摘要： An engine system includes a diesel engine having an exhaust manifold connected to the diesel engine. An exhaust passage is connected to the exhaust manifold and a diesel particulate filter is disposed in the exhaust passage. An air intake passage is provided for supplying fresh air to the diesel engine. A bypass passage is connected between the air intake passage and the exhaust passage in a location downstream of the diesel particulate filter. The bypass passage includes a bypass control valve for opening and closing the bypass passage during a diesel particulate filter regeneration cycle when the vehicle is at low speed or idle.

摘要： A sensor diagnostic system comprises first, second, and third dosing agent sensors and a control module. The first, second, and third dosing agent sensors indicate whether a dosing agent is present at first, second, and third volumetric levels of a dosing agent tank, respectively. The second volumetric level is greater than the first volumetric level and the third volumetric level is greater than the second volumetric level. The control module selectively diagnoses a sensor fault in at least one of the first, second, and third dosing agent sensors based on the indications of the first, second, and third dosing agent sensors.
