Four Electronic Control Common Rail National Standards to be Implemented in March of Next Year

Starting from March 2011, China will implement four national standards for electronically controlled common rail systems. The four standards were separately approved by the National Standardization Management Committee, passed the expert review, and were approved for release in November 2010. These four national standards belong to the “Diesel Electronic Control Common Rail Fuel Injection System” national standard under the jurisdiction of the National Fuel Injection System Standardization Technical Committee (SAC/TC396). They are proposed and drafted by the Wuxi Oil Pump Yuzu Research Institute.

As we all know, the heart of the car is the engine. The fuel injection system, which is the "heart" and central regulating system of the engine and other power equipment, is highly precise and technically intensive. Since the fuel injection system directly affects the exhaust emissions and fuel consumption of the engine, affects the environmental protection, and reduces energy consumption, the improvement of the product performance of the fuel injection system plays an important role in the development of the engine and the automobile and the improvement of their technological level. . For modern vehicle diesel engines, the fuel injection system is also the core of various advanced combustion control technologies. The research and development of various new combustion technologies, vehicles and engines to reduce emissions, reduce fuel consumption, improve power performance and safety and reliability, reduce vibration and noise, improve comfort performance, etc., to a large extent depends on the fuel system Improvements and improvements. With the increasingly strict implementation of emission regulations, energy conservation regulations and noise regulations, higher and higher requirements are placed on engines and fuel injection systems, which makes the improvement of the technical level of the fuel injection system industry even more important. For diesel vehicles, the key to the success of future competition lies in electronically controlled high pressure fuel injection systems. Who controls the fuel injection system, who can dominate the engine and even the entire automotive market. In particular, with the rapid development of electronic technologies, new materials, and new technologies, the fuel injection system has undergone fundamental changes, becoming a new high-tech field and a rapidly growing emerging industry.

The electronically controlled common-rail diesel injection technology represents the highest level and development direction of the current diesel fuel injection system. It is the key technology for the realization of energy-saving and emission-reduction targets for automobiles and the emission regulations for China IV and beyond. At present, the electronic control common rail systems of Germany's Bosch and Siemens, Japan Denso, and Delphi of the United States have been applied in large quantities in developed countries, and have begun to be applied in bulk to the high-end diesel vehicle market in China. The electronically controlled common rail system independently developed by the Wuxi Oil Pump Nozzle Research Institute has also been matched with various types of diesel engines, and has been applied in a small number of applications in urban public transportation and other fields.

However, the relevant standards for electronically controlled common-rail systems are seriously missing. There are no corresponding national standards or industry standards, and there are no corresponding international standards. This not only has no technical regulations that can be based on the R&D, production, sales, and market applications of electronically controlled common rail systems, but it is also difficult for the fuel injection system industry to develop in an orderly manner. Under this background, the Wuxi Fuel Pump Yuzu Research Institute began research and formulation of products and technical standards for electronically controlled common rail fuel injection systems for diesel engines from 2006, and proposed four national standards for electronically controlled common rail systems. On November 10, 2010, the General Administration of Quality Supervision, Inspection and Quarantine, and the State Standardization Administration of the People's Republic of China approved the release of the four national standards in the form of the “Notification on the Approval of the National Standards of the People's Republic of China” (No. 8 of 2010), starting from March 2011. Implementation.

The approval and issuance of the four national standards for electronically controlled common-rail systems indicates that China has mastered the standard discourse rights in today’s automotive core technology fields and is no longer subject to restrictions by multinational corporations. The international standards laid the foundation.
