Definitions
- the present invention relates to an exhaust device for an internal combustion engine and its production method.
- the present invention relates more particularly to an exhaust duct having a housing suitable for mounting a measurement probe and the method of producing such a housing.
- the internal combustion engines equipping motor vehicles are today provided with an electronic control system which adjusts, from preprogrammed strategies and according to the operating conditions of the engine, the quantity of fuel injected, the quantity of gas recirculated exhaust, etc.
- the measurement probes fitted to the exhaust line are screwed into threaded housings passing through the wall of the exhaust ducts, so as to bring the analysis cells in contact with the exhaust gas flow.
- the tapped holes are conventionally formed by rings which are added by welding into openings made through the exhaust ducts (SEFG welding or resistance welding).
- the present invention therefore relates to an exhaust duct having a tapped hole for housing a probe used for the analysis of the composition of the gases, this hole being produced directly through the same wall of the duct without a welded attached threaded ring.
- the exhaust device for an internal combustion engine according to the invention comprises a duct element inside which the exhaust gases flow, this duct element comprising a housing allowing the mounting of a measurement sensor such as an oxygen sensor.
- the exhaust device is characterized in that the housing intended for mounting the probe is formed by a hole extended by a socket made directly through the wall of the duct element.
- the duct element where the hole extended by a socket is formed has a wall of substantially uniform thickness between 1 and 3 mm.
- the duct element where the hole extended by a socket is formed is made of stainless metal alloy.
- the present invention also relates to a method of producing such a housing.
- the housing produced through the same wall of the duct element is obtained from a first drilling operation consisting in drilling through the wall with a tool, a speed and a penetration force adapted to cause the fusion and the repression of the material around the tool as the advancement of this the latter until a socket of required height and diameter is obtained.
- the tool used for the flow drilling operation consists of an ogival mandrel.
- the first flow drilling operation is then followed by a second tapping operation by deformation.
- Figure 1 is a partial axial sectional view of an exhaust duct according to the invention equipped with a measurement probe
- FIGS 2 and 3 are detail views of the conduit according to Figure 1, detailing the method of producing the housing of the probe.
- an exhaust duct element referenced 1 fitted to an exhaust line of an internal combustion engine mounted for example on a motor vehicle.
- This conduit which is formed by a simple tube of stainless metal alloy of small thickness (conventional steel or steel coated with aluminum), between 1 and 3 mm, and which is intended, for example, to extend into the collector exhaust and catalytic converter not shown, is provided with a housing 2 for a measurement probe 3 such as a lambda oxygen probe.
- the housing 2 is produced directly through the same wall of the tube, using the process described in accordance with Figures 2 and 3.
- the first operation consists in operating by hole punching a hole 21 extended by a socket 22.
- This hole 21 and this socket 22 are obtained by the perforation of the wall of the tube by a mandrel or ogival punch 4, for example made of tungsten carbide, rotating at high speed, at more than 500 rpm and preferably between 3000 and 5000 rpm, and pressed into the tube with a certain penetration force.
- the contact of the rapidly rotating tip locally causes a sharp rise in temperature which brings the metal to the plastic state.
- the thrust exerted by the punch by the advance system makes it gradually penetrate into the hole thus outlined by pushing the material around it.
- Metal flowing in the direction of advance forms a collar and in the opposite direction a bead.
- a collar 41 located at the upper part of the punch can fold the metal overflowing outside the tube and give it a flat surface facilitating the support and sealing of the probe 3.
- a calibrated hole 21 is thus obtained, extended by a socket 22.
- this socket 22 it is then possible to form a thread allowing the probe 3 to be screwed in.
- this second positioning operation a thread 23 is produced by rolled tapping.
- This tapping operation without chips consists in obtaining the thread by deformation of the material of the sleeve 22.
- a tool 5 having an active surface in the form of a screw is used as a tap.
- the tap operates by rolling by deforming the material of the sleeve, the profile of the thread 23 is then printed by displacement of the material from the bottom of the thread towards the crest.
- the speed of rotation and the penetration force of the tap are adapted to produce the desired resistance of the threads. It is possible to choose a speed of rotation of the tap preferably between 700 and 1500 rpm, this however not being limiting of the present invention.
- the present invention offers the additional advantage of being more economical and simpler to enforce.
- the present invention is not limited to the sole production of a tapped hole for housing an oxygen sensor but can be applied to the production of all tapped holes formed on the exhaust line of a internal combustion engine necessary for the installation of the various sensors or probes required for controlling the engine and / or diagnosing the burned gas treatment means or means by catalytic conversion equipping the exhaust line.
- the present invention also applies to exhaust ducts comprising several concentric walls. In this case, the tapped hole necessary for mounting the sensor is produced by carrying out the flow drilling through the various walls.
