In order to protect the environment and reduce the emission of nitrogen oxides in the exhaust of diesel vehicles, my country compulsory installation of SCR (oxidation catalytic technology) systems for all diesel vehicles above the National IV standard. Vehicle urea is an essential additive for the SCR system. Reduce 90% of nitrogen oxides and 80% of particulate matter in diesel vehicle exhaust. Vehicle urea filling machine is a liquid volume measurement system for filling vehicle urea solution for diesel vehicles with SCR system.
In February, the Mianyang Metrology and Testing Institute received a call from the relevant person in charge of the Sichuan Mianyang Petroleum Branch of Sinopec Sales Co., Ltd., hoping to test its newly-added measuring instrument, the urea filling machine for vehicles, to ensure safety protection. Work to protect the legitimate rights and interests of consumers and create a social fair and harmonious atmosphere.
At present, domestically, there are no regulations for the measurement and verification of automotive urea filling machines, and the Mianyang Metrology and Testing Institute has never carried out calibration or testing of automotive urea filling machines. Facing the needs of local enterprises on measurement technology, the leaders of the Municipal Metrology Institute attached great importance to it, organized professional and technical personnel, consulted relevant technical materials, and referenced the measurement method of the JJG 443-2015 "Fuel Dispenser" verification procedure, which is basically the same principle. Test plan with urea filling machine". Because the urea solution is corrosive to iron, copper, aluminum and other metals, in order to ensure the accuracy and feasibility of the test plan, professional and technical personnel have carried out 6 systematic and comprehensive test experiments successively, and obtained accurate and reliable experimental data. It was approved by the person in charge of the company. Recently, the Municipal Metrology Institute carried out the test work of the vehicle urea filling machine for the company, successfully completed the task and issued the test report, which won unanimous praise from customers.
As the country attaches great importance to air quality, more and more opportunities for vehicle urea refueling appear at gas stations. This test protects the legitimate rights and interests of consumers, meets the needs of the market, and provides a reference data basis for local governments to formulate relevant regulations. The party members of the Municipal Metrology Institute expressed that they would continue to stick to their original aspirations, act bravely, carry forward the spirit of arduous entrepreneurship, and work hard to ensure that the "14th Five-Year Plan" has a good start and a good start, and will greet the 100th anniversary of the founding of the party with excellent results.
