関の排気浄化装置。The exhaust pipe of an internal combustion engine is divided into a first branch pipe and a second branch pipe in the middle, and the first branch pipe and the second branch pipe are honeycomb type particulates with both ends closed alternately in a staggered manner. A connecting pipe with a built-in collection filter is used for communication, and the exhaust gas flowing through one of the branch pipes is passed through the connecting part of the connecting pipe to the first and second branch pipes. A pipe switching valve is provided to control the flow to the downstream side of the other branch pipe, and an exhaust pressure sensor and a burner are provided in the communication pipe near both ends of the particulate collection filter, so that the particulates flow to the downstream side of the other branch pipe. The burner is ignited when the measured pressure of the exhaust pressure sensor exceeds a set value, and the direction of the exhaust gas flowing through the communication pipe is then reversed by the pipe switching valve. Exhaust purification device for internal combustion engines.
