Definitions
- the invention relates to a cylinder cover with a cooling channel system for a Reciprocating internal combustion engine according to the preamble of the independent Claim 1, and a reciprocating internal combustion engine with such Cylinder cover.
- the known cylinder cover with a central exhaust valve has a large number of straight floor cooling channels, which are located in the side surface of the Cylinder cover, which essentially defines a conical outer surface of a first (outer) annular space starting from the outlet opening extend, the distance between two adjacent floor cooling channels Outlet opening decreases.
- the floor cooling duct has an entrance and an outlet for a coolant, the inlet of the floor cooling duct is further away from the outlet opening than the outlet.
- everyone Output of a floor cooling duct opens into a valve cooling duct, so that Coolant successively through the floor cooling duct and the valve cooling duct is transportable.
- the valve cooling channels extend in the essentially on a cylinder surface or on a slightly inclined surface Cone surface straight along the outlet opening and open into one common second (upper) annulus from which the coolant can be returned to the cooler of the internal combustion engine.
- the Installation openings for the injection nozzles are concentric on a circular line arranged around the outlet opening between two floor cooling channels. The radius of the circular line is chosen so that for the installation openings enough space between the corresponding floor cooling channels is available.
- the well-known cylinder cover with a central exhaust valve stands out in particular due to the fact that it is highly symmetrical Construction also the thermal loads in operation with the previously short described cooling channel system are particularly easy to control, because the simple geometry of the cylinder cover is of course yours Precipitation is also found in the characteristic of the temperature profile that in the operation of the large diesel engine in the cylinder cover. It means that for example asymmetrical mechanical tension of the Cylinder cover due to complex structured temperature gradients can already be greatly minimized due to the geometry alone. A serious one The disadvantage arises from the fact that the concept of known cylinder cover with a central exhaust valve the use of several Injector calls, which makes this arrangement relatively expensive Additional units must be equipped and therefore quite right overall is expensive.
- EP 0 959 240 Cylinder cover proposed, in which the installation opening for the Injector is located centrally in the top surface of the cylinder cover, see above that only one injector is required for fuel injection.
- the outlet valve is arranged here in the side surface of the cylinder.

- the side surface has an outlet opening for receiving an outlet valve.
- a first annular space in the cylinder cover arranged, which is suitable for the cooling channel system of the cylinder cover Add coolant.
- the cylinder cover according to the invention is characterized by a essentially three-part cooling duct system, which, in Contrary to the known cooling duct system, in addition to a variety of Floor cooling channels and a corresponding number of valve cooling channels, in addition, a certain number of nozzle cooling channels has, which extend along the centrally arranged injection nozzle.
- the floor cooling ducts are on the inlet side with the first Annulus are connected, essentially for cooling the side surface suitable while the valve cooling channels that are located along the outlet opening extend, essentially for cooling the cylinder cover in the area of the exhaust valve and the exhaust valve itself are provided.
- the Nozzle cooling channels extend along the installation opening and are therefore in particular for cooling the injection nozzle and the one at the installation opening adjacent area of the cylinder cover suitable.
- the Nozzle cooling channels open into a common one on the output side Manifold and the valve cooling channels in a common second Annulus, the second annulus by means of a connecting line the manifold is connected.
- the coolant can thus start from the first annular space first flow through the floor cooling channels to cool the side surface, and then in a first sub-cycle through the Valve cooling channels, the second annulus and the connecting line of the Bus line are fed and in parallel in a second Partial circuit fed through the nozzle cooling channels of the manifold which manifold then coolant back to a cooler of the reciprocating internal combustion engine.

- a piston 4 is reciprocated along the axis A - A arranged movably.
- the piston 4 is in by means of a piston rod is known to be connected to a crankshaft (not shown).
- the cylinder cover 1 has one in the ceiling surface 5, essentially centrally arranged installation opening 8 for receiving an injection nozzle 9 on.
- the injector 9 is not connected to a fuel line 91 Injector shown connected to the fuel through the Injector 9 brings into the combustion chamber 7 of the cylinder 3, as the dash-dotted clubs indicate in Fig. 1.
- In the side surface 6 of the Cylinder cover 1 is an outlet opening 10 for receiving a Exhaust valve 11 arranged.
- the cylinder cover 1 is for cooling with an essentially three-part Cooling channel system 2 equipped, which a plurality of floor cooling channels 12 comprises, of which at least two each have an input 13 and one Have outlet 14 for a coolant.

- the outlet opening 20 of the nozzle cooling duct 16 opens into the collecting line 21 shown in cross section, which is connected to a connecting line 22, the function of which later is still described in detail.
- FIGS. 3 and 4 is schematically one embodiment of each Cooling channel system 2 of a cylinder cover 1 according to the invention with Exhaust valve 11 and injector 9 in a representation not to scale outlined. For the sake of clarity, the injector 9 is not installed State shown. As can be seen from FIGS. 3 and 4, extend the floor cooling channels 12, which are generally different in length all, substantially rectilinear, towards the outlet opening 10 of the Cylinder cover 1.
- the floor cooling channels 12 in the cylinder cover are preferred 1 arranged so that their longitudinal axes L - L are in a Conical surface, starting from a first annular space 17 to the axis A - A extend to the center of the cylinder cover 1, the angle ⁇ between the longitudinal axes L - L of any two adjacent floor cooling channels 12 is essentially always the same.
- the angle ⁇ between different pairs of longitudinal axes L - L is different.
- the first annular space 17 is located inside the cylinder cover 1 Arranged periphery and is connected to a via a feed device 171 Cooling device of the cylinder 3, not shown, through which Supply device 171 to the first annular space 17 coolant from the (not shown) cooling device of the cylinder 3 can be fed.
