What is AdBlue? Why do we need AdBlue?

AdBlue technology is becoming popular in the field of new diesel-powered cars that reduce emissions. If your diesel car has been produced in the last few years, you may have seen a small secondary lid next to the oil tank lid (diesel). If the lid is marked with ‘AdBlue’ then your car is equipped with smart exhaust treatment technology. But in many Asian countries, you will hard to find a vehicle that is using Adblue because Asian still follow Euro 2 standards so Adblue is still an unfamiliar name for us. So what is AdBlue? Let know more interesting information about it in share category of Viknews.com.

What is AdBlue?

What is AdBlue?
In many Asian countries, you will hard to find a vehicle that is using Adblue

AdBlue is a copyrighted trademark registered by the VDA (The German Association of the Automotive Industry) for AUS 32 (Aqueous Urea Solution) compound – Urea solution 32.5%. This compound is used for selective Catalytic Reduction system (SCR) to reduce Nitrogen Oxide emission from diesel engines.

AdBlue is a high purity Urea solution and is completely removed from heavy metal components. AdBlue is non-toxic and very safe to handle. It neither explode nor burn and does not harm the environment. AdBlue is classified as the lowest risk category for transportable liquids. AdBlue is neither fuel nor fuel additive and needs to be contained in a dedicated tank. The using way of AdBlue is similar to refueling diesel/gasoline. If the liquid in contact with your hands, you just need to wash it with water.

Why do we need AdBlue?

Environmental standards are increasingly stricter for automobile manufacturers due to environmental issues. Euro 6 emissions standards begin to take effect in 2016 and will make a huge impact on diesel engines. In order to comply with the new regulations, car manufacturers had to focus on reducing harmful nitrogen-oxide emissions.

‘Selective catalytic reduction’ technology (SCR) is an effective method to bring diesel engines up to Euro 6 standards. It is used by many famous automobile manufacturers such as Audi, BMW, Volkswagen, and Mercedes. Mercedes with BlueTEC technology or Citroen BlueHDi all use SCR technology in conjunction with AdBlue.

What is AdBlue?
AdBlue is a copyrighted trademark registered by the VDA.

How does AdBlue work?

AdBlue is a non-toxic, colorless liquid with 2 main ingredients: distilled water and urea. To meet the Euro 6 standard, diesel-powered cars recently use SCR technology to inject this compound into the vehicle’s exhaust system. Urea solution combines with emissions to produce nitrogen gas and oxygen to be harmless to the environment by decomposing single nitrogen oxides (the main pollutant component of Diesel engines). This technology has been used in buses and heavy trucks for a long time, so its effectiveness and reliability has been proven.

Does your car use AdBlue?

SCR technology with AdBlue is becoming popular. If your car has recently been imported with US or European standards, it is possible that your car has applied AdBlue technology. Many people do not know this until the warning lights appear on the AdBlue additional notification panel. Because the SCR system has no effect on the operation of the vehicle, and there is no clock warning the remaining amount of AdBlue.

If you don’t know if your car uses AdBlue, then you can find out in the vehicle’s manual. You can check it to know the place of AdBlue cap. If it is not mentioned, your car may not equip SCR technology. If so, please check the exact location of the Adblue cap. Normally, the Adblue loader is next to the fuel feeder, but there are some cars that move this part to under the floor coverings.

What is AdBlue?
Normally, the Adblue loader is next to the fuel nap.

How to load AdBlue into the car tank?

If you need to move a long distance and are not sure about the amount of AdBlue remaining, you should check usually to avoid depleted AdBlue, which will affect the engine and SCR system as well as the vehicle exhaust system.

Adblue loading method is quite simple. The best way is to consult the manual of your vehicle, but usually, you just need to open the AdBlue side cap, then pour AdBlue into the container. In the case of large containers, it requires a connecting nozzle. You can buy a nozzle from any car’s equipment dealer if your container is too big. This will save you time for the Adblue pouring process and avoid spillage.

What is AdBlue?
AdBlue is a non-toxic, colorless liquid

Some vehicles require the use of wheel braces to wring the AdBlue bottle cap, and most require you to pour a relative amount (usually about three to five liters) when reloading, to stop the warning from AdBlue’s notification. Although not toxic, AdBlue is corrosive and can irritate skin, eyes, and lungs, thus you have to wash your hands after filling AdBlue.

When making international transactions, you will receive a request to enter the Swift Code from the bank. So what is Swift Code? What is this code used for? To better understand this issue, please follow the article below of Viknews.com

What is Swift Code?

Swift Code is an abbreviation for Society for Worldwide Interbank Financial which means an identification code intended to identify a bank or financial institution in the world. Each bank or financial institution will have a separate Swift Code to distinguish it from the remaining financial institutions and banks.

What is Swift Code?
What is Swift Code?

In addition, Swift Code is also known as BIC, which is the abbreviation for Business Identifier Codes. Therefore the Swift Code or BIC code has the same meaning. Swift Code usually has 8 or 11 characters, each character has its own meaning: Bank name, country name, branch code.

Advantages of Swift code

With the inheritance of the advantages of modern technology combined with strong financial potential, banks in the world are gradually developing and expanding markets, meeting increasingly high demands of customers.

Therefore, Swift code has been constantly improved and upgraded to serve the needs of international users. The advantages of Swift code include:

– The speed of information transfer is fast, allowing users to handle a large number of transactions.

– The transaction time is shortened, saving the maximum cost of use.

Swift code always has to follow uniform standards all over the world. When using Swift code in banks, you can join the world banking community. Knowing information about Swift code will help your transaction be conducted quickly and more conveniently.

What is Swift Code?
Each bank or financial institution will have a separate Swift Code

International convention on Swift Code code

In order to unify the form of Swift Code around the world, we have an international convention on the character arrangement of Swift Code. If any bank in the world does not comply with this law, their Swift Code will not be accepted.

International convention on Swift Code code is AAAA BB CC DDD. Which is:

– AAAA: The abbreviation in English of the bank name. This is a character that distinguishes banks and financial institutions around the world. With the first 4-character position AAAA requires the user to enter a character in the form of letters, from A to Z, without the use of numeric characters.

– BB: The abbreviated character in English of the country where the bank is located. Two BB characters are used according to ISO 3166-1 alpha-2. For banks in Vietnam, these two characters are always in Vietnamese form. Therefore, when looking at the Swift Code code, if it is found in the 5,6 positions, there is the word “VN” then it proves that this bank is in Vietnam.

– CC: Local identification code. These two characters allow users to enter both numbers and letters. CC codes are usually specified in VX format.

– DDD: A code that identifies a bank or bank branch participating in a transaction. This character allows users to enter numbers and letters.

Thus, Swift Code bank in Vietnam is in the form of AAAAVNXDDD. For example, BIDV branch of Cau Giay branch in Hanoi will have Swift Code code is BIDVVNVX215.

What is Swift Code used for?

Swift Code is a code snippet that requires you to enter when performing international transactions, payments, transfers and payments. As the information above, Swift Code will share with you informations about what the bank name is, which country the bank belongs to, where its branches are located and the specific address of each branch.

This will bring convenience to the transaction process of customers, help you perform transactions, make payments, transfer and receive money correctly, avoiding errors in the process of implementation. Besides, Swift Code will help the transaction time happen faster, minimize transaction costs for customers.

In Vietnam, the code Swift Code usually uses 8 characters. The 11-character type will have additional branch codes, while a bank usually has a lot of branches, making it difficult for users. So compared to the 11-character type, 8-character Swift Code code has many advantages, making it more convenient for users to perform.

What is Swift Code?
Some Swift Code of banks.

According to the experience of customers in Vietnam, when transferring or receiving money from abroad to Vietnam, you should use Vietcombank or ACB because these two banks are quite convenient and the transfer buying rate is quite high if you want to convert into VND. In case you withdraw USD, after 10 days money will be returned to the bank for free. So, if you want to make a transaction in international scope, you need to know what Swift Code code is to avoid confusion with other banks or organizations in the world.

What is dab ratio? Advantages of dab technology

“Dab ratio” is definitely an unfamiliar definition for many people. So today, Viknews.com will share with you the basics of DAB – Digital Audio Broadcasting, a form of radio technology that is being used in many countries around the world. Let’s read the following article to answer the question what is dab ratio and find out what is advantages of dab technology.

What is dab ratio?

Dab ratio’s definition

DAB Digital Radio, also known as digital audio broadcast, is a completely new system for broadcasting and receiving stations.

What is dab ratio?
What is dab ratio?

As its name, signals broadcast in a digital format allow CD quality to be achieved. Those who have listened to the digital radio DAB have commented on the significantly better sound quality and “presence” of the new radio system. Also, it does not suffer from the multiple effects often experienced on FM transmissions and the system uses what it is called a single frequency network (SFN) without having the necessary retuning when moving from a next coverage area.

In addition, many new services can be implemented on digital radio stations that allow new systems to fit into the 21st century. Digital radio signals carry data along with sound, and this allows text and images to be transmitted with sound to enhance the listening experience. In this way, it can convey the title of a song, and a photo of the artist while some music signal is being transmitted. It can also move news on the bottom of the screen used on radio stations. DAB digital radios are now established in many countries around the world from the United Kingdom and Europe to Canada, Australia and many other countries.

The digital dab ratio construction

In order to produce a digital system that satisfactorily operates according to the conditions required for digital radio, a large number of jobs have been performed during the development phase. A number of current digital techniques have been studied but it has realized significant limitations for this application.

What is dab ratio?
DAB technology makes digital radio become a reality

One of the main problems is that many recipients will use non-directional antennas and as a result, they will receive a reflected signal. These will be delayed enough for the faulty data. Also, the bandwidth required to accommodate a full stereo signal will need to be reduced to ensure efficient use of the spectrum.

The technical standards for digital radio were developed under the auspices of the European Eureka Project 147. The group includes manufacturers, research stations and network operators. There are two main areas of the system that are interested in digital broadcasting: that is the modulation system and the digital audio coding and coding system.

The encryption and compression system is very important for the system to be able to develop data rates that have been significantly reduced compared to standard CDs. Digital radio system adopts a data rate reduction of 128 kbits / sec, a sixth of the bit rate for quality is similar to the encoded linear signal to achieve input audio signal reduction be analyzed carefully. It is found that the ear can only hear a certain frequency threshold, if the sound is generated at a lower frequency then we will not be able to hear it.

Also if a high-frequency sound is played on a sound system, then the frequency is lowered, it may not be heard because the hearing threshold is modified. By analyzing the sound to and only encoding the components that the ear will hear, it will significantly reduce the amount of work to be done.

Advantages of DAB technology

Digital radio technology (DAB) promises to replace the analog technology with FM radio broadcasting in the near future because DAB technology was overcome many limitations of FM.

What is dab ratio?
DAB technology has overcome many limitations of FM.

To broadcast FM, radio stations use frequencies from 88 to 108MHz. These stations must have a certain distance to avoid wave conflict, so the number of FM radio channels is limited. FM also cannot transmit signals over long distances. Meanwhile, DAB allows stations to transmit information in digital media in much the same way that mobile networks operate, including data compression and multiplexing. DAB creates a very wide channel, about 1,500MHz, then splits this channel into multiple streams for different service providers.
