Abstract: A method for operating a motor vehicle internal combustion engine that has an exhaust tract with an exhaust gas purification unit acting catalytically and/or by filtration with which combustion air supplemented by exhaust gas diverging from the exhaust tract is fed to the combustion chambers of the internal combustion engine by exhaust gas branching off from the exhaust tract at a total exhaust gas recirculation rate. The total exhaust gas recirculation rate has a low-pressure proportion diverging downstream from the exhaust gas purification unit and a high-pressure proportion diverging upstream from an exhaust gas turbocharger turbine arranged in the exhaust tract. An essentially decreasing low pressure proportion is set with at least approximately the same operating points of the internal combustion engine with an increasing operating period of the exhaust gas purification unit.

Abstract: A method for operating a motor vehicle diesel engine having an exhaust emission control system is provided. The emission control system includes an oxidation catalytic converter, a particle filter, and an SCR catalytic converter, in which the exhaust gas that is discharged from the diesel engine is passed through the oxidation catalytic converter before passing through the particle filter and the SCR catalytic converter. A regeneration of the particle filter with thermal soot burn-off is occasionally carried out, during which the diesel engine is operated at an air-fuel ratio having a lambda value (?) of at least approximately 1.0, and air is added to the exhaust gas after it exits the oxidation catalytic converter and before it enters the particle filter air, so that soot deposited on the particle filter is burnt-off.
