In order to ensure the normal operation of the engine, the cooling system is essential. As an important part of the engine cooling system, cooling fans typically consume 5% to 8% of the engine's energy consumption. From the fixed fan, the thermocouple-type silicon oil clutch drive fan, to the electronically controlled silicon oil clutch drive fan, the upgrading of the fan technology has contributed to the improvement of engine efficiency and energy conservation and emission reduction.
As inventor of silicone oil fan clutch, BorgWarner has been committed to the development and promotion of fan energy-saving technologies. Not long ago, BorgWarner's joint venture in China, Warner St. Long (Ningbo) Co., Ltd. and Weichai Power cooperated on the application of electronic silicon fan clutches on construction vehicles and demonstrated on the Sany mixer truck.
Technical advantages
The electronic silicone fan clutch promoted by BorgWarner in China is a replacement product of the thermocouple-type silicone oil fan clutch. Its principle is to directly read the ECU signal of the engine control module. The internal solenoid valve of the clutch is based on the temperature sensors of various parts of the engine. The information provided controls the speed of the cooling fan so that a more accurate and rapid response can be achieved. In general, the electronic silicone fan clutch has excellent performance in reducing system noise and saving energy.
Test data from the BorgWarner Thermal Systems Europe Technology Center show that cooling systems that use electronically controlled silicone oil fan clutch technology can reduce engine oil consumption by 4% to 8% compared to cooling systems that use traditional bimetallic thermal silicone oil clutch technology. The average temperature is 28°C, tested under load conditions, and this data will be more apparent in winter or no-load conditions.
Currently, electronic silicon oil clutches are mainly used in high-end large passenger cars, trucks, and some construction machinery vehicles that emit Euro III emissions. Almost 70% of commercial vehicles in Europe and North America use this technology. At the commercial motor show in Hanover, Germany, which was held in September this year, almost all heavy trucks exhibited used electronic silicon fan clutches.
Localization development
With extensive experience in Europe and the United States, BorgWarner is also planning to promote this advanced fan cooling technology to the Chinese market. Mr. Cao Guoping, Director of Marketing and Sales of Warner St. Long (Ningbo) Co., Ltd., said that BorgWarner's electronic silicone fan clutch has nearly 2 million mature applications in Europe and the Americas, and we also hope to have a performance in the Chinese market.
However, the Chinese market is different from the European and American markets. On the one hand, emission regulations are relatively low. On the other hand, users are more sensitive to vehicle prices. From the current point of view, the use of electronically controlled silicone oil fan clutches in China is still in its infancy, and it requires a process to be fully promoted. It took almost a decade in Europe to reach the current 70% coverage of electronically controlled silicone oil fan clutches. For the Chinese market, BorgWarner expects the promotion of the popularization process will take 5 to 10 years.
In fact, Warner St. Long's electronically controlled silicone oil fan clutch has been used on some domestic military vehicles and exported to South Korea's Daewoo. As of November 2008, Warner Shenglong has completed nearly 3,000 batches of electronically controlled silicone oil clutches. The cooperation with Weichai Power is to explore further possibilities for application on construction vehicles. In September of this year, the Sany Mixer equipped with an electronically controlled silicone oil fan clutch made fuel consumption tests in Changsha. The test results are very close to those in Europe. They are 5.9% for no-load fuel economy and 4.3% for fuel economy.
Taking into account the special road conditions and driving habits of the Chinese market, Warner St. Long has made many design improvements to electronically controlled silicone oil fan clutches. These improvements have been reflected in this cooperation with Weichai Power. For example, China's roads are relatively bumpy. Due to the special requirements for vibration and balance, Warner Shenglong has made the relevant bearings bigger and added dynamic bearings. In addition, due to the relatively long working hours of commercial vehicles and construction vehicles in China, and the need for an engine cooling system to solve the cooling problems caused by long working hours, Warner Shenglong has cooperated with silicone oil suppliers to improve the formulation of silicone oils. Added antioxidants. In addition, Warner Shenglong has also added a self-protection anti-failure system to the electronically controlled silicone oil fan clutch used in the Chinese market. Once the entire system circuit fails, the system will automatically cut off the connection between the cooling fan and the sensor. Run at a fixed speed.
Localized development and application demonstrations have laid a foundation for the promotion of BorgWarner Electronically Controlled Silicone Oil Fan Clutches in the Chinese market. As China's emission regulations become increasingly stringent, electronically controlled silicone oil fan clutches will gradually be recognized by the market, and Warner Shenglong is ready.
