IAV developed an combination of a MAP-based raw emission model, which is input to a Neural Network. Focus is on raw emissions from ICE vehicle (NOx, CO, HC, PM.....) The MAP is calibrated with stationary measurements from a engine test bench with high robustness through DoE methods and a wide range of input variation (tolerances and calibration ran...
The upcoming EU7 emission standards will likely impose new regulations on passenger and commercial vehicles that could be very challenging for on-board emission monitoring (OBM). Key point with OBM is emission compliance under all relevant driving conditions. Limited availability of sensor technologies will require to model the emissions from engin...
Raw-Emission Modelling for EU7. Machine Learning Approach for OBM and OBD to model ICE emissions.
Conventional methods of physicochemical models require various experts and a high measurement demand to achieve the required model accuracy. With an additional request for faster development time for diagnostic algorithms, this method has reached the limits of economic feasibility. Machine learning algorithms are getting more popular in order to ac...
On-Board Monitoring for EU7 will need a Holistic Approach to use the sensors and models in Exhaust Gas Treatment for giving the best values for the different gaseous species. Ageing and tolerances of the components have to be addressed for OBM and used for OBD and Controls as well. The approach is the same for diesel and gasoline engines.
RF Antenna for SCR, TWC, GPF - Machine Learning for Load Measurement. Developed by University of Bayreuth (Prof. Moos) and Continental/Vitesco. Between 2014 and 2019 investigation of this sensor by IAV on different SCR systems. Very promising results.
Simulation-based Generation of Specifications for a new Sensor Concept in Diesel Exhaust Treatment Applications
A schematic diagram of a diesel engine with exhaust gas aftertreatment (DOC, DPF and SCR) is shown in ➊. During the test drive, gas composition measurement readings are recorded at sampling points downstream of the DPF. As the relevant sensors are not available in the vehicle, this is only possible with appropriate measuring equipment — for example...
