Claims

[Claims for Utility Model Registration] A particulate filter provided in an exhaust pipe to remove particulates from exhaust gas, and a particulate filter provided in a branch of the exhaust pipe between an exhaust manifold and the filter, and a relief valve. an exhaust gas chamber provided with the exhaust gas chamber; a valve that selectively sends exhaust gas only to either the filter or the exhaust gas chamber; a drive device that drives the valve by operating a switch; an exhaust gas pipe that injects fuel in front of the filter with an injection nozzle; an exhaust gas injection valve that opens and closes this exhaust gas pipe; a fuel injection pipe that injects fuel with an injection nozzle in front of the filter; A fuel injection valve that opens and closes, a pressure sensor that detects the pressure in the exhaust pipe in front of the particulate filter, and a signal of the pressure detected by the pressure sensor is input, and when the pressure is equal to or higher than a predetermined value, the exhaust gas is Particulate reburning of exhaust gas, characterized by comprising an injection valve and a control circuit that outputs a signal to the exhaust gas injection valve and the fuel injection valve to keep the fuel injection valve open for a predetermined period of time.
