METHOD OF OPERATING AN INTERNAL COMBUSTION ENGINE COUPLED TO A GENERATOR

摘要

A method of operating an internal combustion engine coupled to a generator in the event of a grid fault of a power supply grid connected to the generator, in particular in the event of a dynamic grid voltage drop, wherein the internal combustion engine includes a turbocharger having a compressor in an air feed duct of the internal combustion engine and an exhaust gas turbine coupled to the compressor in an exhaust gas duct of the internal combustion engine, wherein there is provided at least one bypass valve for bypass of the compressor and/or for bypass of the exhaust gas turbine, wherein upon or after detection of the grid fault the at least one bypass valve is at least temporarily actuated.

1. A method of operating an internal combustion engine coupled to a generator in the event of a grid fault of a power supply grid connected to the generator, in particular in the event of a dynamic grid voltage drop, wherein the internal combustion engine includes a turbocharger having a compressor in an air feed duct of the internal combustion engine and an exhaust gas turbine coupled to the compressor in an exhaust gas duct of the internal combustion engine, wherein there is provided at least one bypass valve for bypass of the compressor and/or for bypass of the exhaust gas turbine,
wherein upon or after detection of the grid fault the at least one bypass valve is at least temporarily actuated, wherein the ignition in the internal combustion engine is deactivated upon or after detection of the grid fault, wherein the ignition in the internal combustion engine is activated again after the grid fault disappears, wherein the at least one bypass valve has a first position prior to detection of the grid fault, wherein upon or after detection of the grid fault the at least one bypass valve is set to an actuation position differing from the first position, wherein the at least one bypass valve is set to a position differing from the actuation position after the grid fault disappears.
