Exhaust gas aftertreatment
With ever more stringent NOx and Particulate Matter (PM) emission standards in place and further reductions in emission levels still to come, the integration of exhaust gas aftermarket systems into engine development and calibration offers new degrees of freedom regarding total system performance and costs.
Our Approach
Having profound experience in the application and calibration of both engines and various degrees of exhaust gas aftertreatment systems ranging from 'simple' DOC and DPF to 'full scale' DOC+DPF+LNT/SCR, MAHLE's approach always focuses on optimal combination of internal combustion and aftertreatment measures. Given the complex interactions between the systems and the time-to-market pressures. MAHLE's excellent testing data quality along with advanced DoE (design of experiments) techniques and smart data analysis tools allow for better solutions in less time.
