Brennkraftmaschine mit innerer verbrennung

The invention concerns an internal-combustion engine with internal burn, with a cylinder block at the K0hlrippen is angeformt, a cylinder head, whereby in the range at least a cylinder arranged in the cylinder block first K0hlkanSle is intended, put on on the cylinder block, with further K0hlkan len in connection, which is arranged in the cylinder head. Luftgek0hlte internal-combustion engines offer for example with the employment for Motorr to that, Karts or such a thing a row yon advantages. On the one hand the simple structure is to be called here, there no K0hlmittelpumpen, external K0hler or such hierfer EN is orderlich. Further the optical appearance of the engine plays a grope role in many traps, since an engine provided with K0hlrippen is tzt as sthetisch sch6n eingesch. Unfavorably with luftgek0hlten engines however the delimitation of the achievement, those is by beschr the inkte M6glichkeit of the W@rmeabfuhr given to Bige W always is and one ungleichm rmeverteilung due to the fact that an internal W is rmeaustausch not as well m6glich as with fl0ssigkeitsgek0hlten internal-combustion engines. Like that for example the front of the cylinders is generally due to the wind substantially better charred than the R0ckseite with Motorr dern. With V-engines also transverse to the Fahrzeugl ngsachse of arranged crankshaft is again the rear cylinder generally thermally disadvantaged. From the WHERE 84/01979 a K0hlsystem is for an internal-combustion engine well-known, with which the K0hlmedium partly evaporates. The condensation takes place in an external K0hler. Also such K0hlsystem is structurally relatively complex. Task of of the available invention is it, these disadvantages to be avoided and an internal-combustion engine to be created to increase with which the advantages specified of the Luftk0hlung the above and with that it remains m6glich is, the obtained achievement due to improved K0hlwirkung. ErfindungsgemaB is reached this by the fact that in the auBeren range of the K0hlrippen W rmetauscher Kan le are intended, which with the first K0hlkan len and which further KOhlkan len a K0hlkreislauf closed within the internal-combustion engine forms. By invention in accordance with 6e the training it is m6glich to plan with very simple structure a FI0ssigkeitsk0hlung whereby in particular an external Ki3hler can be avoided. The appearance yon Motorr dern or other vehicles is chtigt from there in no way by such K0hler beeintr. The invention on the fact that the thermal effectiveness of Kohl ribs with their H6he increases, however starting from a certain border one zus tzliche Erh6hung only more small Beitr ge to the K0hlung to been based essentially supply can. By the invention it is m6glich to include also the Qu6eren of ranges of cler K0hlrippen into the K0hlsystem effectively. One g0nstige L6sung is realised constructionally particularly by the fact that in the lower range of the cylinder block Verbindungsbohrungen are intended, which ilen the W irmetauscher KanQle with the first K0hlkan connect. Including the fact that the W irmetauscher Kan#ile are essentially perpendicularly arranged in the installation position, thereby the Thermosyphonwirkung which circulates the K0hlmedium to IQsst, optimized, becomes. A special advantage of the invention consists of it that can become certified, class the K0hlmedium during extreme load of the internal-combustion engine into the first K0hlkan ilen partly simmers. The Umw is extremely accelerated by simmering lzung the K0hlmediums and thus the K0hlwirkung is improved accordingly. So that the Dr0cke remains when simmering the K0hlmediums within justifiable borders, it can be in particular intended that in the upper range of the cylinder head a Ausgleichsbeh is more lter in-formed, which is trained as it a VOL around reconciliation too gew hrleisten. Particularly favourable training of the available invention is given if the W rmetauscher Kan le in the iu6eren range of the K0hlrippen are arranged. In this way k6nnen the K0hlrippen as W irmetauscherfl chen to the Umgebungslult gi ausgen0tzt become nstig particularly. Particularly a g0nstiger structure becomes by the fact erm6glicht that several W rmetauscher Kan ile are combined into a K0hlregister, which (Jber individual Verbindungs6ffnung with the further K0hlkan len is connected. In this way the number of connections between the cylinder block, which can be sealed, can be minimized uncl the cylinder head. A thermally particularly efficient 6rennkraftmaschine can be achieved, if the cylinder of the Brennkraffcmaschine is surrounded by several K0hlregistern. Thereby it is preferential if the K0hlregister 0ber individual Verbindungsbohrung with the first KiJhlkan ilen is connected. In this way also particularly a g0nstiger of internal WQrmeaugleich can be realised. Without a K0hlmittelpumpe it can be done in particular by the fact that the first K (Jhlkan ile, which forms further KiJhlkan le and the W irmetauscher Kan a le closed K0hlsystem, circulated in that a K0hlmedium freely. RK OO4 873 U1 by escape mechanically mobile Bauteiie a particularly robust and long-lived L6sung one reaches. In the consequence the invention is utert on the basis in the figures represented Ausf0hrungsbeispiels more nether erl. The Fig shows. 1 a L ngsschnitt by one invention in accordance with fuel element internal-combustion engine and the Fig. 2 an opinion of the cylinder block of the internal-combustion engine yon Fig. 1 yon down. The internal-combustion engine in accordance with i6 Fig. 1 and Fig. 2 consists of an engine mount 1, a cylinder block 2 and a cylinder head fastened on it 3rd in the engine mount 1 is arranged a crankshaft 4, the waiters a piston rod 5 with a piston 6 in connection stands, which is back and forth mobile in a cylinder 7 along the cylinder axle 8. The cylinder 7 is yon first KOhlkan len 9 surrounded, which extend essentially parallel to the cylinder axle 8 perpendicularly from top to bottom. The first KOhlkan le 9 stands with further Ki3hlkan len in the cylinder head 3 in connection, which chst zun outlined the combustion chamber 11 to follow and then in a connecting section 12 after auBen are gefOhrt. The further KOhlkan le 10 stands within the cylinder head 3 0ber a Verbindungsbohrung 13 with a Ausgleichsbeh more lter 14 in connection, which is partial in the enterprise with K0hlmedium gefi311t. The water level 15 of the Kohl medium is essentially defined by the H6he of a EinfOll6ffnung 16. The connecting sections 12 stand in each case with a Verbindungs6ffnung 17 in the uBeren range of the cylinder block 2 in connection, which directly underneath the cylinder head 3 into a distributor 18 {Jbergeht, from which several W irmetauscherkan le 19 perpendicularly downward gef (3hrt are. Within the lower range of the cylinder block 2 m (Jnden the Warmetauscherkanale 19 in each case into a collecting tank 20, which len waiter a Verbindungsbohrung 21 with the first K hlkan 9 in connection is located. The covers 22 verschlieBen the W rmetauscherkan le 19 downward. The W rmetauscherkan le 19 form altogether four registers 23, which are arranged parallel to the crankshaft axle and/or right-angled to it. The individual W rmetauscherkan le 19 are arranged in Butzen 24 the KQhlrippen 25, whereby the distance D of the individual registers is 23 of the cylinder axle about 70% of the distance D of the edge of the K0hlrippen 25 of that cylinder axle 8. By the available invention it is m6glich to connect in simple way the advantages of air-charred internal-combustion engines with those from flOssigkeitsgekfJhlten internal-combustion engines to.
