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 of an internal combustion engine with a device for supporting a camshaft and a rocker arm shaft is known.
- This device is mounted approximately in the center of the cylinder head on the top thereof and extends from the first to the last cylinder.
- a cylinder head cover covers the device and is sealingly fastened to the cylinder head.
- the device is a relatively slender component that carries only the rocker axles and the camshaft.
- the object of the invention is in contrast to provide a cylinder head with a device for supporting a shaft and / or axle of a gas exchange control available, which is stiff in itself, stiffened the cylinder head and easy to assemble.
- the cylinder head according to the invention consists of a cylinder head lower part, the cylinder head cover and a device for supporting a camshaft and / or a rocker shaft.
- This device is designed as a frame and is mounted on the cylinder head base.
- a seal such as a Liquid seal
- the cylinder head with the frame is closed at the top with a cylinder head cover, which is also fitted with a seal on the frame. Due to the large-scale support of the frame on the cylinder head, the frame itself is very stiff and stiffened by a screw with the cylinder head base, the entire assembly cylinder head.
- An axle and / or shaft can be preassembled separately in the frame, which simplifies the manufacturing process in a production line.
- a plurality of devices for supporting a shaft and / or an axle are formed on adjacent individual cylinder heads as a one-piece frame.
- the single cylinder heads are connected from their upper side by the rigid frame and the entire assembly cylinder head is made stiffer.
- Another advantage is the much simpler installation of a common component, which is mounted on the single cylinder heads of a row of cylinders, as opposed to several individual frames, which are each mounted on a single cylinder head.
- an axle which is mounted in the frame above the cylinder head lower part, designed as a rocker arm or rocker arm shaft.
- the push rods actuated, and with gas exchange valves in the cylinder head the movement of the push rods is generally deflected by rocker arms. These rocker arms rotate or tilt on an axle which according to the invention is mounted in the frame which is mounted on the cylinder head lower part.
- the frame has a device for lubricating oil supply of elements of the gas exchange control.
- a device for lubricating oil supply of elements of the gas exchange control By prefabricated, cast or drilled lines or channels in the frame can be on easy Way a lubricating oil supply all points to be lubricated in the valve train, such as toggle or drag lever, hydraulic valve clearance compensation elements or hydraulically operated switching elements to influence the timing are provided.
- the cylinder head base both in Blockzylinderkopf- and single-cylinder head design, simpler and thus be designed cheaper, since only one oil transfer point must be provided in the frame.
- the frame has a device for controlling valves of an engine brake.
- an engine brake i.
- Each cylinder of the internal combustion engine has a valve that opens prematurely, for example, at the end of the compression stroke, so that the compression work performed in the internal combustion engine is blown off unused as hot air and the internal combustion engine and the vehicle are braked.
- Such a valve is for example operated directly hydraulically or a mechanical actuation of such a valve is controlled hydraulically.
- This required hydraulic pressure and supply lines are integrated according to the invention in the frame above the cylinder head base. These pipes or channels are pre-cast or incorporated into the frame. With an integration of the lines or channels in the frame, the assembly effort is considerably simplified. In the case of an integrated line, there are no sealing points on the line connections, which are complex to manufacture and seal.
- a fuel low pressure line is integrated into the frame.
- a low-pressure fuel line is integrated into the frame.
- the assembly effort is further reduced.
- the Distribution takes place to the fuel injectors of the individual cylinders within the frame, not only a lower construction cost is necessary, but it is the risk of leakage in the fuel system, especially at line connections, reduced.
- This integrated fuel line can be used both as a fuel supply and as a fuel return or in duplicate as Kraftstoffvor- and - Weglauf.
- the frame has connecting pieces for fuel injectors.
- a fuel injector By directly screwing a fuel injector to the frame, an additional fuel line is avoided and the fuel injector is rigid and without additional retaining means connected to the cylinder head. In this way, a mounting and reliable support and fuel supply for the injector is provided.
- a high-pressure line for controlling the fuel injection is integrated into the frame. If the fuel injector is not actuated by a camshaft via levers and similar transmission elements, but is driven, for example, with oil, which is under high pressure, it is advantageous to integrate this high pressure line for the oil in the frame to a confusion of high pressure lines in the Exclude installation.
- the frame has a device for venting the cooling system of the internal combustion engine.
- a frame above the individual cylinder heads with a venting possibility is particularly advantageous because individual cylinder heads do not have leading through all cylinders continuous water core. That's why every single cylinder head has to have one at its geodetically highest point Have possibility for venting the coolant system, ie connections with lines, for example, to a coolant expansion tank.
- the frame Since the frame generally occupies a geodetically higher position than the cylinder head base, therefore, only a venting possibility in the coolant channel is provided in the frame. In this way, the parts and assembly costs for venting of the coolant system in the cylinder head is significantly reduced. At the same time, operational safety is substantially increased due to fewer cables and line connections.
- the bearing of the axle is designed as a push-through bearing.
- the frame retains its rigidity and the storage lane is easy to manufacture.
- the frame would lose rigidity and the bearing lane would be more expensive to manufacture and assemble the axle.
- Fig. 1 is a perspective view of a frame according to the invention for the storage of rocker shafts for a cylinder head according to the invention and also
- Fig. 2 is a perspective view of the frame of Fig. 1 with inserted rocker arms and Kipphebelachsen
- an inventive frame 1 for supporting Kipphebelachsen is shown in a perspective view of a plurality of individual cylinder heads, not shown, a multi-cylinder reciprocating engine.
- the frame 1 covers a plurality of individual cylinder heads, not shown, to which it is screwed to the screw eyes 2.
- the frame 1 is drawn cut on a plane 3 between two cylinders.
- the illustrated in Fig. 1 portion of the frame is assigned to three cylinder heads of the reciprocating engine and divided into three frame parts A, B, C accordingly.
- the frame 1 comprises two longitudinal outer walls 4 ⁇ 4 X1 , which are each connected to a plane 3 between two cylinders by transverse webs 5. At these transverse webs, the screw eyes 2 and the bearings 6 are arranged for the only indicated about their center axes M Kipphebelachsen.
- 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 additionally stiffens and partially interrupts the frame to allow passages 8 for valve control elements, not shown, such as plungers, rocker arms and valves.
- the bottom 7 rests on the top of the cylinder head, not shown, and is sealed to the outside by a liquid seal or a molded seal, which are arranged between the bottom and the cylinder head.
- a longitudinal outer wall 4 x extend over the entire length of a fuel supply channel 9 and a
- Fuel return channel 9 ' are in fluid communication with connecting pieces 10 for fuel injectors, not shown. In this way, assembly of separate fuel lines to each fuel injector is not required, which makes the fuel cycle system simpler, less expensive, easier to assemble, and more economical more reliable to realize.
- the lubrication points of the valve drive are supplied via a lubricating oil line 12 in the transverse webs 5.
- a longitudinal outer wall 4 extends over the entire length of an integrated high pressure oil passage 13, which is used to supply hydraulically assisted, electrically operated fuel injectors with high pressure oil.
- the not-shown cylinder head cover On the upper end surface 14 of the frame, the not-shown cylinder head cover is located, with a seal between the cylinder head cover and frame prevents leakage to the outside environment.
- ⁇ runs over the entire length of the frame, a channel 15 fordetically highest point of the water space of the cylinder head and thus the entire cylinder on each cylinder.
