摘要： An exhaust gas cleaning system for an engineering vehicle, such as a hydraulic excavator, is capable of performing manual regeneration control of a regeneration fuel injector 40 that is started only under the following conditions: a manual regeneration starting switch 39 is enabled; an engine control dial 2 commands a low-speed idle revolution speed; and a gate lock lever 22 is switched to a second position B at which generation of control pilot pressures a through f by use of remote control valves 25, 26, and 27 is disabled. Even when the manual regeneration control is being executed, if the gate lock lever 22 is switched to a first position A, the manual regeneration control immediately ends. As a result, the manual regeneration control of a filter for collecting particulate matter included in the exhaust gas and the operation of the work system do not influence each other.

摘要： An exhaust gas post-treatment system for a vehicle is provided, which in the course of regeneration ascertains whether or not there is any object approaching a body of the vehicle from behind. A filter is arranged in an exhaust passage of an engine to trap PM therein. A trapped and deposited PM amount sensing device senses a deposited amount of PM deposited in the filter. A fuel injector burns and removes PM deposited in the filter to conduct regeneration of the filter. A rearward monitoring camera monitors a scene rearward of a vehicle body. A display module displays monitoring information from the rearward monitoring camera, and a controller having a regeneration processing unit executes control processing to actuate the fuel injector and to perform regeneration. The controller includes a display continuation processing unit for executing control processing such that during the regeneration by the fuel injector, the monitoring information from the rearward monitoring camera is continuously displayed on a display screen of the display module.

摘要： Before a large amount of PM is deposited in a filter 32, an exhaust gas cleaning system for a construction machine regenerates the filter to avoid a decrease in output due to the exhaust gas pressure rise occurring immediately before the filter is regenerated, and to reduce the likelihood of unusual increases in the internal temperature of the filter due to the combustion of the PM, associated with the execution of the regeneration, and consequential thermal damage to the filter. If a value of a differential pressure across the filter 32 is greater than a predetermined pressure, a controller 4 conducts engine speed control to a predetermined rotating speed Na suitable for the regeneration, then enters forced regeneration automatically, and burns off the PM. When the sensed differential pressure decreases below a predetermined pressure, the regeneration is terminated automatically and the engine 1 is stopped.

摘要： A fuel tank (12) is constructed such that a front flange portion (14A1) of a top surface plate (14A) of a second plate (14) extends outside in relation to a front surface plate (13B) of a first plate (13). As a result, a front surplus space (15A) projected in the upper and lower directions in a range of the front flange portion (14A1) of the top surface plate is formed in the front surface side of the front surface plate. A urea water tank (24) is arranged along the fuel tank (12) in such a manner that a rear side portion thereof enters into the front surplus space. Therefore, the rear side portion of the urea water tank can enter into the front surplus space using the front surplus space formed in the fuel tank (12), thereby increasing the tank capacity without downsizing the article accommodating box (16).

摘要： An engine powered machine is provided with a high-performance exhaust gas purification system and is capable of promptly raising a temperature of an operator's cab to a comfortable temperature. The exhaust gas purification system that makes use of an NOx removal catalyst and a reducing agent is provided with a reducing agent heater for heating a reducing agent, which is stored in a reducing agent tank, with heat of an engine cooling medium and an on/off device for controlling an introduction of the engine cooling medium into the reducing agent heater. When a temperature of the engine cooling medium is higher than a first predetermined temperature, a temperature of the reducing agent in the tank is lower than a second predetermined temperature and a temperature in an operator's cab is lower than a third predetermined temperature, a controller switches the on/off device into a closed state to increase a flow rate of the engine cooling medium to be guided to a heat exchanger of a heating apparatus.
