion effect, and the mixer truck may even lose its effect. Therefore, when choosing urea solution, we should try to choose high-quality products to control the maintenance cost of the vehicle.
The urea content does not meet the standard requirements. Urea content is an important quality index of urea aqueous solution for vehicles. Too high urea content will cause urea pollution and secondary pollution (high temperature hydrolysis of urea to produce ammonia and carbon dioxide). Too low urea content will reduce the conversion efficiency of nitrogen oxides in the tail gas to nitrogen, resulting in some nitrogen oxides still not It is reduced and discharged directly into the atmosphere. In addition, the urea content will affect the crystallization point of the urea aqueous solution, which may block the urea infusion tube and the nozzle.
Hunan Chuyi Measurement & Control is a private high-tech enterprise in Changsha and a cooperative enterprise supported by the Innovation Fund of the Ministry of Science and Technology. With dozens of inventions, through the application of advanced photoelectric conversion technology, * design philosophy, modular design architecture, the first to develop the first domestic diesel vehicle urea concentration detection sensor . The vehicle-mounted urea concentration detection sensor is directly installed in the urea tank quickly. By introducing the vehicle OBD system, the urea concentration in the urea tank is continuously monitored, and the detection data is transmitted to the trip computer in real time to facilitate the tracing of historical data. At the same time, it can avoid filling unqualified vehicles Use of urea and abnormal NOx emissions due to fluctuations in urea concentration.
Vehicle urea concentration detection sensor detection principle: The light emitted from the LED passes through the optical fiber and enters the sapphire prism from one side of the sapphire prism, and reaches the contact surface between the prism and the liquid material. According to the refractive index of the liquid at the contact surface, a The partial light is totally reflected to the other side of the prism, and the position of the totally reflected light will change due to the change of the critical angle (the critical angle will be different due to the different refractive index of the liquid). The linear array CCD is used to accurately detect the total reflected light. Position, and each position corresponds to the refractive index. The refractive index and concentration of vehicle urea solution at different temperatures also have a corresponding relationship, and the refractive index increases with increasing concentration. Measuring the refractive index of urea solution can also help to further verify the urea solution of vehicle Concentration and quality. Chuyi measurement and control vehicle urea concentration detection sensor detects the concentration without mechanical action measurement, ensuring stability and long life.
