How much gasoline is suitable for modern cars, how much gasoline is good for cars now, why is there

In addition to the new Shengdajia No. 97 oil, Beijing Hyundai Motor's other 93 is enough ......

Depending on the alkane number, the label of gasoline is also different. The higher the alkane number, the higher the grade of gasoline. In a gasoline engine, if the cylinder volume is the same, the speed is the same, but the compression ratio is different, the output power is also different, the higher the compression ratio, the greater the output power.

In the engines produced, the higher the compression ratio, the more demanding the technical requirements. Gasoline engine different compression ratio, with different alkane number gasoline, the compression ratio is suitable for 92 gasoline in 8 to 9, the compression ratio is suitable for 95 gasoline in 11, a small number of imported cars with a compression ratio of 12, suitable for 98 gasoline [few on the market], all kinds of gasoline in the engine in advance ignition crankshaft rotation angle is different [there are more than 11 degrees, there are less than 9 degrees, the ignition angle in advance is large with low-grade gasoline, on the contrary, with high-grade gasoline], can not be used indiscriminately, so as not to damage the engine, so all kinds of [cars] The gasoline engine can only use the specified number of gasoline according to the manufacturer's instructions, and the high compression ratio cannot use high-grade gasoline, and the high compression ratio cannot use low-grade gasoline.

The higher the oil number, the better, the higher the number of oil, the cleaner the oil, 92 is the original 93, 95 is the original 97, the national standard has been changed.

According to the latest national standard, the original No. 93 was changed to No. 82, and the number of 97 was changed to No. 95, and 95 is the highest. 4S shop professional technician, 10 minutes to solve. 】

Gasoline is suitable for ordinary cars with low technical content.

For the models below 100,000 yuan on the market, No. 93 gasoline is their best partner, which is suitable for those models with mature engine technology and no excessive requirements for fuel requirements.

Gasoline is suitable for the vast majority of cars.

No. 97 gasoline is generally suitable for turbocharging and high compression models, and it can be compatible with most models on the market, whether it is a small car of tens of thousands of yuan or a high-end car of hundreds of thousands.

Gasoline is suitable for high-end luxury cars and high-horsepower sports cars.

Compared with No. 93 and No. 97 gasoline, the production of No. 98 gasoline will have higher requirements for technology and equipment, and China has only realized the domestic production of this brand of gasoline in the past two years. The anti-knock performance of No. 98 gasoline is undoubtedly the best of the three gasoline, and it is also the highest production standard.

At present, gasoline on the market has equal labels, and these numbers represent the octane number of gasoline, that is, the anti-knock resistance of gasoline, and have nothing to do with the cleanliness of gasoline. The claim that "high-grade gasoline is cleaner" is purely misleading. Refueling according to the compression ratio of the engine or the requirements of the car instruction manual is more scientific and economical, and can give full play to the efficiency of the engine.

No. 92 gasoline is 92% isooctane and 8% n-heptane.

The compression ratio of domestic cars is generally above 9, and it is best to use 92 or 95 gasoline.

No. 92 gasoline is suitable for ordinary cars with low technical content.

Gasoline 95 is suitable for the vast majority of cars.

98 petrol is suitable for high-end luxury cars and high-horsepower sports cars.

Gasoline marking BAI

It is the octane number of gasoline, the more.

DU represents the better the anti-explosion, the less easy to knock the cylinder, the smoother the work of the DAO machine, and the larger the compression ratio of the internal high-end hair and motor and the supercharging application, the greater the anti-explosion performance, the better. That is to say, 97 is the best, but 97 is the most expensive, and 93 is fine for general cars. Beijing's oil label is different from the rest of the country.

Octane 92.

This value doesn't make sense, you just add the number 93 or 92.

China's high-grade oil is made with two barrels of oil with antiknock agent, and the oil is very bad, it is better to go straight to 93.

The domestic ones are currently No. 93 and No. 97.

Previously 97 gasoline was added.

Suddenly, there is no problem with adding 93 gasoline, and the general car is better to add the dao gasoline of that mark. Look at the car gasoline label.

Method of answer sign:

1. Check the car instruction manual, which records the number of gasoline that the car should be filled with.

2. The fuel label will be indicated on the fuel tank cap, and it will be recommended how many gasoline you should fill, preferably with a few gasoline.

Usually bai says compression.

than in between the engine DU should be selected.

zhi90 dao93 gasoline; The compression ratio should be selected between the version of 90 93 gasoline; The compression ratio should be between 93 95 gasoline; The compression ratio should be between 95 97 gasoline, and these relevant data will be clearly indicated in the manual of each car, and everyone must read the manual carefully when buying a new car.

It is best to use gasoline that matches the label.

The higher the gasoline grade, the better, even if it is a high-end car, it does not mean that you must add high standard oil, and the right one is the best. Therefore, before refueling your car, you must carefully read the manufacturer's instructions and choose gasoline according to the instructions in the manual. Different engines have different compression ratios, which also determines the most suitable oil number.

If a car with a low compression ratio adds high-grade gasoline, it will waste fuel costs, and it will also cause the car to have "symptoms" such as slow engine ignition, easy exhaust valve burnout, and weak acceleration.

Fuel additives.

Fuel additives have two main functions, cleaning the oil circuit and increasing the octane number. Reasonable addition of ** additives is helpful to the car, but the premise is **, inferior additives may damage the vehicle, and it is meaningless to add more, and it may also affect the octane number.

The level of gasoline marking only indicates the octane number of gasoline, and the label must not be confused with purity and quality. Take No. 93 gasoline as an example, which means that its isooctane content is 93%, so it is named No. 93, and so on. Generally speaking, the higher the content of isooctane, the better its anti-knock performance, that is to say, the anti-knock performance of No. 97 gasoline is better than that of No. 93, if you want to make gasoline release more energy after burning in the combustion chamber, you need to increase the compression ratio of the engine to meet the characteristics of No. 97 gasoline with good anti-knock performance.

Therefore, the number of oil to add is determined according to the needs of the car, especially the engine compression ratio.

The car has specific requirements for the type of oil, such as the Polo car uses two engines: liter displacement BCC type and liter displacement BCD type, and their compression ratios are: liter BCC type, liter BCD type. Depending on the compression ratio, both engines were supposed to run on 97 gasoline.

Although it says that 93 oil can also be used in the manual, if conditions permit, do not add 93 gasoline in order to save money, because in terms of performance and protection of the engine, it is definitely more advantageous to use 97 gasoline.

Therefore, once again, car owners are reminded not to be misled by the "high-grade gasoline is cleaner" when refueling, and to add gasoline strictly according to the engine compression ratio or follow the recommendations on the car's instruction manual, which is more scientific, more economical, and can give full play to the power of the engine.

It doesn't matter if the car is numbered wrong, 97 gasoline. It's all the best. The lowest is 92 gasoline.

Usually, the fuel number is indicated on the fuel tank cap. The only criterion for selecting gasoline labels is the compression ratio of the automobile engine. Generally, the larger the compression ratio, the higher the gasoline grade.

In general, the compression ratio should be 90-93 motor gasoline; The compression ratio should be 90-93 vehicle gasoline; The compression ratio should be selected 93-95 car gasoline; The compression ratio should be 95-97 gasoline.

I work at Sinopec, and I'll answer that question. 97 and 93 are basically the same, but the purity is different, and the domestic oil is like this, so it has no effect. There is also the question of how much gasoline the car refuels.

This question should be written when buying a car. Please check it out for yourself.

The larger the compression ratio of the engine, the higher the gasoline grade required, if you use low-grade gasoline, it will lead to weak acceleration of the vehicle, carbon deposition in the engine, and occasional detonation, which has no great effect.

It's okay! 97 has nothing to do with 93! A large part of the population said that the No. 97 oil truck was boring

Just in case, you still use it according to the manufacturer's regulations.

Gasoline No. 92 is suitable for gasoline cars with engine compression ratios in between.

No. 92 gasoline is a gasoline with an octane rating of 92, which is suitable for mid-range cars (with a lower compression ratio). The engine compression ratio is the most important parameter in determining the choice of gasoline grade. Academically, there is no very uniform standard for what kind of gasoline to use for what compression ratio, and with the wide application of knock sensor and automatic adjustment of ignition advance angle technology, high compression ratio cars can also use relatively low grade gasoline.

At present, in the practice of the international automotive industry, the following oil standards are widely adopted:

No. 90 gasoline – for gasoline cars with an engine compression ratio or less.

Gasoline No. 92 is suitable for gasoline cars with engine compression ratios in between.

95 gasoline – for gasoline cars with engine compression ratios in between.

No. 98 gasoline - suitable for gasoline vehicles with an engine compression ratio or above.

No. 92 is shorter than No. 95 oil burning time, if the car with No. 95 oil is added with No. 92 oil, the combustion will be a little earlier, although it is only a little angle on the engine on a kind of impact, (there is also a possibility of detonation, the detonation is the oil number problem caused by spontaneous combustion) to the connecting rod, piston, crankshaft, etc. The car is made of No. 92 and added No. 95 oil, and there is no consequence, but some cars will increase fuel consumption (depending on the compression ratio). Add No. 92 oil for those with a compression ratio of 11 or less, and add No. 95 oil for those above it.

Let's talk about the compression ratio, the compression ratio is not simply said to be different combustion volumes, in fact, there are different ignition times. The ignition time of the No. 92 oil car will be delayed a little, and the ignition oil of the No. 95 oil car will be a little earlier, which involves mechanical construction problems. Therefore, don't add 92 oil to the car with 95 oil, in short, it will hurt the car.

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. The mid-range sedans with compression ratios between should generally use 92 gasoline; Cars with a compression ratio greater than 95 should use No. 95 gasoline. At present, the compression ratio of domestic cars generally uses 92 or 95 gasoline.

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. Engines with low compression ratios can be used with high-grade gasoline, which will have a corresponding increase in power (because the calorific value of 95 gasoline is slightly higher).

First of all, it depends on what kind of car you have, in simple terms, there are two kinds: one is expensive and the other is simple.

Usually divided by car: one is more than 300,000, and the other is less than 30.

Add 97 to the above and 93 to the below If you don't understand it, ask again.

It depends on the compression ratio of your car's engine! The larger the compression ratio, the higher the gasoline grade!

This mainly depends on the engine, and the car **, the car type has little to do with it.

Generally speaking, the economy family car is 93 (92), the luxury car 97 (95), and the supercar 98

Gasoline is expensive. Hundreds of thousands of cars can be added with both kinds of oil.

No. 92 gasoline is suitable for ordinary cars with low technical content.

No. 92 gasoline is suitable for models with less than 100,000 yuan on the market, mature engine technology and no excessive requirements for fuel.

Gasoline 95 is suitable for the vast majority of cars.

No. 95 gasoline is generally suitable for turbocharged and high-compression models, and it is compatible with most models on the market today.

98 petrol is suitable for high-end luxury cars and high-horsepower sports cars.

Compared with 92 and 95 gasoline, the production of 98 gasoline will have higher technical and equipment requirements. The anti-knock performance of No. 98 gasoline is the best of the three gasoline, and at the same time, it has the highest production standard.

Number 95 is expensive. Add a little better fuel to a car of more than 100,000 yuan, add No. 95 oil.

The higher the oil grade, the slower the combustion rate of the oil, the lower the combustion knock, and the higher the compression ratio of the engine;

On the contrary, the combustion speed of low-grade fuel is faster, the combustion knock is large, the engine compression is relatively low, the combustion speed of low-grade gasoline is fast, and the ignition angle should lag; The combustion rate of high-grade fuel is slow, and the ignition angle should be advanced.
