diesel

Diesel is divided into light diesel oil (boiling point range of about 180-180 ℃) and heavy diesel oil (boiling point range of about 350-350 ℃) two kinds big

Diesel oil solidifying point tiered, there are 10,5,0 light diesel oil, to 10, 20, 30, and 50 seven grades, heavy diesel oil has 10, 30 three grades.

Light diesel oil is diesel cars, tractors and other diesel engine fuel.As with motor gasoline, diesel has a different brand.Division of diesel is based on the freezing point, the current domestic application of light diesel oil according to the freezing point is divided into six grades: 10 # diesel oil, 0 # diesel oil, - 10 # diesel oil, - 20 # diesel oil, and - 35 # diesel and - 50 # diesel fuel.When choosing the basis of diesel is the use of temperature.Diesel cars made after five brand of diesel, the temperature at 4 ℃ above choose 0 # diesel oil;At 4 ℃ -- - 5 ℃ temperature when choose - 10 # diesel oil;Temperature at 14 ℃ - 5 ℃ -- - choose - 20 # diesel;Temperature in - 14 ℃ -- - 29 ℃ when choose - 35 # diesel;Choose brand if it is below the temperature of the diesel, the engine's fuel system may wax, oil plug, affect the normal work of the engine.

Product use

Diesel is widely used in large vehicles, ships, generators, etc.Mainly used for the liquid fuel of diesel engine, due to the high speed diesel engine (car) than gasoline engine fuel, diesel demand is growing faster than petrol.Environmental characteristics of diesel fuel with low energy consumption, low pollution, so some small cars even high-performance cars use diesel.
