<p><P>PROBLEM TO BE SOLVED: To provide an output control device for an internal combustion engine surely preventing deterioration of an exhaust system components due to excessive temperature rise and suppressing exhaust gas leak from a joint part of the exhaust system components due to excessive pressure rise by directly acquiring temperature rise and pressure rise of an exhaust system due to clogging of DPF (filter) and suppressing engine output. <P>SOLUTION: In the output control device for the engine (internal combustion engine) provided with the DPF collecting particulate matter in exhaust gas in an exhaust system, exhaust pressure PPREDPF before DPF is detected (from S100 to S104), an upper limit value (torque limit TLMT1) of output of an engine is calculated to reduce as exhaust gas pressure increases (S106) according to at least detected exhaust gas pressure (in more concrete, primary delay value PPREDPFF thereof), and engine output is controlled (from S108 to S116) based on upper limit value of calculated output. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
