摘要： A real time, average pressure difference method for monitoring doser efficiency is described that determines the difference between the average pressure when the doser is not injecting and the average pressure when the doser is injecting at a predetermined commanded injection rate. The average pressure difference method results in improved doser efficiency monitoring. The method can be implemented in a number of areas. For example, in a diesel truck application, the doser efficiency can be monitored accurately in real time.
