Definitions

  • the technical field to which the invention relates concerns in the broadest sense the automotive technology and, in the narrower sense, internal combustion engines in which an exhaust gas recirculation takes place in the air supply system of the internal combustion engine.
  • An arrangement according to the preamble of claim 1 is known from DE 197 33 964 A1 and comprises essentially a cooling device, which is flowed through by the exhaust gases, a bypass line, which bypasses the cooling device, and a valve arrangement, by means of which the exhaust gases are selectively guided by the cooling device or the bypass line.
  • the technical problem (object) of the invention consists in a further improvement of the emission values and the fuel consumption of an internal combustion engine in connection with exhaust gas recirculation and a constructive simplification of the exhaust gas recirculation system.
  • a bypass line which bypasses a cooling device for the recirculated exhaust gas, wherein before the cooling device, a switch is arranged, whose inlet is connected to an exhaust gas recirculation line.
  • This switch has two passages, one of which is connected to the cooling device and the other to the bypass line. This is provided in such a way that the exhaust gases can alternatively be flowed through the cooling device or the bypass line.
  • the switch is an integral part of the cooling device and consists of exactly one bypass valve or exactly one bypass flap, which is arranged in the branch before the cooling device and bypass line and in a first operating position, the cooling device and in a second operating position closes the bypass line.
  • the invention is based on the finding that the recirculation of the exhaust gases does not always lead to favorable results.
  • the temperature of the exhaust gases is too low to achieve the desired result.
  • a switch is provided in front of the cooling device, so that the exhaust gas can be conducted around the cooling device in the warm-up phase, ie can reach the air supply system without cooling, whereby better emission values and more favorable fuel consumption can be achieved in the warm-up phase. If the exhaust gases are then in normal operation at a temperature at which cooling would lead to better results, the switch is switched so that the exhaust gases flow through the radiator and then get cooled accordingly in 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 an exhaust pipe system 2 and an air intake 3, which comprises a Heilströmungsmeß réelle 4 and a throttle 5.
  • An essential part of the exhaust gas recirculation system is an exhaust gas recirculation line 6 with an exhaust gas recirculation valve 7 and a radiator 10.
  • the exhaust gas recirculation line 6 opens into the air supply system 3, as the Fig. 1 can be seen.
  • the exhaust gas recirculation is controlled via the exhaust gas recirculation valve 7.
  • a bypass passage 17 bypassing the radiator 10, which is controlled by a bypass valve 18, is in FIG Fig. 1 shown as spatially separated from the radiator 10 valve.
  • Fig. 2 respectively.
  • Fig. 3 shown cooler 10 has an inlet 11 and an outlet 12, respectively for the supply and the discharge of the coolant.
  • an inlet 13 is provided for the supply of the exhaust gas according to an arrow 14.
  • the radiator further has an outlet 15, from which according to the arrow 16 either cooled or not cooled exhaust gas is discharged.
  • the cooler 10 bypasses the bypass line 17.
  • a valve 18 is provided in the inlet region of the radiator according to the embodiment of the Fig. 2 is integrated in the cooler.
  • a flap 19 is provided in the embodiment of the Fig. 3 . This valve 18 and the flap 19 form as bypass organs a switch, through which the exhaust gas either flows through the radiator with an appropriate setting or is passed through the bypass line 17.
  • valve 18 and the flap 19 are connected to a control member 20.
  • this control member presses a spring 21, the valve 18 in accordance with normal operation Fig. 2 in the normal operating position shown in solid lines, in which the exhaust gas is passed through the radiator.
  • Fig. 3 the corresponding position of the flap 19 is also shown in solid lines.
  • the exhaust gas flowing into the inlet 13 passes into the bypass line 17, thus bypasses the radiator 10 and passes uncooled into the outlet 15th
  • the valve 18 or the flap 19 is controlled as a switch by a in FIGS. 2 and 3 not, but in Fig. 1 This is done either depending on the temperature of the recirculated exhaust gas or load-dependent, speed-dependent or by other engine parameters that are detected by a sensor.
  • the exhaust gases When in the warm-up phase, the exhaust gases have a relatively low temperature, the exhaust gases are passed through the bypass line 17 and arrive uncooled in the air supply system of the internal combustion engine.
  • the exhaust gases flow through the radiator in the appropriate position of the switch and get targeted cooled in the air supply system.
  • valve 18 and the flap 19 in the position shown in dashed lines for the warm-up phase takes place against the force of the spring 21 by overpressure or negative pressure, preferably by negative pressure.
