-10 What is the freezing point of diesel oil?
Diesel oil is not called freezing point, but "freezing point". -10 The freezing point of diesel oil is -5 degrees Celsius. Freezing point is an important index to evaluate the fluidity of diesel oil. It represents the lowest temperature at which fuel can be transported without heating. The freezing point of diesel oil refers to the highest temperature at which oil is cooled to lose fluidity under specified conditions.

The freezing points of other diesel oils are: 10 diesel oil is 12℃, 5 diesel oil is 8℃, 0 diesel oil is 4℃, -20 diesel oil is-14℃, -35 diesel oil is -29℃ and -50 diesel oil is -44℃.

Extended data

First of all, diesel oil is classified as follows:

1. According to different densities, it can be divided into light diesel oil (boiling point range is about 180-370℃) and heavy diesel oil (boiling point range is about 350-4 10℃).

2. According to the classification of freezing point, light diesel oil has six grades: 5, 0,-10, -20, -35 and -50, and heavy diesel oil has three grades: 10, 20 and 30.

Second, the use of diesel oil is as follows:

High-speed diesel engines (for automobiles) are more fuel-efficient than gasoline engines, and the demand for diesel is growing faster than gasoline. Compared with gasoline engines, diesel engines have the advantages of high thermal efficiency, high power, low fuel consumption and good economy, so they are widely used. Mainly used as power for tractors, large cars, diesel locomotives and civil engineering, excavators, loaders, fishing boats, diesel generators and agricultural machinery.
