ABSTRACT:
A particulate filter trap regeneration system and control mechanism is disclosed including a downstream vent tube section across which a pressure signal is derived as an analog of the exhaust gas stream velocity flowing through the particulate trap. A novel particulate loading parameter formula is disclosed by which the maximum acceptable pressure drop across a loaded particulate trap may be calculated and related to exhaust gas flow through the trap in order to determine when particulate trap regeneration should commence. In one embodiment, a vent tube equipped with a venturi throat for increasing the accuracy of the pressure signal indicative of exhaust gas stream velocity is disclosed along with representative dimensional parameters.
