Übersetzung für "Selective catalytic reduction system" in Deutsch

If tampering of the Selective Catalytic Reduction (SCR) system is identified by direct monitoring of nitrogen oxides (NOx) emissions, the conditions under which its driver inducement system is activated should be better defined.

To bring about constant reduction of NOx-emissions in the SCR (Selective Catalytic Reduction) system, AdBlue®, a solution of 32.5% urea in water, will be injected into the exhaust gas flow in front of the SCR catalysts.

In the reducing agent metering system for injection of a reducing agent into the exhaust gas flow of a supercharged internal combustion engine for selective catalytic reduction, the metering system being connectable to a reducing agent tank from which the reducing agent can be taken, the metering system having at least one nozzle by which the reducing agent can be injected by means of compressed air into the exhaust gas flow, at least one part of the compressed air being taken from a charger of the internal combustion engine, it is especially advantageous that the compressed air supply has an electric air pump for producing compressed air and parallel to the air pump has a bypass so that the charging air of the charger overflows/can overflow the air pump via the bypass.

The invention relates to a reducing agent metering system for injecting a reducing agent into the exhaust gas flow of a supercharged internal combustion engine for selective catalytic reduction, the metering system being connectable to a reducing agent tank from which reducing agent can be taken, the metering system having at least one nozzle by which the reducing agent can be injected into the exhaust gas flow by means of compressed air, at least one part of the compressed air being taken from a charger of the internal combustion engine.

Since the purification of nitrogen oxides with the addition of a reducing agent is also known as selective catalytic reduction, the system is also referred to as SCR (selective catalytic reduction) system.

In some cases the newest exhaust gas limit values will only be achieved with an SCR (Selective Catalytic Reduction) system for selective catalytic reduction of nitrogen oxides in exhaust gases of internal combustion engines, which operates with a urea solution, which must also be carried on the vehicle.

System (300) according to any of claims 17 or 18, wherein the system is used in combination with a diesel engine, in particular in a Selective Catalytic Reduction (SCR) system of a diesel engine.

In some cases the newest exhaust gas limit values will only be achieved with an SCR (Selective Catalytic Reduction) system for selective catalytic reduction of nitrogen oxides in exhaust gas of internal combustion engines, which operates with a urea solution, which must also be carried on the vehicle.

The SCR (Selective Catalytic Reduction) system installed downstream now plays its part in reducing the level of nitrogen oxides (NOx).

When required by local or national regulations, a SelasTM reformer furnace can be equipped with Low NOx burners or a Selective Catalytic Reduction (SCR) system to reduce NOx emissions to very low levels.

This modular SCRT® (Selective Catalytic Reduction Technology) system is capable of removing not only almost all gaseous pollutants, but also nitrogen oxides from diesel exhaust gases.

When required by local or national regulations, a Selas™ reformer furnace can be equipped with Low NOx burners or a Selective Catalytic Reduction (SCR) system to reduce NOx emissions to very low levels.

Depending on the series, externally cooled exhaust-gas recirculation or an SCR (selective catalytic reduction) system is used to reduce NOx and particulate emission.

Today, diesel engines whose exhaust gases are treated by the SCR (Selective Catalytic Reduction) system are used to comply with the Euro 4 und Euro 5 emission standards.

So-called Selective Catalytic Reduction systems (SRC catalysts) might become a solution for this problem.

In Europe, the market is currently dominated by high-grade, chemically based SCR (selective catalytic reduction) systems, while in the USA soot-particulate filter systems predominate.

The company is a leading global supplier of plastic fuel systems solutions, selective catalytic reduction systems (SCR), camshafts and camera and sensor cleaning solutions.

Aqueous urea solution is used, for example, in SCR systems (selective catalytic reduction systems), in order, in a catalytic process, to reduce the proportion of the nitrogen oxide in the exhaust gas from diesel engines.
