Internal combustion engine operating method for vehicle i.e. motor vehicle, involves operating exhaust valves in phase-delayed manner with respect to one another for balancing different exhaust gas counter-pressure levels

摘要

The method involves operating exhaust valves (3, 4) in a phase-delayed manner with respect to one another for balancing different exhaust gas counter-pressure levels, where the exhaust valves are provided in a cylinder head of a cylinder (2) in an internal combustion engine (1) of a motor vehicle and attached to exhaust-gas turbochargers (7, 8). A part of the exhaust gas from the internal-combustion engine is guided to the exhaust-gas turbocharger.
