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.
