Research of the effect of depressant-dispersant additives on low-temperature properties of diesel fuel
For the automobile fleet of the Russian Federation, the use of both gasoline engines, diesel engines and gasoline engines with GBE is typical. For 2016, the number of cars running on diesel fuel is estimated at 7.7 %. The percentage is small, but for the Russian fleet in kind, the number of cars with a diesel engine is very high. In addition, the importance of diesel cars is increased due to the use of such vehicles in freight traffic, in passenger transportation and in other commercial areas. Thus, taking into account the climatic features of Russia, the low-temperature properties of diesel fuel are very important. In oil refining, various methods are used to improve these properties. The two most common and effective are: the change in the fractional and component composition of the fuel, and the second and more economical is the use of depressant dispersant additives.
