Recently, Chongqing Changan Automobile Co., Ltd. filed a recall plan with the AQSIQ in accordance with the "Regulations on the Management of Defective Automobile Product Recalls" and the "Implementation Measures for the Management of Defective Automobile Product Recalls", since March 2, 2018, A total of 252,087 vehicles were produced during the recall from July 26, 2016 (inclusive) to February 24, 2018 (inclusive).
The engine electronic control unit (ECU) software of some vehicles in the above range lacks the control of the engine fuel injection strategy adjustment under extreme conditions. When the vehicle is driving in a low temperature environment for a long time and a short distance, the engine oil continues to be in a low temperature state, resulting in The trace liquid gasoline remaining in the oil cannot be vaporized in time and enters the cylinder through the crankcase forced ventilation system to re-burn. After a period of time, there will be an increase in the oil in the oil pan. When the oil is increased to a certain extent, the oil alarm light will be on. If the user ignores the alarm prompt, the continuous running of the vehicle may affect the engine friction pair and the motion pair. In extreme cases, the engine will be damaged and there is a safety hazard. Chongqing Changan Automobile Co., Ltd. will inspect the vehicles within the scope of the recall and upgrade the ECU software and engine cooling system to eliminate potential safety hazards.
Emergency measures: Before the vehicle is recalled, if the oil alarm light is on, the user should contact the nearest Changan Automobile Service Station for assistance.
Chongqing Changan Automobile Co., Ltd. will notify the relevant owners through registered mail, telephone, SMS, etc. through Changan Automobile Special Service Station to arrange free maintenance. The owner can call the service hotline (mobile or landline) or visit Changan Automobile's official website () for more information. Owners can also visit the AQSIQ Defective Product Management Center website () and the WeChat public account (AQSIQDPAC) for more information. In addition, you can also call the AQSIQ Defective Product Management Center hotline to reflect problems during the implementation of the recall or to submit defects.
Ceramic Hybrid Bearings have Steel races and Ceramic Balls. Ceramic Balls are suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Ceramic is non-porous, non-magnetic, non corrosive and lighter than steel. In ball form, ceramic balls are also harder than steel and because ceramic balls are non-porous they are virtually frictionless and capable of spinning faster than steel balls.
Ceramic Balls are usually made of following materials:
Silicon Nitride (SiN4)
Alumina Oxide (Al2O3)
Zirconia Oxide (ZrO2)
Silicon Carbide (SiC)
Because ceramic is a glass like surface it has an extremely low coefficient of friction and is ideal for applications seeking to reduce friction. Ceramic balls require less lubrication and have a greater hardness than steel balls which will contribute to increased bearing life. Thermal properties are better than steel balls resulting in less heat generation at high speeds.
