A control module comprises a PM filter temperature determination module that determines the temperature of a PM filter in communication with an exhaust gas from an engine; and a reduced engine power module in communication with the PM filter temperature determination module that reduces the power ...
A regeneration system includes a particulate matter (PM) filter. The PM filter has an upstream end that receives an exhaust gas from an engine. An air pump circuit directs ambient air to a first exhaust conduit upstream from the PM filter. A control module determines a current soot loading ...

In consequence, there is still much to be learned about the sources of particulate matter that may control the oxidative potential concentration7. Here we use field observations and air-quality modelling to quantify the major primary and secondary sources of particulate matter and of oxidative ...
there is still much to be learned about the sources of particulate matter that may control the oxidative potential concentration7. Here we use field observations and air-quality modelling to quantify the major primary and secondary sources of particulate matter and of oxidative potential in Europe. ...
A control module supplies fuel using the injector to burn particulate matter in the particulate filter when the control module determines that regeneration is needed. The control module selectively supplies fuel to exercise the injector during periods when the control module determines that regeneration ...
The profiles are compatible with the inputs of current photochemical air quality models, including the Community Multiscale Air Quality Aerosol Module Version 6 (AE6). The composition of light-duty gasoline PM2.5 emissions differs significantly between cold start and hot stabilized running emissions, ...
The TAP first improved the wind-blown dust module and then trained the model to correct the simulated PM2.5 components ratios based on the ground-based measurements and extreme gradient boosting algorithm. Finally, the PM2.5 constituent concentrations were calculated based on the PM2.5 species ...
the storage module uses CH376S, the wireless data-transmission module uses a wireless XBeePRO900HPS3B250MW component, the control and display module has a 2.4 inch color touch screen that is mainly used to display measurement data and the function and remote-control status of the onborne PM...
Active regeneration happens when changes in engine operation are required to get the Engine Control Module (ECM) to burn out and/or some catalyst is introduced. This is common among trucks with a lighter duty cycle, because soot accumulates while idling or going slowly through traffic. ...
