Gasoline is the power source of fuel vehicles, without gasoline, even expensive cars can not move. Gasoline is divided into different grades, the higher the general label, the better the quality of gasoline, the stronger the power performance. Many luxury cars are recommended to add No. 95 gasoline, and when the owner goes to refuel the car, he will also add the corresponding number of gasoline to the car according to the suggestions of the car manual.
But now the price of gasoline is rising rapidly, before the 95 gasoline a liter as long as 5.5 yuan, but after last year's "14 consecutive rises", the price of 92 gasoline rose to more than 7 pieces, the price of 95 gasoline has risen to 7.5 yuan, higher than before 2 yuan, a full tank of gasoline is also 40 or 50 yuan higher than the original.
Fuel is the biggest expense in car maintenance, and rising gasoline prices will make the owner's cultivation pressure greater. In order to reduce the pressure of car ownership, some car owners have turned No. 95 gasoline into No. 92 gasoline. However, we have also heard that marriage fake gasoline is not good for cars, and if the car that used to add No. 95 gasoline is suddenly replaced by No. 92 gasoline, what adverse effects will it have on the car?
Cars that add No. 95 gasoline for a long time, and occasionally add No. 92 gasoline, will not have much impact on the car, and they will not feel any obvious difference when driving. But if you change directly from No. 95 gasoline to No. 92 gasoline, after half a year, the owner will feel a significant difference.
The difference between No. 95 gasoline and No. 92 gasoline
The biggest difference between No. 95 gasoline and No. 92 gasoline is that the composition content of n-heptane and isooctane is not the same, No. 92 gasoline contains 92% isooctane and 8% n-heptane, and No. 95 gasoline contains 95% isooctane and 5% n-heptane.
The higher the isooctane number, the better the explosion resistance of the gasoline. Compared with No. 92 gasoline, No. 95 gasoline has a higher isooctane number and better knock resistance. In the high temperature and high pressure environment, the impact on the vibration frequency of the piston is smaller, which is conducive to the engine work.
After the car with No. 95 gasoline is replaced by No. 92 gasoline for a long time, the owner will not feel any difference at first. But after a period of use, the owner may feel that the power of the car is not as strong as before, and the distance of running is also shorter.
In addition, the car company's car manufacturing technology has also advanced, and the accuracy of the sensors and driving computers on the car is much higher than that of the previous car. After changing the gasoline from 95 to 92, the ignition value detected by the sensor will also change, and it will correct the time when the car ignites.
When using No. 95 gasoline, the ignition angle can find an appropriate time, and the combustion rate of gasoline will be much better. The ignition angle of No. 92 gasoline will be slightly earlier, not up to the right time as No. 95 gasoline, so after switching to No. 92 gasoline, the power of the car will be weakened.
summary:
Since gasoline is divided into different grades, it means that their functionality is different, and the higher the label, the stronger the functionality of gasoline. The manufacturer recommends adding No. 95 gasoline to the car because the gasoline of this label can maximize the power performance of the car, so it is the right thing to refuel according to the suggestions given by the car company when refueling.
However, the car is a machine, and "eating coarse grains" can also run, but it will be relatively poor in terms of power output. If you think that No. 95 gasoline is too expensive, you can add No. 92 gasoline. However, before changing gasoline, it is best to clean the oil pipeline first, do not mix with refueling.
