Washing powder is what things? Why should the car to use it?

Washing powder generally refers to the truck and diesel truck use detergent solution, hereinafter referred to as washing powder, also known as diesel exhaust processing liquid, detergent powder, automobile, environmental protection, such as urea. Washing powder is by urea ( Vehicle) And ultrapure water ( The resistivity is greater than 15 megohm) Through washing powder production equipment production. Along with the increase in vehicles, vehicle exhaust pollution is increasingly serious, people pay more and more attention to the management of vehicle exhaust. And some countries in the world in the early 60 s, 70 s and set up relevant laws and regulations. Our country is relatively late start in 1983 issued the first batch of motor vehicle exhaust pollution control standards. The kingdom of recent six emissions standards, respectively by the environmental protection department, general administration of quality supervision, inspection and quarantine on December 23, 2016, issued on June 22, 2018, the light vehicle emissions limits and measurement methods ( China's sixth stage) 'Since July 1, 2020 implementation, the heavy duty diesel emission limits and measurement methods ( China's sixth stage) 'Since July 1, 2019. A motor vehicle in order to achieve discharge standard, thus increasing a series of measures. More common with gasoline vehicle used by the three yuan catalysts and diesel motor vehicle diesel engine used in the SCR exhaust aftertreatment, and we often say that the washing powder processing system is SCR diesel engine exhaust gas treatment scheme, also referred to as 'SCR. Washing powder processing system to work normally, need a consumables that is detergent solution. Some drivers friends in order to reduce the cost, do not use or water instead of washing powder, etc. , will cause the automobile exhaust not up to standard, if the car tail gas to being checked by related departments to make 200 yuan will be punished. Punishment is based on the violation of the law of the People's Republic of China on the prevention and control of atmospheric pollution article 113 ( In violation of the provisions of article one hundred and thirteen of motor vehicle drivers driving emissions test unqualified motor vehicle on road, the traffic administrative department of the public security organ in accordance with the law will be punished. ） Punishment, according to the law of the People's Republic of China on road traffic safety '(article 90 Article ninety of the motor vehicle drivers in violation of road traffic safety laws and regulations about the traffic rules, shall be given disciplinary warning or below 20 yuan and 200 yuan fine. It is otherwise provided for in this law, shall be punished in accordance with regulations. ） 。 Some people may think it few fine only 200 yuan, but the long-term use of inferior detergent washing powder processing system or something else, can cause serious damage to the system, and a set of washing powder processing system at present market price is in ten thousand yuan. So you don't want to save the cost of a little detergent and cause environmental pollution and the damage of the washing powder processing system, and their own interests can cause loss to the environment. By the end of June 2018, the national truck has a total of 24. 7 million cars, compared with the end of last year, an increase of 1. 28 million vehicles, growth of 5. 5%. New registration truck in the first half of 2018, 1. 72 million vehicles, significantly higher than the same period last year, 1. 56 million registrations, to record levels. Thus the truck number is also increased year by year. A freight car urea consumption accounts for roughly 3% of the fuel consumption - Around 5%, about 23 liters of filled with urea, basically range - in 1500 - About 1800 kilometers. If a truck driven an average of more than 150000 kilometers, a year a kilometer consumes about 0. 015 litres of detergent solution, computed by a freight car consumes about 2250 litres a year washing powder, according to the 2018 national truck has 24. 7 million cars, the country consumes about washing powder 555 a year. 7. 5 billion litres.
