Definitions
- the present invention relates to a control method of an air supply of an internal combustion engine in a motor vehicle, in particular a control method for a turbocharged diesel engine.
- the power generated is determined essentially by the injected fuel quantity, the fuel pressure lying on ⁇ and by the amount and pressure of the supplied air. Compared with the regulation of the fuel pressure, there are larger physical delays in regulating the air supply due to physical reasons. This applies in ⁇ play as the amount of air supplied and the pressure of the supplied air ⁇ . Since the delivery of the requested air quantity thus takes place only after the lapse of vehicle-specific dead times, the acceleration behavior of the motor vehicle is thereby impaired.
- turbocharger In a motor vehicle with a turbocharger, the cause of this behavior lies in the functioning of the turbocharger.
- the turbocharger is usually mechanically coupled to the exhaust passage of the internal combustion engine. Therefore, the performance of the
- Turbocharger for example, the size of the generated charge air ⁇ pressure, directly from the transported exhaust gases in the exhaust duct. If for example only exhaust a small amount and / or low exhaust gas temperature produced by the internal combustion engine, which is the case at low engine speeds and low engine load of the internal combustion engine, of the gene by the turbocharger ⁇ rierbare charge air pressure is comparatively low. If a sudden increase in power of the internal combustion engine is requested, the turbocharger requires a certain amount of time to generate a supportive charge air pressure of sufficient height. This state of short-term lack of support of the internal combustion engine by a turbocharger is generally known as "turbo lag". In order to overcome the above drawbacks or at least limit conditioner ⁇ two approaches are known in the art.
- the second approach is to use a two-stage turbocharger system, which is also referred to as twin-turbo or Registerauf ⁇ charge. Investigations of such systems demonstrate the potential of the air path optimization using kannstufi ⁇ ger turbocharger systems. For example, in an Opel study, the performance of a 1.9-liter common-rail diesel engine was increased from 110 kW to 156 kW using a two-stage turbocharger technology. However, with respect to two-stage turbocharger systems, a significant drawback is that they are associated with significantly greater hardware costs to implement such an airpath as compared to standard turbochargers.
- the present invention has for its object to provide a more cost effective compared to prior art optical ⁇ -optimized air supply for an internal combustion engine.
- control method of an air supply of an internal combustion engine in a motor vehicle according to independent claim 1.
- Advantageous Ausgestal ⁇ obligations and further developments of the present invention are defined from the following description, out of the drawing and the appended claims.
- the control method according to the invention is particularly suitable for motor vehicles with a diesel engine and turbocharger. It comprises the following steps: a) transmission of route data of a route to be traveled by the motor vehicle to an engine control unit b) recognition of at least one future power increase point of the internal combustion engine based on the route data on which a request for an increased output of the internal combustion engine is to be expected, and c) preparing the increased power output so that the internal combustion engine is briefly put into a state of increased power output.
- the engine control unit of the internal combustion engine or of the motor vehicle is supplied with the data of the route to be covered. This is done for example via a navigation system or a manual input of route data, which are then forwarded to the engine control unit. Based on the off ⁇ evaluation of such data is for the engine control unit recognizable at which points of the route of the driver of the
- this preparation state is generated in a turbocharged internal combustion engine by injecting and igniting a torque-neutral injection, so that an exhaust gas temperature of the internal combustion engine is increased and the turbocharger of the internal combustion engine is biased.
- the prestressed turbocharger minimizes the turbo lag known from the prior art, which in case of a sudden requirement of an increase in power of the Internal combustion engine leads to delay times in the cupboardabga ⁇ be the internal combustion engine.
- An embodiment of the control method according to the invention is constructed such that it can be realized with the standard components of an air path of the internal combustion engine.
- These standard components include, for example, a simple turbocharger without additional electrical systems. Therefore, with the present invention, an optimization of the power output of the internal combustion engine can be realized solely by internal engine measures. At the same time, this ensures that no increased hardware costs are required to implement the present invention.
- the idea underlying this invention consists in the predictive influencing of the exhaust gas properties for the reduction of the turbo lag. It is possible by analysis of route data, for example, an attached Na ⁇ vigationssystem, manual entry of route data or a different type of deposit are the travel route data provided future performance improvement points of the internal combustion engine with a high probability michsa ⁇ gen. Power increase dots represent points at which, for example due the route or the driving behavior of the driver, a request for an increased power output of the internal combustion engine is to be expected. Such performance enhancement points include driving on a freeway or highway, leaving a bend area or a pass road or similar situations.
- control method is, for example, in a Motor Tavernge- the internal combustion engine advises stored there leads ⁇ its data evaluation, and transmits commands to connected components.
- the engine control unit firstly checks whether the navigation system is switched on and / or is operatively connected in order to integrate it into the further course of the control method in the event of a positive response. If no navigation system is available, it is also conceivable manually or retrieve them from a memory in which they are stored.
- step S2 If no navigation or route data is available, the use of normal control concepts is instructed in step S2. Thus, for example, with the navigation system switched off or defective, the engine control unit would already leave the control process at this point. However, it would poll the availability of navigation and / or route data constantly or at regular intervals in order to restart the control procedure (step S0).
- step S3 follows.
- the navigation system route data are forwarded to a data evaluation after entering a destination by the driver of the motor vehicle.
- the data evaluation checks the received route data, whether there are one or more performance increase points of the internal combustion engine in the course of this route. This increase in performance points indicate route points at which the driver of the vehicle is expected ⁇ clearly request a increased power output of the internal combustion ⁇ machine.
- Gleichzei ⁇ tig engine control unit receives continuously or at regular intervals, information about the state of the internal combustion engine. This information includes, for example, the rotational speed of the internal combustion engine and the load or the output torque of the internal combustion engine.
- the engine control unit checks the condition of the internal combustion engine. This includes according to one embodiment, the examination of the state of the turbocharger and its ability to support a gestei ⁇ siege power output of the internal combustion engine as quickly as possible. Furthermore, the engine control unit checks whether in dependence from the current position of the motor vehicle on the predetermined route, the achievement of a performance increase point is imminent. For example, if the performance enhancement point is imminent and the turbocharger is not in a "pre-stressed" condition, then step 4 follows.
- turbocharger It is now based on the test of the internal combustion engine, a special injection concept introduced to bias the turbocharger.
- the special injection concept is started in a targeted manner at a time, so that the turbocharger is set to its prestressed state even before reaching a possible power increase point. This ensures that the turbocharger with or without a minimized turbocharger supports a requested increased engine power output.
- step S2 follows. This has the consequence that the internal combustion engine is driven with normal control concepts.
- the control method After the performance increase point requirement with or without an on ⁇ an increased power output of the Brennkraftma- has been passed machine, the control method returns to its beginning to prepare again the possible achievement of performance improvement points along the planned route of the motor vehicle.
