Abstract
An object is to provide a diesel engine () capable of reliably preventing an excessive rise in temperature inside a particulate filter () and capable of rapidly enabling driving in a low-rotation and low-load area when there is no possibility of excessive rise in temperature. A diesel engine () includes a diesel engine () exhaust emission purifier (). The diesel engine () exhaust emission purifier () includes a particulate filter () and a controller () for forcibly removing a particulate accumulable in the particulate filter (). The controller () is configured to prohibit the diesel engine () from entering a predetermined low-rotation and low-load area if a load rotation changes when the particulate filter () has a temperature that is equal to or higher than a first predetermined temperature Tand when the particulate is accumulated in an amount that is equal to or more than a predetermined amount.
