What are the effects of gasoline and diesel being mixed together?

The specific gravity of gasoline and diesel is different, and after precipitation, the top is the diesel fuel below the gasoline.

First of all, the pressure of the diesel engine fuel injector is greater than the pressure of the fuel injector of the gasoline engine, after the diesel is added to the gasoline engine, due to the insufficient pressure of the fuel injector, the diesel can not be completely atomized, and can only be partially atomized, the consequence is that part of the diesel directly enters the cylinder in the form of liquid, the combustion is not sufficient, it is easy to accumulate carbon, and it will block the fuel injector, which is one of them.

The ignition point of diesel is low, and the ordinary gasoline engine is ignited by the spark plug, and after the gasoline engine is added to the diesel, before the spark plug ignites, the high-pressure mixture reaches the spontaneous ignition temperature and begins to burn violently, resulting in abnormal pressure in the combustion chamber, commonly known as detonation, which is the second.

As a driver, what you feel is that the engine is weak, the meat, stepping on the accelerator and not leaving, which is caused by insufficient combustion at the first point.

Then the engine shook abnormally, which was brought about by the second point of detonation.

It will bring irreversible damage to the engine, and even pull the cylinder in serious cases.

First of all, let's find out. There are a few main differences between gasoline and diesel:

First, there is a difference in density. Diesel has a high carbon content and high density; Gasoline has a low carbon content and low density. Therefore, we call diesel heavy oil and gasoline light oil.

Second, it is precisely because of the different carbon content that the two of them have different burning points. Diesel has a high carbon content, is easier to burn, and has a low ignition point, about 220; Gasoline, on the other hand, has a low carbon content and a flash point of around 420. That is, diesel is more likely to be burned, while gasoline is less likely to be burned.

Third, gasoline is more volatile due to its different volatility. Moreover, volatile gasoline is more likely to burn when it encounters fire; Diesel, on the other hand, is not easily volatile.

Then our gasoline engine and diesel engine will be designed according to the characteristics of the oil.

We all know that there is a component called a spark plug on our gasoline engine, which ignites the vaporized fuel, so why ignite? Because the ignition point of gasoline is high, it is not easy, so it is necessary to use a spark plug to ignite the gasoline mixture.

However, there is no spark plug on our diesel engine, and the ignition of the diesel engine is burned by compression. That is, the diesel engine will compress the vaporized diesel to a very small volume, compress the heat, so that it reaches its ignition point and burns. Diesel has a low ignition point, so it is more likely to be compressed and burned than gasoline.

Therefore, if we add diesel fuel to the gasoline engine, due to the compression of the engine piston, the diesel will also burn in advance, causing knocking and cylinder pulling. The piston has not yet been pressed to the top, but the diesel has already transmitted the power, as if, our athletes, when they are trying to do the final sprint, are about to reach the finish line, but suddenly a person rushes out and pushes you back from the front of you. This damage to the engine is very large.

Summary. Dear, I'm glad to answer for you Diesel and gasoline mixed together will produce the following undesirable phenomena:1

Damage to the engine. We know that gasoline and diesel do not have the same ignition point. The ignition point of gasoline is more than 400 degrees, and the ignition point of diesel is more than 200 degrees, in this case, spark plug pressurization will make the diesel with a low ignition point advance Then, eventually cause detonation, if it continues to drive after detonation, the engine will be overhauled or scrapped directly.

2.Carbon deposits are created inside the engine. The pressure of the fuel injector of the gasoline engine is not as strong as that of the diesel engine, which will make it difficult for the gasoline mixed with diesel to be completely atomized; Failure to fully atomize will result in less than adequate combustion in the cylinder, resulting in the eventual formation of carbon deposits.

Extended information, the difference between diesel and gasoline: 1. Gasoline is highly volatile, and diesel is difficult to volatilize, so there are fuel evaporation emissions in gasoline vehicle pollutants. 2. On the **, gasoline is more expensive, and diesel is cheaper.

3. Gasoline is easy to mix with air, and it is not easy to separate after mixing, the molecule of gasoline is smaller, and the mixing of diesel and air is uneven, and there is inevitably local hypoxia or local oxygen enrichment, oil is easy to carbonize to form carbon smoke when high temperature and hypoxia, and some odorous organic gases will be generated after diesel combustion, therefore, there is a smell in diesel engine emissions. 4. The energy of diesel is higher. Diesel does not need to be ignited, and spontaneously ignites at higher pressure, so it is more efficient, but it is very bulky and noisy.

Gasoline needs to be ignited, so the gasoline engine is smaller and quiet. 5. It smells different. Gasoline is pungent and diesel has a light smell.

6. The color is different, the gasoline is light, and the diesel is dark. In addition, diesel is mainly used in trucks, diesel engines are ignited by compression ignition, the compression ratio is high, can reach 15, the cylinder stroke is of course long, the engine torque is large, and the start and acceleration are more vigorous. Diesel engines do not rev very high, so the power is smaller than that of gasoline engines, and the speed is slow.

Gasoline is mainly used in cars, gasoline engines use ignition ignition, the compression ratio is not too large, generally self-aspirated in 8-11, supercharged will not exceed 14.

Summary. What to do if gasoline and diesel are mixed.

Hello, don't worry, I can ask for your question, but wait a minute, I need text for about 2 minutes.

Hello, gasoline and diesel are mixed, this is not used with Da Sou, you can use the ruler to clean parts, but the machinery and equipment, the engine can not be used, it will damage the engine, and the calendar must be cleaned The fuel tank must be cleaned, and the oil filter element can be replaced to prevent engine damage. Leads to greater losses. Hope mine is helpful to you.

What should I do if the gas and diesel are unmixed?

What to do with a lot of oil?

Hello, gasoline and diesel are mixed, this is not used with Da Sou, you can use the ruler to clean parts, but the machinery and equipment, the engine can not be used, it will damage the engine, and the calendar must be cleaned The fuel tank must be cleaned, and the oil filter element can be replaced to prevent engine damage. Leads to greater losses. Hope mine is helpful to you.

What to do with the mixed oil.

I want you to take a look at what I gave you. I've already told you.

There is no way to separate. You can only go to the 4S shop to unload the oil, clean the oil tank, oil delivery circuit and change the oil, so that the loss will be minimized.

Due to the different working principles of gasoline engine and diesel engine engine, in the gasoline engine, the gasoline sprayed by the fuel injector and the mixed gas composed of the air entering the throttle enter the cylinder, and then ignited by the spark plug when the compression stroke is near the end, producing the energy required to provide engine power output, which is called ignition.

The diesel engine uses the method of compressing air to increase the air temperature, so that the air temperature exceeds the spontaneous ignition point of the diesel, and then sprays the diesel, diesel spray and air are mixed and ignited at the same time, which is called compression ignition.

Therefore, the gasoline car is added to the diesel, once the car is started, due to the insufficient pressure of the fuel injector, the diesel can only be partially atomized, directly into the cylinder in the form of liquid, the combustion is not sufficient, it is easy to deposit carbon, and it will block the fuel injector.

After the gasoline engine is added to the diesel, before the spark plug is ignited, the high-pressure mixture reaches the spontaneous ignition temperature and begins to burn violently, resulting in abnormal pressure in the combustion chamber, commonly known as detonation, causing damage to the engine of the vehicle, and serious will cause the engine to pull the cylinder. Therefore, after the gasoline car is added to the diesel, do not start, quickly clean the fuel tank, and the problem is solved.

There is basically no solution, and if you have to separate, you can use fractional distillation, because the volatilization temperature of the two is different, but the device will be more complicated.

Thin film evaporator can, gasoline and diesel are originally hydrocarbons, can be completely integrated, their limit is mainly the boiling point temperature, the final distillation point temperature of gasoline is 205 degrees Celsius, and the initial distillation point temperature of diesel is 180 degrees Celsius, so as long as the evaporator temperature is controlled, gasoline and diesel can be separated.

However, if it is only gasoline and diesel, there is no kerosene fraction in between, and simple distillation is the most convenient. It uses the unit operation process of evaporating the low boiling point components and then condensing to separate the whole component by using the different boiling points of each component in the mixed liquid or liquid-solid system, which is a combination of evaporation and condensation.

Compared with other separation methods, such as extraction, filtration crystallization, etc., it has the advantage that no solvents other than the system components are used, thus ensuring that no new impurities are introduced.

Gasoline is volatile, but it already affects the quality of diesel. They dissolve into each other and can't be separated, if you add the wrong oil, you have to release the mixed oil from the tank, add a few liters of the right oil to clean it, and then add the right oil after it is released.

It's inseparable, but I want to add a whole thousand dollars of diesel, and fifty dollars of gasoline shouldn't affect it.

Then it depends on how much diesel you have in the diesel, if there is not much of it, let it go and re-add it, buy a lesson, gasoline and diesel can not be mixed.
