Let's Speak AdBlue

With BS VI emission norms now in place as a mandate in India, many vehicle manufacturers have embarked on adding AdBlue® or Diesel Exhaust Fluid requirement in diesel vehicles. 

The ownership experience of a diesel vehicle is expected to see a change with the switch over from BS IV to BS VI.  Terms like SCR and DPF technology have become common with the new diesel vehicles. 

With AdBlue® as an essential requirement for a diesel vehicle, let’s understand the above terms and the use of AdBlue®.

AdBlue®

What is AdBlue®?

Simply put, AdBlue® is a 32.5% solution of urea in deionized water and is required by many commercial vehicles operating on Indian roads. AdBlue® is essential for the correct operation of an advanced pollution control technology installed in the exhaust system called Selective Catalytic Reduction or SCR. 

Unlike diesel, AdBlue® is a clear, non-toxic liquid that is safe to handle and does not damage the environment. 

Please note: AdBlue® is not a fuel or a fuel additive.

AdBlue® is a high specification solution and is manufactured to the DIN 70070 and ISO 22241 standards.

What is SCR technology?

SCR, or Selective Catalytic Reduction, is an emissions control technology. It was first employed on coal-fired power stations to clean oxides of nitrogen (NOx) from the exhaust gasses. In 2006, the technology successfully crossed into the European heavy-duty diesel market, where it enabled trucks to meet the Euro IV and V limits.

An SCR system uses AdBlue®/ Diesel Exhaust Fluid and a vanadium or base metal catalyst mounted in the vehicle's muffler/ Exhaust to reduce NOx to water vapor and atmospheric nitrogen. This reaction takes place downstream of the engine in the exhaust system and is known as "after-treatment". Having the engine set up for maximum efficiency allows for an estimated fuel saving of 3-5%, giving operators the opportunity to save thousands on their annual diesel fuel bills.

What is DPF technology? 

Diesel Particulate Filter (DPF) is a device that physically captures diesel particulates to prevent their release in the atmosphere. One of the effective technologies for the control of diesel particulates emission. 

Usually, diesel vehicles with smaller engine capacities use DPF as an alternative for SCR technology. However, the diesel particles can accumulate at the exhaust in certain conditions like frequent short distances journeys, heavy traffic, or driving at a low speed for a long time. To ensure these particulates are burnt off, one is required to drive at speed higher than 50km/hour for approximately 30 minutes or revving the engine at a higher RPM for few minutes until the DPF indicator turns off.
