Definitions
- the invention relates to a throttle device for a Internal combustion engine according to the preamble of claim 1. It is already a throttle device for an internal combustion engine known (GB-A-2 245 932), which has a housing with at least one in a throttle body of the housing throttle body rotatably housed. Furthermore, is over the throttle organ is guided around a bypass duct, the Cross section of an idle actuator is changeable. The Throttle body and the idle actuator are in one shared housing. An electronic one Control device that provided electrical signals from Can evaluate sensors in order based on the evaluation e.g. B. appropriate control of the idle actuator to be able to make is not available.
- EP-A-596 392 is also a Throttle device known, the one in a housing of Throttle body arranged electronic Control unit shows that in connection with a Throttle valve actuator and one Throttle valve angle encoder is. But it is not Bypass channel formed in the throttle body, and it is also no regeneration valve in or on the throttle valve connector provided, which in turn electrical connecting lines from the control unit to the regeneration valve.
- a compact and in particular pre-testable unit that an electronic control unit, an idle actuator and therefore, there is no regeneration valve.
- the Throttle device has a throttle body in the form of a Throttle valve that rotates in a throttle body is housed. Furthermore, the throttle device a bypass channel, the cross section of one Idle controller changeable for the purpose of idle control is. In addition, the throttle is upstream Temperature sensor provided, which the temperature of the Throttle valve connector measures flowing air.
- the Throttle device is attached to an air distributor, that in the area of a cylinder head of the internal combustion engine is provided to the metered by the throttle valve Air through individual suction pipes to individual combustion chambers of the Distribute internal combustion engine. There is a in the air distributor Pressure sensor housed, the air pressure in the Air distributor measures.
- Modern engine control systems require a variety of Information about important company sizes of the Internal combustion engine provided by sensors and for Evaluation of an electronic control unit in the form electrical signals are supplied.
- the electronic Control unit calculates corresponding ones based on the sensor signals Control signals for the actuators of the engine control, such as for example for the ignition or for the Mixture preparation.
- An important factor is the Air mass drawn in by the internal combustion engine. It is known, for example from the rotational position of the Throttle valve and the associated speed of the Determine internal combustion engine.
- this method is relatively imprecise, so air mass meters are used, the upstream of the throttle valve by means of a heated temperature-dependent measuring element in the form of a hot wire or a hot film the air mass in the throttle valve assembly determine.
- Such air mass meters are, however relatively expensive.
- Another way to get around with relatively high accuracy the air mass sucked in by the internal combustion engine determine consists of this indirectly from the density of the Air in the throttle body and from the associated Stroke volume of the individual pistons of the internal combustion engine determine.
- the density of the intake air can be determined from the Calculate the state variables of temperature and pressure of the air, what in the prior art mentioned at the beginning Temperature sensor and a pressure sensor is provided. in the However, there is an idle range of the internal combustion engine relatively low flow velocity in the Throttle body so that the intake air relatively long in the throttle valve neck and the for example subsequent air distributor.
- An engine control system takes over the air mass that is sucked in also the control of a regeneration valve, part of a Fuel Evaporation Restraint System One Fuel tanks of the internal combustion engine is.
- the engine control system requires other information about the current position of the Throttle valve, for which a rotary encoder for example in Shape of a precision potentiometer on one Throttle valve shaft of the throttle valve is provided.
- the electronic control unit, the regeneration valve, the Idle actuator, the temperature sensor and the pressure sensor are relatively far apart in individual housings housed away.
- the electronic control unit is usually located in the engine compartment or in the Passenger compartment of a motor vehicle.
- the idler, that Regeneration valve, the temperature sensor and the pressure sensor are provided in the area of the throttle body, so that to connect especially with the electronic Control unit a variety of electrical connection lines and plug connections are required.

- the throttle device according to the invention for a Internal combustion engine with the characteristic features of the Claim 1 has the advantage that a compact Component is created that is inexpensive to manufacture and especially as pre-fabricated and pre-tested Unit in a simple manner on the motor vehicle can be grown. This advantageously results from the Elimination of the otherwise usual individual housings and their electrical connecting cables and plug connections further cost savings and simplified assembly in the Mass production. In addition, due to the reduced number electrical connecting cables and plug connections Operational safety and reliability of the Throttle device increased. The placement of a Regeneration valve in one around the throttle valve bypass channel allows a special compact design of the invention Throttling device.
- a temperature sensor and for example, a pressure sensor in the bypass channel has the Advantage that especially during the critical Idle phase of the internal combustion engine a precise determination of the air mass flowing in the throttle valve body possible is.
