An arrangement for cooling of recirculating exhaust gases of a combustion engine () in a vehicle (). The arrangement comprises a first EGR cooler (), a driving means () adapted to driving air through the first EGR cooler () in order to cool the exhaust gases in a return line () which are subjected to a first step of cooling in the first EGR cooler (), and at least one second EGR cooler () in which the exhaust gases in the return line () are intended to undergo a second step of cooling. The arrangement comprises an air line () which extends at least from the first EGR cooler () to the exhaust pipe () at a location between the turbine () and the exhaust-treating component (), which air line () is adapted to leading warm air from the first EGR cooler () into the exhaust line () at said location.

Arrangement for cooling of recirculating exhaust gases of a combustion engine

At least one cooling device for a motor vehicle is aircooled by an air flow generated by a cooling fan of the motor vehicle. An air flow configuration of the cooling fan is determined by the fan's degree of protrusion from a fan ring running in the circumferential direction of the fan, preferably in air flow communication with a fan cowling. The air flow configuration is optimized in a manner controlled according to need by relocation of a movable portion of the fan ring in an axial direction of the fan. The disclosed method of controlling the air flow configuration is summarized above. A device performing the method and an engine for the motor vehicle including the device are also disclosed.

Method and arrangement for control of cooling and an engine

A cooler device for a motor vehicle including a charge air cooler with a first cooler element, an EGR cooler with a second cooler element arranged substantially in plane with the first cooler element is disclosed. A screening device regulates air flow through the cooler elements. A control mechanism is operable to switch the screening device to and from between an open position and a closed position. A first screening portion allows more air to pass through than a second screening portion when the screening device is in the closed position such that air flow through the first cooler element is limited to a lesser extent than through the second cooler element in the closed position.
