Definitions

  • the invention relates to the use of such a cylinder head.
  • Internal combustion engines have a cylinder block and a cylinder head, which is used to form the individual cylinder d.
  • H. Combustion chambers are interconnected.
  • the cylinder block has a corresponding number of cylinder bores for receiving the pistons or the cylinder tubes.
  • the pistons are guided axially movably in the cylinder tubes and, together with the cylinder tubes and the cylinder head, form the combustion chambers of the internal combustion engine.
  • the cylinder head is often used to hold the valve train.
  • an internal combustion engine requires control means and actuators to operate these controls.
  • the expulsion of the combustion gases via the outlet openings and the filling of the combustion chamber that is the suction of the fresh mixture or the fresh air via the inlet openings takes place.
  • four-stroke engines use almost exclusively globe valves as control members, which oscillate during operation of the internal combustion engine Execute lifting movement and thus release the inlet and outlet openings and close.
  • the required for the movement of the valves valve actuating mechanism including the valves themselves is referred to as a valve train.
  • the inlet ducts leading to the inlet openings and the outlet ducts or exhaust ducts adjoining the outlet openings are at least partially integrated in the cylinder head according to the prior art.
  • the exhaust pipes of the at least two exhaust ports of a single cylinder are often - within the cylinder head - merged into a cylinder associated partial exhaust gas line, these partial exhaust gas lines are then combined outside the cylinder to form a single overall exhaust line.
  • the merging of the exhaust pipes to the entire exhaust line is referred to in general and in the context of the present invention as exhaust manifold or manifold.
  • the exhaust gases Downstream of the manifold, the exhaust gases are then optionally supplied to the turbine of an exhaust gas turbocharger and / or one or more exhaust aftertreatment systems.
  • the turbine As close to the outlet of the internal combustion engine, in order to make optimum use of the exhaust enthalpy of the hot exhaust gases and to ensure a rapid response of the turbocharger.
  • the way the hot exhaust gases to the various exhaust aftertreatment systems should be as short as possible, so that the exhaust gases little time is granted for cooling and the exhaust aftertreatment systems as fast as possible Reach operating temperature or light-off temperature, in particular after a cold start of the internal combustion engine.
  • the exhaust manifold is partially or fully integrated with the cylinder head.
  • a cylinder head in which connects to each outlet opening an exhaust pipe and merge the exhaust gas lines of the cylinder within the cylinder head to form an overall exhaust gas line, is the subject of the present invention.
  • Such a cylinder head is characterized by a very compact design, wherein the total distance traveled by the exhaust pipes of the exhaust manifold has been minimized.
  • the use of such a cylinder head also leads to fewer components and consequently to a reduction in costs, in particular the assembly and deployment costs.
  • the heat released during combustion by the exothermic, chemical conversion of the fuel is partly dissipated via the walls delimiting the combustion chamber to the cylinder head and the cylinder block and partly via the exhaust gas flow to the adjacent components and the environment.
  • a portion of the introduced into the cylinder head heat flow must be withdrawn from the cylinder head again.
  • the liquid cooling requires the equipment of the internal combustion engine or the cylinder head with a coolant jacket d. H. the arrangement of the coolant through the cylinder head leading coolant channels, which causes a complex structure of the cylinder head construction. In this case, the mechanically and thermally highly stressed cylinder head is weakened by the introduction of the coolant channels on the one hand in its strength. On the other hand, the heat must not be directed to the cylinder head surface as in the air cooling, to be dissipated. The heat is already in the interior of the cylinder head to the coolant, usually mixed with additives added water. The coolant is thereby conveyed by means of a pump arranged in the cooling circuit, so that it circulates in the coolant jacket. The heat given off to the coolant is removed in this way from the interior of the cylinder head and removed from the coolant in a heat exchanger again.
  • a coolant jacket is integrated in the cylinder head according to the prior art in a cylinder head of the present type.
  • EP 1 722 090 A2 discloses the registration EP 07110193.5 ,
  • Modern internal combustion engines are increasingly equipped with a cylinder head of the type in question. Increasingly, an exhaust gas recirculation is provided.
  • Exhaust gas recirculation ie the recirculation of combustion gases from the exhaust gas side to the intake side of the internal combustion engine, has been identified as being expedient in order to comply with future limit values for pollutant emissions, in particular the limit values for nitrogen oxide emissions. Since the formation of nitrogen oxides requires not only an excess of air but also high temperatures, there is a concept for reducing nitrogen oxide emissions It is to develop combustion processes with lower combustion temperatures, wherein the exhaust gas recirculation is a means to lower the temperatures.
  • Exhaust gas recirculation is also suitable for reducing emissions of unburned hydrocarbons in the partial load range.
  • the exhaust gas can basically be branched off downstream or upstream of an exhaust gas aftertreatment system provided on the exhaust side or of a turbine of an exhaust gas turbocharger, i. be removed.
  • the line for returning the exhaust gas branches off from the total exhaust gas line as a rule.
  • the return line must be connected to the entire exhaust line, for example by means of a flange connection.
  • the joint is on the one hand a potential leakage point for the unwanted escape of exhaust gases, which implies high demands on the seal.
  • this connection is thermally highly loaded by the hot exhaust gases, so that high demands are placed on the execution of the connection. If the entire exhaust line made of high temperature resistant material, the compound must also be made of costly and difficult to process material.
  • the prior art also includes concepts in which a line for exhaust gas recirculation is integrated into the cylinder head, wherein the return line branches off from an at least partially integrated in the cylinder head exhaust manifold.
  • the integrated into the cylinder head tapping point allows the one-piece design of manifold and return line d. H. the avoidance of training and sealing a non-positive connection point. Furthermore, the integration of the return line leads to a reduction in the number of components and a more compact design. The latter also supports the effort to achieve as dense as possible a packaging of the drive unit in the engine compartment.
  • a cylinder head with a built-in cylinder head tapping point for exhaust gas recirculation describes, for example, the GB 2 370 073 A .
  • the return line branches off from a partial exhaust gas line of a cylinder with two outlet openings, wherein the first portion of the return line is employed against the flow direction of the exhaust gas in the used partial exhaust gas line, thus making it more difficult for exhaust gas to flow out of the associated cylinder.
  • a special casting core must be provided, since the entire return line extends within the cylinder head and this section can not be formed in any other way, which makes the production difficult.
  • the cylinder head In order to integrate the return line completely in the cylinder head, the cylinder head must also have the necessary material substance, which usually leads to an increase in weight.
  • the Indian GB 2 370 073 A described cylinder head also has an integrated only partially in the cylinder head exhaust manifold, so that the distance of the exhaust pipes and partial exhaust gas line to a possibly located outside of the cylinder head total exhaust gas line is comparatively long. This has the consequence that the return line is actually acted upon only with the exhaust gas of the individual cylinder or can be diverted from the partial exhaust gas line this line.
  • a cylinder head according to the preamble of claim 1 which is equipped with a built-in cylinder head tapping point for exhaust gas recirculation and with which the known prior art disadvantages are overcome and in particular high exhaust gas recirculation rates can be achieved.
  • Another object of the present invention is to show uses of such a cylinder head.
  • the cylinder head according to the invention has - in contrast to that in the GB 2 370 073 A described cylinder head - via a fully integrated in the cylinder head exhaust manifold, which is why the distances of the individual exhaust pipes are comparatively short up to the total exhaust gas line. Due to the shorter flow paths, the return line for the individual partial exhaust gas streams of all cylinders or outlet openings is comparatively easily accessible. This advantageously leads to the fact that the return line diverging from the partial exhaust line of a single cylinder can be acted upon or acted upon by the exhaust gas of all the cylinders of the internal combustion engine.
  • the cylinder head according to the invention differs from concepts in which the cylinder head has an only partially integrated manifold, and also of concepts in which the return line branches off from the entire exhaust line or an exhaust pipe of a single outlet opening.
  • the first of the invention underlying subtask is solved, namely to provide a cylinder head of the generic type, with a cylinder head in the integrated tapping point is equipped for exhaust gas recirculation and can be achieved with the high exhaust gas recirculation rates.
  • the production simplifies that means the formation of the branching off of the partial exhaust line section of the return line considerably.
  • the return line - depending on the individual case - partially or completely be introduced by means of machining production process in the cylinder head blank.
  • the return line can also be partially or completely formed already during the casting of the cylinder head blank, which can be done by introducing a simple, outwardly open and therefore easily removable core.
  • a part of the return line can be formed during the casting of the cylinder head blank, the return line and the partial exhaust line remaining separated by an initially remaining wall. The subsequent removal of the wall then ensures the connection of the two lines.
  • a uniform cylinder head blank can be made, in which can be selectively introduced by reworking a line for the return of exhaust gas or not.
  • Embodiments of the cylinder head in which the line for returning exhaust gas runs in a straight line are advantageous.
  • a straight-line course can serve to shorten the length of the return line and thus to reduce the volume of the line. This in turn improves the response of the exhaust gas recirculation, which is considered to be advantageous.
  • Embodiments of the cylinder head in which the line for returning exhaust gas runs essentially parallel to the longitudinal axis of the cylinder head are advantageous.
  • the return line usually connects laterally to the exhaust manifold and is not guided in the direction of the cylinder longitudinal axis up or down.
  • the exhaust gas recirculation line connects to the partial exhaust gas line to form a funnel-shaped inlet portion.
  • the diameter of the return line at the junction increases in the direction of the partial exhaust line, so that a funnel-shaped inlet region is formed, which supports the influx of exhaust gas, both the inflow from the cylinder, which is assigned to the partial exhaust gas line used for the return, and the inflow from the other cylinders. This is advantageous in particular with regard to the realization of high return rates.
  • the cylinder head walls forming the partial exhaust gas line should preferably be continuous d. H. flow smoothly into the return line.
  • embodiments of the cylinder head are also advantageous in which the walls of the conduit for returning exhaust gas to form the funnel-shaped inlet region bulge, whereby a trumpet-shaped inlet region is formed.
  • An inlet area which widens towards the partial exhaust gas line also leads to a reduction of the pulsation. If the inlet area to the partial exhaust gas line has curved, ie rounded, transitions, it is possible to influence the inflow conditions with the aid of the size of the radii of these rounded transitions.
  • the use of different radii on the side facing away from the exhaust gas line on the one hand and On the other hand, on the side facing the overall exhaust gas line allows a targeted distribution of the exhaust gas streams used for the return.
  • This embodiment is advantageous because the cylinder head in this way only slightly by the introduction d. H. the integration of the return line is weakened or affected. In particular, the length of the return line is shortened, whereby the volume of the line is reduced, which - as already stated above - improves the response of the exhaust gas recirculation. Such a running return line also limits the interpretation of the cylinder head construction with respect to other requirements or functions as little as possible.
  • the cylinder head is anyway a thermally and mechanically highly loaded component, since the cylinder head already have a variety of tasks and functions.
  • the cylinder head not only receives the valvetrain as described above, but also includes the bores into which the bolts for connecting the cylinder head to the cylinder block are inserted.
  • additional lines for venting the crankcase are provided in the cylinder head.
  • a cylinder head with integrated exhaust manifold has a comparatively bulky coolant jacket due to the high thermal load.
  • a coolant jacket is introduced into the cylinder head, which has a lower coolant jacket, which is arranged between the exhaust pipes and the mounting end face of the cylinder head, and an upper coolant jacket, which is arranged on the side opposite the lower coolant jacket side of the exhaust pipes, wherein these two coolant jackets are additionally connected by means of passages.
  • the line for recirculation of exhaust gas has the smallest possible volume, which can be realized for example by the external connection of the return line to the exhaust manifold.
  • embodiments of the cylinder head in which the coolant jacket integrated in the cylinder head at least partially surrounds the line for returning exhaust gas are advantageous.
  • the exhaust branched off from the exhaust manifold, provided for a return exhaust gas is already cooled in the cylinder head.
  • the thermal load of a downstream of the return line or the tap point provided valve for controlling the return rate (EGR valve) and / or a seal decreases.
  • An optionally provided additional radiator for cooling the recirculated exhaust gas may therefore be smaller in size.
  • Increasing the density also reduces the volume, resulting in a decrease in flow losses.
  • a cylinder head according to one of the aforementioned types in particular in a supercharged internal combustion engine, since the exhaust gas recirculation and charging are often used in combination and a supercharged internal combustion engine is charged thermally higher.
  • the dimensioning d. H Determining the length of the exhaust ducts in supercharged internal combustion engines with respect to the combustion process of lesser importance than uncharged internal combustion engines, so that in turbocharged internal combustion engines, the generally short length of the cylinder head integrated manifold has no negative impact on the performance of the internal combustion engine.
  • the use of the cylinder head according to the invention is advantageous in particular in internal combustion engines that are charged by turbocharging.
  • the turbine of the exhaust gas turbocharger is arranged in the overall exhaust line, thereby increasing the exhaust pressure upstream of the turbine and thus the exhaust pressure in the manifold, which in turn facilitates the introduction of the exhaust gas streams in the return line or reinforced, so that high return rates can be realized ,
