What should I do if a small amount of urea is added to the diesel tank?

With the technology of automobile production.

The development of diesel vehicles must use urea, because China's cars are mainly gasoline vehicles, diesel vehicles are basically in the form of trucks or trucks, diesel vehicles need to use urea, mainly to reduce car exhaust.

Emissions pollute the environment.

Urea used in diesel vehicles is mainly used to remove nitrogen oxides from exhaust gases.

Catalytic reduction into harmless nitrogen and water discharge.

There will be a urea indicator on the dashboard of the car, and it will also show the use of urea, when the car uses urea.

When the balance is less than about 20%, an alarm will be issued to remind the driver to add urea in time.

The amount of urea used in vehicles is about 3%-5% of that of diesel, and the urea used in diesel vehicles is made of high-purity urea and deionized water.

composition. In the process of using the car, the added urea will continue to be consumed, when the remaining amount of urea for the car is less than about 20%, it will be prompted on the dashboard, if not added in time, it will affect the power of the car.

In general, diesel has a flash point of 220 degrees Celsius.

The ignition point of gasoline is around 427 degrees Celsius. Gasoline is more flammable, so it is equipped with a gasoline engine.

The car will be a little easier with a cold start.

According to the different freezing points of diesel, diesel is divided into six grades: 10, 20, 35 and 50. Depending on the engine compression ratio, gasoline is divided into .

Hello If the proportion of addition is relatively small, it will not cause much impact on the engine, once the proportion of urea added is more than 2%, the car fuel tank should be cleaned, if the engine starts, the oil circuit must be cleaned, the impact on the engine is still very large.

The urea itself is injected into the exhaust pipe to react with the nitrogen oxides in the exhaust gas, so the diesel in the urea tank will not affect your engine, I don't know how much you add, if it is too much, it will burn or react in the high temperature environment of the exhaust pipe, which will affect your urea nozzle and aftertreatment system. If the amount is really a little bit, the impact should not be large. If you are not at ease, empty the urea and refill it.

It's okay that it's not much, the diesel engine has an oil-water separator, and the oil-water separator is discharged more after a while.

Consequences of mistakenly adding diesel fuel to the urea tank of a diesel car:

1. Diesel fuel and soot in the exhaust gas will slowly block the after-treatment system.

2. Diesel will burn in the exhaust pipe or even **. It is recommended to clean the urea tank and exhaust pipe immediately. If your vehicle has been running after adding diesel, it is possible that the reprocessed catalyst carrier has been scrapped.

Its working principle uses urea solution to react with NOx redox to generate N2, which is non-toxic to the human body, and emits it into the atmosphere. The urea pump is to pump the urea solution out of the urea tank and transport the urea solution to the nozzle through the delivery pipeline.

The urea pump is the core component of the SCR system, its performance is closely related to the emission function of the engine, in order to ensure the reliability of the urea pump to meet the working requirements of the SCR system, the urea pump needs to be calibrated.

The effect of purifying exhaust gases.

1. Urea for vehicles.

1. It mainly plays the role of purifying exhaust gas in the vehicle, and can react with nitrogen oxides in the exhaust gas to reduce nitrogen oxide emissions.

2. Vehicle urea can optimize engine performance and fuel consumption at the same time, and less diesel consumption can be as high as 5-7%. I have used a Baoyi brand of car urea before, and the fuel saving effect is not bad.

3. Urea is added to treat the NOx nitrogen oxides in it. Without urea, the exhaust gas emission cannot meet the standard.

Second, the use and function of automotive urea.

1. For cars, trucks, buses and heavy-duty off-highway diesel engine vehicles equipped with SCR (Selective Catalytic Reduction Exhaust Gas Aftertreatment) system, it can purify vehicle exhaust, reduce nitrogen oxide emissions in exhaust, and optimize engine performance and fuel consumption, reduce diesel consumption by up to 6%, and significantly reduce costs.

Second, diesel vehicles are best matched with vehicle urea, domestic well-known automotive urea brands mainly include Zhejiang Baoyi, Jiangsu KLS, Liaoning Rundi, etc.

It is impossible to say that there is a problem for more than one kilometer, because you can't determine the time when urea enters the engine, and you can't determine the time when the problem occurs.

If urea is accidentally added to the diesel tank, how far will it go if it runs? If you add urea to the diesel tank, you should not start the vehicle on the road, you should put the diesel fuel with urea on the spot, and then refuel it on the road, so that the urea will not enter the engine, and the engine will not fail.

It's okay that it's not much, the diesel engine has an oil-water separator, and more water has been discharged to the oil-water separator recently.

Urea accidentally added to the mailbox, added more than three barrels only to find that the car did not start all the oil in the mailbox was released, from the new oil on the road, not far to go the fault light on, after driving more than a day of the car is not good to start, what is going on? How can we deal with this?

Hello dear, I am happy to answer your questions, what to do if urea is added to the diesel tank.

What to do if urea is added to the diesel tank.

Hello dear, I am happy to answer your questions, what to do if urea is added to the diesel tank.

Urea is mistakenly added to the diesel fuel and needs to be cleaned immediately The urea tank and exhaust pipe need to be cleaned immediately, so as not to slowly block the processing system of the car in the soot in the diesel and exhaust gas, resulting in the combustion of diesel in the exhaust pipe of the car and even the first phenomenon. It is necessary to clean the urea tank and exhaust pipe immediately, disassemble the bottom of the urea tank, put the solution inside, replace the urea filter element, and clean it thoroughly.

Otherwise, the soot in the diesel and exhaust will block the car's treatment system, resulting in the combustion of diesel in the exhaust pipe of the car, and even the phenomenon of **, I hope mine can help you! I wish you a happy life<>

Summary. This situation is not possible, after adding diesel fuel to the urea tank, you must use tools to pump the urea in the urea tank clean, and then re-add qualified urea. You can use the endoscope to observe whether there is a deposit at the bottom of the urea, if there is a deposit, it must be cleaned, otherwise it will cause serious problems in the urea pump, urea nozzle and exhaust gas treatment system.

After the treatment is cleaned, the car can be used normally, and there will be no impact on exhaust emissions, the power of the vehicle and the service life.

You can use an endoscope to observe whether there is deposition at the bottom of the urea, but if there is a deposit, it must be cleaned up, otherwise it will cause serious problems in the urea pump, urea nozzle hole and exhaust gas treatment system. After it is cleaned, the normal use of the car will be Xinling, and it will not affect the exhaust emissions, the power and service life of the vehicle.

Does it matter if you add half a liter.

No, it must be cleaned up, otherwise there will be problems with exhaust emissions.

Which driver drove away.

If you can contact the driver, talk to him quickly and let him deal with it as soon as possible. Failure to do so will cause exhaust gas problems. Once the diesel fuel is injected into the exhaust pipe to participate in the combustion of the Bright Plum Bridge, it will cause the particle trap and the selective catalytic reduction to burn out or fail quickly.

Good. Even if you add four dollars, you can't do it.

It's okay, in this case, the diesel is floating on the urea, and it will take a long time to find out the problem. By then, he had already refueled the diesel many times, and he couldn't be sure which gas station he was talking about Liang Zhi.

It is very annoying to contact the monitoring to see the license plate number, and then report to the police station, and then help find the mobile phone number.

It's okay, let's do it first, don't worry about it. 4 bucks for diesel. Not a big problem.

Summary. Hello dear, you need to clean the urea tank and exhaust pipe immediately, disassemble the bottom of the urea tank, put the solution inside, replace the urea filter element, and clean it thoroughly.

Hello dear, you need to clean the urea tank and exhaust pipe immediately, disassemble the bottom of the urea tank, put the solution inside, replace the urea filter element, and clean it thoroughly.

Dear, when the urea tank is added to the diesel fuel by mistake, the only solution in this case is. Remove the urea tank, replace the urea, and clean the urea. If it is not treated, it is easy to block the urea pump and urea nozzle, and the maintenance cost will be higher.

Dear, it is not possible to add diesel fuel to the urea tank, you need to add diesel fuel and pump it out. Diesel and urea are incompatible, diesel will float on top of urea, you can park the vehicle for 3 or 4 hours, the diesel fuel on it is pumped out or all the urea in the urea tank is pumped out, and then replace the clean urea.

Summary. Diesel is below, and generally diesel is heavier, so burn urea first.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solution and solve the wisdom of the lease decision! If the urea grandson box is added with diesel, see how much you need to add to the blue chain, if you add a little, you don't have to worry, if you add a lot, you need to put urea. After the urea is cleaned, just add the urea again.

But how to deal with this kind of thing when the car is started.

Don't panic, just pump the urea clean first and then add new urea, and there will be no big problems after starting it for a long time.

Ok thanks.

Don't panic, it's not a big deal, it is recommended that you need to pump the urea clean before adding clean urea.

So is diesel and urea together oil on top and urea on top, and urea on the bottom?

Diesel is below, and generally diesel is heavier, so burn urea first.
