The difference between 95 and 92 gasoline, ask for advice

The octane number is different, and the riot resistance is different. That's all.

In fact, the biggest difference between 92 and 95 gasoline is the difference in the ratio of n-heptane and isooctane. No. 92 gasoline contains 92% isooctane, 8% n-heptane; By the same token, 95 gasoline contains 95% isooctane and 5% n-heptane. Riot resistance is different.

92 (or 93) is more prone to detonation, and in order to avoid detonation, the ignition time of the spark plug has to be delayed, and the result of the ignition time being delayed is that the power will become relatively poor.

The 95 (or 97) is not so prone to detonation, and the computer can control the ignition moment relatively early, so the power will be relatively strong, and the simplicity is like a sprint race, and the speed of the start will affect the final race result.

The gasoline label represents the anti-knock resistance, and the larger the mark, the better the anti-riot ability, which has nothing to do with the quality of the gasoline itself, nor does it mean that the higher the mark, the less impurities there will be.

Note: There are often friends encountered, occasionally there is no oil in special circumstances, the two oils are mixed and added, and there will generally be no major problems, but they cannot be used for a long time, which will cause detonation, lack of power, etc. The same car with a number 95 will not have a big problem occasionally using a number 92 gasoline, but if it is long-term, it will make the frequency of detonation more frequent and the wear and tear on the engine will be aggravated.

What kind of oil is added to the car is the compression ratio. Generally speaking, the engine with a compression ratio between should be 90 93 gasoline; The compression ratio should be between 90 93 gasoline; The compression ratio between should be 93 95 gasoline; The compression ratio should be between 95 and 97 gasoline, and these relevant data will be clearly indicated in the manual of each car.

Hello, the difference between 92 gasoline and 95 gasoline is that the octane number is not the same, 95 is higher, 95 burns better than 92 and has good power to produce less charcoal. Hope it can help you, just for reference.

For cars, refueling is essential. Now we can often see 92 gasoline and 95 gasoline on the market, and everyone knows that compared to 92 gasoline, 95 gasoline will be slightly higher. As the saying goes, you get what you pay for.

The difference between 92 and 95 gasoline is only the octane number. The octane number is a value that represents the anti-knock combustion capacity of gasoline, and the higher the octane number, the better the anti-knock performance. The standard fuel consists of isooctane, which has very good knock resistance, and n-heptane, which has very poor knock resistance, and its octane number is 100.

Gasoline designation is the ratio of the knock resistance of actual gasoline to that of standard gasoline. The No. 92 gasoline label means that the gasoline of the grade has the same anti-knock performance as the standard gasoline of 92% isooctane and 8% n-heptane, and its octane number is 92; The No. 95 gasoline label means that the gasoline has the same anti-knock performance as the standard gasoline of isooctane 95% and n-heptane 5%, and its octane number is 95; The No. 98 gasoline label refers to the gasoline that has the same anti-knock performance as the standard gasoline of 98% isooctane and 2% n-heptane, and its octane number is 98.

It is very important to choose the appropriate gasoline grade according to the compression ratio of the engine, if the engine with a high compression ratio chooses a low grade of gasoline, the gasoline engine is prone to detonation, and the engine detonation for a long time is easy to cause piston sintering, piston ring short crack and other faults, accelerating the damage of engine parts; If the engine with a low compression ratio uses high-grade gasoline, although the engine knocking can be avoided, the engine with high-grade gasoline and low compression ratio will change the ignition time, resulting in an increase in carbon deposits in the cylinder, and long-term use will reduce the service life of the engine.

The label of gasoline represents the octane number of the oil, and the higher the label, the higher the octane number, the better the anti-knock performance of gasoline. No. 98 gasoline is obviously more resistant to knockout, making the engine run more smoothly, reducing wear and tear, and better protecting the engine.

The methane number in gasoline is different, the anti-knock resistance is different, ** is different, No. 95 will be a little more expensive than No. 92, and the boiling point and temperature when ignited are different.

The ignition point is different, ** is different, the cleanliness is the same, the calorific value is the same, and the power is the same.

The difference between 92 gasoline and 95 gasoline is only the octane number. Gasoline marking does not represent the cleanliness of gasoline and has nothing to do with the quality of the oil. The level of gasoline marking only indicates the size of the octane number of gasoline, and different grades of gasoline should be selected according to the different compression ratio of the engine.

If the engine with high compression ratio uses low-grade gasoline, the cylinder temperature will rise sharply, the gasoline will not be burned completely, and the machine will vibrate strongly, so that the output power will be reduced and the parts will be damaged.

Gasoline designation is the ratio of the knock resistance of actual gasoline to that of standard gasoline. The No. 92 gasoline label means that the gasoline of the grade has the same anti-knock performance as the standard gasoline of 92% isooctane and 8% n-heptane, and its octane number is 92; The No. 95 gasoline label means that the gasoline has the same anti-knock performance as the standard gasoline of isooctane 95% and n-heptane 5%, and its octane number is 95; The No. 98 gasoline label refers to the gasoline that has the same anti-knock performance as the standard gasoline of 98% isooctane and 2% n-heptane, and its octane number is 98.

Gasoline is a specialized fuel used in ignition engines. The appearance of gasoline is generally a water-white transparent liquid with a special gasoline aroma, and the gasoline sold at gas stations is generally motor gasoline and automotive ethanol gasoline. The performance requirements of automobiles for automotive gasoline are:

1. Good anti-explosion;

2. Appropriate evaporation;

3. Good antioxidant stability;

4. Good corrosion resistance and certain environmental protection requirements.

No. 92 gasoline is rich in 92% isooctane, 8% n-heptane; Whereas 95 gasoline is rich in 95% isooctane and 5% n-heptane.

1.The biggest difference between these two types of gasoline is that the content of n-heptane and isooctane is different, among them, No. 92 gasoline is rich in 92% iso-octane and 8% n-heptane; Whereas 95 gasoline is rich in 95% isooctane and 5% n-heptane. The gasoline mark also represents the anti-knock performance of the fuel, and the larger the mark, the better the anti-knock performance.

It is worth mentioning that the gasoline label has nothing to do with the quality of the gasoline itself, and it does not mean that the higher the gasoline, the better, or that the higher the gasoline does not mean that there are fewer impurities or the purer the purity.

2.The so-called anti-knock property refers to the ability of gasoline to resist knocking when burning in the engine, which is the primary indicator of gasoline combustion function, and knocking is caused by abnormal combustion of gasoline in the engine. The octane number is exactly the target of gasoline detonation resistance, the higher the octane number, the stronger the detonation resistance, the higher the compression ratio, the higher the pressure in the combustion chamber, if you use gasoline with low detonation resistance, it is easier to produce detonation, and 95 gasoline has a higher octane content than 92 gasoline, therefore, the fuel has better anti-detonation.

3.To choose the kind of gasoline, it should be determined according to the compression ratio of the engine, and must not blindly use high-grade fuel, because if the compression ratio is not enough, its high anti-knock advantage can not be brought into play, and it will also cause a waste of money. At the same time, choose gasoline that does not match the compression ratio, and the gasoline mixture will explode prematurely when the engine piston is compressed, affecting the power of the car.

The biggest difference between the two gasolines is the difference in n-heptane and isooctane content. Among them, No. 92 gasoline is rich in 92% isooctane and 8% n-heptane; No. 95 gasoline is rich in 95% isooctane and 5% n-heptane. The difference between No. 2 gasoline and No. 95 gasoline is the difference in octane number.

No. 95 gasoline has a higher octane number, so it has better anti-knock performance. In fact, as far as I am concerned, the current 95 gasoline is equivalent to the original 93 gasoline, and the current 92 gasoline is the original 90 gasoline.

There is no difference between 92 and 95 gasoline in composition, the main difference is in the octane number. Number 92 indicates an octane rating of 92%, and number 95 indicates an octane rating of 95%. So what does this do for the engine?

The higher the oil gauge of the gasoline, the better the deflagration resistance. In addition, the gasoline mark also represents the anti-knock properties of the fuel. The larger the mark, the better the anti-knock performance.

It is worth mentioning that the grade of gasoline has nothing to do with the quality of the gasoline itself. It does not mean that the higher the grade, the better the gasoline, nor does it mean that the higher the grade, the fewer impurities or the purer.

92 gasoline is cheaper than 95 gasoline. Due to market competition and geographical factors, the price of oil is different at each gas station. For example, the gas station near the city center is in a good location and there are many people refueling.

Generally, ** will be a little higher. However, the price of gas at remote gas stations such as the suburbs will be lower. But no matter how the ** changes, at the same gas station, the ** of 92 gasoline is cheaper than the 95 gasoline.

The working principle of a gasoline engine is that when the piston is pressed to the top, the spark plug ignites the ** force generated by the air-gas mixture to push the piston.

In the process of injecting oil and gas into the cylinder and the piston going up, the temperature of oil and gas increases with the increase of pressure, and the temperature continues to rise. If the octane number of the added gasoline is not enough, many people used to think that 92 gasoline and 95 gasoline were just the difference in the purity of the oil. Now, more and more people know the difference between the octane number between them, because different octane numbers represent different anti-knock properties, and different anti-knock properties are suitable for engines with different compression ratios.

Different grades of oil have different octane number and knock resistance. The two can also be mixed and matched or interchanged, no problem at all. Some people say that high-grade oil has good power and good flame resistance.

I think it's just a psychological effect, it's all the same.

The combustion situation is different, the demand for the engine is different, ** is completely different, the use of gasoline in No. 95 is better, and the better cars use 95.

The proportion of isooctane in these two types of engine oil is not the same, 92 gasoline is only about 8%, 95 gasoline has reached 5%, if the proportion is relatively high, it means that the anti-knock performance of this gasoline is better, ** is different, generally 95 gasoline is more expensive.

They differ in knock resistance, isooctane content, and important characteristics of gasoline. 95 gasoline is a bit more expensive than 92 gasoline. Their classification is based on the way in which gasoline is produced.

The composition of gasoline is different, with different gasoline labels, and the anti-knock performance of No. 95 gasoline is better than that of No. 92 gasoline. The composition of gasoline determines different properties, and the octane number data is different, and there is an indication of the content of the components in this regard.

and 92 are both gasoline labels, representing the octane number of gasoline, the higher the octane number, the better the anti-knock resistance of gasoline.

The acceleration performance of No. 92 gasoline is very good, the power response is faster than that of No. 92 gasoline, and the vibration of the car is smaller than that of No. 92 gasoline, which should be good anti-knocking. And 92 gasoline on 2 days on the feeling of car performance decline, this everyone is very felt, after maintenance with 92 gasoline, the car performance continues to decline. And adding 95 gasoline can keep the car's performance from degrading.

With No. 92 gasoline, there will be a cold start sound that is not powerful, the power will be intermittent when cornering, and the acceleration will shrug a little. The most intuitive feeling is that the car is pulling a ton of goods, which has a sense of heaviness.
