| 20100000475 | ARRANGEMENT FOR HEATING OIL IN A GEARBOX - An arrangement for warming the oil in a gearbox in a vehicle powered by a combustion engine. A first pipe system with a first flow device which makes possible circulation of oil from the combustion engine through a heat exchanger. A second pipe system with a second flow device makes possible circulation of oil from the gearbox through the heat exchanger. A control device controls the flow devices so that flow of oil through the heat exchanger is obtained in situations in which the oil in the gearbox is at a too low temperature with respect to a desired temperature. The motor oil in the combustion engine can thus be used for heating the oil in the gearbox during cold starts of the combustion engine. | 01-07-2010 |
| 20100006043 | COOLING ARRANGEMENT AT A VEHICLE - A cooling arrangement for a vehicle which is powered by a combustion engine. The cooling arrangement includes an air passage through which air flows in a specific direction, and at least three cooling elements to effect cooling of a medium. The three cooling elements are arranged one after another in the air passage such that at least part of the air which flows through the air passage flows successively through all of the cooling elements and cools the media in the respective cooling elements. The cooling elements are arranged one after another in the air passage in a sequence which is related to the temperature of the media in the respective cooling elements such that the air which flows through the cooling elements in the air passage cools a succession of media, each media in succession is at a higher temperature than the one preceding it. | 01-14-2010 |
| 20100089088 | COOLING ARRANGEMENT FOR AIR OR GAS INPUT IN A VEHICLE - The present invention relates to a cooler arrangement in a vehicle powered by a combustion engine. The cooler arrangement comprises a first cooling element for cooling a first medium in the form of a circulating coolant, and a radiator fan adapted to generating an air flow through the first cooling element for cooling the coolant when it circulates through the first cooling element. The cooler arrangement comprises also a tubular casing adapted to serving as a flow passage for the air which passes through the first cooling element and at least one further cooling element for cooling a second medium, which further cooling element is arranged in the flow passage at a position downstream of the first cooling element with respect to the intended direction of flow of the cooling air through the flow passage. | 04-15-2010 |
| 20100218735 | ARRANGEMENT FOR COOLING OF OIL IN A GEARBOX FOR A VEHICLE - An arrangement for cooling oil in a gearbox in a vehicle which is powered by a combustion engine, the arrangement including an oil cooler, an oil system configured to circulate oil between the gearbox and the oil cooler, and a coolant circuit configured and operable to lead coolant to the oil cooler. The coolant circuit includes a radiator element for cooling the coolant and a line to lead the cooled coolant from the radiator element to the oil cooler. The coolant circuit has a flow-regulator to regulate the coolant flow through the radiator element for imparting to the coolant a temperature which makes possible a desired cooling of the oil in the oil cooler. | 09-02-2010 |
| 20100242929 | ARRANGEMENT AND METHOD FOR THE RETURN OF EXHAUST GASES IN A COMBUSTION ENGINE - An arrangement and a method for recirculation of exhaust gases of a combustion engine. A return line returns exhaust gases to the combustion engine. An EGR cooler device cools the exhaust gases before the gases are led to the combustion engine. A container gathers condensate which forms in the EGR cooler device. A line connects the container to a flow section for the exhaust gases in the EGR cooler device. A driver leads condensate from the container into the flow section for the exhaust gases in the EGR cooler device. | 09-30-2010 |
| 20100263369 | ARRANGEMENT AT A SUPERCHARGED COMBUSTION ENGINE - An arrangement for a supercharged combustion engine includes a first compressor compressing air in the engine air inlet line as a first stage and a second compressor compressing the air in the inlet line as a second stage, a first coolant-cooled charge air cooler cooling the air after it has been compressed in the first stage and before it is compressed in the second stage, and an air-cooled charge air cooler cooling the compressed air when it has been compressed by the first stage, a second coolant-cooled charge air cooler cooling the compressed air after it has been compressed in the second stage and before it is compressed in the air-cooled charge air cooler. Exhaust gases in an exhaust line from the engine drive turbines which operate the compressors. A return line from the exhaust line and connected into the inlet line has a cooler for the exhaust gases before mixing the gases with the inlet air. | 10-21-2010 |
| 20110000446 | ARRANGEMENT AT A SUPERCHARGED INTERNAL COMBUSTION ENGINE - An arrangement for a supercharged combustion engine for preventing ice formation in a cooler. A first cooling system with a circulating coolant. A second cooling system with a circulating coolant which during normal operation of the combustion engine is at a lower temperature than the coolant in the first cooling system. The cooler in which a gaseous medium for the engine and which contains water vapour is intended to be cooled by the coolant in the second cooling system. A heat exchanger. A valve which can be placed in a first position wherein coolant from at least one of the cooling systems is prevented from flowing through the heat exchanger and in a second position wherein coolant from both of the cooling systems flows through the heat exchanger so that the coolant in the second cooling system is warmed by the coolant in the first cooling system. | 01-06-2011 |
