For several years, the Euro IV, V, VI onwards Standard Emissions Regulations significantly restricted marginal values of exhaust gasses, specifically nitric oxide, from commercial vehicles. Recently, these restrictions included private vehicles. In order to reach these objectives, most European OEMs rely on the well-established Selective Catalytic Reduction (SCR) technology. AdBlue can help reduce nitric oxide emissions.
How does AdBlue work?
AdBlue is a high purity, 32.5% urea solution directly injected into the exhaust gas where it serves as reducing agent. The released ammonia subsequently reacts with the nitric oxides on the catalyst to form elementary nitrogen and water; both are natural constituents of the air we breathe. Hence, the amount of nitric oxides in the emission can be reduced.
Reduced fuel consumption and constant engine output
The combination of SCR Catalysts with AdBlue needs higher temperatures in the motor to elevate the exhaust gas temperature for the effective AdBlue NOX reduction. This leads to higher fuel efficiency and less unburned fuels and less sooty particles in the exhaust gases without affecting engine output.
