Mobility contributes substantially to personal quality of life as well as to economic development, but has also a negative impact on the local and global environment.

Our vision of a future mobility is based on efficient and emission-free power trains for motor vehicles, powered by CO2-neutral domestic fuels.

The focus of our research activities in cooperation with academic and industrial partners is:

Low-emitting and energy efficient power trains

Dynamic combustion research on natural gas, gasoline and diesel engines for passenger cars, light and heavy duty vehicles.

Engine optimization regarding consumption and emissions:

• Emissions application of engine control systems, development and prototyping of new functions
• Hybridization, energy management

Exhaust gas after treatment

• Development of lambda control and catalytic converter concepts
• Investigation of the aging behavior of catalytic converters in field operation (emission monitoring und surface phenomena on the catalytic converter)
• Investigation of different catalyst supports

Emissions modeling

• Instantaneous 10 Hz emission measurements including the compensation of transport dynamics
• Combined linear dynamic and non-linear 4D modeling of the emission behavior of motor vehicles and non-linear, dynamic modeling of catalytic converters
• Determination of the relative oxygen level (ROL) and of the oxygen storage capacity (OSC) in the catalytic converter based on instantaneous emission measurements

Particulates and soot formation

• Formation of volatile particles in the exhaust of motor vehicles
• In-cylinder based soot formation and oxidation in diesel engines
• Formation of particles in big diesel engines
• Physical and chemical particulate characterization
