Do foreign gasoline add isooctane, and is gasoline isooctane?

Fuel additives.

Fuel additives have two main functions, one is to clean the oil circuit, and the other is to increase the octane number.

If it is an additive for cleaning function, it is reasonable to add ** additives, it can clean some slight carbon deposits, at most it is to restore the normal fuel consumption of your car, it is impossible to say that it saves 5% of fuel, and it is impossible to improve in terms of power.

Increasing the octane number is used for example, if your car needs to use 95 oil, 93 will detonate, and it can only be added to 93 temporarily, so you can add a little additive to deal with it. However, it should not be used frequently. And when adding, it is best to add additives when the oil is almost empty, and then add oil, so that the mixture will be more even.

In short, when the car is old, you can add some regular original cleaning additives; And additives that increase the octane number are dealt with when they have to deal with it.

It's not easy to play by hand. If it helps you, please give it to me.

Problem description: Thank you. Analysis:

A lot of 97 gasoline is actually made by adding additives such as isooctane, cumene, alkyl auspicious benzene and MTBE antiknock agent to 90 gasoline, not by improving the processing technology of catalytic cracking and secondary reforming in the production process. 97 The high price and high profit of oil have fostered the culture of abuse of additives in some enterprises. They unscrupulously increase the octane number of gasoline, completely ignoring the comprehensive use of oil in other aspects, which has caused a considerable part of 97 gasoline to easily cause carbon deposits in the engine, and even the parts are corroded.

At present, these phenomena are more common in some imported high-end cars, as well as models with ultra-high compression ratios, such as the Polo, Palio and Sienna's recently released SpeedGear series.

Gasoline is distinguished by the octane number, which is an indicator of gasoline's anti-knock ability. There are two commonly used octane number measurement methods: the motor method and the research method, and the values measured by the two methods are different.

According to the value measured by the research method in China, No. 93 gasoline indicates that its octane number is not less than 93, and so on. The engine uses different grades of gasoline according to the different compression ratios, and if the engine with a high compression ratio uses low-grade gasoline that is not suitable, it will cause detonation.

There are two main ways to increase the octane number of gasoline: one is to add an antiknock agent to gasoline, and the other is to use a gasoline refining process containing high-octane hydrocarbons. In general, there are three ways for a plant to increase the octane number of gasoline:

The first is to select good raw materials and improve processing technology, such as catalytic cracking, reforming and other secondary processing technologies.

The second is to introduce high-octane components with excellent knock resistance, such as isooctane, cumene, alkylbenzene, etc., into the product.

The third is to add antiknock agent.

Adding a small amount of high-efficiency antiknock agent to gasoline can greatly improve the antiknock resistance of low-octane gasoline, and it is also the most economical way to obtain high-octane gasoline, especially when the processing and blending process is not enough, adding antiknock agent has become an effective way to adjust the octane number of gasoline. However, in practical application, there is a problem of high cost of antiknock agent. The most effective is the manganese-based organic compound antiknock agent (MMT), but because of the high cost and the need to add greater costs in the exhaust gas filtration device, it is not used with caution in China.

What is more used in China is an organic antiknock agent referred to as MTBE. The disadvantage of this antiknock agent is that it makes gasoline easily absorb water, so it is difficult to control it in use, storage and transportation. In other words:

The more MTBE is added, the more moisture will be in the oil, which not only has low combustion efficiency and insufficient power, but also is more likely to corrode the engine. It is this problem that is prevalent in our current 97 gasoline.

No, isooctane is used as an additive in motor gasoline and aviation gasoline. Butadiene is used as a solvent during polymerization, but cannot be used as a substitute for gasoline. Isooctane is a reference material for testing the anti-knock performance of gasoline. The octane numbers of isooctane and heptane are specified as 100 and 0, respectively.

If the anti-knock performance of a gasoline sample in a single-cylinder engine is equivalent to a certain component of an isooctane-heptane mixture under specified test conditions, the octane number of the sample is equal to the volume percentage of isoheterane in the standard fuel. Gasoline with good anti-knock performance has a high octane number. It is used as a standard fuel for determining the octane number of gasoline.

It is used in organic synthesis and as a comparison sample for solvent and gas chromatography. It has good shock resistance when burning in the cylinder of an internal combustion engine, and is an excellent engine fuel. It is a standard fuel for measuring the octane number (shock resistance) of gasoline, and is mainly used as an additive for gasoline and aviation gasoline, as well as a non-polar inert solvent in organic synthesis.

It is used in organic synthesis and as a comparison sample for solvent and gas chromatography.

Summary. The addition of isoprene to gasoline is good for the engine. <>

Isoprene can improve the anti-knock performance of gasoline, improve the combustion performance of gasoline, prolong the service life of the engine, reduce carbon deposition in the combustion chamber, reduce engine wear, improve the efficiency of the engine, improve fuel economy, reduce automobile exhaust emissions, and contribute to environmental protection. <>

What happens when isopentylene glycol is added to gasoline.

Hello dear! I'm glad to answer for you Asking Yuluo to add isopentylene glycol to gasoline can improve the thermal stability and anti-knock resistance of the balance residual oil, and improve the wear resistance and anti-oxidation resistance of gasoline, so as to make the use of gasoline more safe and reliable. <>

<> isopentylene glycol is an organic compound, which is a hydrocarbon blind compound composed of three carbon atoms and eight hydrogen atoms, with the molecular formula C5H12O2. The addition of isoamyl limb glycol to gasoline can improve the thermal stability and anti-knock properties of gasoline, as well as the anti-wear and anti-oxidation properties of Mobi potato gasoline. <>

<> isopentylene glycol can improve the wear resistance of gasoline because it can form an anti-wear film that can prevent the formation of deposits and water vapor in gasoline, thereby extending the life of gasoline. Isopentylene glycol can also improve the antioxidant activity of gasoline, because it can inhibit the oxidation reaction in gasoline, thereby prolonging the service life of gasoline. <>

Isopentylene glycol can also improve the thermal stability of gasoline because it can inhibit the thermal decomposition reaction in gasoline, thereby reducing carbon deposits in the combustion chamber of the engine, and can also improve the anti-knock resistance of gasoline rubber to prevent gasoline from high temperatures**. <>

Can it make gasoline better.

Yes dear. Is the addition of isoprene to gasoline good for the engine.

The addition of isoprene to gasoline is good for starting the answering machine. <>

Isoprene can improve the anti-knock resistance of gasoline, improve the combustion performance of gasoline, prolong the service life of the engine, reduce the carbon deposition in the combustion chamber, reduce engine wear, improve the work efficiency of the engine, improve the fuel economy, reduce the cracking of automobile exhaust emissions, and is conducive to environmental protection. <>

As a solvent, the oil is diluted, the combustion rate is improved, and it is easier to ignite.

Gasoline is made by refining different gasoline components such as straight-run gasoline components, catalytic cracking gasoline components, catalytic reforming gasoline components and other different gasoline components obtained from petroleum refining, which are prepared by blending with high-octane number components.

The common steam buried balance oil is generally white and transparent liquid, and some also show light yellow, which exudes a special liquid aromatic smell. Most of the commercial gasoline on the market is distinguished by the advantages and disadvantages of the anti-knock and combustion performance of the oil when it is burned in the gas fiber cylinder, and the advantages and disadvantages of the gasoline are determined. Gasoline is made up of a lot of substances, so that's where a gasoline filter comes in handy.

In order to prevent the gasoline from expanding and bursting the tank, there is usually a vent. If the oil is too full, the gasoline will spill out of the vents, which is not only expensive but also dangerous.

1.The composition is different: isooctane is a colorless transparent liquid with a melting point and a boiling point. Solubility: insoluble in water, soluble in ether, soluble in alcohol, acetone, benzene and chloroform; Gasoline is a volatile and flammable hydrocarbon mixture liquid that is fractionated or cracked from petroleum.

2.Different roles: isooctane is used in organic synthesis as a comparison sample for solvent and gas chromatography; Gasoline is mainly used as an internal combustion engine fuel for spark ignition, mainly including organic compounds and various additives obtained by fractionation.

Effect of adding isooctane to gasoline:

1. Sulfur reduction: reduce SOX emissions and prevent catalyst poisoning of tail gas converter. The HC, CO, NOX and toxic substances in the exhaust gas were reduced by % and 16%, respectively.

2.Olefin reduction:
