Description

The present invention relates to a retrofittable electrical throttle module for a motor vehicle of the driving saddle type, in particular for a motorcycle. Moreover, the present invention relates to a system with an electronic control device, a wiring harness and an electrical throttle module. The invention further relates to a flow element for a power limitation or power reduction of an internal combustion engine of a motor-driven vehicle of the driving saddle type, in particular of a motorcycle. Incidentally, the invention relates to an arrangement with an air intake and at least one flow element. Finally, the invention relates to an internal combustion engine, in particular a gasoline engine, for a saddle-type vehicle, in particular for a motorcycle, with an injection device for injecting a fuel into a sucked air flow, with a throttle valve for regulating the intake air flow and / or a fuel / Air mixture, with a combustion chamber and with a system and / or with an arrangement of the aforementioned type.

The present invention relates to the field of power control, in particular the power reduction and / or power limitation, of internal combustion engines, in particular gasoline engines. When gasoline engine, a fuel-air mixture is sucked, this mixture is formed outside a combustion chamber or a combustion chamber of the gasoline engine. It is important that even with a variation of the performance of an optimal air / fuel ratio is ensured in order to prevent misfiring during combustion. Misfiring can lead to a bang in the exhaust and damage a muffler system, a catalytic converter and a lambda probe of the internal combustion engine.

Gasoline engines usually have a throttle valve, which regulates the combustion chamber supplied air and / or the amount of fuel / air. In order to maintain an optimal fuel / air ratio, it is necessary to detect the rotational position of the throttle and transmit it to an electronic control device of the internal combustion engine. For this purpose, usually a position sensor, such as a throttle potentiometer, is used, which generates a corresponding throttle valve signal in response to the rotational position of the throttle and transmitted via a signal line, such as a wire harness, to the electronic control device. The electronic control device uses the throttle signal among other things to control the fuel injection quantity. For this purpose, a corresponding control signal is transmitted to a (fuel) injection device of the internal combustion engine in response to the transmitted throttle signal to initiate the appropriate amount of fuel to maintain the desired fuel-air ratio in the combustion chamber. The controller senses the electrical potential of the throttle potentiometer and adjusts the amount of fuel injection so that the engine receives the amount of fuel required for the corresponding series engine output.

In order to meet legal requirements for design-related limitations of the maximum net power and / or the maximum speed of vehicles, especially motorcycles, it is known to use an electric or electronic throttle module for power limitation. In this case, a throttle valve signal is transmitted to the throttle module, wherein the throttle module generates a modified throttle valve signal when exceeding a predetermined limit value for the throttle signal and transmits as an input signal to the control device for controlling the fuel supply to the combustion chamber. The modified throttle signal results in reduced fuel delivery to the combustion chamber and thus power and / or speed reduction. When the predetermined limit value is exceeded, a voltage value of the throttle valve potentiometer, which is below the actual voltage value, can be transmitted by the throttle module as an electronic component to the control device. The control device thus receives the "wrong" information that an amount of fuel actually supplied to the internal combustion engine is to be released for too low an amount of fuel.

From the prior art, a retrofittable electrical throttle module is known, which is provided and designed for installation in the region of the throttle valve or the throttle valve potentiometer. The installation area around the throttle valve is difficult to access, which increases the assembly effort. In addition, the installation area is in the immediate vicinity of highly heated engine components of the internal combustion engine, which can lead to burns in the course of the insertion and / or dismantling of the electronic throttle module.

The DE 10 2005 029 862 A1 relates to a power control device for an internal combustion engine of a motorcycle. The power control device has an engine control module, wherein continuously information, such as the throttle position, are transmitted to the engine control module. This information is used to drive a fuel injector of the internal combustion engine to the optimum amount of fuel into the intake tract of the internal combustion engine. Moreover, the engine control module is configured to move the throttle to a position where a throttle position limit is exceeded to reduce the amount of airflow and thus the engine power output. The motor control module thus fulfills the function of a throttle module. A disadvantage here is that a change in the throttle function always requires an exchange of the entire engine control module and / or the reprogramming of the engine control module.

The present invention has for its object to provide an opportunity for a fast and easy to install, safe, cost-effective, easy to undo and current legal requirements sufficient power reduction and / or power limitation of motor vehicles, especially motorcycles.

The above object is achieved by a retrofittable electrical throttle module having the features of claim 1, by a system having the features of claim 10, by a flow element having the features of claim 11, by an arrangement having the features of claim 13 and by an internal combustion engine the features of claim 21 solved. Advantageous developments are the subject of the dependent claims.

A first aspect of the invention relates to a retrofittable electronic throttle module, which is connectable via a first interface with a wiring harness of the vehicle for signal transmission of a throttle signal from the wiring harness to the throttle module and a second interface with an adapted for power control of the internal combustion engine electronic control device is connectable for a signal transmission of an input signal from the throttle module to the control device for controlling the fuel supply to the internal combustion engine. The system according to the invention has for this purpose an electronic control device, a wiring harness and an electrical throttle module.

The solution according to the invention allows a safe, user-friendly and rapid installation and / or removal of the electrical throttle module for influencing the power of the internal combustion engine, wherein the throttle module is arranged for signal transmission between the wiring harness and the control device. For a direct signal transmission from the wiring harness to the throttle module and from the throttle module to the control device (and back) appropriately designed interfaces are provided. The solution according to the invention makes it possible to arrange the electric throttle module away from the throttle valve or the engine block and directly adjacent to the control device, the extent of the removal preferably being determined by the length of the cable harness. As a result, a person assigned with the assembly of the throttle module is kept away from heated engine components, whereby the risk of combustion when installing and / or removing the throttle module is significantly reduced. Furthermore, with short disassembly times, an on-demand and simple replacement of, for example, a defective throttle module or the cancellation of the power influencing is possible, with replacement of further components, for example the control device, preferably not being necessary.

The electronic throttle module preferably has a first connection geometry for producing a signal connection with a complementary connection geometry of the cable harness and a second connection geometry for producing a signal connection with a complementary connection geometry of the control device. The connection geometry comprises connecting elements, such as contact pins and / or contact openings, for forming the signal connection. Due to the selected connection geometries, the throttle module can be electrically connected to form the formation of two interfaces with the wiring harness and the control device.

Preferably, the first connection geometry of the throttle module of the connection geometry of the control device correspond, preferably wherein the connection geometries are the same, more preferably identical, are formed. This allows a simple or fast signal connection of the throttle module with the wiring harness, which is formed due to its connection geometry per se for signal connection with the control device. So it is not an adapter o. The like. Required to connect the throttle module to the wiring harness, which simplifies the assembly and reduces the number of components for implementing the throttle module or the throttle function.

Alternatively or additionally, the second connection geometry of the throttle module correspond to the connection geometry of the cable harness, preferably wherein the connection geometries are the same, more preferably identical, are formed. In this way, a fast or simple signal connection between the throttle module and the control device is made possible, which is formed on the basis of their connection geometry per se for signal connection to the wiring harness. It is therefore again no adapter o. The like. Required to connect the throttle module with the control device, which simplifies the assembly and further reduces the number of components to achieve the throttle function.

According to the invention, it is particularly expedient if a first connector is provided on the throttle module, which has the first connection geometry and, preferably, for producing an electrical plug-in and / or latching connection designed for signal transmission with a complementary plug connector on the cable harness. Similarly, it is possible and advantageous if a second connector is provided, which has the second connection geometry and, preferably, is designed to produce an electrical plug-in connection and / or latching connection with a complementary plug connector to the control device. By inventively provided (s) plug or locking connection (s) a safe and easy to produce signal connection is made possible. In particular, the interconnected plug-in connectors are designed or positioned relative to one another and / or latched so that a secure signal transmission between the wiring harness and the throttle module is always ensured, especially under the action of a tensile force.

As far as the basic structure of the throttle module according to the invention is concerned, a multi-part design is preferred. In this case, a base body may be provided in which preferably all required for power limitation electrical or electronic components are provided or integrated. The main body can have connectors on opposite sides for connecting the throttle module to the cable harness on the one hand and to the control device on the other hand. The connectors are used only for the production of electrical connections. In this case, the first connector and / or the second connector may be fixedly connected to the base body, wherein preferably each one capable of signal transmission, preferably cohesive, connection, in particular solder connection, is provided between the connectors and the base body. In principle, the connectors can also be non-destructively detachably connected to the base body, in particular via a latching and / or clamping and / or screw connection.

With regard to cost-effective production of the main body and / or the first connector and / or second connector made of plastic, and, preferably, be designed as an injection molded component.

In order to ensure a clear identification or signaling of the main body, the main body may have a deviating from the first connector and / or the second connector color, in particular a signal color. In this way, the body lifts off from the connectors and is easily detected in the vehicle, whereby the findability of the throttle module is improved.

In addition, the base body and the connectors may optionally consist of other materials to meet the different requirements for electronics housings and connectors.

Another aspect of the present invention, which may also be implemented independently of the aspects described above, relates to a flow member for insertion into an intake port of an air intake nozzle of an internal combustion engine of a saddle-type powered vehicle, particularly a motorcycle, for power limitation or power reduction of the internal combustion engine by a limited or reduced air supply via the air intake, wherein the flow element is inserted into a receiving area on the air intake side of the air intake and held in the receiving area in the suction direction and wherein a reduction of the clear flow cross-section of the receiving area is effected by the flow element. The arrangement according to the invention accordingly has an air intake and at least one flow element of the type described above.

By the flow element, a reduction of the clear flow cross-section of the intake passage is effected. In this way, in particular in addition to the above-mentioned electrical throttle module, another convenient and simple and cost-effective way to reduce the power output of the engine created. In particular, the direct insertion of the flow element into the intake duct of the air intake allows a quick and / or easy installation and / or removal.

For insertion of the flow element, the air intake has at least one receiving area, in which the flow element can be manually pressed. It is then possible to glue the flow element as needed in the receiving area. Due to its dimensioning and elastic properties of the material of the air intake nozzle, however, the receiving region is preferably such that the flow element is held positively and non-positively in the receiving region.

With regard to an expedient embodiment of the flow element, a plate-shaped or platelet-shaped design is preferred, wherein the flow element may have a preferably central flow opening for the sucked-in air flow. This allows a simple production, in particular wherein the reduction of the flow cross-section is selectively adjustable by the choice of the flow diameter of the flow opening.

The flow element may be made of metal to ensure a sufficiently high dimensional stability for introducing the flow element in the receiving area.

So that the flow element is securely held in the intake passage, at least one axial stop, for example a projection or a material protuberance or also a bead, on the inside of the air intake port can limit the receiving area in the intake direction. This ensures that the flow element is not inadvertently pressed too far into the intake channel during assembly.

The flow element may be reversibly (non-destructive) releasably inserted into the receiving area, which simplifies a subsequent removal of the flow element from the intake passage. But it can also be glued.

If the flow element is designed as a flat component, then it is expedient for the flow element with the flat sides to be inserted transversely to the suction direction into the receiving region.

Preferably, the air intake on a Luftansaugseite a preferably circumferentially closed receiving area for insertion of the flow element in the intake channel, the flow element sealing edge, preferably over its entire outer circumference, used in the receiving area and / or can be festsetzbar. This allows an effective reduction of the clear cross section through the flow element, wherein the air supply preferably takes place exclusively via the flow opening.

In particular, the flow element can be used sealingly over the entire outer circumference in the receiving area. In this context, it may be advantageous if the flow element is designed in the manner of an annular part and / or at least partially has a round outer contour.

For a secure hold of the flow element in the receiving area, the flow element may be recessed in the intake channel with respect to an outer edge of the air intake nozzle in the intake direction. The flow element is therefore in any case not over the outer edge with its flat outer side and is preferably lowered in relation to the outer edge in the intake passage.

According to a preferred embodiment of the arrangement according to the invention two identical flow elements are provided, each flow element is assigned a separate receiving area for insertion into the intake duct of the air intake. The receiving areas are preferably at least partially separated transversely from and / or in the intake direction by a partition wall of the intake. By means of a plurality of receiving regions, it is possible to narrow the clear flow cross-section of the intake duct more or less, if necessary, by using one or more flow elements. In this case, preferably only one flow element is provided for each receiving area. In this context, it is particularly preferred if the flow elements are in the installed state in a same plane transverse to the suction direction of the air flow.

Another aspect of the present invention relates to an internal combustion engine, in particular a gasoline engine, for a saddle-type vehicle, in particular motorcycle, with an injection device for injecting a fuel into a sucked air flow, with a throttle valve for regulating the intake air flow and / or a fuel / Air mixture, with a combustion chamber, and with a system and / or with an arrangement in each case in the manner described above. Preferably, the internal combustion engine can have both an arrangement and a system of the type mentioned in each case. In this way, the possibility is created, the type-related performance limitation by two independently acting measures - namely the electrical or electronic throttle module on the one hand and the flow element on the other - make.
