Definitions
- the invention relates to a device for exhaust gas recirculation (EGR), in particular in diesel engines according to the preamble of patent claim 1.
- EGR exhaust gas recirculation
- EGR exhaust gas recirculation
- EGR exhaust gas recirculation
- Known embodiments of the exhaust gas recirculation (EGR) lead within an EGR route an exhaust line branched off from the engine exhaust side for returning to the fresh air path of the engine. They include a cooling device connected to the cooling system of the engine as an exhaust gas / coolant heat exchanger, and an EGR valve whose task is to regulate the recirculated exhaust gas quantity in accordance with the map data of the engine.
- diesel engines are concerned with using exhaust gas recirculation (EGR) for NOx reduction.
- the engine should be supplied on its fresh air side as cold as possible exhaust gas to keep the process temperature as low as possible for the stated purpose. Therefore, according to a known embodiment, it is provided to arrange the EGR valve on the cold side of the heat exchanger, but this entails the disadvantage that the EGR valve tends to sloppy at operating points below the condensation point of the exhaust gas. In another known embodiment, therefore, the EGR valve is arranged on the hot side of the réelletau ⁇ shear, which, however, it is thermally highly loaded and therefore only the limited life, similar to a wear component achieved.
- the present invention has the object to provide an improved device of the type mentioned ⁇ initially, which avoids the disadvantages mentioned, in particular the EGR valve thermally relieved in favor of a longer life, and thus the requirements of an efficient EGR feedback for Rugged and durable industrial diesel engines suffice.
- this object is achieved with a device according to claim 1 and further embodiments and a method according to claim 11 and further embodiments.
- Characterized in that thedevor ⁇ direction is divided into an AG precooler and followed by an AG main cooler according to the proposed invention, it is possible that the EGR valve between AG-forward and AG- to arrange the main condenser, whereby there is a valve housing for receiving the EGR valve is provided.
- the branched off exhaust gas is first cooled in the AG precooler and after passing through the EGR valve in the AG main cooler, so that a mixing temperature promoting the reduction of NOx on the fresh air side of the engine is achieved.
- the series connection of AG precooler and AG main cooler according to the invention also counteracts the influence of the disadvantageous cooling aging since a drop in the cooling effect of the AG precooler is compensated by the downstream AG main cooler.
- Both the AG and the AG-Precooler main cooler can advantageously be designed as castings, ent ⁇ either in one piece or multi-part form.
- the AG precooler and the valve housing are formed as a one-piece construction ⁇ part.
- a manufacturing simplification results from the further variant that the AG precooler and / or the AG main cooler each have a multi-part housing aufwei ⁇ sen.
- This combines the advantageous possibility that in each case a prefabricated heat exchanger insert part can be installed in the radiator housing and that in this way the AG precooler and the AG main radiator can be equipped with the same heat exchanger inserts.
- heat exchanger insert parts for the exhaust are preferably commercial ⁇ Liche tube bundle heat exchanger in question.
- the variant may be advantageous that in each case a subsequent ⁇ DTder to the valve housing the housing part of the precooler and / or the main ⁇ cooler is formed integrally with the valve housing; As a result, two separate components can be saved and there are no sealing flanges with screwed parts.
- the engine cooling ⁇ water for the EGR system is taken from the engine cooling water circuit and advantageously first supplied to the valve housing. In this it is divided into several cooling water paths. One passes through the AG precooler and then the AG main cooler; another flows through the valve body, thereby cooling the EGR valve from the outside, whereafter it is supplied to the engine cooling system; another cooling water path flows through the interior of the EGR valve, where it cools its electrical components. Ultimately, all cooling water paths open again
- Hose lines in the engine cooling water of the engine may be passed over the oil cooler and then flow back to the radiator.
- tube bundle heat exchanger elements are basically also heat exchangers with cast chambers for guiding the exhaust stream, the chambers are surrounded on the outside by cooling water.
- an improvement in the heat transfer can be achieved in a simple manner by the fact that the inner casting surfaces of the heat exchangers are formed on one or both sides relatively rough, so that gas turbulence as well as water arise.
- a first cooling water path is passed into the AG precooler and passes from there directly into the AG main cooler; the Ventilgepatu ⁇ se is supplied here by a separate cooling water path for the housing cooling and the internal cooling of the EGR valve.
- the invention proposes that a coolant telan gleich forms the coolant supply to the valve body that the AG-pre-cooler is fitted to the valve housing at ⁇ closed and with a coolant outflow for AG- main cooler. It is also proposed that the valve housing is provided with further coolant outlets to the engine cooling system and / or other engine-side heat exchangers.
- the AG precooler has separate cooling ducts for cooling the exhaust gas, extending in the longitudinal direction of the AG precooler, for conducting the coolant.
- a coolant connection forms the coolant inflow to the AG precooler, the coolant outflow of which is connected directly to the AG main cooler, whose coolant outflow in turn is connected to the engine cooling system.
- exhaust gas recirculation method After a particularly advantageous in diesel engines exhaust gas recirculation method is provided that the exhaust branched off from the exhaust gas of the engine within ⁇ half an EGR line in series first by an AG precooler then to measure the AG-return rate and their distribution by an AGR Valve and finally sent through a AG main cooler.
- the refrigerant is respectively branched off from the cooling system of the Mo ⁇ tors;
- the cooling water diverted thereby is first passed in series through the AG precooler, then through the AG main cooler. At least a subset of the diverted cooling water is through a valve housing receiving the EGR valve and / or through the Passed inside the EGR valve and possibly branched off at the outside of the EGR route existing engine side heat exchanger.
- the cooling water conducted through the AG precooler is cooled there to a temperature well above the condensation point of the exhaust gas.
- the exhaust gas thus passes through the EGR valve, without this being thermally overloaded or endangered by condensation.
- the exhaust gas branched off from the exhaust manifold of the engine at 550 to 600 ° C in the AG precooler is cooled by about 200 to 250 ° C.
