Definitions
- the invention relates to a device for exhaust gas recirculation for an internal combustion engine with an exhaust gas cooler that has a flow path for a liquid coolant and a Has flow path for exhaust gas and with a determining the recirculated exhaust gas amount by means of an adjusting element adjustable valve, the exhaust gas cooler and the Connect the valve directly to one another and form a structural unit.
- the return of cooled exhaust gas to an internal combustion engine is particularly useful for Lowering diesel emissions known, ATZ Automobiltechnische Zeitschrift 99 (1997) 9 (R. Lutz: Reduction of diesel emissions by returning cooled exhaust gas).
- the Exhaust gas recirculation valve (EGR valve) and the exhaust gas cooler (exhaust gas heat exchanger) are common components that are independent of one another, located at different points in the vehicle installed and connected to each other by means of an exhaust pipe.
- the invention has for its object a device of the type mentioned to be designed so that the actuating element is subjected to as little thermal stress as possible.
- control element on a component of the exhaust gas cooler is attached, which is cooled by the coolant flowing through the exhaust gas cooler.
- control element is attached to a component, that with one or more channels for a liquid coolant is provided.
- Both configurations enable the valve on the exhaust gas inflow side to arrange the exhaust gas cooler.
- the arrangement of the Valve on the inflow side of the exhaust gas cooler, i.e. on the Side on which the hot exhaust gas flows in has the advantage that the risk is relatively low that residues of the exhaust gas attach to the valve and its valve elements.
- This Danger when arranging the valve after the exhaust gas cooler Increased exists leads to control elements must be provided with relatively large actuating forces that an adhesion of the valve elements due to deposited Exhaust residues can safely overcome.
- When arranging on the exhaust gas inflow side there is a risk of deposits of Exhaust gas residues significantly lower.
- the risk that the control elements, in particular electrical control elements, thermally overloaded are. This thermal overload is counteracted that the control element is attached to a component, whose temperature is significantly lower than the temperature of the exhaust gas coming from the internal combustion engine.
- the channel or channels of the component carrying the actuating element connect to a coolant inlet to the exhaust gas cooler.
- none outer connecting lines between the cooling Channels of the component carrying the actuator and to the Exhaust cooler must be provided.
- the exhaust gas cooler has an elongated shape, and that the control element essentially in parallel next to the exhaust gas cooler is arranged. This results in a compact Design that is relatively easy to accommodate in a vehicle is.
- the assembly shown in FIGS. 1 and 2 contains an exhaust gas cooler 10 and a valve 11, a so-called EGR valve.
- the valve 11 and the exhaust gas cooler 10 are preferably arranged so as it is in Figure 2 of the literature mentioned at the beginning is shown, i.e. the valve 11 is on the exhaust gas inlet side of the exhaust gas cooler 10.
- the valve 11 is provided with a connecting flange 12, with which it comes to an exhaust pipe coming from an internal combustion engine can be connected.
- Inside the valve body is an adjustable valve element in a manner not shown provided to which a valve seat is assigned.
- the Valve determines the amount of exhaust gas that is sent to the exhaust gas cooler 10 flows.
- the valve element is by means of an actuator 13 adjusted, in particular an electromagnetic actuator. This determines depending on the specified engine data Valve 11 the amount of exhaust gas that is supplied to the internal combustion engine Fresh air can be added.
- the actuator 13 can work so that there is a two-point control or also carries out a cross-sectional regulation.
- the valve 11 is with Provided fasteners 14, by means of which it is attached to a Bracket can be attached, for example on the engine block of the internal combustion engine.
- the valve 11 has one in approximately funnel-shaped distribution chamber 15, by means of the exhaust gas is supplied to the exhaust gas cooler 10.
- the exhaust gas cooler 10 is designed in principle as this the reference mentioned at the beginning (ATZ Automobiltechnische Journal 99 (1997) 9) is known. He owns his Each end has a floor in which the ends of one Variety of rectangular tubes are used, which are among themselves are arranged at a distance.
- the tube bundle out Rectangular tubes are surrounded by a jacket 16 which is attached to the circumferential chambers 17, 18 forms both end regions.
- the Chambers 17, 18 are provided with connections 19, 20 through the coolant of the engine cooling circuit is supplied and removed becomes.
- the coolant preferably flows parallel to the exhaust gas in the exhaust gas cooler 10, so that the connection 19 is an inlet connection and port 20 is a return port.
- the end of the exhaust gas cooler 10 facing the valve 11 is with provided a flange 23, which preferably also the bottom for forms the tube bundle of the exhaust gas cooler.
- the housing of the valve 11 is flanged.
- the control element 13 is fastened next to the exhaust gas cooler 10, that is essentially parallel to the jacket 16 of the exhaust gas cooler is aligned.
- the flange 23 is relatively thick-walled trained so that he has a thermal separation between the housing of the valve 11 and the actuator 13 forms.
- the flange 23, which of the through the exhaust gas cooler 10th flowing coolant is clearly cooled lower temperature than the valve housing of the valve 11, so that the actuator 13 is thermally separated from the valve 11 and is accordingly only relatively slightly thermally stressed.
- an exhaust gas cooler 10 and a valve 11 formed unit of the embodiment of FIGS. 3 and 4 corresponds in the basic structure and in the basic Arrangement of the embodiment according to FIGS. 1 and 2.
- the exhaust gas cooler 10 has a stronger flange 24 provided the in a manner not shown with by one Feed port 25 leading to the chamber 17 of the jacket 16 Channels is provided, through which the coolant of the internal combustion engine to the chamber 17 of the exhaust gas cooler 10 is performed.
- the flange 24 is therefore actively cooled, so that an even better thermal separation between the valve 11 and the actuator 13 is obtained.
