Description of drawings
To be described in detail the mode of combustion engine exhaust component by the reference accompanying drawing now with example, wherein:
Fig. 1 is the side sectional view of a foundation combustion engine exhaust component of the present invention;
Fig. 2 is the sectional view along II-II line among Fig. 1;
Exhaust component partly the amplification view of Fig. 3 for irising out and be instructed in the III place among Fig. 2; And
Exhaust component partly the amplification view of Fig. 4 for irising out and be instructed in the IV place among Fig. 2.
Embodiment
In Fig. 1, the exhaust component 10 of an internal combustion engine exhausts---it is a rear cabinet in particular---comprises a columnar shell 12, and shell 12 has an input end cap 14 and an output end cap 16.Shell 12 and end cap 14,16 define a chamber 18.Dividing plate 20,22 each intervals of two circles are turned up the soil and are arranged in the chamber 18.First dividing plate 20 is provided with towards input end cap 14, and second partition 22 is provided with towards output end cap 16.Thereby, chamber 16 is divided into the first sub-chamber 18a, the second sub-chamber 18b, the 3rd sub-chamber 18c, the described first sub-chamber 18a is defined between the input end cap 14 and first dividing plate 20, the second sub-chamber 18b is defined between first dividing plate 20 and the second partition 22, and the 3rd sub-chamber is defined between second partition 22 and the output end cap 16.Supplying tube 24 extends through a hole 26 that is arranged in input end cap 14, pass one is arranged in the hole 28 of first dividing plate 20 and passes a hole 30 that is arranged in second partition 22.Supplying tube 24 with interference fit by hole 28,30 and ccontaining.Supplying tube 24 has a plurality of perforation 32 that are formed in its wall in the zone of described pipe between first dividing plate 20 and second partition 22.An output tube 34 extends the hole 36,38 by being arranged in first dividing plate 20 and second partition 22 respectively from sub-chamber 18a, and extends through the hole 40 that is arranged in output end cap 16.Output tube 24 is ccontaining by hole 36,38 interference fit ground.Normally, in the time of on being installed in a vehicle, member 10 is arranged so that supplying tube 24 is positioned at the top of output tube 34.
Dividing plate 20,22 respectively has one and is formed at the mouth (port) 42,44 that its outer edge is positioned at output tube 34 belows respectively.
Then observe Fig. 2, condensation product can gather in the rear cabinet of internal combustion engine exhausts.Fig. 2 shows condensation product at label 46 places.As mentioned above, known ground uses the condensation product device for transferring that condensation product is discharged from rear cabinet.The condensation product device for transferring only allowed a certain amount of condensation product and rests in the rear cabinet before condensation product is discharged from.Therefore, for each such member, the maximum height of condensation product 46 is known.In Fig. 2, the maximum height of condensation product is indicated with depth D.Certainly, when exhaust component 10 was arranged on the vehicle, it can be subjected to the effect of accelerating force, for example because the vibration of vent systems or because the motion of the vehicle that links to each other with vent systems.This can cause condensation product to have some to move in exhaust component 10, and, by exhaust component is carried out suitable test---for example by vibration-testing and the road test by example system on the car, can calculate the maximum mobile degree of the condensation product 46 of each member.The maximum mobile degree that indicates condensation product in Fig. 2 is between radial line A and B.Therefore, the zone of shell 12 internal surfaces between line A and B will be subjected to further corroding owing to contacting with condensation product.In the present invention, in the zone between online A and the B, a lining 48 is applied on the internal surface of shell 12.In Fig. 3, more be shown clearly in this lining.
Usually, shell 12 is made by DIN 1.4512, and thickness is 0.8mm; The lining 48 on the zone will comprise that thickness is the DIN 1.4113 of 0.5mm between line A and line B and be applied to.Certainly, those skilled in that art can select other material and/or material thickness according to the relevant environment of specific member and this member.
Lining 48 is applied on the relevant surfaces of shell 12 by spot welding.Usually, lining is to be applied on this shell when shell becomes a flat board to be provided with, and then, this shell is subsequently around dividing plate 28,30 bendings, and shell 12 will be crimped, thereby with respect to dividing plate 20,22 set casings 12.At length show crimping 50 in Fig. 4, crimping 50 is conventionally forms.Subsequently, end cap 14,16 will be applied on the sub-component of shell.
Cost of material of the present invention is quite to save, and has alleviated sub-fraction weight, and does not jeopardize the anticorrosive or abrasion resistance properties of exhaust component 10.
