Abstract
In a method for turbocharging an internal combustion engine multiple turbochargers are arranged in parallel for supplying turbocharged air to the cylinders of the internal combustion engine via a valve device controlling distribution of the turbocharged air to the cylinders. Each cylinder receives turbocharged air from only one turbo charger at a time and each turbo charger supplies one or more cylinders with turbocharged air. The turbochargers are activated and deactivated according to operational states of the engine. At least one cylinder is switched with the valve device from a supply of turbocharged air of one turbo charger to a supply of turbocharged air of another turbo charger when activating and deactivating the turbochargers.
