摘要： A diagnostic module for diagnosing a particulate matter sensor in a vehicle includes a sensor mode selection module, a heater power detector, and a protection tube diagnostic module. The sensor mode selection module selects a regeneration mode for the particulate matter sensor from among a plurality of operation modes. The regeneration mode regenerates the particulate matter sensor. The heater power detector determines a voltage output based on a voltage applied to the particulate matter sensor. The voltage output corresponds to operation of the particulate matter sensor in the selected mode. The protection tube diagnostic module performs a diagnostic of the particulate matter sensor. The protection tube diagnostic module selectively diagnoses a fault in the particulate matter sensor based on the voltage output determined during the regeneration mode and a regeneration power threshold.

摘要： An exhaust gas treatment system includes a particulate filter to collect particulate matter from exhaust gas flowing therethrough. The particulate filter realizes a pressure thereacross in response to the exhaust gas flow. A delta pressure sensor determines a first pressure upstream from the particulate filter and a second pressure downstream from the particulate filter. A delta pressure module is in electrical communication with the delta pressure sensor. The delta pressure module determines a pressure differential value based on a difference between the first pressure and the second pressure and generates a diagnostic signal based on a plurality of the pressure differential values and a predetermined time period.

摘要： An exhaust manifold for a vehicle engine may include a plurality of pipes, a pod, a splined collector and a downpipe. Each pipe in the plurality of pipes are operatively configured to be coupled to a corresponding engine chamber at a proximate portion. The pod is operatively configured to align a flow of exhaust gas emerging from each of the corresponding engine chambers to the associated pipe in the plurality of pipes. The splined collector receives the outlet ends of the pipes at a splined collector inlet. The downpipe may be affixed to the splined collector at a small diameter outlet portion. The downpipe includes a first oxygen sensor operatively configured to communicate with a second oxygen sensor disposed in a downstream catalytic converter and an ECM in order to regulate air and fuel for the vehicle engine.

摘要： Provided herein are gas sensor heat shields comprising at least one wall having a top edge and a bottom edge, the wall forming a body, a base connected proximate the wall bottom edge defining a bottom diameter, the base including an aperture capable of receiving a gas sensor, and a circumferential lip proximate the wall top edge extending radially outward and defining an outer lip diameter, wherein the at least one wall is tapered radially outward at an angle of about 3 degrees to about 17 degrees, and the ratio of the outer lip diameter to bottom diameter is at least about 5:3.5. Heat shields can be used to protect gas sensors from heat, specifically those used for exhaust gas systems servicing internal combustion engines and turbochargers.

摘要： An exhaust treatment system includes a particulate filter having a filter substrate configured to trap soot contained in exhaust gas. A regeneration system is configured to perform a regeneration operation that regenerates the particulate filter by burning away soot stored in the filter substrate. A control module is in electrical communication with the regeneration system to generate a first control signal that initiates the regeneration operation based on a comparison between at least one operating condition of the exhaust treatment system and a threshold value. The control module generates a second control signal in response to detecting at least one diagnostic signal. The second control signal initiates the regeneration operation independently of the comparison.

摘要： A method for particulate filter performance monitoring in an exhaust gas treatment system is provided. The method includes monitoring a current received from a soot sensor in the exhaust gas treatment system and comparing the current to a soot sensor current threshold. Based on determining that the current is greater than or equal to the soot sensor current threshold, an accumulated engine out soot value is compared to an accumulated engine out soot threshold. A particulate filter fault is set based on determining that the accumulated engine out soot value is less than the accumulated engine out soot threshold. A monitoring system and an exhaust gas treatment system of an engine are also provided.
