摘要： PROBLEM TO BE SOLVED: To inhibit NOx emission and deterioration of fuel economy in an acceleration transient state from a fuel cut state in an exhaust gas recirculation device for an internal combustion engine recirculating exhaust gas using a high pressure EGR means and a low pressure EGR means in parallel or changing over the same. SOLUTION: This exhaust gas recirculation device performs transient control performing exhaust gas recirculation using the high pressure EGR means in acceleration from the fuel cut state even if a target operation state is in a region where exhaust gas recirculation is performed using only the low pressure EGR means. The transient control is, however, released, if it is judged that it is in a state where an NOx catalyst 20 can purify NOx. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a technology for inhibiting insufficiency of the amount of EGR gas and inhibiting the generation of NOx in a transition condition when the operation state of an internal combustion engine is shifted from a fuel cut state to another operation state in response to an acceleration demand, which is intended for an exhaust gas recirculation device of the internal combustion engine performing EGR by selectively using a high pressure EGR means and a low pressure EGR means.
SOLUTION: The exhaust gas recirculation device of the internal combustion engine performs EGR by using only the high pressure EGR when the operation state of the internal combustion engine 1 is in a HPL (High Pressure Loop) region, performs EGR by using only the low pressure EGR when the operation state of the internal combustion engine 1 is in a LPL (Low Pressure Loop) region and performs EGR by using both the high pressure EGR and the low pressure EGR when the operation state of the internal combustion engine 1 is in a MPL (Middle Pressure Loop) region. The device controls the opening degree of a low pressure EGR valve 5 to a more valve opening side than the opening degree required for NOx reduction in the shifted operation state when the operation state of the internal combustion engine 1 is shifted from the fuel cut condition to the HPL region or the MPL region in response to the acceleration demand.

摘要： PROBLEM TO BE SOLVED: To suppress a recirculation of huge amount of exhaust of high temperature due to an execution of a temperature rising process for an exhaust emission control device, by an EGR device. SOLUTION: The exhaust emission control system is provided with: a high pressure EGR passage connecting an exhaust passage upstream of a turbine to an intake passage downstream of a compressor; and a low pressure EGR passage connecting an exhaust passage downstream of the exhaust emission control system downstream of the turbine to an intake passage upstream of the compressor, and the system decreases the gas amount of the low pressure EGR during a regeneration process against a filter. The gas amount of the low pressure EGR is decreased while the exhaust emission control device kept a high temperature state by remaining heat of the regeneration process even after the regeneration process against the filter is completed. Therefore, the recirculation of the huge amount of exhaust with high temperature through the low pressure EGR passage is suppressed. COPYRIGHT: (C)2008,JPO&INPIT
