EXHAUST GAS AFTERTREATMENT SYSTEMS FOR DIESEL ENGINES WITH RESPECT TO FUTURE EMISSION LEGISLATION

The severe future emission limits require extraordinary development work with respect to both reducing engine-out emissions by improved combustion processes and tail pipe emissions by new exhaust gas aftertreatment systems (EGAS). Today, the main EGAS work for engine application as well as research and development concentrates on oxidation catalysts, particulate traps, and nowadays DENOX catalysts. The paper deals with a) the development status of different EGAS and typical emission reduction examples for various engine and vehicle applications, and b) the interaction between combustion development and the kind of EGAS used. This is because the efficiency of each type of EGAS is related to exhaust gas breakdown and consequently to the combustion process development. Based on current development work and test results obtained, the most probable EGAS solutions to meet future European and US emission legislation levels will be summarized.
