Abstract

A protective device for a spark-ignition gas engine is provided, which engine has a throttle valve for controlling a gas/air mixture and has an exhaust-gas turbocharger with a turbine that is associated with a throttle member for exhaust gas. A detection unit is configured to detect an actual differential pressure across the throttle valve, and a control unit is configured to change the position of the throttle member based on the actual differential pressure. The throttle member for the exhaust gas is provided only downstream of the turbine in relation to the flow direction of the exhaust gas. A method for regulating an exhaust-gas throttle member, connected downstream of a turbine of an exhaust-gas turbocharger, is also disclosed.
