  • Patent number: 11795884
    Abstract: A control device is applied to an internal combustion engine equipped with an electric heating catalyst system provided with an EHC. The control device executes a preheating process to warm up an exhaust gas reduction catalyst prior to a start of the internal combustion engine by supplying electric power to the EHC, when the control device determines that a temperature of the exhaust gas reduction catalyst is lower than an activation temperature. The control device executes a determination process for determining whether water is adhered to a catalyst carrier. The control device starts the internal combustion engine without executing the preheating process when the control device determines by the determination process that water is adhered to the catalyst carrier, even when the control device determines that the temperature of the exhaust gas reduction catalyst is lower than the activation temperature.

  • Patent number: 9039981
    Abstract: A laminated body composed of a holding member and an inner cylinder is arranged between a heat generation element, which is electrically energized to generate heat, and a case which covers the heat generation element, and the inner cylinder has an upstream side end portion extended to a more upstream side than an upstream side end face of said heat generation element and an upstream side end face of said holding member to form an extension portion, which is formed with a protruding portion protruding to an inner side in a diametrical direction. A flow of an exhaust gas, which flows backwards after colliding with the heat generation element, will be obstructed by said protruding portion. As a result, the backflow exhaust gas stops flowing into a gap between the case and the inner cylinder.

  • Patent number: 9027332
    Abstract: An exhaust treatment system may include a burner, a flame sensor assembly and a control module. The flame sensor assembly may be at least partially disposed within the burner and may include an insulator and an electric heating element in heat transfer relation with the insulator. The control module may be in communication with the flame sensor assembly. The control module may determine whether a flame is present in a combustion chamber based on feedback from the flame sensor assembly. The control module may detect contamination on the insulator based on feedback from the flame sensor assembly. The control module may operate the heating element in a first mode in response to detection of a contamination in which the control module causes electrical power to be applied to the heating element to raise a temperature of the heating element to burn contamination off of the insulator.
