Abstract

An exhaust gas return system for an internal-combustion machine which comprises a low-pressure supply line extending from an inlet From the compressor. a high-pressure supply line extends to the internal-combustion machine. From the internal-combustion machine a high-pressure exhaust gas line extends to a turbine. From the turbine a low-pressure exhaust gas line extends to an outlet. The low-pressure exhaust gas line and the low-pressure supply line have connected therewith a low-pressure return line for returning exhaust gas. The high-pressure exhaust gas line has connected therewith a bypass line for utilizing the heat of the exhaust gas produced in the internal-combustion machine for heating the exhaust gas to be returned of the low-pressure return line before the exhaust gas is supplied to the turbine (24), if desired. Thus the cold start phase of the internal-combustion machine can be reduced.
