摘要： [Object] To provide to an engine device that reduces the occurrence of malfunction of electrical components disposed in an exhaust-gas purification device due to heat. [Means of Realizing the Object] An engine 1 includes an exhaust-gas purification device 2. The exhaust-gas purification device 2 purifies exhaust gas. The exhaust-gas purification device 2 includes electrical components 44 and 51 to 53. The electrical components 44 and 51 to 53 detect the states of the exhaust-gas purification device 2. The engine 1 includes a cooling-water circulation mechanism for circulating cooling water for the engine 1. Further, a portion of the cooling water circulated by the cooling-water circulation mechanism cools the electrical components 44 and 51.

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.
