Definitions
- the invention relates to a device for recycling exhaust gases at a Internal combustion engine according to the preamble of the main claim (see e.g. WO 96/21097 or EP-A-0586123).
- the invention has for its object a device for recycling of exhaust gases in an internal combustion engine according to the above Kind in such a way that at the point of introduction of the recirculated exhaust gas optimal temperature conditions can be achieved.
- the inventive device for recycling exhaust gas at a Internal combustion engine is an advantageous development of the generic type Arrangement as in the intake duct of the internal combustion engine in the direction of flow behind a throttle in a simple way in particular amount of recirculated exhaust gas optimized with regard to the temperature can be introduced is.
- a valve is inserted into the exhaust gas recirculation line a predetermined quantitative ratio of exhaust gas and / or fresh air and thus an adjustable air-exhaust gas mixture for introduction into the intake duct generated.
- the fresh air can advantageously be from one Air filters in the intake tract of the internal combustion engine are branched off.
- the quantitative ratio can be set advantageously via the clock ratio, wherein the advantageous mixture by adding air at intervals and / or exhaust gas is controlled.
- the clock ratio of the clocked valve can be selected so that the proportion of the exhaust gas in the air-exhaust gas mixture for example in the range from 20% to 40%, the Fresh air in a selected embodiment a temperature of approx. 60 ° C and the exhaust gas has a temperature of approx. 222 ° C.
- the temperature is approx. 157.5 ° C with a share of the recirculated exhaust gas of 30%; this corresponds to the embodiment in about a temperature reduction of 29%.
- the temperature is approx. 125 ° C a share of the recirculated exhaust gas of 20%; this corresponds approximately a temperature drop of 44%.
- the device according to the invention is a cooling device for upstream of the clocked valve the recirculated exhaust gas is present, which is connected to an existing cooling circuit is connected for the internal combustion engine.
- An embodiment of the device according to the invention is based on the drawing explains, the figure being a schematic diagram of an exhaust gas recirculation (EGR) for an internal combustion engine with a clocked valve shows.
- EGR exhaust gas recirculation
- the exhaust gas is at a first input clocked valve 8 guided, the second input via a fresh air line 9 is connected to the air filter 1.
- a clocked valve 8 An air-exhaust gas mixture is generated, which is connected via a line 10 to an introduction point 11 is performed on which the mixture in the intake flow before Intake pipe 3 can flow.
- a Mixture can be generated in line 10, in which the proportion of the exhaust gas is in the range of 20% to 40%.
