Definitions
- the invention relates to an exhaust gas recirculation line for internal combustion engines according to the preamble of claim 1.
- an exhaust gas recirculation line which is the exhaust gas line transversely to the longitudinal axis of the internal combustion engine in front of one of the front cylinder heads connects to the charge air line.
- FIG. 1 shows a top view of a cylinder head 1 with an exhaust gas recirculation system.
- the exhaust gas recirculation system essentially consists of an exhaust pipe 2, a Check valve 3, an exhaust gas cooler 4 and a charge air line, not shown here educated.
- the exhaust gas to be returned passes through coming from the exhaust line 2 initially a butterfly valve 5, then flows through the exhaust gas recirculation line 6 and passes through the check valve 3 when pressure peaks occur, and the exhaust gas cooler 4 into the charge air pipe.
- the exhaust gas is now from the exhaust pipe 2 to the exhaust gas cooler 4 by a Exhaust gas recirculation line 6 led into one of the end faces of the cylinder head 1 in such a way is integrated that it is guided through the cooling water chamber 7.
- a line is saved, which is on the front of the Cylinder head 1 would take up additional space: The line would be in their Radiate considerable heat to the environment when installing in a vehicle Risk of fire and should be isolated.
- Another advantage of the invention Arrangement is that by installation in the cooling water chamber 7 a noticeable pre-cooling of the exhaust gas is achieved, so that the actual exhaust gas cooler 4 can be dimensioned smaller.
- the cooling effect of the exhaust gas recirculation line 6 can be increased further by that it has exhaust fins cooling fins, which the exhaust gas recirculation line 6 in the longitudinal weighting pull through and the together with the cylinder head 1 in casting technique can be performed.
- the check valve 3 is a flap valve formed, which opens when 6 exhaust pressure peaks via the exhaust gas recirculation line meet a tongue 8 in the direction indicated by the arrow.
- the check valve 3 can advantageously be a structural unit with a seal 10 form which is arranged between the cylinder head 1 (Fig. 1) and the exhaust gas cooler 4 is.
- the deflection of the tongue 8 can be limited by a stop 9 in turn forms part of the seal 10.
- the exhaust gas flows after passing the tongue 8 in the exhaust gas cooler designed as a tube bundle heat exchanger 4 and after cooling in the charge air line.
- FIG. 3 A section III-III through the front end of the cylinder head 1 is shown in FIG. 3.
- the exhaust gas recirculation line 6 is embodied in two channels here.
- the two exhaust gas recirculation lines 6a, 6b penetrate the cooling water chamber 7.
- the exhaust gas is already here pre-cooled. A heat radiation to the environment is completely impossible, isolation is therefore not necessary.
- a butterfly valve 5 (Fig. 1) is provided, which by the actuator 5a can be actuated.
