When you are driving on the road, the car is unstable after refueling, refuelling is weak, and the exhaust pipe emits thick black smoke, which is likely to be a "black heart oil" trick. Due to the low price of counterfeit diesel fuel, private gas stations, rural gas stations, black refueling stations and black refuelling vehicles are often the main sales sites for such diesel. The price of "black heart oil" is exciting, but do you know what kind of harm it will cause to your car?

What harm does "black heart oil" cause?

● Harmfulness of inferior diesel:

1. The diesel with higher sulfur content in inferior diesel has considerable harm to diesel engines.

If the sulphur content is too high, the lubricity of the oil will be reduced. In other words, a high content of sulphur will lead to a drop in the quality of the oil and the engine will not be able to obtain a good lubricating effect. The long-term use of the engine will result in serious wear and tear of the engine. Large corrosion.

Severe engine wear and severe corrosion

2. Inferior diesel fuel with low calorific value that does not meet the standard will not burn well, which will make the fuel consumption rate too high.

The engine's power is not up to the standard, causing the engine's performance to fail to reach the standard, and the performance is not normal enough. This situation can easily lead to problems such as the vehicles that are often mentioned by the people: “Climbing is boring, fuel is weak, and the car is not strong”.

3. The bad quality of diesel with high residual carbon content is more harmful.

Because of the high content of low-quality gasoline itself, these colloidal substances easily block the oil passages and injectors as gasoline passes through the vehicle's fuel supply system. After entering the combustion chamber, the combustion chamber, piston ring groove, spark plug, intake valve back, intake port and other parts of the combustion chamber will generate a lot of carbon deposition after burning in the combustion chamber together with diesel fuel, which will seriously affect the combustion effect of diesel fuel.

Produce a large amount of carbon in the engine

Simultaneously, carbon deposits also cause the temperature in the engine combustion chamber to be too high, and the high temperature environment will cause damage to the piston and piston rings of the engine, further affecting the service life of the engine.

4. The composition of inferior diesel is complex, and it will produce more harmful substances after combustion, which is very harmful to the environment.

In order to reduce production costs, most fake diesel fuels have excessive sulfur content and have a short storage cycle, generally only about 20 days. They will quickly oxidize and black after release, and release harmful gases, which will bring drivers and occupants a long time. Injury to the body; in addition, sulfides and PM particulate matter that are discharged after insufficient combustion further aggravate environmental pollution.

5, black gas station security facilities are not in place, accidentally may become a "time bomb", threatening the lives and property of neighboring residents.

According to national regulations, gas stations must have relevant business qualifications and procedures such as business licenses, “refined oil retail business licenses” and “dangerous chemicals business licenses”. From a safety point of view, the buildings in the regular gas stations have stringent fire protection requirements, and all electrical appliances such as switches, wires, and lights must be explosion-proof. The "black gas station" threshold is extremely low, facilities and equipment are simple, safety clearance is insufficient, operators do not have qualifications for employment, weak safety awareness, fire equipment is not up to standard and so on.

According to the survey, the “black oil station” is not only unlicensed, and even when someone is refueling, they are still “spraying”. After smoking, cigarette butts are thrown everywhere. It is simply a matter of personal safety and the safety of others.

● Summary

"The poor quality oil is not resistant to fire and it also destroys the car. The saved oil money is not enough for repairing the car!" An old driver said that he had joined the bustle to the side of the road when he first entered the market. The last thing he discovered was simply not worth the candle; The oil from the black gas station is unknown, oil is difficult to guarantee, and it is difficult for people to use it safely. The old driver suggested that the card friends, it is best not to covet cheap, or go to the regular gas station.
