Definitions
- the invention relates to a cylinder head for a water-cooled internal combustion engine according to the preamble of claim 1.
- DE-A 32 08 341 discloses a cylinder head in which the gas exchange inlet and outlet ducts are arranged according to the direct current principle, ie both ducts open into a common wall that laterally delimits the cylinder head.
- Such direct current heads offer advantages over so-called cross current heads in terms of the space required, since all the components used for supplying the mixture and exhaust gas are arranged on one side of the internal combustion engine.
- the invention has for its object to design a generic cylinder head in such a way that improved cooling is achieved with a cylinder head that can be produced in a simple manner.
- the almost diagonally running deck together with the collecting duct allows cross-flow cooling of each cylinder, which cools the cylinder head evenly and effectively, and a low-resistance outflow of the heated water through the collecting duct.
- the diagonal course of the deck keeps the amount of water in the area of the spark plug inclined to a wall delimiting the cylinder head low and leads the water transversely and quickly to the highly thermally stressed area of the outlet duct.
- the arrangement of the collecting channel in the oil-carrying area enables a straight, low-resistance design of this channel.
- the inlets arranged on the underside of the cylinder head for the cooling water flowing from the crankcase into the cylinder head are dimensioned such that the inlets assigned to the thermally loaded flange side supply approximately 2/3 of the total amount of water.
- the inner boundary wall of the collecting duct has a smooth surface and is connected to the deck, so that the entire oil-carrying area can be formed in one piece upwards when the cylinder head is cast.
- a cylinder head 1 of a water-cooled internal combustion engine has for each cylinder 2 an inlet duct 4 serving for gas exchange in a combustion chamber 3 and an outlet duct 5, both of which open into a flange side 6 which laterally delimits the cylinder head 1.
- a delimiting wall 7 runs parallel to this flange side 6 and a cylinder head upper side 8 and a cylinder head lower side 9 of the cylinder head 1 run at right angles thereto.
- the gas exchange is controlled by a camshaft (not shown) held in bearings 10, which act on cup tappets (not shown) mounted in bores 11 on valves which also slide (not shown) in guides 12.
- Each combustion chamber 3 is assigned an ignition plug (not shown) which is inclined along an axis Z by means of an opening 13.
- a deck 15 is arranged, which extends in the longitudinal direction L within the cylinder head 1.
- the deck 15 separates a water-carrying area W facing the combustion chamber 3 from an oil-carrying area S which receives the valve control.
- the cylinder head underside 9 has inlets 17 and 18, which lead cooling water into the cylinder head 1 from a crankcase of the internal combustion engine, not shown.
- the entrances 17 and 18 are connected to cavities 19 and 20, the cavity 19 washing around the inlet and outlet channels 4 and 5 and opening into the collecting channel 16 at its geodetically highest point via a connection 21.
- the cavity 20 flows around the guide 12 and is connected to the cavity 19 adjacent to the deck 15.
- transverse walls 22 are arranged in the cylinder head 1 between adjacent cylinders 2 and have receptacles 23 for cylinder head screws, lubricating oil bores 24 and openings 25.
- cooling water flows through the entrances 17, 18 into the cavities 19, 20 and through the connection 21 into the collecting duct 16. With respect to each cylinder 2, cross-flow cooling is thus established, which ensures uniform and intensive cooling of the cylinders 2 Areas of the cylinder head 1 causes.
- Inside the collecting duct 16 there is a flow running in the longitudinal direction L, which is via a at the end of the collecting duct 16 arranged discharge opening 26 is fed to a cooling water circuit.
- the flow resistance within the collecting duct 16 is very low, since it is not deflected, e.g. experienced through gas exchange channels. This low resistance causes a rapid flow through the cavities 19, 20 and thus rapid heating of the water in the starting phase of the internal combustion engine and effective cooling in continuous operation.
- connection of an inner boundary wall 27 of the collecting duct 16 to the deck 15 and its smooth-surface design permit simple shaping of the oil-carrying region S when the cylinder head 1 is cast.
- the openings 25 simplify the core bearings during casting, since only a single overall core is thus required, otherwise cores separated from each other by the transverse walls 22 would have to be stored for each cylinder 2.
