Exhaust gas post treatment system for nitrogen oxide and particle reduction of an internal combustion engines operated with excess air. An oxidation catalytic converter is disposed in the exhaust gas stream of the engine for converting at least a portion of the nitric oxide of the exhaust gas into nitrogen dioxide. A metering device adds reduction agent to the exhaust gas stream downstream of the oxidation catalytic converter and/or to a partial exhaust gas stream branched off upstream of the oxidation catalytic converter and returned to the exhaust gas stream downstream thereof. The reduction agent is ammonia or a material that releases ammonia downstream of the supply location due to the hot exhaust gas. A particle separator or filter is disposed in the exhaust gas stream downstream of the oxidation catalytic converter and of the supply location, and converts carbon particles accumulated in the separator or filter into carbon monoxide, carbon dioxide, nitrogen and nitric oxide with the aid of nitrogen dioxide in the exhaust gas stream. An SCR catalytic converter is disposed downstream of the separator or filter for reducing nitrogen oxides in the exhaust gas stream into nitrogen and water vapor with the aid of ammonia or released ammonia by selective catalytic reduction.

A compression ignition internal combustion engine having at least one combustion chamber for high ignition pressures. Each combustion chamber comprises a cylinder bore in the crankcase or a cylinder liner in the cylinder bore, a piston, and a cylinder head. Spaces for conveying coolant are disposed in the crankcase such that coolant flows about walls of the cylinder bore or a liner. The cylinder head has coolant chambers. The internal combustion engine has a separate cooled plate disposed between the combustion chamber and the cylinder head. The cooled plate forms a surface cover of the combustion chamber and is connected in a positively engaging and gas tight manner with the crankcase and/or the cylinder liner. Valve seats for at least one inlet valve and at least one outlet valve are disposed in the cooled plate, and at least one injection valve extends through the cooled plate.

A portable data processing device in form of a laptop has a housing provided with a keyboard, a display arranged above the keyboard, a turnable holding element supporting the display turnably about the keyboard. The display is displaceable longitudinally on the holding element so as to be vertically adjustable independently of the turning of the display and so that in an upper end position a free space remains between a lower edge of the display and an upper edge of the housing.
