Definitions
- the invention relates to a method for heating a throttle valve assembly in an internal combustion engine according to the preamble of claim 1 and an intake manifold for an internal combustion engine according to the preamble of claim 6.
- throttle valves in intake manifolds of internal combustion engines ensure, it is known such suction pipes and / or to heat the throttle valve connector. This is particularly important under weather conditions in which it freezes over Throttle valve can come, so that the air supply is no longer controlled can be.
- To heat the suction pipe it is common to use it in the area the throttle body via a corresponding branch from To heat the vehicle's cooling water circuit.
- each Throttle valve arrangement are known, in each of which an electric motor Throttle valve controls, the electric motor and the throttle valve so are arranged that a heat transfer from the electric motor to Throttle body is possible in principle.
- the heat development of the However, the electric motor is so small that only a small heat transfer takes place.
- the object of the invention is to provide a simpler way of heating the Propose intake manifold in the area of the throttle valve.
- the Throttle valves controlled by electronically operated throttle valve systems heating for example due to the cooling circuit, is eliminated can.
- An electronic accelerator pedal is constructed in such a way that the accelerator pedal, that is actuated by the driver is assigned an encoder that has a corresponding electrical connection connected to an evaluation unit which is the target position of the throttle valve with the actual position of the throttle valve compares and also additional operating parameters of the internal combustion engine processed.
- the throttle valve opened or closed by an electric motor. Because a mechanical Connection between electric motor and throttle valve exists because the electric motor opens the throttle valve via a corresponding shaft or closes, the electric motor and throttle valve are in close proximity to each other arranged, for reasons of installation space alone.
- a corresponding power supply is proposed the electric motor to increase its power loss so that the Electric motor heats up due to the mechanical connection and the good thermal conductivity of the material in the area of the throttle valve Heating of the electric motor is passed on to the area of the intake manifold, that surrounds the throttle valve, the so-called throttle valve connector.
- the suction pipe usually consists of aluminum, which has good thermal conductivity properties, but also other materials can have sufficient thermal conductivity.
- the heating of the electric motor can be suitably by a pulse train be increased, the AC voltage with a frequency generated that is high enough to mechanically respond to the motor to prevent due to the inertia of the actuator.
- the thus supplied accordingly, electrical energy is not converted into mechanical energy, but implemented solely in thermal energy. At least they should Throttle "tremors" to an extent that the combustion process is not affected.
- the area of the intake manifold is the is to be heated, a temperature measurement is assigned, via which the power loss to be supplied to the electric motor can be regulated.
- the drive current for the electric motor the throttle valve via the position control of the throttle valve in such a way regulated that the throttle valve moves quickly between one Minimum opening angle and a maximum opening angle.
- This Stroke range in the desired throttle valve opening angle dimensioned such that no undesirable effects occur during engine operation.
- a significant advantage of the invention is that, in contrast to State of the art, the suction pipe does not heat up until if the internal combustion engine has been running for a while and accordingly the cooling water warms up to sufficient temperatures has, but this heating can occur immediately when the internal combustion engine is started, if necessary, even before starting the internal combustion engine be provided because the corresponding supply of electrical energy the electric motor can be made immediately and the heating going on very quickly.
- a throttle valve 12 is used Control the performance of the internal combustion engine by the effective cross section of the intake manifold 10 by pivoting the throttle valve around it Axis 14 is enlarged or reduced.
- the throttle valve swivels 12 instead of an electric motor 16, which is controlled by a control device 18 is controlled via corresponding lines 24.
- the control unit 18 information such as position of the throttle valve, operating parameters such as intake manifold vacuum, speed and other information supplied to to open or close the throttle valve 12 depending on this information conclude.
- control signals in the form of a pulse train supplied to the electric motor in addition to the control signals, wherein the frequency of the pulse train can be so high that the electric motor 16th can no longer react mechanically and accordingly the throttle valve 12 no longer opens or closes, no trembling movements Throttle valve 12 take place more.
- a pendulum or tremor with no negative impact on engine operation and combustion processes can lead to the desired effect.
- a temperature sensor 20 provided the temperature on the wall of the suction pipe 10 detected and passed on to the control unit 18 via a line 22.
- the Temperature sensor can also be used in a detection of temperature changing electrical quantities exist, so that a separate component is superfluous.
- the winding resistance of the electric motor can be used as a measure of the temperature.
- the contribution of engine temperature sensor and / or air temperature sensor is possible. In this way, a control loop can be achieved which heats up limited the electric motor 16 to the necessary extent.
