Patent ID: 8627807

Claim:
An arrangement for recirculation of exhaust gases of a combustion engine in a vehicle, the arrangement comprising an exhaust line for leading exhaust gases out from the combustion engine; a return line connected to the exhaust line for recirculating exhaust gases in the exhaust line to the combustion engine a high-temperature cooling system containing a first high temperature circulating coolant in the form of a liquid medium; an EGR cooler in the high temperature cooling system and configured for being cooled by the first coolant, the EGR cooler being at the return line for subjecting the recirculating exhaust gases in the return line to a first step of cooling by the circulating first high-temperature coolant; a first radiator element in the high temperature cooling system and positioned in a region of the vehicle for air to flow through the first radiator element, the first high temperature coolant passes through the first radiator element so that the high-temperature coolant is cooled by air passing the first radiator element, the liquid medium of the first high temperature coolant, at an intended operating pressure in the high-temperature cooling system has a boiling point above 300° C.; a second cooling system for cooling the engine; a second radiator element in the second cooling system and positioned in a region of the vehicle for having air flow through the second radiator element; the first radiator element being downstream in air flow through the radiator elements from the second radiator element, such that air passing the second radiator element is warmed before the air passes the first radiator element.
