| 20110030345 | METHOD FOR REDUCING NITRIC OXIDE IN THE EXHAUST GAS FLOW OF INTERNAL COMBUSTION ENGINES - A method is described for reducing nitrogen oxides in the exhaust gas flow of combustion engines, especially a motor vehicle internal combustion engine, wherein an air/fuel mixture in the combustion chamber of the combustion engine is combusted in the presence of a fuel additive and, in the process, the fuel additive decomposes and the exhaust gas flow is guided through at least one catalyst arranged downstream of the combustion chamber. This method is characterised in that a fuel additive is used, which decomposes in the combustion chamber releasing ammonia and the exhaust gas flow containing ammonia is guided through at least one SCR catalyst arranged downstream of the combustion chamber to reduce the concentration of the nitrogen oxides contained therein. The method according to the invention is highly effective in reducing the nitrogen oxide content in the exhaust gas flow of a combustion engine without an exhaust gas aftertreatment system having to be expensively formed and the installation space having to be increased. | 02-10-2011 |

| 20100319638 | COOLING DEVICE FOR ENGINE AND/OR TRANSMISSION OIL, IN PARTICULAR OF AN INTERNAL COMBUSTION ENGINE - A cooling device for engine oil and/or transmission fluid, in particular of an internal combustion engine, has a flow-through oil cooler in an oil trough. The oil cooler is formed by a plate heat exchanger with plate intermediate spaces which route coolant and oil. The plate intermediate spaces that conduct oil have an outer opening region which is arranged on the outer circumference of the plate heat exchanger as inflow region, via which hot oil to be cooled flows into the oil-conducting plate intermediate spaces. Furthermore, the oil-conducting plate intermediate spaces have an outer outflow region which is arranged on the outer circumference of the plate heat exchanger at a distance from the inflow region. The outflow region is connected indirectly or directly to an outer oil line connecting region, via which cooled oil flows out after heat exchange with the coolant. The plate heat exchanger is suspended in the oil trough at a defined spacing from the oil trough walls which surround it. | 12-23-2010 |
