内燃機関の排気微粒子処理装置。 A trap installed in an exhaust passage of an engine to collect particulates in the exhaust gas, a burner for heating and burning the exhaust particulates collected in the trap, a regeneration timing determination means for determining the regeneration time of the trap, and a trap. a burner operating device that operates the burner for combustion when it is determined that it is time to regenerate the burner; a burner operating state detection means that detects the combustion operating state of the burner; and whether or not the burner is ignited based on the detected combustion operating state. ignition determination means for determining the presence or absence of a stable combustion state of the burner based on the detected combustion operation state; and combustion state determination means for determining the presence or absence of a misfire of the burner based on the detected combustion operation state. A burner operation stop means for stopping the operation of the burner operating device so as to stop the operation of the burner when any one of the above-mentioned non-ignition, unstable combustion, and misfire is determined. An exhaust particulate treatment device for an internal combustion engine, characterized in that:
