Method for operating internal-combustion engine, involves detecting lambda value in exhaust gas of cylinders, and controlling spin flap or adjusting device in inlet channel of cylinder depending on lambda value

摘要

The method involves detecting oxygen content of exhaust gas (155) in an exit gas line (120) by lambda sensors (180, 185) of an internal-combustion engine. A spin flap is arranged in an intake air channel, and an adjusting device is provided in an inlet channel of cylinders. Injectors (151-154) are assigned to cylinders, respectively. Lambda value of the exhaust gas of each cylinder is detected. The spin flap or the adjusting device in the inlet channel of the cylinder is controlled depending on the lambda value of the cylinder. An independent claim is also included for a computer program comprising a set of instructions for executing a method for operating an internal-combustion engine.
