The same is 92, and the power of ethanol gasoline is indeed worse than that of ordinary gasoline.
If we pay special attention to power, we can improve the label appropriately and solve the problem of poor power of ethanol gasoline by adding ordinary 95.
It's like: you can't climb a mountain with slippers, so you can not only climb a mountain, but also climb better with a pair of hiking shoes.
92 is ethanol, can adding normal 95 improve the power?
What is the power difference between ethanol gasoline and ordinary gasoline with the same label?
The power gap between ethanol gasoline and ordinary gasoline with the same label is not small.
There is a paper in Journal of Internal Combustion Engine, Experimental Study on the Influence of Ethanol Gasoline for Vehicle on the Performance of EFI Gasoline Engine.
The experiment was carried out with an electronically controlled gasoline engine, burning ethanol gasoline and ordinary gasoline with the same label. The results show that the power and torque are reduced by 6% on average.
With the different throttle opening, the drop range is also different, and the power can be reduced by about 10% at most, with a 10% discount.
Maybe you don't know anything about 10%. Take a Honda Accord as an example: the factory torque is 230Nm, and 10% is 23Nm less.
For a car, the force is amplified by the arm and the gear ratio, and 23Nm is equivalent to holding a pencil tip with a length of 10cm in your hand.
At the other end, a husky weighing 36 pounds hangs, and the whole dog hangs there. The force on your wrist at this time is 23Nm.
Ethanol gasoline has low calorific value and poor power.
Ethanol gasoline has poor power because of its low calorific value.
There is a message in the car maintenance technology network: all cars have knock sensors. Once knocking is detected, ECU will adjust the ignition advance angle to an angle that will not knock within a reasonable range and make adaptation.
That is to say, when the gasoline added to the car meets the minimum requirements of the label, for example, 92 cars plus 92 cars and 95 cars plus 95 cars.
If the power is calculated in this way, the influence of deflagration on the power need not be considered, and only the calorific value of ethanol gasoline and ordinary gasoline can be compared.
The influence of calorific value on power is like: the physical strength that a person can get by eating half a steamed bread is definitely not as good as that of a big fish and big meat.
Or this paper in the Journal of Internal Combustion Engine: the calorific value of ethanol gasoline is lower than that of ordinary gasoline, which is equivalent to 93.5% of ordinary gasoline, so the power loss is 6%.
Does "Yi" add up to 100%? It is 99.5%. All kinds of communication will have an impact and will be consumed.
How much power can you increase by adding normal 95?
Because of the poor power of ethanol gasoline, it is impossible to add 92% regular gasoline, so adding 95% regular gasoline can also solve this problem.
The difference between 95 and 92 is actually the difference in octane number.
This is like: the same bowl of noodles, plus an egg, called egg noodles; Add eggs and beef, and it becomes beef and egg noodles.
A 92, a 95. This noodle is the same as soup.
There is a paper "Quality and Economic Evaluation of Automobile Gasoline" in the Journal of Contemporary Chemical Industry.
92 # base oil can be changed into 95 # gasoline by adding 1 1.54% MTBE additive. At this time, the calorific value per unit volume decreased by 1.69%.
If 12% aromatic hydrocarbon reaches the No.95 standard, the calorific value per unit volume will increase by 1%.
That is to say, when 92 # ordinary gasoline is replaced by 95 # ordinary gasoline, the power varies between-1.69% and 1%.
But what additives are used, the refinery comes according to its own plan, and what oil we add is not necessarily.
This kind of oil is put in front of you. You can see and smell it. You can't drink it if you are brave or not, can you?
So: Counting the 6% gap between 92 # ethanol gasoline and 92 # regular gasoline, how much can 95 # regular gasoline improve compared with 92 # ethanol gasoline?
4.3 1% to 7% power, the difference is probably so much.
It's all ethanol and gasoline. Is it necessary to add 95?
If it can be added to the normal 95% area, it will be changed to 95%, which can cope with the depression of ethanol gasoline power decline.
But in some places, even 95% is ethanol gasoline. Is it necessary to add 95 ethanol gasoline? Still compare calorific value.
The specific parameters of the national standard GB18351-2017 "Automotive Ethanol Gasoline (E 10)" are only different in octane number among different brands of ethanol gasoline.
Speaking human words: No matter 95 or 92 ethanol gasoline, 10% of the fuel is ethanol. This is the same, just compare it with gasoline.
This is like: the set meal is a hamburger with French fries and a coke; The second set meal is popcorn, French fries and coke.
Then what are you better than? Right? All you have to do is compare hamburgers with popcorn. French fries and coke are the same.
I caught up with the celebration today, and I bought a set meal and got a cone. Comparing set meal 1 with set meal 2, only hamburgers and popcorn are different.
That is to say, when 92 ethanol gasoline is replaced by 95 ethanol gasoline, the power change is also between-1.69%- 1%.
Adding normal 95 is more powerful than adding 92 ethanol.
In a word, the requirement for automobile oil is 92, and adding ordinary 95 gasoline can improve a lot of power than adding 92 ethanol gasoline.
But if you usually add ethanol gasoline in 1992 and 1995, there is no need to toss, because there is not much difference.
Moreover, it is even possible to encounter the reverse promotion and negative optimization of power, which is not worth the candle. I find this situation boring.
