Abstract
The present invention is a turbocharger () and control system based strategy to control exhaust gas filters () for aftertreatment regeneration. The air handling system () uses the variable turbine geometry (VTG) of the turbine () and a compressor () flow control bleed valve () to drive pressurized intake air into the exhaust. The oxygen rich exhaust gas can then be mixed with fuel and combusted. Increasing the temperature of the exhaust gas will combust the excess exhaust gas emissions and reduce the pressure drop across the filter (). This system () can be used under any operating conditions so as to be available to combust the excess exhaust gas emissions when needed.
