Definitions
- the invention relates to a piston for an internal combustion engine according to the preamble of claim.
- a piston for an internal combustion engine in whose piston bottom side edge region a closed ring element is arranged, which is connected to the main body of the piston by means of a high temperature resistant adhesive, and its purpose is a hub side arranged for this purpose ring carrier To fix ceramic.
- a ceramic material is chosen here for the purpose of utilizing this material's own thermal insulation effect and to reduce the temperature-induced expansion of the ring carrier, which is in contact with the thermally highly stressed ring element and thus is itself exposed to a very large thermal load.
- this method of avoiding temperature-induced damage to the piston due to excessive thermal load of individual piston parts is very expensive and has the disadvantage of significantly increasing the cost of production of the piston.
- the cooling channel which can be introduced in a simple manner between the piston main body and the ring element, ensures good cooling of both the ring spar tie as well as the thermally very highly loaded edge of the combustion bowl and thus for a high thermal load capacity of the piston according to the invention.
- FIG. 1 shows a piston for an internal combustion engine with a ring element according to the invention in a two-half sectional image showing two offset by 90 ° longitudinal sections of the piston
- Fig. 2 is an enlarged view of the section through the edge region of the piston crown with the ring element.
- FIG. 1 shows a piston 1 for an internal combustion engine in a sectional view consisting of two halves, whose left half represents a section of the piston 1 along a longitudinal axis 2 of a hub bore 3 and the right half of which is offset by 90 ° relative to the piston 1.
- the piston 1 consists of a substantially cylindrical base body 4, one end face of which forms the piston crown 5.
- a closed ring element 6 is arranged in the central region of the piston head 5.
- a combustion bowl 7 is formed in the central region of the piston head 5.
- the base body 4 on its side facing away from the piston bottom 5 pin bosses 8 for the hub bores 3 and the pin bosses 8 interconnecting shaft elements 9.
- the ring member 6 has on its radially outer circumferential surface 10 an annular groove 1 1 for a compression ring, not shown in the figure. Below this, a second annular groove 13 is arranged in the lateral surface 12 of the base body 4, followed by an oil ring groove 14 on the bolt hub side.
- annular, closed cooling channel 15 is arranged, which partly by a molded-in in the base body 4 recess 16 and partly formed by a molded-in in the ring member 6 recess 17.
- cooling oil is in the cooling passage 15 and derived from it again.
- the base body 4 is made of aluminum, wherein initially in the forging process, a blank is produced, which is given by means of a machining production process (turning, milling) the final shape.
- the ring element 6 is produced by casting from Niresist, wherein also first a blank is produced, which is given by means of a machining production process, the mold shown in Fig. 1.
- Nires is an austenitic cast iron mixed with nickel, manganese, copper and chromium as alloy components.
- the ring member 6 is connected to the base body 4 by means of a high temperature resistant adhesive.
- FIG. 2 shows in an enlarged view the piston bottom side edge region of the piston 1 with the ring element 6, with the cooling channel 15 formed by the ring element 6 and the main body 4, and with the ring part 20 partly arranged in the ring element 6 and partly in the main body 4.
