e3: How it Works
e3 is a post combustion, after-treatment process that takes place in the exhaust system, never interfering with the performance of the engine itself.
The technology is simple, robust and reliable, consisting of very few parts. Main components include a tank, an injection system and a catalytic chamber.
An onboard diagnostic system monitors the Diesel Exhaust Fluid (DEF)/AdBlue level and indicates when to refill the tank.
DEF/AdBlue is a non-hazardous, high-purity, colorless solution containing 32.5% urea. The rest is deionized water.
Urea is made up of ammonia and carbon dioxide. It's used as an artificial fertilizer and it's found in cosmetics and other products.
Tank holds Diesel Exhaust Fluid (DEF)/AdBlue
The pump and injection system unit reacts to the emissions output of the engine by continuously varying the amount of DEF/AdBlue added to the exhaust stream – effectively maintaining control of emissions released into the environment.
In the catalytic chamber, nitrogen oxides are transformed into harmless nitrogen gas and water vapor.
