Abstract
A real time doser efficiency monitoring method is described that measures the average instant pressure difference within one duty cycle of the doser injector. The disclosed method results in improved doser efficiency monitoring. The disclosed method can be implemented in a number of areas. For example, in a diesel truck application, the doser efficiency can be monitored accurately, for example within 5% error, all the time, no matter whether the truck is in a transient or steady state.
