Abstract

A method for operating an engine of a motor vehicle is provided. The method comprises operating at least one turbocharger, operating a start/stop automatic system which automatically switches off the internal combustion engine when a stop condition is met, and automatically starts the internal combustion engine when a starting condition is met, and when the stop condition is met, delaying the automatic switching off of the internal combustion engine by a predefinable delay time (Δt). In one example, automatic shut off of the engine may be delayed in order ensure adequate cooling of the turbocharger.
