The company participated in the development of the group standard "THJX+023-2025 Test Bench Method for Determining the Dull Value of Light Fuel" led by China National Petroleum Corporation Northeast Petroleum Sales Company, with the participation of more than ten units including Guangzhou Customs Technical Center, China Inspection Group, and some provincial and municipal quality inspection institutes. This marks the convergence of the company's original new products towards compliance with the standard.

From January 5 to January 9, 2025, a team of experts from a large petrochemical smelting company in India came to our company to visit and exchange relevant technologies on diesel cetane number determination equipment.

On December 15, 2023, a team of Russian experts came to our company to inspect machinery and equipment.

In April 2023, fuel octane ratings，the combustion analysis test bench delivered by theDooway to Tianjin University successfully passed the acceptance test of various indicators.

After on-site inspection of the factory, the Uzbekistan customer used the company's gasoline octane rating tester for oil sample comparison. After verification, the company's products fully meet the ASTM D2699 and ASTM D2700 standards, dispelling the customer's concerns and doubts. The customer signed a contract with our company in a timely manner. Thank you very much for the customer's recognition.

The aviation kerosene lubricity tester is mainly used to evaluate the lubrication performance of aviation kerosene (jet fuel). By simulating the friction conditions of precision components in the aviation engine fuel system, standard steel balls and annular friction pairs are used to move under controlled conditions, and the size of the wear marks generated on the surface of the steel balls is measured to quantify the boundary lubrication performance of the fuel. ‌

A group of Uzbekistan customers came to the company to inspect the gasoline octane rating tester and requested on-site experiments. The customer requested to calibrate the research octane rating of 93.4 and the motor octane rating of 91.6. They observed the entire testing process on site and were very satisfied with the data.
