Patent ID: 7826958

Claim:
An arrangement for recirculation of exhaust gases of a combustion engine, the arrangement comprising an air inlet line which supplies air to the combustion engine, an exhaust line which leads exhaust gases out from the combustion engine, a return line extending from the exhaust line to the inlet line to supply and returned exhaust gases to the combustion engine; a flow control comprising an EGR-valve operable to regulate the amount of exhaust gases led through the return line and a control unit operable to control the EGR-valve; and an EGR cooler in the return line and operable to cool the exhaust gases in the return line by a coolant which is used in a cooling system for cooling the combustion engine; a temperature sensor operable to detect the coolant temperature at a point in the cooling system, the control unit being operable to receive information from the temperature sensor concerning the coolant temperature (T), and to decide whether the coolant in the cooling system is at a too low temperature, the control unit being operable to control the EGR-valve so that a larger amount of exhaust gases is led through the return line and the EGR cooler to the inlet line if the coolant in the cooling system is at a too low temperature.
