理装置。Exhaust particulate after-treatment comprising, in the exhaust passage of an internal combustion engine, a trap that captures particulates in the exhaust, an exhaust heating burner that heats the exhaust upstream of the trap and regenerates the trap, and an ignition device for the exhaust heating burner. In the apparatus, a cooling air passage is provided in the outer layer of the heat generating part of the ignition device, and after the ignition device is activated and ignition is completed, the ignition device is heated through an on-off valve that opens after energization of the ignition device is stopped while the exhaust heating burner is in operation. An exhaust particulate aftertreatment device characterized in that air is supplied to a cooling air passage.
