The invention relates to an arrangement and a method for operating an internal combustion engine (1), wherein a heat exchanger (8) for preheating a lubricant of the internal combustion engine (1) and a catalytic converter (5) are disposed in the exhaust gas line (3). In a cold start phase, at least a partial flow is withdrawn from the exhaust gas upstream of the exhaust gas turbocharger (4) and, therefore, upstream of the catalytic converter (5) via a supply line (7) that can be closed by a closure member (6). Said partial flow is fed to a heat exchanger (8) integrated in an oil sump of the internal combustion engine (1). To offset the reduction in thermal energy, the catalytic converter (5) is also heated by an electric heater (9). Thus, during this first operating phase it is not necessary to increase the operating temperature of the internal combustion engine (1) by changing the operating parameters.
