What is added to No.0 diesel oil to prevent freezing?

Best answer: No.0 diesel oil can be filtered by changing diesel oil frequently in winter to prevent freezing. The freezing point of No.0 diesel oil is 0℃, and generally, No.0 diesel oil is suitable for use when the air temperature is between 8℃ and 8℃. When the temperature of diesel oil is lower than its freezing point, the fuel system in the engine will deposit wax, blocking the oil circuit and affecting the normal operation of the engine. The choice of diesel oil is based on the temperature in use. The last five grades of diesel oil are mainly selected for diesel vehicles, and 0# diesel oil is selected when the temperature is above 4 degrees Celsius.

Diesel oil is a mixture of light petroleum products and complex hydrocarbons (about 10~22 carbon atoms). Fuel for diesel engine. It is mainly prepared from diesel oil fractions produced by crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, petroleum coking and other processes. It can also be prepared by shale oil processing and coal liquefaction. It can be divided into light diesel oil (boiling point range is about 180~370℃) and heavy diesel oil (boiling point range is about 350~410℃). Widely used in large vehicles, railway locomotives and ships.

The most important use of diesel oil is diesel engine for vehicles and ships. Compared with gasoline, diesel has higher energy density and lower fuel consumption rate. Diesel fuel has low energy consumption, so some small cars and even high-performance cars also switch to diesel fuel.

On October 27, 2017, the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization was preliminarily collated for reference. Diesel oil and light distillate were among the three types of carcinogens.
