[Auto Repair Knowledge]Don’t forget to add fuel additives when changing gasoline

ReducecarExhaust gas pollution and improving the quality of the air environment are imminent. The Beijing Municipal Government has previously made a decision to take the lead in implementing the European automotive exhaust emission standards and the corresponding clean gasoline standards. Some large and medium-sized cities such as Shanghai and Guangzhou have responded positively and issued various policies. And take measures to control automobile exhaust pollution. The country will also implement European emission standards around 2008, and implement corresponding gasoline and diesel standards nationwide.Some car owners found that in the process of replacing old gasoline with Euro gasoline, the gasolinetankImpurities are prone to appear in the gasoline pipeline, and the engine fuel injection nozzle will be blocked.

Phenomenon: The demand for high-grade gasoline is increasing

At present, the number of residents in my country who own high-end cars is increasing, and car owners have an increasing demand for high-grade gasoline that matches their vehicles. In addition, the international standards for fuel vehicles have clear requirements for the cleanliness of the engine, the vehicle's intake valve, the deposition of the combustion chamber, and the cleanliness of the nozzle. Because Euro oil reduces the sulfur content, olefin content and impurity content, and these harmful substances have an impact on the life of the automobile's emission control system, causing the formation of deposits in the nozzle, intake valve, combustion chamber and vaporizer Cause the engine to work poorly. Long-term use of Euro? Oil can extend the "catalytic converter" and "catalytic converter" in the emission control system.Oxygen SensorThe longevity of parts such as ”and the exhaust emission control and conversion purification efficiency are maintained at a high level for a long time. After Beijing’s automobile fuel was changed to the European standard, gasoline detergent and gasoline detergent were added to the automobile fuel. Reduce the formation of deposits in nozzles, intake valves, combustion chambers and carburetors, and clean the above-mentioned parts, especially for gasoline with higher olefin content. The effect is more obvious. It is recommended to use 3M fuel additives.

Symptoms: Engines are prone to malfunction during gasoline replacement

In the process of exchanging European gasoline and old gasoline, after a period of time, it will be found that the following faults are common in vehicles: such as engine failure light alarm, engine acceleration weak, engine jitter, etc. After a malfunction, some vehicles can eliminate the malfunction after cleaning the engine injector, and some vehicles only improve but cannot completely eliminate the malfunction. After multiple inspections, it is found that whether it is removing the engine injector for cleaning or cleaning on the car There are always some impurities in the fuel rail of the fuel injector. These impurities gather at the fuel injector with the flow of vehicle fuel and block the fuel injector, causing engine jitter, weak acceleration, engine light alarm, and out-of-adaptation value, etc. Fault. It is recommended to use 3M fuel additives.

This situation is generally due to the fact that a large amount of impurities in the gasoline tank and gasoline pipeline have accumulated in the vehicle before the addition of European gasoline, which makes it difficult to clean up the impurities in the gasoline tank and gasoline pipeline quickly, and some impurities become strips. The flocculent or iron-cut shape is easy to flow with the gasoline. The impurities can be filtered out in front of the steam filter. The impurities in the gasoline pipe behind the steam filter cannot be filtered out by the steam filter, and they will accumulate on the fuel injection nozzle and cause the fuel injection nozzle to be blocked and the engine Bad work. It is recommended to use 3M fuel additives.

Diagnosis: adding gasoline additives can reduce impurities

The impurities in the gasoline pipe can be cleaned with high-pressure air and gasoline multiple times to reduce the impurities. Because there is a partition in the gasoline tank, it is impossible to reach into the gasoline tank to clean the impurities. You can only empty the gasoline in the tank and flush it with clean gasoline. The cleaning effect is achieved. Therefore, such cleaning is not suitable for vehicles with serious impurities. If the gasoline tank and gasoline pipeline are replaced, the time required for the exchange of gasoline and old gasoline will be shortened, but it is very costly. Auto repair expert Wei Junqiang confirmed that the time required for the exchange process between Euro gasoline and old gasoline is about 3 to 5 months. At present, there are many types of fuel additives on the market, and there is a mixture of fish and dragons. It is recommended that car owners and friends diligently add high-quality additives, such as the well-known brand 3M9828 four-in-one fuel additive, Sinbad fuel additive, Jinlihao, etc., to reduce the amount of fuel in the gasoline tank and gasoline pipeline. Impurities are generated, which will reduce the chance of engine fuel injector clogging.
