United States Patent 2,700,964 HOUSING 0F INTERNAL-COMBUSTION ENGINES Friedrich K. H. Nallinger, Stuttgart, Germany Application September 30, 1949, Serial No. 118,733
Claims priority, application Germany October 1, 1948 14 Claims. (Cl. 123-41.77)
The. present invention relates to a simplified and light weight housing I for aninternal combustion engine.
Accordingly, it is an object of the present invention to provide a simplified and lightweight housing for internal combustion engines. i
The main feature of the present invention lies in the fact that the casting of the engine comprises primarily inner walls, and a lower and upper terminal partition wall, whereby the outer walls, particularly the walls surrounding the cooling. water jacket, are formed primarily of special sheet metal covers which are subsequently connectedto the casting. If the cylinder and the cylinder head are made out of one unitary casting, it is advisable that the. outer sheet metal walls extend uninterruptedly over the cylinder block and the cylinder head. On the other hand, if the cylinder block and the cylinder head are separate castings, then each of the castings should be provided withindividual sheet metal partitions or covers.
The sheet metal partitions or covers may be detachably' connected to the casting in any suitable manner, as by means of screws, or preferably are connected undetachably by welding, soldering or spurting. The spurting may be done, for example, by means of a spurt of the schoch type by means of which the crevices and interstices between the sheet metal jacket and the casting are spurted with metal. The sheet metal partitions or covers are preferably turned flangelike along the edges thereof and are placed between the projecting walls or flanges of the casting. However, theymay also be placed flatly upon the outer walls or upon the outer edges of the flanges of the casting. Furthermore, the sheet metal partitions or walls may be used either as flat plates or possibly with bent edges, or possibly they may be formed, for example, corresponding to the inner walls of the casltiing so as to decrease the volume of the cooling water jac et. t
. By reason of the fact that the castings may be manufactured without outer walls,
shape of the castings. The mould utilized in accordance with the present invention requires only simple cores whereby the casting may be cleaned easily, thoroughly and reliably by means of sand. The simplicity of the forming of the mould considerably reduces the danger of stresses occurring in the casting and therewith the occurrence of waste But above all, a considerable decrease in weight is accomplished. On the one. hand, a portion of the walls which normally have a thicknessyof about /a to 71 of an inch is replaced by sheet metal having a thickness of approximately & or A of an inch, and, on the other hand, the remaining casting walls may be formed of reduced thickness. i i
It is particularly advantageous that the inlet and outlet channels are not brought out to the lateral wall of the cylinder head, as is customary, but instead are brought out to the upper side thereof. On the one hand, an additional simplification of the casting can be obtained thereby, and, on the other hand, the sheet metal jacket laterally surrounding the casting of the cylinder head is not interruped by the channels. 1
Further objects, featuresand advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawing which shows for purposes of illu'stration only several preferred embodiments of the present invention, and wherein:
Figure l is a vertical sectional view-of an engine with a cylinder block and a cylinder head consistingof one Figure 2 is a similar sectional view of an engine with 1t is possible to simplify the 2,700,964 Patented Feb. 1, 1955 ice the cylinder head formed separately from the cylinder block.
Figure 3 is a side view of the engine shown in Figure 2, and
Figure 4 is a sectional view showing another embodiment of the cylinder head.
Referring now more particularly to the drawing, wherein like reference numerals are used throughout the various views thereof to designate like parts, and more particularly to Figure 1, reference numeral l designates the cylinder block and reference numeral 2 the cylinder head. The cylinder block 1 and cylinder head 2 are formed as a unitary casting which is terminated at the lower end thereof by terminal wall 3, and which is terminated at the upper end thereof by terminal wall 4.
The cylinder head is formed essentially by the covering wall 5 for the cylinder space or chamber and the upper terminal wall 4, by the inlet and outlet channels and by the valve guides, of which only one channel 6 and one valve guide 7 is shown in the cross sectional view, which houses the slantwise arranged intake and exhaust valves, of which only one valve 8 is shown in the cross sectional view. The channels 6 thereby extend S-shaped upwardly and terminate in the terminal wall 5. In engines with a carburetor it is preferable that a down draft carburetor located above the cylinder head be used. The internal actuating mechanism (not shown) which may include, for example, a cam shaft arranged above the cylinder head, may be mounted in a special housing located on the. cylinder head, which housing may, in a given case, form at least partly a unitary piece with the cylinder head. The bearing supports 9 for the crank shaft are likewise joined by being cast integrally with the cylinder block, but may also be detachably fastened thereto, it so desired. The bearing itself may .consist of one or of two parts. A hood or trough 10 made of sheet metal is fastened to the lower terminal wall 3 of the cylinder block 1 by screws.
According to the present invention, the outer walls of the cooling water jackets are formed of sheet metal covers 11 and 12. One each of these sheet metal covers is arranged on either side of'the cylinder and extends essentially over the entire length and the height of the casting. The borders or rims of these sheet metal covers which are otherwise flat are bent so as to form flanges 13 and 14, by which the sheet metal covers are emplaced in the openings between the terminal walls 3 and 4 in such a manner that they touch the flange-like projecting edges of these walls. The flanges 13 and 14 are connected with the walls 3 and 4 of the casting in any suitable manner as, for example, by welding, soldering or metal spraying. The frontal sides of the cylinder block may form parts of the casting, or may alsobe formed of sheet metal which may consist of parts emplaced indi vidually or may be formed as parts of the corresponding sheet metal covers 11 and 12, respectively.
The illustrated embodiment according to Figures 2 and 3 differs from the embodiment of Figure 1 in that the cylinder block and the cylinder head form individual separate castlngs.
In the place of the sheet metal covers extending from bottom to top, as shown in Figure 1, corresponding special sheet metal covers 15 and 16 for the cylinder are placed between the terminal walls 3 and 17, and special sheet metal covers 18 and 19 for the cylinder head are placed between the covering walls 20 and 4. All of thesesheet metal covers are connected with the castings in any of the aforementioned ways.
Figure 3 shows a sheet metal cover 16 arranged later- .ally between the flange-like projecting terminal walls 3 and 17, and an end wall or a flange-shaped bridge 21 of the cylinder block. However, in that case, the laterally arranged sheet metal covers 15 and 16 may also extend over the front ends of the cylinder casting.
The cylinder head according to Figure 4 shows an essentially rectilinear inlet and outlet channel 6 which again is controlled by a valve 8 arranged slantingly in a direction opposite of that of the channel 6. In the embodiment illustrated in Figure 4 the outer walls of the cooling water jacket are formed by sheet metal covers 18 and 19 which are curved inwardly following the contours of the inner walls 4, 7, 6 and so as to reduce the volume of the cooling water jacket to the required amount. As contrasted with the embodiments illustrated above, the joining or securing of the sheet metal covers takes'place in a somewhat different manner. The upper border 22 of the sheet metal covers which is connected with the'terminal wall. 4, is bent inwardly, while the lower border 23 of the sheet metal cover rests flatly on the outer border of the terminal wall 20; A corresponding sheet metal cover 19 may be provided at the bore hole 24 which serves for the insertion of a spark plug or the like. The sheet metal cover may also be provided with an opening around which it is also closely connected with a casting unless a special seal or gasket is provided therefor.
The sheet metal covers 15 and 16 for the cylinder block may also beprovided with borders or edges 25 which are bent inwardly.
The present invention may be applied to diesel engines and engines with a carburetor and to all other kinds of internal combustion engines, and is especially suitable for cheap and small engines, and particularly for motor vehicles. Ultimately, the upper covering wall of the cylinder head may also be formed of sheet metal. The designation upper and lower is to be understood as applied to engines having upright cylinders, and is .to be understood correspondingly with engines having a different arrangement of cylinders.
