Red diesel is smuggled oil, that is, diesel smuggled from Hong Kong. Because the Hong Kong car is not collected road tax, the use of fuel tax method. So belonging to the non-automotive use of diesel fuel is used to add red to identify, (such as factories with small generators, etc.) that is to say that red diesel fuel is Hong Kong did not add road tax, that is, the price is relatively low. So the smugglers from Hong Kong to smuggle red oil over for profiteering, this situation is more serious in Guangdong Province.
Diesel is a light petroleum products, complex hydrocarbons (carbon atoms about 10 to 22) mixture. For diesel fuel. Mainly by the distillation of crude oil, catalytic cracking, thermal cracking, hydrocracking, petroleum coking and other processes to produce diesel fuel distillate blending;
Can also be processed from shale oil and coal liquefaction. It is divided into two categories: light diesel oil (boiling point range of about 180~370℃) and heavy diesel oil (boiling point range of about 350~410℃). It is widely used in large vehicles, railroad locomotives and ships.
The most important use of diesel fuel is for vehicles, ships, diesel engines. Compared with gasoline, diesel fuel has high energy density and low fuel consumption rate. Diesel has low energy consumption, so some small cars and even high-performance cars have switched to diesel.
On October 27, 2017, the World Health Organization's International Agency for Research on Cancer published a preliminary collation of the list of carcinogens for reference, diesel fuel, light distillate in the list of 3 categories of carcinogens.

Uses of diesel fuel:
High-speed diesel engines (for automobiles) are more fuel-efficient than gasoline engines, and demand for diesel fuel is growing faster than for gasoline. Diesel engines than gasoline engines with high thermal efficiency, power, fuel consumption is low, relatively economic, so the application is becoming more widespread.
As a result of high-speed diesel fuel consumption (50 ~ 75g / MJ) is lower than gasoline (75 ~ 100g / MJ), the use of diesel engines, large-scale means of transport is increasing. Diesel fuel is widely used in large vehicles, railroad locomotives, ships.
Mainly used as a liquid fuel for diesel engines, diesel fuel has low energy consumption, low pollution and environmental protection characteristics, so some small cars and even high-performance cars have switched to diesel fuel.
It is mainly used as the power of tractors, large cars, internal combustion locomotives and civil engineering, excavators, loaders, fishing boats, diesel generator sets and agricultural machinery, and it is the diesel engine fuel for diesel cars, tractors and other diesel engines.
