*catalytic converter: a converter that uses a platinum-iridium catalyst to oxidize pollutants and carbon monoxide into carbon dioxide and water; an anti-pollution device on an automotive exhaust sytem

More and more companies having some connections with automobiles are looking toward more environment-friendly vehicles where emissions are dramatically reduced. The people who are in charge of researching at Daimler AG are delving into the matter of continuous improvement of combustion, exhaust gas aftertreatment, and fuel injection. This research’s aims will be done with a high-level simulation technology.

One of the aims is to help in lessening fuel consumption even more. Simultaneously, the reduction of fuel consumption will take effect while meeting the terms of the rigorous emission cutoff point. This limit continues to increase. Simulations have already been undergoing for a couple of years now. The design of the exhaust gas units and the optimization of the said units had been going through said simulations. The correlation between the simulation and the measurement is what made BLUETEC possible. Not just BLUETEC but the modern exhaust gas aftertreatment is also made possible by the connection between the simulation and measurement.

Engine optimization measures entails cutting down oxide levels. The intelligent exhaust gas aftertreatment system which would operate with no added service fluids and which would trim down additional emissions would help develop the concept of more environment-friendly vehicles. The plan would be that, as a standard, filters and catalytic converters would come together. To be taken note of is how each component would interrelate with each other. For instance, the engine will be notified by the exhaust system when the particulate filter is already filled. When this takes place, the engine ought to respond appropriately.

“Daimler AG’s researchers take these complicated interactions into ac-count in their simulations. They are on the one hand developing models for individual components such as the three-way catalytic converter, oxidation, SCR and NOx storage catalytic converters, and the particulate filter. These models are founded on physical and chemical processes.”

The research and developments for engine optimization continues, which will be a great contribution in helping keeping the environment safe and protected.
