ABSTRACT:
A device for fresh-gas supply for a turbocharged, compression-ignition, reciprocating-piston internal-combustion engine is provided. The engine has fresh-gas supply pipe and exhaust gas manifold pipe, between which an EGR device is installed. A tubular inside space section of the fresh-gas supply pipe located downstream of a turbocharger has a compressed-air connection with a volume control device, and a butterfly valve for controlling throughflow. Operation of the butterfly valve is controlled by an electronic control unit of the engine which processes sensor signals. A control valve of the EGR device, which is electronically controlled and controls the exhaust gas throughflow volume, is connected to the electronic control unit for synchronized operation of the butterfly valve with the volume control device.
