    Abstract: The present invention proposes a fuel-air mixture-forming device for internal combustion engines, having a rotationally symmetric nozzle body (2) which, together with a rotationally symmetric throttle body (8) displaceable in it, forms a convergent-divergent nozzle which discharges into a radial diffusor (6). In the vicinity of the narrowest cross section (5) of the nozzle there is provided a fuel slot (11) extending around it and discharging into it, at least one fuel feed line (9, 10) discharging into the fuel slot. The radial diffusor is formed by a region of the nozzle body which is curved outward in the direction of flow of the mixture and by a wall (15) of a structural member (17) which forms a structural unit (18) with an intake manifold (7) of the internal combustion engine, the wall (15) lying opposite the nozzle body and being rotationally symmetric to the longitudinal axis (1) of the throttle member and having a bulge (16) pointing toward the throttle member. Due to its development, the radial diffusor makes it possible that a film of fuel which necessarily adheres to the diffusor wall upon injection of the fuel detaches itself, whereby an improved mixture is formed.

    Abstract: In a fuel/air mixture preparation device for internal combustion engines, there is a nozzle body (2) of rotational symmetry having a throttle member (7) of rotational symmetry which is displaceable within the body, the body forming a convergent/divergent nozzle. With the throttle member (7), which is displaceable in the nozzle body, the main air-mass throughput through the nozzle is determined. At least one fuel feed line (8 and 9) enters into the nozzle body. The fuel feed line has a circumferential fuel slot (10) which is developed in the wall of the nozzle body as well as a circumferential fuel/air slot (12) which joins it and is open towards the inside in the nozzle body. At a transition place between the fuel slot and the fuel/air slot there debouches an air feed (13) which is approximately under ambient air pressure. From a gap opening (11) of the fuel/air slot, the fuel mixed with air is injected approximately transversely to the direction of the main air mass flow, into the inside of the nozzle body.

    Abstract: An electronic injection system for Otto engines with injection nozzle (4) has a displaceable throttle body disposed in the intake air flow (2), and includes intake air mass measurement. In order to assure optimal measurement and dosaging of the mass flow of air at minimum structural expense and within a minimum space, particularly in the case of rapidly varying engine loads and speeds of rotation, the injection system has a convergent/divergent nozzle (12) with narrowest cross section adjustable by the nozzle body. The system includes a position indicator (18) for the throttle body, measurement devices for the pressure p.sub.O in front of the nozzle, and the pressure p.sub.L at the narrowest point of the nozzle and the air temperature T.sub.O in front of the nozzle. Also included is an electronic controller device (19) operative with at least the input variables p.sub.O, p.sub.L, T.sub.O and position (x) of the throttle body to provide an output variable opening time t.sub.O of the injection nozzle.

    Abstract: A system with which a correction of the fuel composition upon a change in the state of load of an internal combustion engine with which a mixture-forming device (4, 6, 8, 9, 11) is associated is constructed in structurally simple manner. The mixture-forming device has a feed unit (6) for the fuel with an inlet-side fuel conveyor line (5) and a discharge-side fuel conveyor line (7) and a movably mounted feed member (18). Depending on the position of the feed member (18), the feed member (18) provides variable fuel passage cross-sections in the feed unit (6). The feed unit is connected via an opening (31) which is closed in sealing fashion by a movable equalization element (33), the equalization space (32) being connected via a branch line (34) to the discharge-side fuel conveyor line. The feed member and the equalization element are coupled with each other locked for movement in such a manner that a movement of the feed member in the direction of an enlarged fuel passage cross-section leads to a movement of the equalization element which reduces the equalization space. A movement of the feed member in the direction of a reduced fuel passage cross-section leads to a movement of the equalization element which enlarges the equalization space.
