Within the past few years, the Environmental Protection Agency EPA has introduced strict emissions standards in order to reduce harmful pollutants from being released into the environment. It contains the diesel oxidation catalysts DOC , diesel particulate filters DPF , and selective catalytic reduction device SCR to ensure the air coming out of the engine is cleaner than the air going in. When exhaust exits the engine it is made up of carbon monoxide, hydrocarbons, and particulate matter. These are all harmful to the environment and must be captured in the 1-box before exiting through the exhaust outlet. The first defense after the exhaust leaves the engine is the diesel oxidation catalyst. The DOC is designed to convert the carbon monoxide and hydrocarbons into carbon dioxide and water. The DEF reacts with the nitrogen oxides in the SCR to form nitrogen and water which are both already present in the atmosphere and safe to breathe. After passing through the DOC the exhaust moves on to the diesel particulate filter.

An accurate estimate of a DPF soot mass allows devising a proper regeneration strategy how often, when to start or stop a regeneration , while inaccurate estimates result in unsuitable regeneration timing. This article focuses on soot sensors used in engine emission control systems—installed permanently on-board of a vehicle or otherwise in the exhaust system of an internal combustion engine. Compared to laboratory equipment, on-board sensors are significantly smaller, but also less accurate. Full access requires DieselNet subscription.

Sensors for DPF fault determination include accumulating type sensors using a resistive electrode, as well as electric charge based devices.

Circuit Description The aftertreatment particulate matter sensor is a smart device and communicates with the engine control module ECM via the J data link. The aftertreatment particulate matter sensor performs internal diagnostics and reports malfunctions back to the primary ECM using the J data link. The particulate matter sensor is permanently attached to the particulate matter control module.
