Petrol vs Diesel Problem 5, Gasoline vs Diesel Issue

Remember that the flash point of gasoline is 46, diesel forgot.

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.

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

Diesel: It is generally believed that this is the case, because of the strong smell of diesel combustion in history, there is black smoke, similar to burning firewood, so it is slowly called down.

Gasoline: First, it is relatively easy to vaporize. When the car was first invented, it was to burn steam and produce power, at this time it was called a car, and later, the car began to burn oil, let's call it gasoline, in fact, many things we are accustomed to are like this, and a deep study will find that it is often the most amazing reason, some habits. For example, why does electricity have "gas". The landlord can also check, which is very interesting.

Where did diesel fuel come from?

If the gasoline engine only adds a little diesel, it doesn't matter (no more than 8-10%), less diesel will not affect the work of the gasoline engine, normal driving is enough, let the 4s clean up the oil circuit during maintenance.

If the owner of the car is brainy or distracted by a beautiful woman when he is refueling, he will add half a tank or a tank of diesel fuel at once. Ahem, you have to pay attention, if you find that it is not started in time after adding the wrong oil, you can directly call the trailer to pull it to the repair shop to pump oil and then clean the fuel tank.

If it is launched, it will be more complicated, one by one.

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.

Most of today's engines are internal combustion engines, that is, fuel is burned inside the engine to convert thermal energy into mechanical energy. However, the fuel of the internal combustion engine is also divided into diesel and gasoline, both of which have their own advantages and disadvantages, but a guy abroad thought about what would happen if he mixed these two together and added them to the fuel tank.

How many are added! It's okay if it's rare! But the nose burns not very well! There will also be a bit of black smoke.

Clean the fuel tank immediately and clean the oil circuit.

Diesel vehicles are more fuel-efficient than gasoline vehicles, which is determined by the technical characteristics of the engine. Because the compression-ignition diesel engine has a higher energy conversion than the ignition gasoline engine, the energy consumption is 45%-60% of the gasoline engine, and the diesel ** is lower than the gasoline**, the engine has less complex high-pressure ignition device than the gasoline engine, and the life is generally longer than the gasoline engine product, so the fuel economy of the diesel engine is better than that of the gasoline engine.

At the same time, diesel engines also have outstanding advantages over gasoline engines in terms of safety and environmental protection.

Diesel fuel is not volatile, has a high ignition point, and is not easy to be ignited or occur due to accidental circumstances**; The emission of carbon dioxide is also about 30%-35% lower than that of gasoline engines, and the exhaust emissions of diesel vehicles are better than those of gasoline vehicles.

In addition, the diesel engine is also very small in terms of power and gasoline engine, some performance parameters are even better than gasoline engine, for example, the low-speed torque of diesel engine is relatively large, which is reflected in the diesel car climbing ability is stronger than gasoline car, and the acceleration at low speed is faster than that of gasoline engine.

At present, the diesel quality in most parts of the country simply cannot meet the requirements of the latest Euro III and IV emission standards for diesel engine technology, and the fuel with higher sulfur content will not only lead to the deterioration of the diesel vehicle emission system, but also shorten the engine life and increase the repair and maintenance costs.

In addition, most of the domestic consumers' awareness of modern diesel engines is still very low, and most people still stay in the 70s of the last century on the understanding that the black smoke is billowing and the noise is unbearable, and there will be great resistance to diesel cars. With the development of new diesel engine technology, diesel vehicles have made great progress in exhaust emissions and noise reduction.

The biggest difference is that diesel cars burn oil more economically than gasoline, and it is not easy to break, but it costs a lot of money when it is broken, and most of the domestic repairmen are not very good at the technology of diesel cars.

The structure of the gasoline engine is more complex, while the diesel engine eliminates the ignition system (high-voltage wire, ignition coil, spark plug, etc.).
