An engine block arrangement includes an engine block and an exhaust gas system. The exhaust gas system, viewed in the flow direction of an exhaust gas flow, includes an exhaust gas turbocharger, an oxidation catalytic converter, a feed device for a urea-water solution, a particle filter, and an SCR catalytic converter arranged one behind the other. The exhaust gas turbocharger, the oxidation catalytic converter, the feed device for the urea-water solution, the particle filter, and the SCR catalytic converter are situated together on the engine block along one side thereof, the side being oriented essentially perpendicularly with respect to an output side of the engine block.

Cylinder block arrangement with an exhaust gas system

In a cylinder head for a multi-cylinder internal combustion engine, wherein the cylinder head includes between its bottom top and side walls a cooling water space through which intake and exhaust passages extend and also columns with bores for receiving cylinder head mounting bolts and well structures for receiving spark plugs or fuel injectors and the bottom wall delineates at its lower side a combustion chamber for each cylinder, wall structures are cast onto the top side of the cylinder head bottom wall and extend in the circumferential area of each combustion chamber in transverse and longitudinal directions between adjacent columns with which they are integrally formed and at least the transverse wall structures extend upwardly and join the top wall and the intake and exhaust passages extend through, and are joined to, the longitudinal wall structures.

Cylinder head for a multi-cylinder internal combustion engine

In a bucket tappet guide structure for a valve tappet of an internal combustion engine having a bucket tappet slideably disposed in a tappet receiving bore, wherein the tappet has a chamfered front end providing for a tappet front face having a smaller diameter than the tappet body, a guide bore is disposed in front of the tappet bore and concentric therewith, the guide bore having a diameter which is larger than the diameter of the tappet bore, however by less than the difference between the diameter of the tappet body and the tappet front face so as to facilitate insertion of the bucket tappet into the tappet bore.

Bucket tappet guide

A cylinder head for a multi-cylinder internal combustion engine with a cylinder head block which bounds a cooling water space, is closed at the top by a cylinder head cover plate and has tubular chambers extending in the direction of the cylinder axis to accommodate a spark plug, an injection nozzle or an injection nozzle with precombustion chamber. A camshaft space is located above the cover plate with devices for valve control, and a bearing pedestal to accommodate at least one camshaft is provided in the camshaft space. The bearing locations for the camshaft are covered by bearing covers. In order to reduce the manufacturing requirements and, furthermore, to minimize the noise radiation caused by the cylinder head side walls, a split plane formed between the cylinder head block and the bearing pedestal extends at the level of the upper chamber edge.
