ATTORNEYS LIQUID-COOLED SUPER-CHARGED INTERNAL COMBUSTION ENGINE The present invention relates to a liquid-cooled supercharged intemal combustion engine. The aim underlying the present invention essentially consists in simplifying an internal combustion engine of this type from a structural point of view and to constitute the same more compact. For this purpose, according to the present invention provision is made that the line for the super-charged combustion air and the line for the cooling liquid are connected, prior to entry into the engine, to an elbow housing which is provided with two channels having a common separating wall for the heat-exchange.
A guide wall is dispensed with by the combination of the two lines in the elbow housing. Both the structural space and the weight of the engine as well as the price thereof are advantageously reduced thereby.
Additionally, the cooling of the charging air is improved and such a cooling can be achieved even in the absence of a charging air cooler, properly speaking.
Since also the intermediate space between two structurally separate lines, which has to be present nonnally by reason of the casting shrinkage and the necessary tolerances, is obviated by the present invention, a particularly compact type of construction of the internal combustion engine results. This advantage is particularly important for V-type engines in which relatively little space is available for the lines in the V-space.
The aforementioned intermediate space forms a dirt-collecting comer which is accessible only with difficulty for painting and subsequent cleaning- This disadvantage is also avoided by the present invention.
The elbow housing for the two channels may be formed, for example, by a pipe with inserted separating wall.
However, two half, dish-shaped housing parts may be the cooling water, the charging air is preheated by the present invention for starting at lower external temperatures. The starting operation is thereby facilitated.
ln order to be able to match the sealing between elbow'and engine housing to the different requirements for liquid and air,
according to a further feature of the present invention, a tubu larly shaped intermediate piece is provided that is inserted in a fluidtight manner both at the engine in the inlet aperture of the cooling liquid channel for a cylinder as also'into a connecting aperture of thecooling liquid channel in the elbow housing. The sealing for the air channel between the elbow and en'- gine housing can thus be realized' separately, for example, softly with respect to the liquid seal. The arrangement accord ing to the present invention is advantageous also for such types of internal combustion engines which include several cylinder heads arranged in rows, for example, per cylinder one head. The various tolerances of several cylinder heads can be compensated for with respect to a common elbow housing by the softly constructed sealing means for the charging air.
Particularly with internal combustion engines having several cylinder heads, it is desirable that an individual cylinder head can be disassembled without having to remove theientire line system for the cooling liquid, charging air and exhaust gases.
ln order to fulfill this requirement also with an internal combustion engine having an elbow housing according to the present invention, it is further proposed that the intermediate.
piece is arranged lowerable into the engine housing. For this purpose, the intermediate piece may be provided with an outwardly projecting abutment part that is externally accessible through'an aperture of the engine housing.
Before the cylinder head is disassembled, the intermediate piece can be brought externally into its recessed position. It is also avoided thereby that the cooling liquid or individual drops thereof can reach the sealing places for the charging air channel and from there possibly into the cylinder.
The intermediate piece can be stopped in its operating position by a detachable abutment part. This can engage in a simple manner at the outwardly extending abutment part of the intermediate piece.
The detachable abutment part can be made in one piece with a detachable cover or with a detachable hood at the engine housing. The detachable abutment part may be arranged, for example, at a control housing coveri The construction of this cover, together with the abutment is simplified if the abut ment part of the intermediate piece extends through the associated aperture of the engine housing.
The intermediate piece may be constructed in one piece with-its abutment part if the cross section of the associated aperture in the engine housing forms an open U.
Accordingly, it is an object of the present invention to provide a liquid-cooled super-charged internal combustion engine which avoids by simple means the aforementioned shortcomings and drawbacks encountered in the prior art.
Another object of the present invention resides in a liquidcooled super-charged internal combustion engine which is structurally simplified and provides greater compactness.
A further object of the present invention resides in a liquidcooled super-charged internal combustion engine in'which a separate partition or guide wall between the two lines for the cooling liquid and charging air may be dispensed with.
A still further object of the present invention resides in a liquid-cooled super-charged internal combustion engine in which the cooling of the charging air is improved even'in the absence of a charging air cooler.
Still another object of the present invention resides in a liquid-cooled super-charged internal combustion engine in which a particularly favorable space utilizationis created with V-type engines, avoiding dirt-collecting corners, which are difiicult to reach;
A still further object of the present invention resides in a liquid-cooled super-charged internal combustion engineof the aforementioned type in'which cross-sectional reductions of the channels are avoided as much as possible, the charging air can be preheated; and the seals between the elbow and engine housing can be matched to the different requirements forthe liquid andair media.
These and further objects, features, and advantages of the presentinvention will become more obvious from the following description when taken in connection with the accompanying drawing which shows, for purposesof illustration; one embodiment in accordance with the present invention; and wherein:
H0. 1 is a partial cross-sectional viewthrough the left cylinder row of'a V-type internal combustion engine according to the present invention, and
FIG. 2 is a partial cross-sectional'view'through the right cylinder row of the engine illustrated in FIG. 1.
Referring'now to the drawing wherein like reference numerals are used'throughout the two views"todesign'ate like parts, reference numeral 10 designates therein a part of the crankcase of the left cylinder row generally designated by reference numeral 11. An individual cylinder head generally designated by reference numeral 12 for the working cylinder 13 is mounted on the crankcase part 10.
The inlet channel 16 for "the charging air and the inlet channel 17 for the cooling liquid terminate at the separating surface l4'ofthe cylinder head 12 leading to" an elbow"ho'using generally designated 'by reference numeral 15 and located within the area of the V of the engine. v
The orifice of the cooling liquid channel 17 is formed by a cylinder 18 into which a tubularly shaped intermediate piece 19 is displaceably inserted. The intermediate piece I9 is sealed with respect to this cylinder 18 ina fluidtight' manner by an annular seal 20.
A control housing 21 is mounted over the cylinder head 12 which is accessible by way of a cover 22.
The elbow housing 15 is subdivided by a separating wall 23 into a cooling liquid channel 24 and into a charging air channel 25. The charging air is cooled during normal operation by the separating wall 23. During the starting of the internal combustion engine with a heating installation for the preheating of the cooling liquid, however, the charging air is heated for facilitating the starting operation.
The manner of securing the elbow housing at the cylinder head can be seen from FIG. 2 in connection with the right cylinder row, which corresponds as to the securing to the left row. Parts corresponding to FIG. 1 are designated in H0. 2 with the same reference numerals but using the suffix a. The separating wall 230 of the elbow housing 15a is provided with passage bores 26a for the passage of the securing bolts 27a. The cross section of the channels 24a and 25a is not reduced by this bolt arrangement.
As can be seen from FIG. 1, the tubular-shaped intermediate connecting piece 19 is displaceably inserted into a connecting aperture 28 in the elbow housing 15. The aperture 28 is in communication with the liquid channel 24. The intermediate piece 19 is sealed in a fluidtight manner with respect to the elbow housing 15 by a further annular seal 29.
The intermediate connecting piece 19 is provided with an outwardly extending abutment part 30 which extends outwardly through an aperture 31 of the cylinder head. The abutment part 30 is displaceable in the aperture 31. The aperture 31 terminates in the longitudinal direction of the intermediate connecting piece 19 in the separating surface 14.
The portion of the abutment 30 at the intermediate piece 19 which projects out of the cylinder head l2, abuts in the illustrated operating position against a fixed abutment part 32 of the control housing 21.
After the disassembly of the control housing 2!, the intermediate piece 19 can be inserted or recessed limited by the abutment part 30 to such an extent into the cylinder head l2 or into the cylindrical part 18 thereof that its end face 33 adjacent the elbow housing 15 lies in the same plane as the separating surface 14 or is recessed with respect thereto. Thereafter, the cylinder head 12 can be disassembled in the direction of the cylinder axis.
