Abstract
A device for use with a lean-burning internal combustion engine is disclosed. The device is comprised of a means for generating an air/fuel mixture for the cylinders of the engine in order to provide at least stratified and homogenous operation, an exhaust system connected to the engine, and an NOX-adsorbing catalytic converter arranged in the exhaust system. The device additionally has a heat exchanger that is fitted upstream of the catalytic converter, wherein the heat exchanger is used to adapt the temperature of the exhaust gas from the engine to an operating state of the catalytic converter.
