摘要： An exhaust purification system for an internal combustion engine (1) is provided that can maintain the NOx purification rate of a selective reduction catalyst (23) at near the maximum thereof. The exhaust purification system is provided with an oxidation catalyst (21) and CSF (22) provided in the exhaust plumbing (11) of the engine (1), a selective reduction catalyst (23) that is provided in the exhaust plumbing (11) on the downstream side of oxidation catalyst (21) and CSF (22), and selectively reduces NOx in the exhaust, and a NO 2 sensor (43) that detects NO 2 in the exhaust inside of the exhaust plumbing (11) on the downstream side of the selective reduction catalyst (23). An ECU (3) executes NO 2 -NOx ratio decrease processing to cause the NO 2 -NOx ratio corresponding to the ratio of NO 2 to NOx in the exhaust flowing into the selective reduction catalyst (23) to decrease, in a case of a detection value Vno2 from the NO 2 sensor (43) being greater than a predetermined value Vno2_th.

摘要： An EGR control apparatus for an internal combustion engine, which is capable of accurately controlling an inert gas amount and an inert gas ratio 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 and reduced exhaust emissions. The EGR control apparatus includes a low-pressure EGR device, a high-pressure EGR device, and an ECU. The ECU calculates a target low-pressure opening, calculates an estimated value of an in-cylinder low-pressure inert gas flow rate, which is the estimated value of an inert gas amount included in low-pressure EGR gas supplied to the cylinders via an intake passage, calculates a target high-pressure opening using the estimated value, and controls low-pressure and high-pressure EGR control valves, using the target low-pressure opening and the target high-pressure opening.

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.

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.
