The 4- and 5-axis universal machines, for example, can machine or manufacture delicate components. [33] Another mainstay is the construction of special machines for transfer lines. [ 32 ] Among the assembly systems distributed by Grob-Werke are systems for stator production using hairpin technology, rotor production, and battery module assembly ...
This reduces repair costs as a single failed head on a single cylinder can be changed instead of a larger, much more expensive unit fitting all the cylinders. Such a design also allows engine manufacturers to easily produce a 'family' of engines of different layouts and/or cylinder numbers without requiring new cylinder head designs.
Shell molding was developed as a manufacturing process during the mid-20th century in Germany. It was invented by German engineer Johannes Croning. [ 3 ] [ 4 ] Shell mold casting is a metal casting process similar to sand casting, in that molten metal is poured into an expendable mold.
A short block is an engine sub-assembly comprising the portion of the cylinder block below the head gasket but above the oil pan, [4] which usually includes the assembled engine block, crankshaft, connecting rods, and pistons with piston rings properly installed. [5]
The Cologne V6 was designed to be compatible in installation with the Ford Taunus V4 engine, having the same transmission bolt pattern, the same engine mounts, and in many versions, a cylinder head featuring "siamesed" exhaust passages, which reduced the three exhaust outlets down to two on each side. The latter feature was great for ...

The shape of the combustion chamber, intake ports and exhaust ports are key to achieving efficient combustion and maximising power output. Cylinder heads are often designed to achieve a certain "swirl" pattern (rotational component to the gas flow) and turbulence, which improves the mixing and increases the flow rate of gasses. The shape of the ...
