Internal combustion chamber arrangement of combustion chambers (cylinders) of internal combustion engines In the case of internal combustion engines, the degree of stressing capability and high degree of wear resistance of all major components such as bearings, valves, pistons, etc. is entirely dependent on the extent to which the coolant is used Each of the existing combustion chambers of a machine, the dissipation of the resulting amounts of heat takes place.

With the known cooling devices, however, both .diestationary internal combustion engine as well as those for vehicles are often subject to uneven and insufficient heat dissipation. These deficiencies have been addressed by means of special coolant guides in the cold rooms.

So z. B. according to a known proposal, the cooling for the pre-chamber, which is only one particular item of relatively small dimensions, a large internal combustion engine trained in such a way that the, namely annular cooling space, the VVrkammer lying in a disposed between the cylinder and the cylinder plate VVrkammer has narrow passage cross-sections and that while the head wall of the prechamber is formed by the well-known manner by installing a false floor more cooled bottom of the cylinder cover: The entering at the bottom of Zvlinderkühlraumes cooling flow flows to the space in the head wall arranged on the bypass opening, from there then in the plate located in the aforementioned annular pre-chamber with narrow passage cross-section (ring channel), leaves this on the inlet opening oppositely arranged outlet opening and flows from there finally in the cylinder cover refrigerator, -where he is after increased flushing of the formed from your cylinder cover bottom Vorkammerkopfwand then deflected by a above said inflow and between the cylinder head cover wall deflecting wall before it flows through the latter refrigerator.

In this embodiment, in order to protect the cylinder cover against the dangerous action of heat, the combustion chamber is cooled more than the cylinder cover. become. It is not, as in the invention, the cooling of the entire internal combustion engine. The invention is based on a core idea that, in particular in the case of long-term use of the machines, high or full peak power is to the greatest extent possible in each of the combustion chambers. to ensure that the amount of heat produced is both uniform and adequate, and that a cooling stream from its entry into a space assigned to it may be possible only when it has already flowed through its entire mass in its entire extent.

An object of the invention therefore half ordered that in between existing refrigerated existing partitions, for example in piston engines in the head wall of the cylinder cooling chamber or in the bottom of the cylinder head cooling chamber or in the - intermediate plate (seal), for the transfer of the liquid. Are arranged so arranged air, air-like Kühlstromes lfinungen are arranged so that after entering a space assigned to him a cooling flow with at least its main amount is given an outlet possibility only after flowing through the assigned space, d.ll. only when the cooling flow into the space allocated to it has been sufficiently flushed in each of the combustion chambers contained therein.

According to the invention, for this purpose, depending on the arrangement of the inlet and outlet openings (inlets and outlets) at the ends or in the middle of Gesaintraumes-in the partition, the openings for the transition of depending on your given case liquid or gaseous, cooling stream from a Space arranged in another ain the inlet or the outlet opening facing away from the cooling flow to the flow space allocated. Further, the size d of the transfer openings or their passage is preferably held so that the entire amount of cooling air flows through them.

In the drawing, some embodiments of this part of the invention are dagestellt to Zylinderkühlräuinen of reciprocating engines.

The part indicated by a in the figures represents an area of ​​the partition wall, e.g. B. from the top of the Zylinderki'vhlrauines, or your bottom of the Zylinderkopfkühlranmes or the intermediate plate or the seal.

The parts marked b and c in the figures represent those openings which are used for the cooling current transfer. The arrangement of these openings in the sense of b or c or b and c is generally dependent on the one hand on the type and on the other hand also on the size of the given cold rooms. The further openings in the partition shown in the figures (the drawing) are only openings of a very small size, ie around openings with a relation to the passage of the openings to b and c very low passage. Their main purpose is preferably only the balance of the amounts of coolant between the rooms after the machine is turned off. In reciprocating engines, for example, the application of these small connection openings in particular also depends on whether the 'machine is equipped with side or head valves or finit sliders.

With the arrows, the flow direction is symbolized, which is imposed on the cooling flow in the assigned space each by the inventive arrangement of the transfer openings (b, c) at least for its main amount.

With regard to the arrangement and the design of the cooling chambers shown in deal embodiments and the coolant supply and discharge openings as well as those of the Cberleitungs- and connection openings-between the spaces will be noted that they serve only to explain the essence of the subject invention.

In Fig. I, an embodiment is shown, in which both the supply and the Ahfü @ openings are arranged at an end portion of the entire refrigerator. The embodiment according to Fig. Ä corresponds to the Fig. I.

In contrast, in Fig. 3, the cooling-flow supply and discharge openings are arranged in the middle of the overall cooling space. The Kühlstronlüberleitungsöffnungen are inventively in the partition at both end portions of the refrigerator.

The left part of Fig.4 and Fig. 3 represent embodiments in which the cylinder and the cylinder head cooling each have their own cooling water supply. However, the cooling water flows from both rooms through a single outlet, which is arranged at the opposite ends of the inlets of the cooling chambers. b and c are the leads to your cylinder head coolant. Also in these embodiments, the cooling water flows through the refrigerator in the longitudinal direction. The right part of the design according to Fig. Q. shows examples of the cooling, in which the cooling flow in the cold room is diverted several times.

The fact that in the partition wall between the cooling chambers of a total cooling chamber, the openings for the transfer of the coolant from one Raune zuin other, in contrast to the known devices, according to the invention are located only on the Raumendteil, which is turned away from the one to which the cooling flow in a enters his assigned room or from which he exits after the flow, For example, the cooling flow is forced with its entire amount in turn to each of the combustion chambers located in its assigned space. capture and rinse.

This results in the following advantages. The emergence of so-called. Dead refrigerator parts and the futile long heating of the coolant is prevented. The accumulating amount of heat is distributed over the entire amount of cooling flow and results in only a relatively small coolant heating with the beneficial effects on the machine and the combustion process (avoiding the risk of knocking).

In parallel or V-shaped in-line cylinder engines, the total cooling space between the rows is subdivided either in the longitudinal direction or in the transverse direction by partition walls or partition walls. An embodiment of this type is shown in the Abh. 3. The entire refrigerator is divided by the partition d.
