  • Exhaust gas recycling system for an exhaust gas turbocharged engine
    Patent number: 4956973
    Abstract: The invention relates to a super-charged fuel-injected internal combustion engine with an exhaust gas driven turbocharger and exhaust gas recycling. To increase the volume of recycled exhaust gases by means of an increase in the pressure drop between the pressure in the exhaust gas line upstream of the turbine and the pressure in the engine charging air line downstream of the compressor, a pressure control valve is provided in either the exhaust line downstream of the turbine or at the compressed air line of a bypass line bridging the compressor.
