How many models of gasoline are there? What are the types of diesel and petrol?

Gasoline is divided into two categories: leaded gasoline and unleaded gasoline, and there is also an ethanol gasoline, and the common gasoline models are 89, 92, 95 and 98. Among them, No. 98 gasoline is the highest grade and the highest, also known as "noble gasoline".

The difference between different types of gasoline.

1. The octane number is different.

No. 89 gasoline contains 89% isooctane; No. 92 gasoline contains 92% isooctane; No. 95 gasoline contains 95% isooctane; No. 98 gasoline contains 98% isooctane.

2. The anti-explosion performance is different.

The higher the label of gasoline, the higher the isooctane content, and the stronger the knock resistance.

3. The applicable compression ratio is different.

The higher the engine compression ratio, the higher the gasoline model. Generally, the engine with the above compression ratio should use 92 gasoline; The compression ratio of the engine above should be 95 gasoline; The engine with the above compression ratio should use 98 gasoline.

4. The applicable models are different.

92 gasoline is suitable for ordinary cars with low technical content, 95 gasoline is suitable for the vast majority of cars, and 98 gasoline is suitable for luxury cars and sports cars.

The oil from the gas station generally comes from the refinery, and the oil refinery refines the oil excavated from the oil field into gasoline, which is transported to the oil depot by pipeline, oil tanker or train, and then the oil depot is pulled to the gas station by tank trucks, stored in the underground warehouse of the oil station, and pumped by the oil pump when refueling.

Since oil is generally cheaper at private gas stations, many people feel that there is a problem with oil. In fact, private gas stations are directly purchased from the oil refining company and sold, and there is no difference in the price of oil depot purchases, so the oil products are qualified and cheaper. However, it is not excluded that there are some black-hearted merchants who may be counterfeiting, but this situation is a minority.

The types of gasoline are: China IV: No. 90, No. 93, No. 97; Country V:

No. 89, No. 92, No. 95, No. 98. Gasoline is prepared by blending different gasoline components such as straight-run gasoline components, catalytic cracking gasoline components, and catalytic reforming gasoline components obtained from petroleum refining with high-octane number components, and is mainly used as fuel for automobile ignition internal combustion engines. The gasoline component can be divided into:

Straight-run gasoline, hot-cracked gasoline, catalytic cracking gasoline, catalytic reforming gasoline, superimposed gasoline, hydrocracking gasoline, alkylated gasoline, synthetic gasoline, etc., can be divided into aviation gasoline, vehicle gasoline, and solvent gasoline according to their uses.

At present, there are several types of gasoline: 90, 92, 93, 97, and 98.

The significance of the label is: the higher the grade of gasoline, the stronger its anti-knock performance, which has nothing to do with the quality of the oil. So what is knock resistance?

The engine is powered by a piston movement in the cylinder, and in the cylinder, the spark plug carries out the piston movement, and the gasoline and air are mixed and compressed. If the pressure is too high, there will be a deflagration and the engine will not work properly.

Gasoline contains a substance called isooctane, which acts as an anti-riot agent. For example, No. 92 gasoline contains 92% isooctane, and No. 95 gasoline contains 95% isooctane.

What is the difference between 93 gasoline and 97 gasoline.

The difference between No. 97 gasoline and No. 93 gasoline is the level of octane number, No. 97 unleaded gasoline has a higher octane number and is not easy to cause deflagration, and high-octane gasoline is generally suitable for engines with high compression ratio. If the manufacturer of your car requires the addition of 97 gasoline, it is recommended that you do not use low-grade gasoline to avoid knocking.

The so-called fuel label is the volume percentage of isooctane contained in the fuel. The higher this value, the better the knock resistance of the fuel. Generally speaking, if the compression ratio is below the 93 gasoline, if the compression ratio is greater than 97 gasoline, if it is larger, you need to use 98 gasoline.

The back of your car's fuel cap will be marked with the fuel number that needs to be added, just look at it.

Common gasoline models are 89, 92, 95, and 98.

First, the model of diesel oil has: diesel according to the condensation point classification, light diesel oil has six grades, -10, -20, -35, -50, heavy diesel oil has three grades.

The difference of each diesel model: diesel is divided into two categories: light diesel oil (boiling point range of about 180-370) and heavy diesel oil (boiling point range of about 350-410). The most important thing in the performance of diesel is ignition and fluidity, and its technical indicators are cetane number and freezing point, and the sulfur content is required to be controlled in the current specifications of diesel in China.

2. The types of gasoline are: gasoline is produced and sold according to the brand, and the brand specifications are specified by the national gasoline product standards and related to different standards. At present, there are 3 gasoline grades in China (IV), namely No. 90, No. 93 and No. 97.

Countries (v) are No. 89, No. 92, and No. 95 respectively (No. 98 in the Appendix).

Differences between gasoline models: Gasoline grades are classified by octane number. For example, No. 97 gasoline refers to gasoline fuel with antiknock properties equivalent to 97% isooctane and 3% n-heptane. The larger the marker, the better the anti-explosion performance.

Different grades of gasoline should be selected according to the different engine compression ratios, which will be indicated in the instruction manual of each vehicle. In general, No. 90 (China IV) gasoline should be used for mid-range cars with compression ratios between them, and No. 93 (China IV) gasoline should be used for cars with greater compression ratios.

There are two types of motor gasoline: leaded gasoline and unleaded gasoline, and there is also an ethanol gasoline, and the common gasoline models are 89, 92, 95 and 96. Among them, No. 98 gasoline is the largest model and the most expensive, and is also known as "royal car gasoline".

The difference between different models and specifications of motor gasoline.

1. The octane number is not the same.

No. 89 gasoline contains 89% isooctane; No. 92 gasoline contains 92% isooctane; No. 95 gasoline is 95% isooctane; No. 98 gasoline contains 98% isooctane.

2. The anti-explosion performance is not the same.

The higher the model of motor gasoline, the higher the isooctane content, and the stronger the knock resistance.

3. The available compression ratio is different.

The higher the compression ratio of the car engine, the higher the specified gasoline model. Generally, the automobile engine with a compression ratio above should use 92 gasoline; The engine of the car with a compression ratio above it should use 95 gasoline; The engine of the car with a compression ratio above it should use 98 gasoline.

4. The available cars are not the same.

92 petrol is suitable for lower-tech cars, 95 petrol is suitable for most vehicles, and 98 petrol is suitable for luxury cars and supercars.

The oil of the gas station is generally made from the chemical plant, and the chemical plant refines the oil and gas field excavation into vehicle gasoline, which is transported to the petrochemical plant by economic management road, freighter or train, and then the petrochemical plant pulls it to the gas station according to the truck, stores it in the underground warehouse of the gas station, and extracts it according to the gasoline pump when giving oil.

Because the oil in private gas stations is widely available and more cost-effective, many people feel that there is a problem with oil. In fact, the gas station of private enterprises can directly take the goods from the refinery enterprises and sell them in the market, and there will be no price difference between the petrochemical plants in the middle, so the refined oil is in line with the standard and more cost-effective. However, it is very likely that some black-hearted merchants have cheating, but these situations are very rare.

Millions of car purchase subsidies.

There are four models of gasoline.

The four models of gasoline are No. 89, No. 92, No. 95, No. 98.

Gasoline marking refers to the ratio of actual gasoline to standard gasoline anti-knock performance. The higher the label, the stronger the explosion-proof performance. Standard gasoline consists of isooctane and n-heptane. It's not that the higher the number, the better the gasoline.

It is necessary to choose a reasonable gasoline label according to the engine compression ratio of your own model. Use 90 gasoline with a compression ratio of the following, 93 or 95 gasoline with a compression ratio between , 95 or 97 gasoline with a compression ratio between , 97 or 98 gasoline with a compression ratio between , and 98 gasoline with a compression ratio between .

The quality of gasoline has a great impact on the car, causing damage to the engine, and a considerable number of cars have abnormal failures, which are the reasons for the use of inferior gasoline.

Most of the impurities in counterfeit and shoddy gasoline exceed the standard. When a car engine is running, low-quality gasoline fills the fuel supply system. Parts with small holes or filtration functions, such as oil pump filters, gasoline filters, and fuel injectors, are easily clogged by impurities in inferior gasoline, resulting in poor oil supply and reduced engine function.

Impurities in gasoline are generally present in gasoline in the form of colloids. Even if they pass through the filtration, they can be deposited in the intake valves, intakes, and cylinders, and the formation of hard carbon deposits can cause engine damage over time.

Gasoline containing impurities cannot be fully burned, which directly leads to poor exhaust and weak acceleration during driving.

Common gasoline models are No. 89, No. 92, No. 95, and No. 98, among which:No. 98 gasolineThe highest level is also the highest.

No. 89 gasoline contains 89% isooctane; No. 92 gasoline.

Contains 92% isooctane; No. 95 gasoline.

Contains 95% isooctane; No. 98 gasoline contains 98% isooctane. The higher the gasoline grade, the higher the isooctane content and the stronger the knock resistance.

Different gasoline models have different requirements for the compression ratio of the car. Engine compression ratio.

The higher the requirements, the higher the requirements for the gasoline model. Engines with compression ratios above generally use 92 gasoline; The compression ratio of the engine above should choose 95 gasoline; Engines with compression ratios above should run on 98 gasoline.

92 gasoline is suitable for ordinary cars with low technical content, 95 gasoline is suitable for most cars, and 98 gasoline is suitable for luxury cars and sports cars.
