·Tianjin will promote the first change of oil for ethanol gasoline owners

Tianjin North Net News: Reader Mr. Liu: Yesterday, I saw the report of "Tonight's Evening News". In the future, Tianjin's cars will be replaced with ethanol gasoline. I would like to ask what is ethanol gasoline. Does this kind of gasoline have an impact on the power and parts of the car? In addition, what are the precautions when the car is replaced with oil for the first time?

“There is something in your speech” columnist: Wang Zheng, director of Tianjin Automotive Online Electronic Control Technology Key Laboratory, and Sun Liang, an expert from Tianjin Automobile Distribution Association, said that the promotion of ethanol gasoline in this city is to better reduce automobile exhaust pollutants. Emissions and improvement of the ecological environment. Ethanol gasoline is relatively mature at the technical level, and there is no need for car owners to worry about it.

What is ethanol gasoline?

At present, China's comprehensive promotion is E10 ethanol gasoline. Simply put, this ethanol gasoline is a mixture of 10% fuel ethanol and 90% regular gasoline. Ethanol gasoline is marked with the letter E in front of the gasoline label to distinguish it from ordinary gasoline. For example, the current common gasoline label is 95#, 98#, etc. After changing to ethanol gasoline in the future, the label will become E95#, E98# and so on.

Will the fuel consumption increase after use?

Experts said that the authoritative research institute has done a sample test, and the gap between the addition of 10% ethanol gasoline and ordinary gasoline is not large. For example, if a car is filled with 50L of ethanol gasoline, it may only run 20 to 30 kilometers less than ordinary gasoline.

Will the power be worse after use?

The theoretical air-fuel ratio of ethanol gasoline is lower than that of gasoline. When the fuel injection amount is the same, the effective heat efficiency of the engine is improved. For example, a car with a displacement of 1.3, 1.5, and 1.6 basically does not feel the difference during driving.

Will there be a problem with the car after using it?

Experts suggest that the owner of the car adds ethanol gasoline for the first time. It is best to leave half a box of regular gasoline in the fuel tank, so that the vehicle's computer control system has a self-adaptation adjustment period. After that, the owner half-box and half-tank oil is gradually replaced and refilled to replace the vehicle. The fuel can make a smooth transition. A small number of cars may have engine shake after the first addition of ethanol gasoline. After cleaning the oil circuit after finding the problem, the problem can be solved. Vehicles that are older and infrequently used are advised to be cleaned before oil changes. In addition, some high-end cars may have a fault light alarm after the first addition of ethanol gasoline. At this time, as long as the fault code is cleared, adding a small bottle of fuel improver will be eliminated, and the owner does not have to worry too much.
