摘要： An exhaust gas treatment system for an internal combustion engine has a reluctant delivery system that delivers reductant to an exhaust stream in an exhaust aftertreatment system. A temperature sensor is positioned in or near the flow of reductant and exhaust to measure the temperature of the reluctant and exhaust. A change in temperature over time, such as an increase, decrease, or change in variation amplitude, indicates the presence of a reductant deposit in the system. Detection of the deposit initiates a regeneration cycle in which the operating characteristic of the system change to eliminate the reductant deposit to present it front hindering the performance of the exhaust aftertreatment system.

摘要： An internal combustion engine system (10) comprising a reductant delivery system (30) in reductant supplying communication with combustion exhaust, the reductant delivery system (30) comprisinga reductant tank (32) containing reductant, a doser (36) that supplies reductant to the combustion exhaust, a reductant pump (34) that draws reductant from the reductant tank (32) and delivers the reductant to the doser (36), a filter module (100) positioned within the reductant tank (32) to filter the reductant, the filter module (100) comprising a venting port (210) positioned to release entrained gas from the filter module (100) to restrict entry of entrained gas into the reductant pump (34) and a venting line (102). The filter module (100) is positioned adjacent to a bottom wall of the reductant tank (32) and the venting line (102) extends substantially vertically to convey the gas from the venting port (210) through the reductant in the reductant tank (32) to a gas reservoir above the reductant within the reductant tank (32).

摘要： An exhaust gas treatment system for an internal combustion engine may have a reductant delivery system with a reductant tank (32). A filter module (100) positioned in the reductant tank filters reductant before it is conveyed to the reductant pump (34) to remove impurities. In order to reduce gas flow to the pump (34), the filter module (100) may have an outlet port leading to the reductant pump (34) and a venting port (210) positioned above the outlet port (212) such that gas bubbles float to the venting port (210) prior to entry of the reductant into the outlet port (210). The filter module (100) may be secured to a tank level tank level sensor assembly (80), and may vent the gas to a gas reservoir (72) above the reductant in the reductant tank (32). Such a filtration system may operate independently of any return line that conveys reductant back to the reductant tank (32).
