Method for determination of oxygen storage capacity of oxidation catalyst involves reaching maximum oxygen loading of oxidation catalytic converter after driving internal combustion engine over certain length of time

摘要

The method involves determination of oxygen storage capacity (OSC) of oxidation catalyst with gradient (delta S/delta t) of signal values (S) of oxygen loading sensor. Maximum oxygen loading (OSmax) of oxidation catalytic converter is reached after driving the internal combustion engine over certain length of time and corresponding upper limit value (SG) of signal values of oxygen loading sensor is obtained.
