EXHAUST GAS AFTER-TREATMENT APPARATUS |
摘要 |
<p>In an exhaust gas after-treatment apparatus (30) including a particulate filter (32) that receives an exhaust gas having passed through a catalyst converter (31) and traps particulates in an exhaust, injectors (6 through 9) used for a post fuel injection to activate the catalyst converter (31), and a filter control unit (36) that performs post fuel injection control, the filter control unit (36) 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.</p> |
