Method for braking a motor

The engine braking method involves measuring exhaust-gas counter-pressure and charge air pressure. A position of throttle device to obtain predetermined braking action is determined based on measurement of exhaust-gas counter-pressure and charge air pressure. The exhaust-gas counter-pressure and charge air pressure are controlled by adjusting the throttle device corresponding to previously determined position of throttle device. An independent claim is also included for an engine braking device of multi-cylinder internal combustion engine of vehicle.
