Wang Binggang, head of the national new energy vehicle technology innovation engineering expert group, Zhang Jinhua, secretary general of the China Automotive Engineering Society, Rao Fangquan, academician of the Chinese Academy of Engineering, and Yan Chuliang, academician of the Chinese Academy of Sciences, first studied the experimental project of Zhongtong New Energy Bus. The room then identified the three scientific and technological achievements in the form of a meeting defense. Sun Qingmin, general manager of Zhongtong Bus, and Wang Qinpu, technical director, attended the meeting. In the end, all three achievements were successfully passed the expert group appraisal and submitted to the Ministry of Industry and Information Technology and the project special office for filing. It is understood that the three scientific and technological achievements passed this time are: key technologies and industrial application projects of the new energy bus advanced power platform, key technologies and industrial application projects of the new energy bus vehicle electronic control system, 100,000 new Energy bus remote monitoring and security management project. The three achievements are also an important support for the two national-level scientific research projects “strategic emerging industry projects†and “innovative engineering projects†undertaken by Zhongtong Bus during the “Twelfth Five-Year Plan†period. “Key Technologies and Industrial Application Projects of New Energy Bus Advanced Power Platform†is one of the core technical achievements of Zhongtong New Energy Bus, including mechanical automatic transmission AMT and its control system, and lithium-ion battery system for new energy passenger vehicles. Optimized design and system integration of key systems such as high-efficiency permanent magnet synchronous motor and its control system, which can break through the integration and control technology of advanced power and vehicle energy system, and solve the reliability and durability of products in large-scale promotion and application. Technical problems with poor safety. It can be said that the system represents the highest level of the complete vehicle control system for plug-in hybrid buses and pure electric buses in China. In October of this year, Zhongtong “New Energy Bus and its electromechanical coupling drive system†also won the gold medal of the first “Province Cup†industrial design competition. With the expansion of the scale of new energy buses, the electronic control system plays an increasingly important role in the safety, energy efficiency and reliability of new energy buses, and has become the "central nerve" of new energy buses. Zhongtong “Key Technology and Industrial Application Project of New Energy Bus Vehicle Electronic Control System†is one of the outstanding representatives. The multi-energy management system developed by the project can rely on various sensors, CAN bus, drive modules, etc. to accurately "feel" the driver's intention, control the operation of the vehicle, and make reasonable calculations for key components of the battery, motor, engine and other systems. Energy distribution, driving safety protection, fault handling, etc. At present, Zhongtong Bus's new energy vehicle electronic control system has been successfully applied to its plug-in hybrid, pure electric and dual-source fast-fill passenger buses. The number of operations exceeds 20,000, the total mileage exceeds 2.6 billion kilometers, and the first fault mileage exceeds 8000 km, and there was no vehicle outage and safety accident caused by power system and high voltage system failure. Zhongtong's “100,000 New Energy Bus Remote Monitoring and Safety Management Project†has been implemented since 2013, and has now formed a remote monitoring and safety management system for 100,000 new energy buses. It takes the new energy vehicle and key component fault warning and safety monitoring as the basic design concept, and comprehensively monitors the whole operation process of the new energy bus. At present, the system has been recorded into 26 categories of DBC database, and more than 60 batches of various models have been entered. More than 600 fault types have been defined, which realizes all-round monitoring and fault warning of key energy information of new energy such as battery, motor and electronic control. The project also has the dual functions of remote monitoring and safety management of new energy vehicles. From January to November 2016, Zhongtong Bus sold a total of 11,241 new energy buses, a record high. At present, the footprint of Zhongtong New Energy Bus has spread all over the country and the provinces accounted for nearly 20% of the industry, which has become the main force for the promotion of new energy buses in China. The source of all these achievements is the mastery of this core core technology. The successful identification of the three scientific and technological achievements marks the smooth completion of the two national-level scientific research projects “strategic emerging industry projects†and “innovative engineering projects†undertaken by Zhongtong Bus during the “Twelfth Five-Year Plan†period, which has not only been further improved. The technical reserve and scientific research strength of Zhongtong Bus in the field of new energy buses also laid a good foundation for Zhongtong Bus to apply for the “13th Five-Year†scientific research project to the four ministries.
Automatic transmission fluid (ATF) is a type of hydraulic fluid used in vehicles with automatic transmissions. It is typically coloured red or green to distinguish it from motor oil and other fluids in the vehicle.
Atf Oil is generally replaced every 120,000 kilometers, and the severe driving conditions are replaced every 60,000 kilometers.
Atf Transmission Fluid must meet the following requirements when working in an automatic transmission:
Automatic Transmission Fluid is developed specifically to meet the requirements of high -performance automatic transmissions. It is suitable for all automatic transmission that requires using the dexrin II specifications.

The “National New Energy Automobile Industry Technology Innovation Project and National Strategic Emerging Industry Project Achievement Appraisal Meeting†organized and hosted by China Automotive Engineering Society was successfully held in Shandong Liaocheng Zhongtong Bus. This meeting is mainly for Zhongtong in New Energy. Three national scientific and technological achievements in the passenger car field were identified.
a) The efficiency of transfer power is related to the viscosity and degree of foaming. Therefore, the viscosity and degree of foaming are required.
b) When ATF works in an automatic transmission, the internal operating temperature of the system can reach -40-170 ° C, the oil flow rate can reach 20m/s, and it is continuously contacting with non-ferrous metals and air, so the oil antioxidant performance is high.
c) When ATF works in the system, the friction and other friction of the bearing and gears in the system must also be lubricated with ATF, so the ATF should have a certain lubrication performance.
d) With the advancement of modern automatic transmission technology, its overall size continues to shrink, but at the same time, it must ensure that its speed and transmission power remain unchanged. Therefore, the larger the ATF proportion.
This product can also be widely used in occasions that require hydraulic transmission, including power steering mechanisms, hydraulic systems, etc., and are not suitable for the DEXRIN VI specifications.
