Definitions
- the invention relates to a method for producing a cylinder head for an internal combustion engine, in particular for a gasoline engine with direct injection, in particular a motor vehicle, according to the preamble of claim 1.
- the present invention is therefore based on the object of providing a method of the type mentioned above, wherein the disadvantages mentioned above are overcome and the smallest possible tolerance for displacement, combustion chamber depth or compression ratio is achieved.
- the cylinder head is produced with an oversize on the crankcase side, that the volume of all the combustion chambers of the cylinder head assigned to the respective cylinders and from this an average value V, s ⁇ is determined, so that this volume V, s ⁇ with a desired volume for the Combustion chamber V S0LL is compared and, depending on this comparison, material is removed more or less mechanically at the cylinder head on the crankcase side in such a way that the sum of all cylinders results in a combustion chamber volume which comes as close as possible to a desired combustion chamber volume.
- This has the advantage that a small scatter with regard to the compression ratio or the displacement is achieved.
- a deviation of a combustion chamber depth from the target value can be achieved in a range of only ⁇ 0.05 mm
- the volumes of the combustion chambers of the cylinder head assigned to individual cylinders are expediently determined using an optical method.This is preferably carried out in a production line of the cylinder head, with a dimension of each cylinder head which is to be mechanically removed from the crankcase side being transmitted to a corresponding downstream processing station
- the cylinder head is produced with an oversize of 0.5 mm on the crankcase side before measuring the combustion chamber volumes .
- a desired combustion chamber volume is expediently selected as the volume V S0LL , taking into account the oversize of the cylinder head on the crankcase side. Only the oversize is then mechanically removed if the deviation of the volume V, s ⁇ from the volume V S0LL is less than a predetermined value. If V, s ⁇ is significantly larger or smaller than V S0LL , more or less than the excess is mechanically removed on the combustion chamber side of the cylinder head
- the cylinder head 10 shown in the single figure comprises individual intake ducts 12, individual exhaust ducts 14 and a combustion chamber side 16 on the crankcase side Cylinder head height 20 determines a combustion chamber depth 22
- each combustion chamber is now 18 V ,, V 2 , V n, for example using an optical method, such as a digital fringe projection based on micromirror, determined
- an average value V, s ⁇ is determined for the volume values V 1 f V 2 , V n of the combustion chambers 18 of the cylinder head educated.
- This average value V, s ⁇ is compared with a desired value for the total volume of all combustion chambers V S0LL which takes into account the b r e r ⁇ nraum worne excess.
- V, s ⁇ and V S0LL match exactly or if the deviation lies within a predetermined range, then the excess is precisely milled away on the combustion chamber side 16 of the cylinder head 10.
- the determined volume V, s ⁇ does not match the target value V SO L , depending on the position, more or less than the excess is milled away such that after milling, the mean value of the volume of the combustion chambers is a target value for the volume of the combustion chambers without excess corresponds as closely as possible.
- the dimension "cylinder head height" 20 is deliberately machined to maintain a predetermined combustion chamber volume within narrow limits, deviating from a standard dimension.
