Definitions
- the invention is therefore based on the object, the exhaust gas control device on a To further develop the internal combustion engine in such a way that flexible control of the flow cross-section the exhaust pipe depending on various operating parameters the internal combustion engine is possible.
- the exhaust gas control device according to the invention has compared to the known solutions the advantage that by means of a continuous adjustability of the actuator in of the exhaust pipe, the flow cross section of the exhaust pipe is free at all times is adjustable. It is particularly advantageous to actuate the continuously adjustable Actuator in the exhaust pipe by means of an operating parameter of the internal combustion engine processing electronic control unit.
- This electronic Control unit is preferably on sensors for detecting the position of an accelerator pedal, for detecting the throttle valve angle of a throttle valve in the Intake line of the internal combustion engine and for detecting a filling signal in the intake line connected to the internal combustion engine.
- the detection of the filling signal in the Intake line is preferably carried out by measuring the intake manifold pressure, can but alternatively also via other measuring methods, e.g. B. by means of a hot wire.
- other operating parameters in addition to the above-mentioned measured variables of the internal combustion engine to be supplied and for a control the actuator in the exhaust pipe. Determining the electrical Actuating signals for actuating the actuator in the exhaust pipe take place within of the electronic control unit as a function of determined operating parameters the internal combustion engine, these preferably in a corresponding Map are stored. It is particularly advantageous to control the Actuator in the exhaust pipe depending on the load point.
- the pressure in the exhaust pipe via a corresponding sensor also to be recorded continuously and supplied to the electronic control unit as a measured value. In this way it is through a targeted adjustment of the actuator in the exhaust pipe and thus a targeted adjustment of the controlled flow cross-section on the exhaust pipe possible to counteract pressure fluctuations in the exhaust system.
- the continuously adjustable actuator used in the exhaust pipe is more advantageous Formed as a throttle valve by means of a corresponding electrical
- the position of the actuator e.g. servomotor
- the Throttle valve in the exhaust pipe between a full closed position and a full opening position continuously adjustable.
- the full closed position of the Throttle valve in the exhaust pipe is lower, especially at operating points Load advantageous, the resulting small amount of exhaust gas via appropriate Leakage can flow out.
- the electrically actuated throttle valve is preferred arranged behind a main catalytic converter in the exhaust pipe. This has next to one flexible control of the processes in the exhaust pipe also the advantage that a longer Dwell time of exhaust gas in the main catalytic converter is adjustable.
- a major advantage of the exhaust gas control device according to the invention on an internal combustion engine is the possibility by a specific adjustment of the flow cross-section an internal exhaust gas recirculation in the exhaust pipe or its closing to enable the internal combustion engine. In doing so, this internal exhaust gas recirculation part of the exhaust gas volume through the controlled exhaust pipe to the combustion chamber Internal combustion engine supplied again via the exhaust valves and there causes the known advantageous effects of exhaust gas recirculation, particularly with regard to lowering of pollutant emissions and a reduction in fuel consumption Internal combustion engine.
- This Throttle valve 9 is actuated by an electric servomotor 11, which in turn is controlled by an electronic control unit 13 with which the electric servomotor 11 is connected via a control line 15.
- the electronic control unit 13 has a large number of input lines, the measured values via corresponding sensors Feed into the control unit 13 via current operating states of the internal combustion engine.
- first electrical line 17 for connection to a sensor for detecting the accelerator pedal position
- second electrical line 19 for connection to a sensor for detecting the throttle valve position in a suction line of the internal combustion engine
- third electrical line 21 for connection to a sensor for detecting the intake manifold pressure in the intake line
- fourth electrical line 23 for connection to a sensor 25 for Detection of the exhaust gas pressure provided in the exhaust pipe 3.
- the corresponding Sensors for detecting the accelerator pedal position, the throttle valve angle and the Intake pipe pressure in the intake line are sufficient from the prior art known.
- the pressure sensor 25 for detecting the exhaust gas pressure in the exhaust line 3 is inserted in the exhaust pipe 3 in the area of the pre-catalyst 5.
- the internal combustion engine described with the exhaust gas control device works in the following way.
- During the operation of the internal combustion engine are over the electrical lines 17, 19, 21, 23 current operating parameters of the internal combustion engine fed into the electronic control unit and stored there with the help of a Operating map in a corresponding control signal for the position of the throttle valve 9 processed in the exhaust pipe 3.
- This control signal is the electric servomotor 11 fed via the control line 15 and the electric servomotor 11 into a corresponding adjustment movement of the throttle valve 9 implemented.
- the throttle valve 9 is preferably with at least one stop, e.g. B. provided for the closed position, so that a corresponding control signal a corresponding adjustment position is assigned to the throttle valve 9. It is particularly advantageous for the throttle valve 9 in the exhaust pipe 3 as a function of the current load state on the internal combustion engine to control via the electronic control unit 13.
- the throttle valve 9 is the corresponding request of a driver who has the Detection of the throttle valve position in the intake line and in particular via the Detection of the accelerator pedal position is determined.
- the throttle valve 9 is actuated in the Exhaust pipe 3 in time before an adjustment of the throttle valve in the intake pipe Internal combustion engine. This is made possible by using a so-called e-gas, in which the adjustment movement of the accelerator pedal is recorded electronically and the adjustment the throttle valve in the intake line accordingly via an electric motor electronic control unit takes place. It is particularly advantageous to have the throttle valve 9 in the intake line 3 approximately by a factor of 10 before the throttle valve in the intake line to operate the internal combustion engine.
