· Engine Off for 4 hours. 4. Ignition On, engine Off. 5. Measure and record the scan tool Exhaust Gas Temperature Sensor 1 and 2 values. 6. Engine running, verify the scan tool StartUp Particulate Matter Sensor Temperature is within 50°C (90°F) of the previously recorded scan tool Exhaust Gas Temperature Sensor 1 and 2 values.
The ability to quantify particle mass and number concentrations in the exhaust stream of combustion engines during inuse operation is of critical importance for continuously monitoring and diagnosing the particulate matter removal efficiency of modern exhaust gas aftertreatment systems. Extensive literature survey suggested a sensor operating on the diffusioncharging …
· Exhaust Particle Sensor for OBD Application 2011010626 Efforts to develop a sensor for onboard diagnostics (OBD) of diesel vehicles are intensive as diesel particulate filters (DPFs) have become widespread around the world. This study presents a novel sensor that has been successfully tested for OBD diagnosis of damaged DPFs.
Soot sensors have been developed for two main types of applications: Estimation of the amount (mass) of the soot accumulated in a diesel particulate filter, in order to utilize accurate DPF regeneration strategies. DPF failure detection which may result in excess PM emissions, to trigger an OBD fault signal.
Based on wellproven multilayer technology Bosch has developed a ceramic exhaustgas sensor for particulate matter (EGSPM) which is shown in figures 24. On the sensing surface a DC voltage is applied to two interdigital electrodes (IDE), on which soot particles are deposited from the exhaust gas during operation.

grounded sensor’s body, a small quantity is lost with the charged particles exiting the sensor. This “escaping current” is a measurement of the particle concentration in the exhaust gas.
· Structure and principle of the new leakage current particulate matter (PM) sensor are introduced and further study is performed on the PM sensor with the combination of numerical simulation and bench test. High voltage electrode, conductive shell, and heaters are all builtin. Based on the principle of Venturi tube and maze structure design, this sensor can …
Because the stricter emission regulations of diesel engine particulate matter are continuously presented, the new type sensors for diesel onboard diagnostics (OBD) are needed to detect PM emissions accurately. Sufficient heat resistance and endurance, ability to endure the harsh environment of the exhaust are necessary for these sensors. The working principles of …
