媒保護装置。 A glow plug that is installed near the combustion chamber of an engine to promote ignition of fuel, a detection means that detects an abnormality in the glow plug, a catalyst that passes exhaust gas to purify it, and a passage to the catalyst. a first opening and closing means that opens and closes; a bypass pipe that is arranged in parallel with the catalyst and discharges the exhaust gas to the outside without passing through the catalyst; and a second opening and closing means that opens and closes a passage to the bypass pipe; When the detection means detects an abnormality in the glow plug, the first opening/closing means is actuated to close the passage to the catalyst, and the second opening/closing means is operated.
A catalyst protection device characterized by comprising a controller that operates an opening/closing means to open a passage to a bypass pipe.
