Definitions
- the invention relates to a cylinder head of a Reciprocating internal combustion engine having the features of the preamble of claim 1.
- a cylinder head is a Internal combustion engine with a device for storing a Camshaft and a rocker shaft known. This device is approximately in the middle of the cylinder head on the Stored top and extends from the first to the last cylinder. A cylinder head cover covers the Device and is sealingly attached to the cylinder head. The device is a relatively slim component that only the Toggle axles and the camshaft carries.
- Object of the invention is in contrast, a cylinder head with a device for supporting a shaft and / or axle to provide a gas exchange control, which in itself Stiff, the cylinder head stiffened and easy on Single cylinder heads of a multi-cylinder internal combustion engine too assemble is.
- the cylinder head according to the invention consists of a Cylinder head base in the form of several single cylinder heads, the Cylinder head cover and a device for storing a Camshaft and / or a rocker arm shaft.
- This device is designed as a one-piece frame and is on the Cylinder head lower part stored.
- a seal e.g. a liquid seal, inserted.
- the cylinder head with the frame will go up with completed a cylinder head cover, which also with a Seal provided on the frame is placed.
- the frame is very stiff in itself and stiffened by a screw connection with the Cylinder head base the entire assembly cylinder head.
- a Axle and / or shaft can be pre-assembled separately in the frame which makes the manufacturing process in one Simplified production line.
- the Single cylinder heads from their top through the stiff Frame connected and the entire assembly cylinder head is stiffer.
- Another advantage is the essential easier assembly of a common component, pre-assembled is mounted on the single cylinder heads of a cylinder bank, unlike several individual frames, each one on top a single cylinder head are mounted.
- an axis, stored in the frame above the cylinder head base is designed as rocker arm or rocker shaft.
- the pushrods operated, and with Gas exchange valves in the cylinder head will increase the movement of the cylinder Push rods generally deflected by rocker arms.
- These Rocker arms rotate or tilt on an axis that According to the invention in the frame, on the Cylinder head base is mounted, stored.
- the frame a device for supplying lubricating oil to elements of the Gas exchange control on.
- a device for supplying lubricating oil to elements of the Gas exchange control on.
- prefabricated, cast or Drilled lines or channels in the frame can be on easy Make a lubricating oil supply to all points to be lubricated in Valve train, such as rocker or rocker arm, hydraulic valve clearance compensation elements or hydraulically operated switching elements for influencing the timing of the Will be provided.
- Lube flows within the frame can do that Cylinder head base, both in Blockzylinderkopf- as well with single cylinder head construction, easier and thus be made cheaper because only one oil transfer point must be provided in the framework.
- the frame a device for controlling valves of a motor brake on.
- an engine brake i.e.
- Each cylinder of the internal combustion engine has a valve on, for example, at the end of the compression stroke prematurely opens, so that made in the internal combustion engine Compaction work is blown off unused as hot air and the internal combustion engine and the vehicle are braked.
- One such valve is for example operated directly hydraulically or a mechanical actuation of such a valve hydraulically controlled.
- This required hydraulic Pressure and supply lines are according to the invention in the Frame integrated above the cylinder head base. These Lines or channels are pre-cast or in the Frame incorporated. In an integration of the lines or Channels in the frame simplifies the assembly effort considerably. There is no need for an integrated line Sealing points on cable connections, which are expensive to manufacture and seal.
- a fuel low pressure line in the frame integrated a fuel low pressure line.
- a fuel low pressure line By the Integration of a low-pressure fuel line in the frame the assembly effort is further reduced. Since only one Fuel line must be guided to the cylinder head, and the Distribution to the fuel injectors of the individual cylinders taking place within the framework is not just a lesser one Construction costs necessary, but it is the risk of leakage in the fuel system, especially on line connections, reduced.
- This integrated fuel line can be used both as Fuel supply as well as fuel return or in two copies as fuel supply and return be used.
- the frame Connecting piece for fuel injectors on. Through a directly screwing a fuel injector to the frame An additional fuel line is avoided and the Fuel injector is stiff and without additional holding means connected to the cylinder head. That way, one becomes Assembled and reliable mounting and fuel supply provided for the injector.
- a High pressure line for controlling fuel injection in integrated the frame. If the fuel injector is not from a camshaft via levers and similar transmission elements is pressed, for example, with oil, which is under high pressure is, is driven, it is advantageous this High pressure line for the oil in the frame to integrate a confusion of high-pressure lines during assembly excluded.
- the frame a device for venting the cooling system of Internal combustion engine.
- the Internal combustion engine with single cylinder heads is a frame above the single cylinder heads with a Venting particularly advantageous because Single cylinder heads not leading through all cylinders have continuous water cores. That's why everyone has to Single cylinder head at its geodetically highest point one Possibility of venting the coolant system, i. Connections with lines, for example, to a Coolant expansion tank.
- a version with a Frame which covers all cylinders, it is beneficial in each Single Cylinder Head a transfer point for the coolant in to provide a coolant channel in the frame.
- the storage designed as push-through bearing.
- the bearing of the rocker shaft or the camshaft as Through hole the frame retains its rigidity and the Lagergasse is easy to manufacture.
- Bearing cap would lose the frame to stiffness and the Warehouse lane would be more complex in the manufacture and installation of Axis.
- Fig. 1 is a perspective view of a Inventive frame 1 for the storage of rocker shaft axes a plurality of single cylinder heads not shown a multi-cylinder piston engine shown.
- the frame 1 covers several individual cylinder heads, not shown, on the he is screwed to the screw eyes 2.
- the frame 1 for better Representation is the frame 1 at a level 3 between two Drawn cylinders cut.
- the illustrated in Fig. 1 Section of the frame is three cylinder heads of the Hubkolbenmotors assigned and accordingly in three frame parts A, B, C structured.
- the frame 1 comprises two longitudinal outer walls 4 ', 4 ", the each at a level 3 between two cylinders Transverse webs 5 are connected. At these crossbars are the Screw eyes 2 and the bearings 6 for the only about their center axes M indicated toggle axes arranged.
- the center axes M of the rocker arm shafts, not shown extend within the frame 1 over its entire length.
- the frame 1 also has a bottom 7 which forms the frame additionally stiffened and partially interrupted to Passages 8 for not shown elements of the valve control such as plunger, rocker arms and valves allow.
- the bottom 7 is on the top of the not shown Cylinder head up and out through one Liquid seal or a molded seal between the ground and Cylinder head are arranged, sealed.
- the lubrication points of the valve gear, not shown are supplied via a lubricating oil line 12 in the transverse webs 5.
- the Not shown cylinder head cover On the upper end surface 14 of the frame is the Not shown cylinder head cover on, with a seal between the cylinder head cover and frame leakage to the environment prevented to the outside.
- FIG. 2 the frame 1 of FIG. 1 in perspective Representation in a partially assembled version with rocker shaft axes 16 and rocker arms 17 are shown.
- a frame 1 will separately pre-assembled and as a complete unit under Attachment of a seal mounted on the cylinder head.
- Fuel injectors screwed to the connection piece 10 and a cylinder head cover not shown on the End surface 14 attached.
