The Topsoe approach to automotive research combines research from fundamental studies, lab-scale testing, engine testing and on-road evaluation, validation and production support.

Fundamental research

Topsoe's vast expertise in characterisation and testing form the basis of the clarification of the mechanisms and kinetics of the SCR reaction. Catalysed soot combustion is studied through electron microscopy allowing the calculation of the reaction pathway and activation energies. This enables the development of catalytic coatings which assist the soot combustion.

Catalyst discovery and development

The optimal use of base and noble metals in automotive catalysts is of vital importance to be able to provide the automotive market with the most cost effective solutions.

Innovative substrates

Topsoe has developed its own corrugated substrates for use in automotive catalysts. The Topsoe substrate and its production process offer unique features such as flexible substrate diameter, low weight and low sulphatisation.

Urea injection algorithms for SCR

Thorough steady state and transient testing together with simulation expertise has led to the development of advanced urea injection algorithms for SCR systems based on real-time kinetic calculations. The algorithms can be executed fast enough to be included in standard electronics used for engine management. With the use of the Topsoe injection algorithms a high NOx conversion can be achieved while the ammonia slip is kept at low levels. The use of the algorithms does not require any time consuming mapping of the engine.

Novel concepts for meeting future legislations

Topsoe is continuously evaluating various aftertreatment system concepts in order to be able to provide the optimal solution to the automotive market. Innovative thinking allows for system concepts with overall low precious metal loadings that still can achieve excellent performance for both NOx and PM reduction. Also aftertreatment systems concepts are tailored for advanced engine concepts such as HCCI (Homogeneous Charge Compression Ignition).
