Abstract
A method for controlling emissions in an engine system including an internal combustion engine and a catalytic converter with oxygen storage capacity. The method includes determining a real time oxygen storage level of the three-way catalytic converter based on a real time exhaust gas flow rate and a real time measured upstream oxygen quantity with respect to the catalytic converter. Further, maintaining an optimal oxygen storage level of the three-way catalytic converter for different types of fuel used in the internal combustion engine.
