Abstract
An exhaust gas sensor system includes an inner chamber disposed around a sensor element. The inner chamber has either a cylindrical shape or a frusto-conical shape. The system further includes an outer chamber disposed substantially around the inner chamber to redirect a flow of an exhaust gas stream having an original direction by allowing the exhaust gas stream to strike a surface of the inner chamber to change the original direction of the flow to a substantially perpendicular direction relative to the original direction, then to substantially reverse the substantially perpendicular direction of the flow to create a substantially reversed flow within the inner chamber. Alternately the exhaust sensor system includes a sintered metal filter that prevents exhaust gas particles from fouling a sensor element. The system further includes an electric source coupled to the sintered metal filter to heat the sintered metal filter to a temperature sufficient to remove the exhaust gas particles from the sintered metal filter.
