A method and a configuration are provided for cleaning exhaust gas in an exhaust gas system flowing from a gasoline engine. An air/fuel mixture is preferably supplied to the gasoline engine by direct injection. In order to provide improved cleaning, the exhaust gas flows successively in the exhaust gas system through at least one honeycomb body with a catalytically active coating, preferably a three-way coating, and a particle filter with a coating storing at least one pollutant component, in particular hydrocarbon, carbon monoxide and/or nitrogen oxide, at least from time to time. In addition to collecting soot particles, in particular the particle filter advantageously carries out supplementary oxidation of residual hydrocarbons as well as carbon monoxide during a cold start phase, and supplementary reduction of residual nitrogen oxides when the gasoline engine is operated under load.
