摘要： In an engine, an exhaust gas purifying device and a regeneration device, there are provided detectors for detecting working states thereof, such as a rotational sensor, a cooling water temperature sensor, an intake temperature sensor, exhaust gas temperature sensors, pressure sensors, and opening degree sensors. When a trouble occurs in any of the sensors other than the pressure sensors among them, a light degree of operation restrictions is performed for restricting a rotational speed of the engine while it can be determined that particulate matter is not excessively accumulated in a particulate matter removing filter from a detection value of the pressure sensors. On the other hand, when the particulate matter is excessively accumulated in the particulate matter removing filter or when any of the pressure sensors has a trouble, a heavy degree of the operation restrictions accompanied by a fuel injection quantity restriction of the engine is performed.

摘要： A cover for the upper end of an exhaust stack pipe comprises a curved cover pipe of greater diameter than the stack pipe. The curved cover pipe has a proximal end to fit over the end of the stack pipe and a distal end from which exhaust gases are discharged. The cover pipe is shaped to prevent rain from falling directly onto the end of the stack pipe. A flow diverter of lesser diameter than the cover pipe is mounted within the proximal end of the cover pipe to overlie the end of the stack pipe. The flow diverter comprises an extension tube for mounting onto the end of the stack pipe having lateral openings and a tapering deflector extending into the extension tube to divert exhaust gases to flow into the cover pipe through the lateral openings in the extension tube.
