In an exhaust gas after-treatment apparatus () including a particulate filter () that receives an exhaust gas having passes through a catalyst converter () and traps particulates in an exhaust, injectors (through) used for a post fuel injection to activate the catalyst converter (), and a filter control unit () that performs post fuel injection control, the filter control unit () includes a determination portion that determines whether a post fuel injection operation should be started, and a calculation portion that calculates an integration value of a fuel injection amount after the post fuel injection operation is started in a case where the post fuel injection operation is started in responding to the determination portion. The post fuel injection operation is stopped when the integration value has reached a specified value. It is thus possible to appropriately perform the post fuel injection control to activate the catalyst converter.

Exhaust gas after-treatment apparatus

The present invention provides a sheet feeding apparatus having a sheet supporting tray removably mountable within the sheet feeding apparatus and adapted to stack and support sheets, a regulating device provided on the sheet supporting tray and adapted to regulate and position lateral edges of the sheets stacked in the sheet supporting tray, an urging mechanism for urging with a predetermined urging force the sheets stacked in the sheet supporting tray against the regulating device, and an urging force adjusting mechanism for adjusting the urging mechanism so that the urging mechanism can urge the sheets against the regulating device with greater force during insertion of the sheet supporting tray into the sheet feeding apparatus.
