PROBLEM TO BE SOLVED: To provide an engine capable of accurately achieving an exhaust gas state in correspondence with an operation state during regeneration operation of an exhaust emission control device.SOLUTION: A DPF 45 for purifying exhaust gas is provided in an engine 100. The engine 100 performs regeneration operation for removing PM captured by the DPF 45. The engine 100 includes an engine body 10, an exhaust valve 43, an ECU 90, and an operation state detecting section (an engine speed detecting section 71 and a fuel injection amount detecting section 72). The DPF 45 is arranged in the engine body 10. The exhaust valve 43 is disposed in an exhaust passage of the engine body 10, and can be adjusted to an optional opening. The ECU 90 can control the opening of the exhaust valve 43. The operation state detecting section detects an operation state including a fuel injection amount and engine speed of the engine body 10. The ECU 90 controls the opening of the exhaust valve 43 in correspondence with the detection result of the operation state detecting section.SELECTED DRAWING: Figure 1 |
