Most BSVI vehicles with Selective Catalytic Reduction (SCR) equipment use AdBlue. According to the BSVI emission standards, all diesel cars must emit nitrogen oxide and diesel particulate matter, two hazardous pollutants.
With the help of a diesel particulate filter (DPF), a device made to significantly reduce diesel particulate matter or soot from diesel engine exhaust gas, and an after-treatment method called selective catalytic reduction, which uses the aqueous urea solution AdBlue to reduce harmful Nitrogen Oxide emissions, the emissions are controlled.
AdBlue transforms nitrogen oxides (NOx) into less dangerous nitrogen and water when it is added to exhaust emissions. Although the name “AdBlue” implies blue, the liquid itself is colorless.
High-purity urea (32,5%) and deionized water (67,5%) are the two main ingredients in AdBlue. You could see the lid of the separate tank for it next to the top of the diesel tank in the car.
AdBlue is injected into a catalytic chamber that is fixed in the exhaust pipe directly before the DPF when the engine is running thanks to a particular arrangement. The electronic control unit performs this procedure with the aid of sensors.
Every diesel engine that complies with the BSVI criteria must have a system to lower nitrogen oxide emissions. The Lean NOx Trap is used in small diesel engines (less than 2000 cc) (LNT). (LNT is a substitute for the SCR system, the AdBlue-using catalytic converter.)
A catalyst is LNT as well. Hyundai and Kia, manufacturers of small diesel engines, use it because of its low cost, ability to regenerate the catalyst, and low controllable NOx output. However, Mahindra uses AdBlue even in models with smaller 1500 cc diesel engines (such the Marazzo and XUV300).
AdBlue typically costs Rs 85. Depending on the brand, the price may increase or decrease.
The tank size for the catalyst in small diesel cars that employ AdBlue ranges from 5 to 20 liters. The car manual will provide the distance the vehicle has traveled since its last top-up. For instance, Toyota recommends topping off the 12-litre tank after 10,000 miles.
Is there a dashboard indicator for the AdBlue level? What transpires if the tank runs dry while traveling?
When the AdBlue tank is low, a dashboard warning signal on diesel vehicles will sound. The light will shine if the fluid reaches the reserve level. Along with the remaining distance that may be traveled, it will also display the anticipated distance when it will run out.
If AdBlue is over while the car is running, it won’t stop. The engine’s power is then decreased and emissions are managed by the electronic control unit. In limp home mode, the car will be driven for a while at this speed. Up until the next location where AdBlue is available, the vehicle may be operated in this mode. However, if the engine is turned off after AdBlue has finished, the AdBlue tank must be filled before the engine may be started again.

Do you have a question regarding diesel engines? If so, ADBLUE or any other DEF product is not used with diesel engines. For aftertreatment of the diesel exhaust, the exhaust system uses ADBLUE and DEF.
In addition, which nation do you refer to while discussing the use of the diesel engine’s aftertreatment?
You might not get a response because this is an old thread, and you might be restarting an old thread. Consider starting a new thread, please.

A Hyundai Tucson: Does it require AdBlue?
An illustration of a Personal Contract Purchase: Cash price PS10,000, deposit PS150, and borrowing PS8,500 for 4 years at a representative 7.4% APR (fixed). A total of PS4127.50 will be paid after 47 instalments of PS132.04. PS1833.38 is the total cost of credit. Payable in total is PS11,833.38. 8,000 miles per year as a base. If excess miles is used, there are fees. Finance subject to status; only those 18+.
All models in the Tucson line cost PS140 per year in road tax because prices range from about PS22,000 to PS35,000, but at least they don’t exceed PS40,000. The only option available is metallic paint, which costs roughly PS650, thus additional options won’t cause a significant departure from the list rates.
The Tucson engine lineup was updated in 2018 to include a smaller, more efficient version of the same-performing 1.7 CRDi diesel that nevertheless provides reasonable running costs. The new engines have been evaluated in accordance with WLTP law, which delivers worse economy results under test settings but produces outcomes that are more likely to be realized in the real world, therefore it is impossible to compare these engines like-for-like.
Efficiency in the 1.6 diesel versions has increased when the mild hybrid systems were introduced. On the WLTP test cycle, the 134 horsepower engine returns 48.7 mpg (manual) and 52.3 mpg (automatic), with CO2 emissions of 151 g/km and 141 g/km, respectively.
The 2.0 CRDi, the top model in the lineup, boasts a claimed fuel economy of 42.8 mpg, although due to the way the mild hybrid system operates, it doesn’t significantly improve the engine’s WLTP test economy. The estimated emissions are 172g/km.
AdBlue, which is used by all diesel Hyundai Tucsons to assist reduce emissions, has a 14-litre tank that will occasionally need to be topped off as needed, as indicated by the Tucson’s trip computer.
Surprisingly, the more potent 175bhp 1.6 T-GDi with the seven-speed DCT auto is the engine that is most efficient in petrol variants, with fuel economy ranging from 34.9mpg to 37.2mpg. With emissions of 173g/km, it also boasts the best performance.
AdBlue is used in passenger cars?
AdBlue requirements and SCR technology are becoming more typical for cars and other passenger vehicles. The majority of well-known automakers now offer vehicles with an SCR system that uses AdBlue.
Yara is the biggest producer of AdBlue in the entire globe. Since 2004, our AdBlue has helped to reduce hazardous emissions from so-called heavy-duty vehicles like trucks, coaches, and buses.
We provide packaged AdBlue in a range of formats for use in passenger cars. We provide AdBlue by Yara to drivers all over the world in collaboration with our Partners, who range from automakers and workshops to gasoline station forecourts.
We have made the decision not to speak with individual customers directly while collaborating with top shops. However, you may read about using AdBlue and the significance of AdBlue quality here. We are unable to respond to inquiries from specific automobile drivers.
How can I tell if AdBlue is in my car?
- the vehicle’s manual.
- Check to see if there is an AdBlue filler cap beneath the hood, in the boot, or next to the gasoline filler.
- if “Blue” or “SCR” are found in the model name.
- Ask a dealer if you aren’t sure if you are.
Is AdBlue required?
AdBlue is required to clean up the exhaust gases from diesel vehicles. Modern diesel engines needed AdBlue because of the implementation of Euro 6 emissions requirements, which mandated that they produce 80mg/km of NOx or less.
The new Euro 6d-TEMP test is even more demanding and intended to provide results from actual situations. Instead of doing it in a lab, measurements are taken while a car is being driven on the road using measuring equipment attached to the exhaust. The latter produced results that could hardly be repeated while driving.
Do all diesel vehicles require AdBlue?
If in doubt, refer to the vehicle manual. AdBlue should only be used in diesel vehicles equipped with an SCR system.
As a general rule, since the Euro 6 requirements were imposed in 2014, the more recent the diesel automobile is constructed, the more likely it is to use AdBlue. Here you may find the Euro emissions rating of your car.
For instance, all Land Rover diesel vehicles produced beginning with the 2016 model year are equipped with SCR technology, whilst AdBlue technology is used by Jaguar, Audi, Citroen, Peugeot, Mercedes-Benz, SEAT, Skoda, and Volkswagen.
Which diesel vehicles utilize AdBlue?
AdBlue is used in many diesel vehicles registered after September 2015 to cut emissions. The likelihood of AdBlue technology is higher if you drive a Euro 6-compliant diesel Audi, BMW, Citroen, Jaguar, Land Rover, Mercedes-Benz, or Peugeot. The model name of the car, which can include the words “Blue” or “SCR,” frequently contains a hint.
Hyundai Blue Drive: What is it?
Automobiles with Blue Drive are those that have fuel-efficient, emissions-reduced powertrains. The revolutionary powertrains that reduce fuel consumption and pollution are also described by Blue Drive.
When did AdBlue begin?
Although Tetrosyl introduced AdBlue under the Carlube name back in 2009, it has only lately come to the attention of many diesel drivers. However, many diesel drivers are still unaware of what AdBlue is, what it does, and why your diesel car needs it.
Why did Hyundai discontinue the i40?
Large family vehicle maker Hyundai from South Korea created the Hyundai i40 with the European market in mind. The 2011 Barcelona Motor Show saw the debut of the Hyundai i40 sedan, which shares a platform with the Hyundai Sonata sold in the US.
In other regions, including the United States, where the i40 is not available, the Sonata is nevertheless offered for sale as a distinct model. The Hyundai i40 was first offered as an estate/wagon in Europe and South Korea in September 2011, and then as a sedan in January 2012. It is also available in Australia and New Zealand.
At the 2013 Kuala Lumpur International Motor Show, Hyundai unveiled the i40 for Malaysia in both sedan and tourer configurations. The Hyundai Sonata is positioned underneath it. The two-liter GDI engine is mated to a paddle-shifted, six-speed automated transmission.
Early in 2019, the i40 was withdrawn in places including Australia and New Zealand due to falling mid-sized car sales globally, leaving the Sonata to fill the need. Since then, the i40 has been dropped in Europe as of 2020.
