A heat-resistant filter installed in the exhaust pipe for the purpose of removing soot from exhaust gas in a diesel engine for a vehicle, especially for an automobile, and for adjusting the operating state of the engine. The filter 2 has a layer with a catalytic effect on the surface exposed to the exhaust gas, and the filter 2 has a catalytic layer on the surface exposed to the exhaust gas, and a device that operates periodically to burn off the dust collected on the filter. The present invention is characterized in that it is equipped with a device consisting of exhaust gas return devices 5 to 7 that return the exhaust gas to the intake pipe 4, and that during its operation, this device alternately switches between a state in which exhaust gas is introduced and a state in which it is not introduced. The above-mentioned diesel engine. 2. A diesel engine as described in Claim 1 of the Utility Model Registration Claim, in which the exhaust gas return device is provided with an introduction pipe 5 that guides exhaust gas into the intake pipe 4 of the engine 1, and this introduction pipe has a valve 6. The above-mentioned diesel engine is characterized in that the control device 7 alternately opens and closes the engine. 3. A diesel engine as set forth in claim 1 or 2 of the utility model registration claim, which includes an exhaust gas return device 5
7 is a diesel engine characterized in that it is operated every predetermined running period (distance). 4. A diesel engine as set forth in claim 1 or 2 of the utility model registration claim, which includes an exhaust gas return device 5
7 is a diesel engine that is activated when exhaust gas pressure exceeds a predetermined value.
