Definitions
- the invention relates to a fuel metering device according to the preamble of claim 1.
- Fuel metering devices of this type are usually used as membrane gasifiers for internal combustion engines.
- a diaphragm carburettor a movable diaphragm is displaced by a negative pressure which arises during the intake process in an intake duct or a crank chamber, as a result of which a fuel lock is opened and fresh fuel can flow into a fuel chamber.
- the fuel flows into the intake tract via control devices and nozzles known per se, where it is mixed with air that is also flowing in and is finally fed into a combustion chamber as a fuel / air mixture.
- the deflection of the membrane determines the amount of fuel delivered in each case.
- the engine speed and the quantity of fuel supplied are roughly in proportion, since at high engine speed a lot of fuel is drawn in per unit of time, while less fuel flows at low engine speed and a correspondingly reduced number of strokes.
- a fuel metering device in which the position and / or the mobility of the z. B. can be influenced by a membrane formed by an active actuator whose control is coupled to an ignition device of an internal combustion engine. In this way, if an ignition pulse is omitted, an unnecessary supply of fuel into the intake tract of the internal combustion engine can be reduced or even completely prevented.
- the stoichiometrically correct composition of the fuel-air mixture is an important prerequisite for complete combustion, optimal engine performance and favorable exhaust gas behavior of the engine.
- the concentration of oxygen per volume of air is generally dependent on the altitude at which an internal combustion engine is used Use comes, whereby the oxygen concentration decreases at higher altitudes. Accordingly, the performance of the internal combustion engine when used at higher altitudes is reduced by the reduced oxygen concentration and a consequent deviation from the stoichiometrically correct composition of the fuel / air mixture. This makes a new adjustment of the carburetor necessary to adapt to the changed operating height in order to restore the optimal fuel-air ratio to be supplied to the internal combustion engine.
- the invention has for its object to provide a fuel metering device with which internal combustion engines can be operated automatically adapted to different heights.
- a fuel metering device has a fuel chamber, an openable and closable fuel inlet to the fuel chamber and at least one fuel outlet from the fuel chamber to an intake duct of an internal combustion engine, part of a wall of the fuel chamber consisting of a first one, depending on a pressure difference exists between a pressure in the fuel chamber and an ambient air pressure movable element, which is coupled to a closing element for opening and closing the fuel inlet, and wherein an amount of fuel that is to be supplied to the intake duct for a predetermined operating position of the internal combustion engine is adjustable depending on the ambient air pressure.
- a major advantage of the fuel metering device is that the variability of the composition of air is automatically compensated for by a corresponding amount of fuel, depending on a corresponding height, so that the internal combustion engine is always supplied with only as much fuel as for a stoichiometrically correct one Burning is required.

- the biasing force may be based on a magnetic interaction.
- a second element in contrast to the first movable element, a second element can be arranged which is movable as a function of a change in the ambient air pressure and in the direction of the first movable element.
- first and second magnetic parts are attached to both the first movable element and the second movable element, the second movable element being attached to the first movable part is approximated such that a magnetic interaction between the first magnetic part and the second magnetic part is increased, as a result of which the first movable part can be set in motion for actuating the closing element.
- the main advantage of the above-mentioned embodiment is that when the ambient air pressure decreases, only due to the mobility of the second movable element does the second magnetic part attached to it move in the direction of the first movable element or the first magnetic part attached to it and move thereby reducing the distance between the two magnetic parts. As a result, an interaction between the magnets increases, which leads to the first magnetic part being attracted more by the second magnetic part. This changes the position of the first movable element, as a result of which the closing element coupled to the first movable element narrows the fuel inlet in such a way that the amount of fuel flowing through the fuel chamber is reduced in order to adapt the stoichiometric ratio to the changed use height.
- the pressure detection device can have the chamber, and the control device can also have the second movable element.
- the second movable element can hermetically seal a chamber, an intermediate space being provided between the first movable element and the second movable element, which is open to the environment.
- the actuating device has an active actuator by means of which the prestressing force can be generated.
- a first magnetic part can be attached to the first movable element, while the actuator can be formed from an electromagnet that is opposite the first magnetic part, and wherein a current flowing through the electromagnets is proportional to the ambient air pressure.
- the actuator can be electrically connected to a map control which adjusts the current flowing through the electromagnet as a function of the ambient air pressure.
- the map control z. B. output an analog or digital electromagnetic signal with which, based on the measured ambient air pressure, a suitable flow of the electromagnet and thus the stoichiometric composition of the fuel-air mixture appropriate to the air pressure and the load case can be set.
- All of the above-mentioned possible embodiments of the fuel metering device according to the invention have the advantage that the amount of fuel that is to be supplied to the intake duct for operating the internal combustion engine can be automatically set to a smaller value when the ambient air pressure decreases, in order for the fuel air Mixture to ensure a stoichiometrically correct composition, taking into account the prevailing oxygen concentration.
