Total’s new AdBlue

In the ever growing battle with environmental pollution, car manufacturers are required to meet the latest standards for exhaust emissions and other pollutants. This has meant that car manufacturers have had to reduce emissions as much as possible. They have done so with the help of an additive called AdBlue, which is a water/urea based operating fluid which can be filled up the same way that screen-wash is topped up.

The AdBlue additive is stored in a tank, in the vehicle which is injected into a specially modified part of the vehicle’s exhaust. When added it begins a chemical reaction which removes the polluting oxides of nitrogen (NOx), converting them into harmless water and nitrogen which is a process known as Selective Catalytic Reduction (SCR).

This has led to the announcement from Total Lubricants that it is developing an additive that will dissolve in its AdBlue products called Diaxol which will clean SCR systems and prolong the life of exhausts and reduce exhaust clogging as a result of crystallisation deposits. This will in time improve the performance of vehicles and make them less likely to break down.

Diaxol could be a revolution in the bus and coach industry due to the prolonged amount of time which these vehicles spend sat in traffic in urban areas. Total’s estimations show that these vehicles can experience exhaust clogging issues up to 40% of the time which affects fuel efficiency and exhaust performance.
