るデイーゼルエンジンの排気浄化装置。 A particulate trap filter is installed coaxially with the engine exhaust passage in the middle of the straight passage, and a secondary fuel injection device for filter regeneration is installed upstream of the trap filter in the exhaust passage. In the exhaust purification system for a diesel engine, the fuel injector of the secondary fuel injection system is arranged so as to inject the secondary fuel from the side of the exhaust passage in the opposite direction at a predetermined angle with respect to the flow of exhaust gas. An exhaust purification device for a diesel engine, which is characterized by the following:
