Definitions
- the invention relates to an arrangement for returning Exhaust gas in an internal combustion engine of the genus Main claim.
- Thermal peaks occur especially in such arrangements in the areas of the seals, usually from Plastic, at the connection of the connecting line for the recirculated exhaust gas and in areas close to the inflow opening are opposite. It is often difficult here due to the relatively small cross sections and relative to dissipate sufficient heat over long distances. In many applications related to direct injection Motors is also used because of the expected return rate of the exhaust gas (up to 50%) often the demand for one cylinder-selective introduction of the exhaust gas posed what leads to further thermal problems.
- the invention has for its object an arrangement of the type mentioned in the introduction so that an optimal Lowering the temperature is possible.
- the solid heat-conducting part a tubular insert that integrates inside the intake pipe is.
- This insert lies with an end face under thermal contact on the cylinder head.
- This heat transfer can also be increased if necessary be that the end face resting on the cylinder head of the insert has an enlarged diameter.
- the tubular connecting line for the recirculated exhaust gas through the wall of the intake pipe led out.
- the connecting line and the insert are gas-tightly connected to each other, which means none Seals between the connecting line and the intake pipe are necessary.
- the inflowing exhaust gas bounces thus on the inner wall of the cooled insert and places therefore no increased thermal stress on the plastic of the intake pipe.
- a recess in the intake pipe is to form a radial distance from the connecting pipe and thus to prevent a possible thermal load on the intake pipe in this area.
- FIG 1 is a cylinder head 1 of an internal combustion engine with the essential parts shown here.
- the exhaust gas in the connecting line 4 has one due to the combustion in the engine correspondingly high temperature, which the intake pipe and the neighboring aggregates possibly damage, as these are for normal air temperatures are designed and mostly made of plastic are made.
- connection flange 2 for the recirculated exhaust gas is a Cooling channel 5 connected through which for the engine coolant required anyway according to arrows 6a (inlet) and 6b (drain) flows.
- this cooling channel 5 around the connecting flange 2 and thus around the connecting pipe 4 for the recirculated exhaust gas in shown another view.
- the flange contour after the Figure 2 is with two screws 7 on the plastic intake pipe 2 attached. In the middle of this flange contour is the connecting pipe 4 inserted.
- FIG. 1 An exemplary embodiment can be seen in FIG which a manifold 10 for recirculated exhaust gas on a Cylinder block 11 is arranged.
- the recirculated exhaust gas flows through the cross section 12 of the distributor pipe 10 and is in each case via tubes 13 and corresponding connection flanges 14 passed into an intake pipe 15.
- the distributor pipe 10 to the cylinder head 11 can preferably already existing screw connections here 16, possibly via a metal sleeve 17, for the intake pipe 15 can be used.
- cooling channel 18 in FIG. 4 arranged through which the coolant flows.
- a cooling channel 19 also at least partially integrated into the distributor pipe 10 be, with additional seals here 20 are necessary.
- the one has metallic insert 21, which in the plastic intake pipe 22 is attached such that an end End 23 is in thermal contact with the cylinder head 24.
- a cooling channel 25 is also arranged in the cylinder head 24.
- a connecting tube 26 for the side recirculated exhaust gas introduced firmly and gas-tight.
- To the surrounding Plastic of the intake pipe 22 is here free distance 27 attached because of the relatively high temperatures of the connecting pipe 26, the plastic of the intake pipe 22 should not damage.
- To cool the insert 21 still too is to improve according to Figure 7 the surface of the front End 23 of the insert enlarged so that an even better one Thermal contact between the insert 21 and the cylinder head 24 is reached.
