Definitions

  • the present invention relates to an internal combustion engine.
  • the present invention also relates to a motor vehicle equipped with a combustion engine with a water/air heat exchanger at the intake
  • the present invention relates more particularly to fixing a casing at an angle to a heat engine wall, in particular a wall of a heat engine cylinder head.
  • a motor vehicle is experiencing more and more constraints to reduce the size of its equipment for reasons of aesthetics or passenger comfort.
  • the vehicle equipped with a thermal engine also called an internal combustion engine, comprises an engine compartment in which is housed a powertrain comprising the engine and its elements or accessories, the dimensions of which are increasingly reduced, resulting in research into improvements in terms of compactness of the engine and its elements or accessories.
  • a heat engine comprises, in known manner, a cylinder block on which a cylinder head is mounted.
  • a cylinder head In said cylinder head are dug air intake ducts which lead to the cylinders.
  • the cylinder head has a face called “intake” against which is fixed an intake distributor capable of directing air or intake gases towards the intake ducts hollowed out in the cylinder head and connected with the cylinders, and a face called “exhaust” against which is fixed an exhaust manifold to recover the burnt gases resulting from the combustion in the cylinders of the engine.
  • the air and/or the intake gases are directed towards the intake manifold having been compressed beforehand by the passage of a compressor which is for example the compression stage of a turbocharger.
  • a cooler stage is installed in the air intake circuit upstream of the cylinder head according to the direction of circulation of the intake air.
  • This cooler stage comprises, for example, an air/water exchanger through which the hot compressed air gives up part of its heat to water or to a cooling liquid.
  • the heat exchanger is housed in a casing which is extended downstream by a fixing flange in the direction of circulation of the intake air, forming a chamber with for example a recess in the cylinder head. Said chamber is part of an intake manifold plenum.
  • crankcase is fixed against the intake face of the cylinder head thanks to the flange.
  • the fixing of this casing must respond to strong mechanical constraints which require parts of great rigidity in metallic material such as steel or steel alloy.
  • said casing is fixed in an oblique direction with respect to the intake face of the cylinder head.
  • Said intake face extends substantially along a vertical plane.
  • the publication DE102014217314-A1 discloses a fixing of a housing against an intake face of a cylinder head of a heat engine, said fixing comprises two support walls substantially orthogonal to each other which are fixed in abutment against two orthogonal surfaces of the cylinder head .
  • a problem with this attachment is the need for two orthogonal bearing surfaces at an upper end of the cylinder head, which can lead to an extra thickness of said upper end of the cylinder head.
  • Another problem is that the fixing is part of the heat exchanger casing which leads to an increase in engine weight.
  • This fixing requires an arrangement close to the upper end of the yoke, a second support surface on the yoke perpendicular to a first support or fixing surface which is parallel to the fixing sidewalk or to the inlet face of the cylinder head.
  • the object of the invention is to remedy these problems and one of the objects of the invention is an arrangement for fixing at an angle a flange for fixing a casing of an engine element to a cylinder head.
  • the present invention relates more particularly to an arrangement for fixing at an angle a flange for fixing a casing of a heat engine element to a fixing wall of a cylinder head of said engine, said cylinder head comprising a fixing curb against which is fixed to the support of the fixing flange by means of a fixing device to a cylinder head,
  • said fixing device comprises a guide and fixing insert mounted in abutment against the wall of a notch dug in the cylinder head from the face of the fixing sidewalk.
  • the fixing device comprises a guide insert and fixing mounted bearing against the wall of a notch cut into the cylinder head from the side of the fixing curb.
  • Said fixing device is capable of withstanding the stresses of tightening or fixing the flange against the cylinder head.
  • the notch may be a countersink hollowed out from the face of the cylinder head fixing sidewalk, which makes it possible to precisely fix the positioning of said device, in particular by avoiding the thin zones of the cylinder head wall.
  • the length of the tubular duct of the fixing device is less than the length of the passage channel of the flange to ensure that the flange is maintained under pressure against the cylinder head.
  • top/bottom refer to an orthonormal frame of reference of the motor vehicle, with two horizontal axes in the plane of the vehicle passing for example through the axles of said vehicle, and a vertical axis orthogonal to said plane facing upwards, for example from the engine towards the vehicle's engine hood.
  • the invention proposes an arrangement for fixing an element of a thermal or internal combustion engine of a motor vehicle at an angle to said engine.
  • THE figures 1 and 2 have a cylinder head 15 of a heat engine and in particular an intake face 14 of said cylinder head 15.
  • an inlet distributor is mounted against the cylinder head to cover the inlet mouth of the cylinder head.
  • Said intake distributor is formed by a fixing flange 19 which allows the fixing of a casing 42 of an element or engine accessory to the cylinder head, here said element is a heat exchanger 11 water / air as represented in there figure 4 .
  • the description which follows describes an oblique fixing of the casing 42 of the heat exchanger 11 in particular of the fixing flange 19 of the said casing, thanks to a fixing means, against the face of intake 14 of the cylinder head 15 of the heat engine, that is to say that the axis of flow of the intake air is oblique with respect to the plane of the intake face 14 of the cylinder head;
  • the fixing axis of the fixing means for example a screw, is also oblique with respect to the plane of the intake face 14 of the cylinder head.
  • the angle formed between said fixing axis and the axis orthogonal to the plane of the intake face of the cylinder head is less than 45°, in particular between 20° and 45°.
  • a heat engine of a motor vehicle is associated with an air intake circuit. Said circuit conducts fresh air picked up at the level of the front face of the motor vehicle towards the engine. Air passes through engine components which may include an air filter, intake valve, compression stage which can be the compressor of a turbocharger. The compression of the air can raise its temperature and it is known to add a passage through a heat exchanger generally of the air-water type to reduce the temperature of the intake air before its admission into the engine. The air can also be mixed with recirculated exhaust gases taken from an exhaust circuit, which increases the temperature of the air-recirculated intake gas mixture. Mixing is generally carried out upstream, depending on the direction of air circulation, of the heat exchanger.
  • the intake air brought to a high temperature during compression or by mixing with recirculated gases passes through the heat exchanger 11 of the water/air type known under the English name of "WaterCAC" to reduce its temperature before its injection into the engine according to figure 4 .
  • the heat exchanger is housed in a casing 42 which is fixed against the intake face 14 of the cylinder head 15.
  • the housing 42 of the exchanger 11 is fixed at an angle against said substantially vertical intake face 14 of the engine.
  • the axis of the intake air flow is oblique with respect to the intake face 14 of the cylinder head as shown in the figure 4 .
  • the flow of the intake air takes place in a direction A1 from the outside towards the cylinder head, said direction A1 makes an acute angle with the axis orthogonal to the plane of the intake face 14 of the cylinder head 15, less than 45°, in particular between 20° and 45°.
  • the cylinder head 15 is schematically parallelepipedic in shape with an inlet face 14 flat and vertical.
  • the exchanger housing 42 is thus fixed at an angle against the inlet face 14 and here near the upper end 12 of said inlet face 14 by means of a fixing flange 19.
  • the fixing flange 19 comprises a bearing face 20 facing the inlet face 14 of the cylinder head, and an opposite outer face 21 which is oblique with respect to said bearing face 20.
  • Said bearing face 20 is intended to bear against a fixing sidewalk 30 which has a flat face substantially parallel to the intake face 14 of the cylinder head.
  • the casing 42 is fixed to said outer face 21 of the flange.
  • the flange 19 thus delimits a chamber 18 which is part of an intake plenum of the engine intake distributor.
  • the fixing flange 19 is attached to the exchanger casing 42 for example by clipping.
  • the fixing flange 19 is fixed against the cylinder head by means of fixing means such as screws, arranged at the edge of the support face of the flange.
  • the fixing axes for said fixing means at the upper end of the flange 19 are at an angle with respect to the bearing face 20, and orthogonal to the said bearing face 20 at the edges sides and at the lower end.
  • the fixing flange 19 is made of a light material which may be plastic.
  • the plastic does not have sufficient rigidity to guarantee the fixing at an angle of the flange 19 with the exchanger casing, against the cylinder head 15.
  • the invention proposes a mounting arrangement 10 of the mounting flange 19, in the upper part of said flange, and of the yoke 15 as shown in figure 1 And 3 .
  • the fixing of the flange to the cylinder head is carried out by means of a fixing device which comprises fixing means such as screws, the axis of which is at an angle with respect to an axis orthogonal to the plane of the intake face 14 of the cylinder head 15.
  • an oblique binding on a vertical support face here the intake face 14 introduces a mechanical stress along the axis of the binding.
  • Said stress is composed of a stress along an axis orthogonal to the bearing face 20 and of a stress parallel to said bearing face which can lead to deformations of the parts. It is necessary to have a device for stiffening the attachment of the flange 19 to the cylinder head.
  • the yoke 15 comprises at least one notch 100, preferably two notches as shown in picture 2 , which are dug from the side of the fixing sidewalk 30. Said notches 100 can be countersinks.
  • the notch 100 has a bearing section 101 which may be rectangular in the bottom of the notch, stretching along the longitudinal axis X of the yoke 15, and a depth of the order of 2 to 5mm.
