Definitions
- the technical field to which the invention relates relates in the broadest sense to automotive engineering and Narrower internal combustion engines, where one Exhaust gas recirculation in the air supply system of the Internal combustion engine takes place.
- An arrangement according to the preamble of claim 1 is known known from DE 197 33 964 A1 and essentially has one Cooling device through which the exhaust gases flow, one Bypass line, which bypasses the cooling device, and a Valve arrangement on, by means of which the exhaust gases optionally through the cooling device or the bypass line are routed.
- the technical problem (object) of the invention consists in a further improvement of the emission values as well as the Fuel consumption of an internal combustion engine in connection with exhaust gas recirculation and a constructive one Simplification of the exhaust gas recirculation system.
- This task is performed by the exhaust gas recirculation system according to the Claim 1 solved.
- bypass line there is a bypass line, the one Bypasses cooling device for the recirculated exhaust gas, whereby before a switch is arranged in the cooling device, the inlet of which is connected to an exhaust gas recirculation line.
- This switch has two passages, one with the Cooling device and the other with the bypass line connected is. This is such that the exhaust gases alternatively through the cooling device or the bypass line are flowable.
- the switch is an integral part of the Cooling device and consists of exactly one bypass valve or exactly one bypass flap that exists in the Branch arranged in front of the cooling device and bypass line is and in a first operating position, the cooling device and in a second operating position the bypass line closes.
- the invention is based on the knowledge that the Return of the exhaust gases is not always cheap Results. In particular, it was recognized that in the Warm-up phase the temperature of the exhaust gases is too low to to achieve the desired success. According to the invention therefore a switch is provided in front of the cooling device so that in the warm-up phase, the exhaust gas around the cooling device be passed into the air supply system without cooling can get, which in the warm-up phase better Emission values and cheaper fuel consumption can be achieved. If the exhaust gases then in normal operation have a temperature at which cooling improves would lead to results, the switch is switched, so that the exhaust gases flow through the cooler and then accordingly get cooled into the air supply system.
- Fig. 1 shows an exhaust gas recirculation system with the schematic Representation of a four-cylinder internal combustion engine 1 with a Exhaust pipe system 2 and an air supply or Air intake system 3, which an air flow meter 4 and has a throttle 5.
- Essential part of the Exhaust gas recirculation system has an exhaust gas recirculation line 6 an exhaust gas recirculation valve 7 and a cooler 10. Die Exhaust gas recirculation line 6 opens into the air supply system 3, such as this can be seen in FIG. 1. It is controlled Exhaust gas recirculation via the exhaust gas recirculation valve 7. Another Description of the principle is not necessary here as this is well known to the person skilled in the art.
- a bypass line 17 bypassing the cooler 10, which is by a Bypass valve 18 is controlled in Fig. 1 as by the cooler 10 spatially separated valve shown.
- the cooler 10 shown in FIGS. 2 and 3 has one Inlet 11 and an outlet 12, each for the supply and the discharge of the coolant. There is also an inlet 13 provided for the supply of the exhaust gas according to a Arrow 14. The cooler also has an outlet 15 either cooled or not according to arrow 16 cooled exhaust gas is released.
- the cooler 10 bypasses the Bypass line 17.
- In the inlet area of the cooler according to Embodiment of FIG. 2 is integrated into the cooler Valve 18 is provided. 3 a flap 19 is provided.
- This valve 18 or the Flap 19 form a switch as bypass organs through which appropriate setting the exhaust either by the Cooler flows or is passed through the bypass line 17.
- the valve 18 and the flap 19 are with a control member 20 connected.
- valve 18 or the flap 19 is controlled as a switch by one not shown in FIGS. 2 and 3, but shown in FIG. 1 electronic control system 8. This is either dependent the temperature of the recirculated exhaust gas or load-dependent, speed-dependent or by others Motor parameters that are detected by a sensor. If in the warm-up phase the exhaust gases a relatively low temperature have, the exhaust gases through the bypass line 17th passed and get into the air supply system of the Internal combustion engine. When the engine warmed up is, flow through the exhaust gases with the corresponding position of the Soak the cooler and get into it with cooling Air supply system.
- the control of the valve 18 or the flap 19 in the Position shown in dashed lines for the warm-up phase preferably takes place against the force of the spring 21 Positive or negative pressure, preferably by negative pressure, or electric or otherwise.
