95% automotive lubricants can be assured
Editor's note: in the middle of winter, automobile engine by what kind of lubricating oil is related to the owner of the safe driving, province bureau of quality and technical supervision of sampling results show that 95% of the lubricating oil can be assured.
Midwinter season, automobile engine using what kind of lubricating oil is related to the owner of the safe driving, province bureau of quality and technical supervision of sampling results show that 95% of the lubricating oil can be assured. Provincial Bureau of quality and technical supervision organization of the inspection unit, on the car with lubricating oil, corrugated boxes and bags of cement 3 kinds of products carried out at the provincial level supervision and inspection. In the inspection of the 36 vehicles with lubricating oil production of 40 batches of products, the product quality of 38 batches of qualified products, the sample pass rate of 95%. Provincial Quality Supervision Bureau relevant person in charge, not qualified to pass the main non qualified oil products for low temperature dynamic viscosity and low temperature pumping viscosity.
Low-temperature dynamic viscosity is lubricating oil in low temperature and high shear rate conditions measured in the size of the friction force measurement, reflecting the lubricating oil in the low temperature flow properties of the engine piston ring and cylinder sleeve part using the unqualified products may cause vehicle can not start in the winter and engine damage.
Cryogenic pumping viscosity is lubricating oil under low temperature conditions through the oil pump is sent to the engine of the friction surface of the ability, it is winter in one of the important quality index of lubricating oil and multi grade oil and lubricating oil according to the classification of viscosity is an important basis, using the project unqualified products easy to make the vehicle suffered serious damage.
