Definitions
- the invention relates to a gas exchange valve arrangement for internal combustion engines, in particular two-stroke large diesel engines.
- a gas exchange valve arrangement is known from SU 1 768 770 A1, in which a circumferential groove is provided in the region of the cone surface of the valve plate, which is delimited laterally by circumferential, raised projections.
- the groove is to be created by plastic material deformation using a press-on tool with a semicircular profile, which allows only a small depth.
- the groove accordingly has a depth of only about 0.1 mm and therefore proves to be comparatively shallow.
- the groove pressed into the conical surface of the valve disk is intended to absorb the combustion residues. However, due to the shallow groove depth, there is a risk that the residues in the groove will be compacted and this will therefore be filled up in a comparatively short time.
- a gas exchange valve arrangement for internal combustion engines in particular two-stroke large diesel engines, with a stationary valve seat encompassing an assigned flow channel and a valve part that is movable relative to it, which has a valve plate that can be brought into sealing contact with the valve seat, is proposed, with at least one of the mutual conical surfaces of the valve seat or valve disk at least one annular circumferential, narrow sealing surface is provided, which is delimited at least on one side by an annular circumferential material recess.
- each gap formed by a material recess according to the invention can act as a chamber for receiving air, which does not participate in the combustion and accordingly can additionally cool the valve seat.
- the combination according to the invention can therefore be expected to have a long service life for the valve arrangement overall.
- a further advantageous measure may consist in that at least the valve seat is provided with at least one annular, narrow sealing surface. This simplifies production, since the valve seat, which is made of hardened steel, can be machined comparatively easily before hardening. This also ensures that the conical surface of the valve disk can be easily reground if necessary, without changing the depth of the recesses delimiting the narrow sealing surfaces. This also results in simple valve maintenance.
- each narrow sealing surface can have sharp side edges. This results in a particularly good one Shredding of combustion residues reaching the side edges.
- the total width of all sealing surfaces of part of the valve arrangement can advantageously be 0.5% to 2%, preferably 1% to 1.5%, of the mean diameter of the cone surface assigned in each case. This results in a very small width of the sealing surfaces according to the invention, which leads to a particularly low heat transfer and to a particularly good comminution of combustion residues. With a width of the individual sealing surface of 2 mm, very good results were achieved in tests.
- the depth of the recesses delimiting a sealing surface is advantageously greater than the expected thickness of the combustion residues. This ensures that the combustion residues are not pressed into the recesses mentioned and compressed in them and do not fill them up, but that the combustion residues are reliably comminuted and can escape. At the same time, this results in a comparatively large capacity of the recesses mentioned, so that there is a lot of air not participating in the combustion for cooling the valve seat. In tests carried out with large two-stroke diesel engines, good results were achieved with a recess depth of more than 1 mm, preferably up to 3 mm.
- a particularly preferred measure can consist in that the first, narrow sealing surface seen from the combustion chamber is delimited on the side facing the combustion chamber by a material recess which is connected to the combustion chamber by a narrow gap when the valve arrangement is closed, and preferably one opposite a downstream one Material recess has a comparatively large capacity.
- the air taken in does not take part in the combustion and causes good cooling of the valve seat.
- the gap results in an air movement in the through the relevant, comparatively large material recess formed chamber, which improves the cooling effect and causes reliable flushing of the conical surfaces, so that no accumulation of combustion residues can occur, which were previously crushed by the edges of the adjacent, narrow sealing surface.
- the advantages of the overriding measures are further enhanced.
- the angle of inclination of the mutual conical surfaces of the valve seat and valve plate can be different, preferably differ from one another by 0.5 °. This results in particularly narrow mutual contact surfaces and thus a particularly low mutual heat transfer and very good comminution of the combustion residues.
- FIG. 1 shows a gas exchange valve arrangement according to the invention partly in
- Section and Figure 2 shows a detail of Figure 1 in enlarged compared to this
- the field of application of the invention is internal combustion engines provided with gas exchange valves, preferably two-stroke large diesel engines, which have a large exhaust valve arranged in the cylinder head.
- gas exchange valves preferably two-stroke large diesel engines, which have a large exhaust valve arranged in the cylinder head.
- the basic structure and the mode of operation of such motors are known per se and need no further explanation in the present context.
- the gas exchange valve arrangement on which FIG. 1 is based which can be an exhaust valve arrangement of the type mentioned above, contains a cylinder component associated with a stationary component 1, in the example mentioned a two-stroke large diesel engine, at the input of an associated gas channel 2, in the example mentioned on Entrance of the exhaust gas duct, arranged, encompassing this valve seat 3 and a valve part 4 which is movable relative to it and which has a valve plate 6 arranged at the lower end of a shaft 5 cooperating with an actuating device (not shown here), which can be brought into sealing contact with the valve seat 3.
- the valve seat 3 and the valve plate 6 are provided with mutually facing conical surfaces 7 and 8, which can be partially brought into sealing contact.
- the valve seat 3 is here molded onto a seat part 9 inserted into the associated, stationary component 1, in the example mentioned in the cylinder head.
- This consists of hardened steel.
- the seat part 9 containing the valve seat 3 is cooled by cooling channels, not shown here, which are arranged in the component 1 and can be acted upon with coolant, so that the hardness of the hardened steel is retained.
- the movable valve part 4 can consist entirely or at least in the region of the valve plate 6 of a high-temperature-resistant material that does not require cooling. The valve disk 6 therefore assumes a higher temperature in operation than the valve seat 3.
- the conical surfaces 7, 8 of valve seat 3 and valve plate 6 do not come into abutment over their entire width, but only in the area of at least one comparatively narrow, annular circumferential sealing surface 10.
- two such spaced apart axially are within the Upper and lower edge edges of the associated conical surface 7 and 8 arranged sealing surfaces 10 are provided.
- These are delimited at least on one side by annular material recesses 11 and 11a, which are produced by machining, and which practically form annular chambers.
- Crosspieces 12 are formed by the material recesses 11, 11a, the upper side of which each forms a sealing surface 10.
- the cross section of the webs 12 is expediently tapered toward the respective sealing surface 10.
- the sealing surfaces 10 are designed as ground surfaces, so that an exact support on a cooperating, also ground counter surface is ensured. A rougher surface can be provided in the area of the material recesses 11, 11a.
- the material recesses 11, 11a form comparatively large chambers in which no combustion residues can remain. These fall out of the above-mentioned chambers and can therefore escape with the exhaust gas, so that there is no fear of indentations.
- the narrow sealing surfaces 10 cause the combustion residues coming into their area to be dismembered, which facilitates their escape. The formation of indentations and passages, which form the starting point for blow-through holes, is thus effectively prevented.
- there are comparatively small contact areas between the comparatively hot valve plate 6 and the valve seat 7 to be kept at a lower temperature.
- the chambers formed by the comparatively deep recesses 11 can also absorb a comparatively large amount of air which does not participate in the combustion and which accordingly results in a further cooling effect.
- the profiling with material recesses 11, 11a and webs 12 forming the sealing surfaces 10 can be provided in the region of the cone surface 8 of the valve plate or in the region of the cone surfaces 7, 8 of the valve seat and valve plate.
- the sealing surfaces 10 are only in the area of Conical surface 7 of the valve seat 3 is provided.
- the material recesses 11, 11a can advantageously be produced before the seat part 9 is hardened. After hardening, the sealing surfaces 10 can be ground.
- the conical surface 8 of the valve plate 6 is also designed as a ground surface, which is reground from time to time. This is easily possible here without changing the profile depth of the material recesses 11, 11a.
- the width b of the annular circumferential, narrow sealing surfaces 10 is selected such that the total width of all of these sealing surfaces 10 of part of the valve arrangement, here of the valve seat 3, is dimensioned such that the total width of all sealing surfaces 10 of a conical surface 7 or 8 is 0, 5% to 2%, preferably 1% to 1.5%, of the average diameter of the cone surface 7 or 8 in question.
- the number of sealing surfaces 10 present can expediently be chosen such that a width b of the individual sealing surface 10 of at most 2 mm results. This allowed good results to be achieved in experiments.
- the depth t of the material recesses 11, 11a that laterally delimit the sealing surfaces 10 is to be selected greater than the expected thickness of the combustion residues. In most cases, a lower limit is 0.4 to 0.5 mm. However, the depth t can expediently be at least 1 mm, preferably more than 1 mm. In tests with large two-stroke diesel engines, good results were achieved with a depth of up to 3 mm. In the example shown, the depth t corresponds approximately to the width b of the material recess 11 provided between the two sealing surfaces 10, that is to say the material recess 11 arranged downstream of the sealing surface 10 near the combustion chamber. In simple cases, all material recesses 11, 11a assigned to the sealing surfaces 10 can be of the same depth.
- the material recess 11a delimiting the first sealing surface 10 as seen from the combustion chamber i.e. the material recess 11a upstream of the first sealing surface 10
- the material recess 11a upstream of the first sealing surface 10 is accordingly deeper and accordingly also more voluminous than the material recess 11 downstream of the first sealing surface 10.
- the cross-sectional area of the material recess 11a is The example shown is about five times the cross-sectional area of the material recess 1. This also results in a comparatively large capacity for the material recess 11a. When the valve arrangement is closed, this is connected to the adjacent combustion chamber by a narrow gap 14. The gap 14 is so narrow that the air contained in the material recess 11a does not participate in the combustion.
- the combustion pressure leads to air movement in the material recess and thus to a good cooling of the surrounding material of the seat part 9 expediently containing the material recess 11a and at the same time to a good flushing of the conical surface 8 of the valve plate 6 with unburned air.
- the angle of inclination ⁇ of the conical surfaces 7, 8 with respect to the valve axis a can be selected according to the needs of the individual case, for example in a range from 30 ° to 75 °. A range of 45 ° -60 ° is preferred. A small angle x results in comparatively steep conical surfaces 7,8 and thus high contact forces. The lower area can therefore be advantageous in this case.
- the conical surfaces 7, 8 can expediently differ from one another in terms of angle by approximately 0.5 °, the angle ⁇ of the conical surface 7 on the valve seat side being larger by 0.5 ° than the angle ⁇ of the conical surface 8 on the valve plate, which results in a gap opening radially outwards , This measure can improve the knife effect mentioned above.
