| Abstract: | To ensure the good lubricity of ICE oil at low temperature,different low temperature performance testing methods including pour point,low temperature starting,low temperature pumpability and scanning Brookfield viscosity were made at home and abroad.The testing principles of different measuring methods were introduced and compared,and then it was pointed out that the corresponding of different measuring methods was the oil flow properties under different working conditions.Finally,the influencing factors of... |
