Domestic diesel fuel is classified by pour point, with light diesel having six grades: 5, 0, -10, -20, -35, -50, and heavy diesel having three grades: 10, 20, 30. The relevant introduction to diesel is as follows: Introduction to diesel: Diesel is a light petroleum product, a complex mixture of hydrocarbons (carbon atoms number about 10-22). It is used as fuel for diesel engines. It is mainly blended from diesel fractions produced through processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking. Uses of diesel: The most important use of diesel is for diesel engines in vehicles and ships. Compared to gasoline, diesel has a higher energy density and lower fuel consumption rate, but exhaust emissions contain more harmful components (NO, particulate matter, etc.).
