摘要： An exhaust purification system for an internal combustion engine is provided that can maintain the NOx purification rate of a selective reduction catalyst at near the maximum thereof. The exhaust purification system is provided with an oxidation catalyst and CSF provided in the exhaust plumbing of the engine, a selective reduction catalyst that is provided in the exhaust plumbing on the downstream side of oxidation catalyst and CSF, and selectively reduces NOx in the exhaust, and a NO2 sensor that detects NO2 in the exhaust inside of the exhaust plumbing on the downstream side of the selective reduction catalyst. An ECU executes NO2-NOx ratio decrease processing to cause the NO2-NOx ratio corresponding to the ratio of NO2 to NOx in the exhaust flowing into the selective reduction catalyst to decrease, in a case of a detection value Vno2 from the NO2 sensor being greater than a predetermined value Vno2_th.

摘要： An EGR control apparatus for an internal combustion engine, which is capable of properly controlling an inert gas amount of two types of EGR gas supplied to cylinders of the engine via two paths different from each other, thereby making it possible to ensure a stable combustion state, reduced exhaust emissions, and improve operability. The EGR control apparatus includes low-pressure and high-pressure EGR devices, and an ECU. The ECU controls the low-pressure and high-pressure EGR gas amounts according to engine speed and demanded torque, and when a combination of engine speed and demanded torque is in a predetermined region, the low-pressure and high-pressure EGR gas amounts are controlled such that inert gas in low-pressure EGR gas exceeds in amount inert gas in high-pressure EGR gas, and the former more exceeds the latter as engine speed is higher or demanded torque is larger.

摘要： Provided is a control device for an internal combustion engine that can execute a sulfur purge in a favorable manner under all conditions without complicating the control action or the engine structure. The process comprises detecting a temperature of the NOx catalytic converter, detecting an exhaust air fuel ratio in the catalytic converter, computing a target exhaust air fuel ratio according to a detected temperature of the NOx catalytic converter, and controlling a fuel injection valve so as to make an actual exhaust fuel ratio agree with the target exhaust air fuel ratio. If the temperature of the NOx catalytic converter is not high enough to enable a sulfur purge, a temperature increase control is executed to increase the temperature of the NOx catalytic converter by suitably changing various engine parameters.

摘要： In a control device for an internal combustion engine provided with a NOX catalytic converter in an exhaust passage thereof, the progress of sulfur purging is computed from the consumption of reducing agent contained in the exhaust gas in the NOX catalytic converter. This computation may be based on the air fuel ratio of exhaust gas upstream of the NOX catalytic converter and the estimated consumption of the reducing agent contained in the exhaust gas or on the difference between the air fuel ratios of exhaust gas upstream and downstream of the NOX catalytic converter. In either case, the accuracy can be improved by taking into account the space velocity of the exhaust gas.
