Diesel fuel

Diesel fuel

Diesel fuel is a fuel oil, which is used in internal combustion engines with compression ignition (compressed). The main consumers of diesel fuel - cargo transport and agricultural engineering.

Refining industry produced diesel fuel according to GOST 305-82 of three grades:

The summer diesel fuel is applied at ambient temperatures above 0 ° C. The temperature should not be below 0 ° C, it is generally used in summer. Production of DTL, compared with the other types of diesel fuel is cheaper, so it is summer diesel fuel is the cheapest.

The winter diesel fuel is applied at the temperatures down to -20 ° C (in this case, the winter diesel fuel should have a pour point <-35 ° C and cloud point <-25 ° C) or winter diesel fuel applied at the temperatures up to -30 ° C, so that diesel fuel should have a pour point <-45 ° C and a cloud point <-35 ° C) it is generally used at the temperatures from -20° C to -40 ° C as a pour point of the winter diesel fuel is 45 ° C.

Arctic diesel fuel is applied at the temperatures down to -50 ° C. The sulfur content in winter and summer diesel fuel doesn’t exceed 0.2% - for the fuel of type I and 0.5 - for the fuel of type II and for the arctic diesel fuel - 0.4%.

To satisfy the requirements for diesel fuel it is allowed to use fuel with pour point 0 ° C without rationing cloud point. In accordance with GOST 305-82 adopted the following notation of diesel fuel: the summer diesel fuel is ordered taking into account the sulfur content and flash point (the summer diesel fuel - 0 ,2-40), the winter diesel fuel - the sulfur content and pour point (the winter diesel fuel -0, 2 - minus 35).
