Definitions
- the invention relates to a suction device for a Internal combustion engine according to the preamble of claim 1.
- the suction device includes a housing made of plastic with several Intake pipes coming from a common, as a plenum trained air collector branch and on the combustion air the cylinders of the internal combustion engine is to be supplied.
- the Plastic housing of the suction device is via a mounting flange bolted to the cylinder head of the engine.
- the screw requires a certain assembly effort.
- care must be taken that in the area the attachment points do not cause impermissibly high force peaks, which could lead to a material destruction.
- the invention is based on the problem with simple measures the conditions for a permanent connection between the housing of a suction and the cylinder head create.
- the connection should be easy to assemble and disassemble allow the suction.
- the suction device In the suction device according to the invention are on the plastic mounting flange or plastic housing pairs of clips injection-molded, in which retaining elements positively receivable are, which are supported in mounting position on the cylinder head.
- the holding elements can be inserted into the pairs of clips or be plugged in and become a pair of the two Clasps form-fitting embraced. That way the assembly and disassembly of the suction essential simplified because the mounting flange only on the cylinder head needs to be placed or plugged in and Fittings can basically be omitted or at least the number of glands can be reduced.
- the pairs of clips can be injection molded during manufacture of the mounting flange of the suction device in one piece or be produced in one piece with this.
- each intake pipe is assigned a pair of brackets, wherein the number the intake manifold usually the number of cylinders of the internal combustion engine equivalent. Since a plurality of pairs of clamps provided is, are the holding and in particular the assembly forces between the mounting flange and the cylinder head over the Length of the mounting flange distributed, reducing the risk a material overload is reduced.
- the force application takes place in the area of the pairs of clips and the recorded therein Retaining elements.
- the holding elements which taken in the pairs of clamps and in mounting position on Cylinder head are held, attached to a fuel rail, which is carried out separately from the mounting flange. about the retaining elements will provide an additional connection between the Fuel distributor and the mounting flange created, so that further connections between these two components are eliminated may or may reduce the number of such connections can be.
- Another advantage is to be seen in that the mounting flange in mounting position between the Fuel manifold and the cylinder head are trapped can, with the result that on the mounting flange Overlying fuel rail over its entire length evenly applies a contact pressure on the mounting flange, whereby any force peaks are avoided.
- the fuel distributor is advantageously made of metal and is therefore in able to safely and safely absorb higher forces, the transferred via the holding elements on the fuel rail become.
- the holding elements firmly connected to the fuel rail are, is at an insertion of the retaining elements in this provided pair of clips at the same time a positive connection created between mounting flange and fuel rail.
- the holding elements can be designed as so-called nozzle cups be, which have cup shape and the bottom of the fuel rail facing, wherein in the bottom of a flow-through for fluid communication with the fuel rail is introduced.
- the open side of the nozzle cups is open Fuel nozzles attachable to the cylinder head, allowing the fuel from the high pressure line of the fuel rail over the nozzle cups can be fed to the fuel nozzles.
- the nozzle cups comes in this version, the additional function of Fuel transfer from the high pressure line to the fuel nozzles to.
- the suction device 1 shown in Fig. 1 for the supply combustion air to the cylinders of an internal combustion engine comprises a mounting flange 2 made of plastic with a Plural intake pipes 9, which have an upstream Air distributor housing 3 with a central intake opening. 4 Supply combustion air.
- a fuel distributor 5 is fitted with a high-pressure line, the standing over a feed nozzle 10 under high pressure Fuel is supplied, which on the individual cylinders the internal combustion engine is distributed.
- the feed nozzle 10 is located on a mounting plate 6, which with the High pressure line of the fuel rail 5 is connected, in particular is soldered, and above the top of the fuel rail extends.
- the Number of sockets 11 corresponds to the number of intake pipes 9, which in turn corresponds to the number of cylinders of the internal combustion engine; if necessary, the number of sockets or the Intake pipes also differ from the number of cylinders.
- a pressure sensor 12 via which the fuel pressure in the high pressure line 5 is to measure.
- Fig. 1 in conjunction with the cutout magnification 2 and the sectional view of FIG. 3, are on the mounting flange 2, the number of intake pipes 9 corresponding Clamp pairs 13 molded plastic, in which Nozzle cups 14 are accommodated on the bottom arranged the fuel distributor 5 and, for example by means of Soldering are firmly connected with this.
- the nozzle cups 14 Among others, they have the function of holding elements, which are received positively in the pairs of clamps 13. Since the Fuel distributor 5 with the mounting plate 6 on the mounting flange 2 of the suction rests, thereby also the mounting flange 2 with the underlying Cylinder head connected.
- each Clamp pair 13 two cooperating clamp members 13a and 13b includes, which define a receiving opening into which the nozzle cup 14 is inserted and in the nozzle cup form-fitting is included.
- the nozzle cup 14 is on a fuel nozzle 17 attachable, which is connected to the cylinder head and projects into a cylinder of the internal combustion engine.
- a flow-through opening 16 which with a corresponding Throughflow 15 in the wall of the fuel rail 5 is aligned. The fuel flows over the flow openings 15 and 16 in the fuel nozzle 17 and is about these injected into the cylinder of the internal combustion engine.
- the nozzle cup 14 is appropriate as well as the fuel rail Made of metal and is appropriate to the fuel rail soldered; but there are also other types of connections into consideration. It may also be useful on the fuel nozzle to provide a sealing ring.
