Abstract

In an engine device provided with an engine which serves as a power source, an exhaust gas purifying filter device which is arranged in an exhaust gas path of the engine, and control means which executes a low rotation control for lowering an engine speed to a predetermined first low rotating speed at a time when a previously set low rotation condition is established, the control means is structured such as to maintain the engine speed at a second low rotating speed which is higher than the first low rotating speed, for suppressing a reduction of an exhaust gas temperature at a time when both of the low rotation condition and a previously set forced regeneration condition are established.
