Abstract: Methods and systems are provided for adjusting flow of exhaust gas from downstream of an exhaust turbine outlet to an exhaust gas aftertreatment device inlet via a compact turbine outlet cone with adjustable swirl vanes. Exhaust flow reaching the exhaust gas aftertreatment device is adjusted based on a desired exhaust gas temperature and exhaust gas flow rate at the aftertreatment device. During cold start conditions, the swirl vanes may be closed to concentrate exhaust gas flowing towards a portion of the aftertreatment device while after attainment of aftertreatment device light-off temperature, the position of the swirl vanes may be adjusted to introduce turbulence and homogeneity to exhaust flow reaching the exhaust aftertreatment device.

Abstract: A regeneration device (22) executes regeneration treatment of a filter (21) in an exhaust gas purifying device (18) by burning particulate matter trapped in the filter (21). The regeneration device (22) interrupts the regeneration treatment of the filter (21) when an exhaust gas temperature T detected by an exhaust gas temperature sensor (26) becomes less than an exhaust gas temperature threshold Tt during a period of performing the regeneration treatment of the filter (21). In a case where the regeneration treatment of the filter (21) is interrupted, when the exhaust gas temperature T becomes equal to or more than the exhaust gas temperature threshold Tt, the regeneration treatment of the filter (21) is restarted.

Abstract: A diesel particulate defuser (“DPD”) is connected to an exhaust pipe of a diesel engine, an exhaust gas temperature during automatic regeneration of the DPD is detected, and the difference between the detected exhaust gas temperature and a target regeneration temperature is determined.

Further, the system includes detecting the temperature of the exhaust gas during DPD regeneration when the DPD is automatically regenerated, calculating a deviation between the detected temperature of the exhaust gas and a target temperature for the DPD regeneration, and controlling a quantity of the post injection by resetting an integral control term used in a PID control to zero when running mode automatic regeneration is shifted to idling mode automatic regeneration after a vehicle is stopped, when PID-controlling the quantity of the post injection based on the deviation.

Abstract: A diesel particulate filter (“DPF”) system that is more convenient than a conventional DPF system, including a DPF having a catalyzed soot filter (“CSF”) that is connected to an exhaust pipe of a diesel engine in order to collect particulate matter (“PM”) in exhaust gas, and a diesel oxidation catalyst (“DOC”) provided on an upstream side of the CSF; and temperature sensors provided respectively on an upstream side and a downstream side of the DOC. When a PM accumulation amount in the CSF exceeds a fixed amount, DPF regeneration is performed by setting a temperature detected by the upstream side temperature sensor at or above a first threshold and setting a temperature detected by the downstream side temperature sensor at or above a second threshold. When a breakdown is detected in the upstream side temperature sensor, the second threshold is modified upward.
