Abstract

See full text

An internal combustion engine exhaust purification device includes a filter which is disposed in an exhaust path and collects particulate matter in exhaust gas, an injection valve which is disposed upstream of the filter in the exhaust path and injects fuel into the exhaust path, a fuel pump which supplies a fuel to the injection valve, a shut-off valve which is interposed between the fuel pump and the injection valve, and selectively shuts off a fuel supply from the fuel pump to the injection valve, and a control unit which controls the injection valve and the shut-off valve. The control unit closes the shut-off valve when the control unit detects an opened adherence failure of the injection valve and detects an abnormal temperature rise of the filter during regeneration of the filter.
