What is a particulate matter sensor?
The Particulate Matter (PM) sensor is an exhaust sensor which measures cumulative particulate mass used for on-board diagnostics (OBD) and helps detect leakage in the diesel particulate filter (DPF). The integrated heater maximizes sensor regeneration across a wide range of operating conditions.
How does particulate matter sensor work?
The PM sensor uses the principle of laser scattering to count the particles in the air. A fan draws air into the cavity with fine dust particles suspended in the air. As the laser beam shines through the air, the dust particles deflect or scatter some of the laser light.
Is a particulate matter sensor a NOX sensor?
The NOX sensor supports control of the required urea dosing in SCR systems for NOX reduction and monitor- ing (OBD) of the SCR components. The sensor is available for passenger car and commercial vehicle applications. Particulate matter sensor. The particulate matter sensor enables diagnosis of the particulate filter.
What is a PM2 5 detector?
WITNESS real-time, reliable measurement of PM2. 5 dust concentrations! (PM2. 5 refers to particles that are 2.5 microns or smaller in diameter.) This sensor uses laser scattering to radiate suspending particles in the air, then collects scattering light to obtain the curve of scattering light change with time.
What are 4 different sources of particulate matter?
Natural sources of PM include sea salt, dust (airborne soil, also called crustal material), secondary sulphate, pollen, black carbon from wild fires, and volcanic ash.
What are examples of particulate matter?
Particulate matter is the sum of all solid and liquid particles suspended in air many of which are hazardous. This complex mixture includes both organic and inorganic particles, such as dust, pollen, soot, smoke, and liquid droplets.
How do you collect particulate matter?
The most common instruments for measuring particulate matter measure either its concentration or size distribution. The most accurate measurements are obtained from instruments that use a gravimetric (weighing) method. Air is drawn through a preweighed filter, and particles collect in the filter.
Can I clean a DPF myself?
Don’t DPFs clean themselves? In theory, yes. “Passive Regeneration” or if appropriate Active DPF regeneration will take place as part of a healthy diesel engine running cycle, but active regeneration can fail once a blockage reaches a certain level. Sometimes a “forced” regeneration may be carried out by a mechanic.
How do you manually regenerate a DPF?
To kick off a manual DPF regeneration you should
- Put the vehicle in neutral.
- Put on the hand brake.
- Leave the pedals alone!
- Press and hold the DPF button for 2 seconds or longer.
Can you clean a DPF sensor?
Can you clean a DPF? (Diesel Particulate Filter) – Yes, you can. DPF cleaning is one of the most commonly-requested services now amongst our 500+ TerraClean dealers. Many of our dealers actually provide this service to neighbouring garages who need to have their customers’ vehicles’ DPFs cleaned.
Which is the best sensor for particulate matter monitoring?
NextPM sensor series have been designed to comply with the highest quality standards for particulate matter monitoring. With 3 patents to provide the best quality / size / price compromise NextPM gives you real time PM1, PM2.5 and PM10 in numbers or mass.
How does a particulate matter sensor work on a Bosch car?
Particulate Matter (PM) Sensors monitor the function of the Diesel Particulate Filter (DPF) to detect excessive PM emissions. Where to buy You can buy Bosch Auto Parts at a number of online retailers and retail stores near you. When should a particulate matter sensor be changed?
How long does sps30 particulate matter sensor last?
The SPS30 particulate matter (PM) sensor enables accurate measurements from the device’s first operation and throughout its lifetime of more than eight years. Here you find the nearest distributor and/or representative in your area.
