Claims (1)

[Scope of utility model registration request] a trap installed in the exhaust passage of an engine to collect particulates in the exhaust; a heating combustion means for heating and burning the exhaust particulates collected in the trap; and a trap for detecting the state of collection of the exhaust particulates in the trap. In an exhaust particulate processing device for an internal combustion engine, comprising a state detection means and a control means for operating the heating combustion means based on a detection signal from the collection state detection means, an alarm means for issuing an alarm; A timing means that starts timing when the means was last activated and measures the operating time of the engine from the previous activation to the current activation, and a target engine operating time from the previous activation to the current activation is set. a setting means;
An abnormality alarm device for an exhaust particulate processing device for an internal combustion engine, characterized in that it is provided with a determining means for issuing an activation signal to the alarm means when the operating time measured by the timer deviates from the target operating time. .
