Definitions
- the invention relates to an internal combustion engine with a crankcase, in which a crankshaft is rotatably mounted, on which at least one connecting rod is articulated, which carries a piston which is operated in a gas exchange valve inserted by a cylinder head and actuated by a camshaft via bumpers and rocker arms covered cylinder tube is movable, that a cylinder housing can be inserted into the crankcase and clamped with a collar between the cylinder head and the intermediate housing, the intermediate housing having a region widened on one side, which forms a covering of the bumpers over the height of the intermediate housing.
- the invention has for its object to provide an internal combustion engine with an intermediate housing, which is improved over the prior art.
- this object is achieved in that the expanded region has a support surface for an injection pump element that surrounds a bushing.
- all functional parts belonging to a cylinder unit can be integrated directly into the intermediate housing.
- the injection system can thus be improved in particular in such a way that shorter injection lines to the associated injection valve can be implemented.
- a more rigid injection system is created with the improvements in terms of injection, consumption, exhaust gas emission and noise emission that can be achieved accordingly.
- a direct spatial assignment of the components to a cylinder unit means that parts can be replaced more quickly in the event of maintenance and repairs, since, for example, a complete cylinder unit with cylinder head, intermediate housing, cylinder barrel, piston and connecting rod as well as the complete injection system and the valve actuation mechanism are replaced can be.
- the preassembly can go so far that the valve clearance and the start of delivery have already been set in the cylinder unit to be replaced.
- the expanded area has guides for roller tappets.
- These are the guides for the roller tappets of the bumpers and / or the injection pump element, wherein guides for all roller tappets are advantageously present.
- This design has the advantage that when a cylinder unit is attached, it is not necessary to ensure that the roller tappets are inserted precisely into corresponding guides which are embedded in the crankcase. Rather, the preassembled assembly unit forms an integral system that can be preassembled with all components and in which the functionality of the individual components can be checked.
- the guides are oriented inclined to the cylinder longitudinal axis.
- the inclination is oriented towards the cylinder head.
- This design has the advantage that the valve actuation axis from the camshaft to the rocker arms in the cylinder head with simultaneous adjustment of the Offset between the camshaft and the rocker arm ends is straight.
- the injection pump element is also inclined at an angle that is at least similar to the cylinder head. As a result, the distance between the high pressure outlet of the injection pump element and an injection valve connection, in particular laterally leading out of the cylinder head, is very short. This contributes to further stiffening of the injection system.
- a main oil channel is led through the intermediate housing from the crankcase side to the cylinder head side.
- This main oil channel begins in a camshaft bearing location of the camshaft in the crankcase and leads oil to the valve train in the cylinder head. This training contributes to an integral system of a cylinder unit.
- a leak fuel channel is led through the intermediate housing from the cylinder head side to a fuel line connection which opens into the recess for the injection pump element.
- This leakage fuel ka na I can be continued in the cylinder head in further leakage fuel lines which lead directly to the injection valve and discharge the leakage fuel from it.
- the fuel line connection is then, in particular, a central leakage fuel return duct, into which the fuel that is diverted by the individual injection pump elements is also introduced.
- the individual leakage fuel return channels in the individual intermediate housings lying next to one another are then connected to one another by corresponding connecting lines.
- a cooling liquid transfer opening is let into the bottom of the intermediate housing in the longitudinal axis of the internal combustion engine next to the cylinder tube opening and opens into the cylinder tube opening above the bottom.
- the coolant enters the intermediate housing next to the cylinder tube opening from the crankcase and reaches the cylinder tube opening within the intermediate housing.
- the cylinder tube inserted into the intermediate housing can be sealed in relation to the bottom region and in the head region of the intermediate housing, so that this seal remains in place, for example, when a complete cylinder unit is removed. Any cooling liquid which may remain in the cooling rooms cannot therefore get into the oil-carrying parts of the internal combustion engine.
- cooling liquid outlet openings are let into the deck of the intermediate housing. These coolant outlet openings are connected to the cylinder opening. Through these coolant outlet openings, the coolant is passed on from the intermediate housing into the cylinder head, and here too the cylinder tube can be sealed off from the intermediate housing by a corresponding structural design, this seal also not having to be removed when the cylinder unit is removed.
- cooling liquid outlet openings are arranged on the periphery of the deck. This configuration enables a fluidically favorable transfer of Coolant from the intermediate housing into the cylinder head so that the cylinder head base plate can be cooled evenly.
- a fuel feed channel is arranged in the intermediate housing and is in flow connection with the recess for the injection pump element.
- This area is of course sealed off from the remaining area of the recess, so that, in particular, there is no short circuit with the area in which the leak fuel is discharged.
- this design enables simplification in that no lines have to be connected to the injection pump element, but only short line pieces are required to connect the individual intermediate housings of a row of cylinders.
- a damping space connected to the fuel inlet channel is embedded in the intermediate housing. This design makes the installation of additional damping elements as external components superfluous.
- the cylinder head, the intermediate housing, the cylinder tube, the piston and the connecting rod form an assembly unit that can be preassembled.
- these components can be assembled elsewhere by fitters who may have been specially trained for the assembly of these components and can be attached to the internal combustion engine as a prefabricated assembly unit.
- the final assembly of the internal combustion engine can be significantly shortened in time, for example in the case of a 16-cylinder V-type internal combustion engine, the 16 cylinder units no longer have to be assembled one after the other on the internal combustion engine, but the 16 cylinder units can be attached as individual assembly units in a time-saving manner.
- the technicians who carry out the final assembly of the internal combustion engine need not be familiar with the assembly instructions for all individual components, so that, for example, Training a fitter can be done faster and is therefore less expensive.
- a defective cylinder unit can be replaced as an assembly unit more quickly than if the individual components had to be dismantled individually and then the new parts had to be installed again. This significantly reduces the downtime of the internal combustion engine.
- the cylinder head can be screwed to the intermediate housing by means of mounting screws, and the cylinder tube is clamped between the cylinder head and the cylinder tube via an annular flange.
- an assembly unit is created with simple means, which can be preassembled on components without significant additional expenditure.
- four mounting screws are provided, which are distributed on the circumference of the cylinder unit for screwing the intermediate housing to the cylinder head. These mounting screws do not need to be dismantled even after the assembly unit has been installed, although this can be provided in individual cases.
- the piston and the connecting rod can be fixed in a predetermined position in the cylinder tube with a holding device. While in the case of smaller internal combustion engines the piston with the attached connecting rod may only need to be pushed into the cylinder tube during the pre-assembly and remains in the cylinder tube due to the preloading of the piston rings, in particular in the case of medium-sized and larger internal combustion engines, the piston and connecting rod are fixed necessary and sensible. This fixation serves, on the one hand, to ensure that the piston with the attached connecting rod cannot accidentally slide out of the cylinder tube due to its weight and, moreover, has a precisely defined assembly position during assembly of the assembly unit.
- the holding device prevents the connecting rod from moving uncontrollably about this pivot axis during transport, for example due to its articulated articulation on the piston, and can thus lead to damage.
- the holding device is a holding element which can be fastened to the lower end of the cylinder tube and which pushes the piston into its TDC position and is also a clamping element that fixes the connecting rod at least approximately centrally in relation to the longitudinal plane of the cylinder tube.
- the design of the holding device as a holding element and clamping element enables simple and precise loading and precise fixing of the piston and connecting rod in a precisely predeterminable position.
- the holding element and the clamping element can be made of a resilient material. The holding element and the clamping element can be combined to form a component and, after the assembly unit has been installed, can be removed through an assembly opening in the crankcase.
- the holding device is a mounting bracket which can be screwed to the lower end of the cylinder tube and to a connecting rod bearing cap thread of the connecting rod.
- This design enables the piston and the connecting rod to be fixed very precisely.
- the fact that the mounting bracket is fastened to a connecting rod bearing cover bore prevents the mounting bracket from being “forgotten” after the mounting unit has been installed, since the mounting bracket must be removed in order to mount the connecting rod bearing cover.
- the assembly unit includes all associated components, such as injection valve, injection pump element, injection line, bumpers, roller tappets, etc.
- the components such as bumpers and roller tappets, are held in such a way that they are retained cannot move the assembly unit during transport and assembly, and in particular cannot be lost.
- these can be dimensioned so precisely that the start of delivery and / or the valve clearance of the gas exchange valves on an assembly device can be adjusted during the pre-assembly.
- FIG. 1 a top view of the deck of the intermediate housing
- FIG. 2 a section AA according to FIG. 1 through the intermediate housing
- FIG. 3 a section BB according to FIG. 1 through the intermediate housing
- FIG. 4 an assembly unit including the intermediate housing ⁇ house.
- the intermediate housing 1 has a cylinder tube opening 2 through which a cylinder tube is pushed.
- the cylinder tube then lies with a circumferential collar on the deck 3 of the intermediate housing 1 facing the cylinder head and is held in this position by the cylinder head.
- the cylinder tube in the area of the deck 3 and the bottom 4 of the intermediate housing 1 is sealed with respect to the latter.
- the cylinder tube opening 2 is formed such that an annular space is formed between the intermediate housing 1 and the cylinder tube used, through which cooling liquid flows.
- This coolant passes through a coolant transfer opening 5 let into the bottom 4 from the crankcase into the intermediate housing 1.
- the coolant transfer opening 5 has connections 6 (FIG. 2, FIG. 3) which connect the coolant transfer opening 5 with the cylinder tube opening 2 in the area between connect the bottom 4 and deck 3.
- the introduced cooling liquid thus flows through the intermediate housing 1 and enters the cylinder head via four cooling liquid outlet openings 7 in the deck 3 of the intermediate housing 1.
- the intermediate housing 1 has an extended area 10 on one side, in which bushings 11 a, 11 b for the bumpers of the valve drive and a bushing 11 c for the injection pump element are let in.
- the injection pump element is fastened with a flange on a support surface 17.
- the bushings 1 1 a, 1 1 b, 11 c form guides 12a, 12b for roller tappets, which actuate the gas exchange valves in the cylinder head via bumpers.
- a guide 12c for the roller tappet of the injection pump element is also inserted into the bushing 11c.
- the bushings 11, 11b, 11c and the guides 12a, 12b, 12c are inclined to the cylinder head with respect to the cylinder longitudinal axis.
- the roller tappet When pre-assembling a cylinder unit, the roller tappet is also pre-assembled for both the injection pump element and the bumpers.
- the roller tappets are secured against inadvertent sliding out of the guide 12a, 12b, 12c. This can be done, for example, by means of a pin engaging in a groove embedded in the roller tappet, or, for example, by means of a circumferential collar on the roller tappet, which, when mounted on a corresponding shoulder in the bushing 1 1 a, 1 1 b, 11 c lies on.
- a main oil channel 14 which connects the deck 3 to the floor 4, is also let into the intermediate housing 1.
- the main oil channel 14 within the intermediate housing 1 has an offset from approximately the center of the intermediate housing 1 to an edge region. This is due to the fact that a bearing point of the camshaft mounted in the crankcase is arranged in the wall area below the intermediate housing 1, from which the oil is guided into the main oil channel 14 by corresponding connections. This oil is then fed through the intermediate housing 1 into the cylinder head, in order then to be distributed into distribution channels in the valve mechanism below a rocker arm bracket.
- a leak fuel channel 15 is let into the intermediate housing 1, the leak fuel channel 15 being guided from the deck 3 into the bushing 11c for the injection pump element. Furthermore, a damper chamber 16, which is connected to a fuel inlet channel, is let into the intermediate housing. In this damper chamber 16, pulsation vibrations of the fuel that is fed to the individual injection pump elements are damped.
- FIG 4 shows a complete assembly unit 101, which is fully pre-assembled and can be placed on the crankcase.
- the assembly unit 101 comprises at most all the components shown in the drawing, but in each case the cylinder head 102, the intermediate housing 103, the cylinder tube 104, the piston 105 and the connecting rod 106 are present.
- the intermediate housing 103 is screwed to the cylinder head 102 by mounting screws.
- the mounting screws are inserted into recesses, not shown, on the outer circumference of the intermediate housing 103 and are screwed into the cylinder head from below through a hole in the intermediate housing. In this way, the intermediate housing 103 is clamped to the cylinder head 102 while simultaneously clamping the cylinder tube 104.
- the cylinder tube 104 has an annular flange 107, under which the intermediate housing 103 engages.
- the connecting rod 106 and the piston 105 can be fixed in a precisely predetermined position by a holding device in the cylinder tube 104.
- the holding device is either a holding element 108 and a clamping element 109 or a mounting bracket 110.
- the holding element 108 which if necessary. can be formed in one piece with the clamping element 109, is fixed by a screw 1 1 1 to the cylinder tube 104 and is designed as a spring element which presses the piston 105 in its TDC position against the cylinder head.
- the connecting rod 106 is pressed into the clamping element and is held by the latter in a predetermined position.
- the mounting bracket 1 10 is provided, which can also be fastened to the cylinder tube 104 by a screw 1 1 1 a. With the other end, the mounting bracket is screwed to a connecting rod bearing cover bore.
- a screw 1 1 1 b is used, which can be screwed into the existing threaded hole for fastening the connecting rod bearing cover.
- the complete assembly unit 101 is placed on the crankcase of the internal combustion engine for assembly, the crankshaft being rotated into a predetermined position during placement or before placement. This position is designed so that the assembly unit 101 can be pushed completely into the crankcase without the connecting rod hitting the corresponding crankshaft journal. After the assembly unit 101 has been inserted in this way, it is screwed to the crankcase via conventional tie rods.
- crankshaft with the associated journal is also screwed into the bearing point of the connecting rod 106 and the connecting rod bearing cover is mounted. If the connecting rod 106 is held by the mounting bracket 110, this must of course be removed beforehand, while conversely the holding element 108 and the clamping element 109 can also be removed after the connecting rod bearing cap has been installed.
- the assembly unit 101 also includes, in addition to the components listed above, an exhaust manifold element 1 12, the complete valve actuation mechanism 1 13 with rocker arm bracket, rocker arm pin, rocker arm, valve bridge element, bumper tube and all adjusting screws.
- the pre-assembly can go so far that the valve clearance is already set during the pre-assembly and the valve cover 1 14 is mounted.
- the complete injection device including the injection pump element 1 15, the roller tappet 1 16, the injection line 1 17, the injection valve 1 18 and a lateral connection pressure piece are also in the exemplary embodiment 119 pre-assembled.
- the start of delivery of the injection pump element 115 can be set during the pre-assembly, so that when the assembly unit 101 is mounted on the crankcase, the roller tappet 116 comes into contact with the camshaft 120 without any adjustment work.
