METHOD AND APPARATUS FOR DETECTING SELECTIVE CATALYTIC REDUCTION INJECTOR OPENING TIME

METHOD AND APPARATUS FOR DETECTING SELECTIVE CATALYTIC REDUCTION INJECTOR OPENING TIME

A method for detecting an opening time of a valve, includes receiving a valve current profile (110, 120, 302) of the valve and processing the valve current profile (110, 120, 302) using at least a slope reflection detector to determine a status of the valve based on an output of the slope reflection...
