Abstract: This burner is disposed at the upstream side of a DPF and raises the temperature of exhaust by combusting an air-fuel mixture of air and fuel in a combustion region within a flame holder. The burner is provided with: an upstream-side cover enclosing the peripheral wall of the flame holder; and a partition wall that partitions the gap between the flame holder and the upstream-side cover into a prior-stage exhaust chamber and a latter-state exhaust chamber. An exhaust tube through which exhaust from an engine flows is connected to the upstream-side cover; a through hole that interconnects the prior-stage exhaust chamber and the latter-stage exhaust chamber is formed at the partition wall; exhaust flows in from the exhaust tube at the prior-stage exhaust chamber; and exhaust flows in from the prior-stage exhaust chamber through the through hole to the latter-stage exhaust chamber.

Abstract: A burner for an exhaust purifying device includes a tube, an air supply port for supplying air for combustion into the tube, a fuel supply port for supplying fuel into the tube, and an ignition portion. The tube includes a premixing chamber for mixing air for combustion and fuel to generate a pre-mixed air-fuel mixture, a combustion chamber for combusting the pre-mixed air-fuel mixture to generate post-combustion gas, and a discharge port for discharging the post-combustion gas. The ignition portion ignites the pre-mixed air-fuel mixture in the combustion chamber. The tube further includes a swirling flow generation unit arranged upstream of the premixing chamber for generating a swirling flow of which the center direction corresponds to a fuel injection direction and a diffusion unit arranged downstream of the swirling flow generation unit in the premixing chamber for diffusing the fuel incorporated in the swirling flow.

Abstract: An engine exhaust purification device includes a filter, a burner, and a control unit. The filter is arranged in an engine exhaust pipe. The burner burns fuel injected from a fuel injection nozzle and heats exhaust to increase the temperature of the filter at an upstream side of the filter in the exhaust pipe. A period including a single fuel injection period and a single injection stop period is set as a single injection cycle. The fuel injection period is a period injecting fuel a number of times at a predetermined frequency. The injection stop period is a variable period that stops fuel injection. The control unit controls the fuel injection nozzle so that the fuel injection nozzle injects the fuel according to the injection cycle. The control unit is configured to lengthen the injection stop period as the temperature of the filter increases.

Abstract: Injection nozzle 7 and electrode rods 8 and 9 (ignitor) are surrounded by double-cylinder flame stabilizer 10. Toroidal blocking plate 13 closes between inner and outer cylinders 11 and 12 of the stabilizer at its distal end whose proximal end is connected with line 15 for introducing combustion air 14 to between the cylinders. Inflow holes 16 are formed throughout the inner cylinder at its proximal end. Peripheral fins 17 are formed peripherally on the inner cylinder radially inwardly through cutting and bending-up at positions shifted from the inflow holes toward the distal end of the inner cylinder such that combustion air is introduced from circumferentially to form swirling flow inside the inner cylinder. End fins 18 are formed on the blocking plate in fuel injection direction through cutting and bending-up such that combustion air is discharged circumferentially to form swirling flow around flame 21.
