may also be fed into the engine inlet air stream as required by the combustion system designers. The reformate delivery point and quantity can be selected based on the operating conditions and the aftertreatment requirements of the specific engine application by controlling flow control valve20. ...
Cylinder deactivation is used to raise the exhaust gas temperatures and reduce excess exhaust air, richening the air/fuel ratio into the NOx trap. The deactivated cylinders in the present invention may be used as partial oxidation (POx) reactors to provide rich exhaust products to purge the NOx...
