SYSTEM AND METHOD FOR EMISSIONS DETERMINATION

A method for determining particulate emissions (PE) at an outlet of a gasoline engine (16) is proposed. The method comprises determining a logarithmic particulate emission value (LPE) at the engine outlet by means of a dynamic machine-learning-based model (110), using parameters (RS,AMF,AFR) associated with an engine operating state as an input; and applying an exponential function to the determined logarithmic particulate emission value (LPE) to yield the particulate emissions (PE) at the engine outlet (16).An engine control unit configured to implement such method is also proposed, as well as a system for determining particulate emissions (PE) at an outlet of a gasoline engine, the system comprising processing means configured to implement the above method.
