摘要： In an engine, a controller is configured to fully close the opening of EGR valve when a cut condition is satisfied and variably control the opening when a cut release condition is satisfied. An operating zone is defined as a zone surrounded by a characteristic curve indicating a relationship between rotation speed and torque. The operating zone comprises a high operating zone containing an NTE zone, and a low operating zone that is set at a lower torque side and at a lower rotation speed side with respect to the high operating zone. The cut condition is that an operating condition specified by the rotation speed and the torque is kept within the low operating zone during a predetermined time or more. The cut release condition is that the operating condition falls within the high operating zone.

摘要： An engine device in which an exhaust gas purification device can be assembled adjacent to an engine with high rigidity, and the exhaust gas purification device can be compactly installed. The engine device includes an exhaust gas recirculation device and a common rail disposed on the side on which an intake manifold of the engine is disposed, the exhaust gas purification device disposed on the side on which an exhaust manifold of the engine is disposed, an oil pan disposed on the bottom of the engine, and a support body for linking the exhaust gas purification device to the oil pan, so that the exhaust gas purification device is supported by the oil pan via the support body.

摘要： In an EGR device configured to reflux part of exhaust gas of the engine as EGR gas into intake air of the engine, an EGR valve configured to restrict a flow rate of the EGR gas is closed when rotation speed N of the engine is between a low-speed threshold and a high-speed threshold, and fuel injection rate is between a low-injection rate threshold and a high-injection rate threshold that are set for each rotation speed.
