摘要： The purpose of the present invention is to provide a diesel engine that can be smoothly started even in a situation where a plunger has become difficult to rotate due to sticking of the plunger that is caused by a fuel film formed on the outer periphery of the plunger. When a key switch 80 is operated from an off-position to an on-position, a control unit 70 of this diesel engine 1 controls an actuator 48 so as to cause a rack 45 to perform a predetermined operation X. If the rack 45 cannot complete the predetermined operation X within a predetermined amount of time Ta, on condition that the key switch 80 is held at a start-position, the control unit controls a starter 60 so as to cause a plunger 34 to perform a preparatory stroke operation whereby the plunger 34 is caused to perform a stroke operation, and the stroke operation by the plunger 34 is stopped before the diesel engine 1 starts.

摘要： It is an object of the present invention to make an improvement of a fuel consumption and an avoidance of an engine oil dilution compatible, at the time of renewal of an exhaust gas purification device 50. An exhaust gas purification system of the present invention is provided with the exhaust gas purification device 50 which is arranged in an exhaust gas route 77 of a common rail type engine 70, and at least one of an intake air throttle device 81 and an exhaust gas throttle device 82 which are arranged in intake and exhaust systems 76, 77 of the engine 70. The exhaust gas purification system executes an auxiliary renewing mode which raises a temperature of an exhaust gas from the engine 70 by actuating at least one of the intake air throttle device 81 and the exhaust gas throttle device 82 in the case that a clogged state of the exhaust gas purification device 50 becomes equal to or more than a prescribed level. The exhaust gas purification system executes a forced renewing mode which supplies a fuel into the exhaust gas purification device 50 by a post injection E in the case that the clogged state of the exhaust gas purification device 50 is not improved even by executing the auxiliary renewing mode.
