    摘要： A control apparatus to be applied to an internal combustion engine (1) which is provided with a turbocharger (9) for supercharging an intake air by utilizing an exhaust gas energy, and a recovered energy amount adjusting device (21) for adjusting an energy amount recovered from the exhaust gas by the turbocharger, is provided with an operation control device (19) for controlling an operation of the recovered energy amount adjusting device in such a manner that the recovered energy amount is adjusted in correspondence to a temperature adjusting state of a temperature adjusted subject (16) arranged in an exhaust gas passage (4) in a downstream side of the turbocharger, and an output adjusting device (19) for adjusting an output of the internal combustion engine so as to compensate for a change of an output of the internal combustion engine which is expected in accordance with an adjustment of the recovered energy in correspondence to the temperature adj ustment state by the motion control device.

    摘要： An exhaust gas purification system for an internal combustion engine includes an engine (2, 2A, 2B, 2C, 2D, 2E) capable of fuel combustion at lean air-fuel ratios, a catalyst (18, 18A, 4B, 4C, 6D, 6E) constructed of zeolite carrying at least one kind of metal selected from transition metals and noble metals to reduce NOx under oxidizing conditions and in the presence of HC, engine operating condition detecting means for detecting the current engine operaing condition, engine operating range determining means (104, 106, 216, 218, 104A, 204B, 102C-112C, 202C, 103D, 104D, 106D, 202D, 103E, 104E, 106E, 202E) for determining whether or not the current engine operating condition is within an insufficient HC amount range, and an HC amount control means (108, 110, 220, 222, 108A, 206B, 113C, 114C, 203C, 204C, 105D, 107D-112D, 203D, 208D, 105E, 107E-109E, 203E, 204E) for controlling the amount of HC included in the exhaust gas when the engine operating range determining means determines that the engine operating condition is within the insufficient HC amount range. The HC amount control means degrades atomization or evaporation of fuel injected from a fuel injection valve to thereby generate unburned fuel and to increase the HC amount in the exhaust gas, so that the NOx purification rate of the catalyst is improved.
