Abstract: A fuel injection valve assembly for supplying a preliminary injection of fuel of a constant amount regardless of engine speed before the main injection of fuel begins comprising a spring biased, fuel supply pressure responsive, preliminary injection piston for the preliminary injection, a fuel supply pressure responsive loading piston for controlling the main injection fuel flow and a needle valve, both of the latter being biased oppositely by a common spring. Separate supply ducts for the preliminary and main fuel injections and the arrangement of the valve surfaces on the loading piston and needle valve enable the loading piston to be held closed and the needle valve to be opened by the pressure imposed on the preliminary injection piston and remain open long enough for the preliminary injection piston to travel its full stroke before closing and before the needle valve is opened for the main injection.

Abstract: In an internal combustion engine employing manifold fuel injection, the air flow rate through the induction manifold controls the motions of a slide in a metering and distribution valve assembly. The slide, in turn, controls the effective metering valve apertures of several individual openings, each leading first to an equal pressure diaphragm valve and, hence, to individual fuel injection nozzles.The system includes a differential pressure control valve, which maintains a constant pressure difference across the metering valve apertures in the metering and distribution valve assembly. The differential pressure control valve may be in parallel or series connection with the several equal pressure diaphragm valves. The system also includes a pressure control valve, responsive to engine parameters, which adjusts the resetting force acting on the control slide in the metering and distribution valve assembly.

Abstract: A fuel supply system for internal combustion engines includes an air-flow measuring member located in the induction tube of the engine. The air-flow measuring member includes a lever which, when displaced, directly displaces a fuel metering control slide of a fuel metering valve assembly. This control slide is subjected to an opposing force exerted by pressurized fluid which may be fuel. The pressure of the control fluid is variable and is changed depending on temperature and on the composition of the exhaust gases. The temperature-dependent control of the fluid pressure is achieved by so disposing a bi-metallic spring in the pressure control valve that its changing force is added to the closing force of a primary control spring in the valve. A separate electric heater is provided to adapt the control process to the heating characteristics of the engine in a desired manner. The exhaust gas-dependent control of the fluid pressure is achieved by so disposing a secondary spring in the pressure control valve that its force is also added to the closing force of the primary control spring in the valve. The compression of the secondary spring may be altered by energizing an electromagnet under the control of the amplified signal from an exhaust gas monitor probe.

Abstract: What follows is the description of a two-circuit braking system for motor vehicles having a wheel lock-prevention device. Each circuit includes magnetic valves, while the system includes a switching valve and bypass line structure connecting at least one of the two circuits to the switching valve. The switching valve is associated with a threshold value such that the switching valve is switched in dependence on the threshold value causing the bypass line structure to be placed into open communication with its respective circuit. In such a situation at least some of the magnetic valves are rendered ineffective so that a braking pressure increase without lock-prevention is achieved.

Abstract: A fuel injection device of for internal combustion engines, particularly a unit fuel injector, having a pump piston preferably driven via a drive cam and having a free piston hydraulically driven by the pump piston, the free piston divides a pump chamber from a pressure chamber, from which a pressure line leads to an injection nozzle of the engine. Via a magnetic valve, the fuel to be injected is first metered into the pressure chamber during the intake stroke of the pump piston and subsequently, in the control stroke, an injection quantity determining the supply onset is metered into the pump chamber. The pump piston with spaced annular grooves serves as a reversal device. During the metering stroke, a maintenance pressure that is lower than the metering pressure of the fuel and is generated via a pressure control valve is maintained in the pump chamber.

Abstract: A piston-type internal combustion engine is proposed which has externally-supplied ignition and in which fuel is injected, from the direction of the intake tube, past the opened inlet valve directed into a partial combustion chamber of disc-like embodiment, the bottom or top of which is defined, respectively, by the surface area of the piston substantially by the valve plate of the inlet valve. As the result of the injection of the fuel in the last portion of the intake stroke and the spin formation in the compressed charge with the aid of guided squeeze flows, a layering of the charge is attained, which improves the ignitability and the speed of complete combustion of the operational mixture introduced into the combustion chamber, with low intake and transfer losses.

Abstract: The present invention relates to a fuel injection system designed to supply fuel to a mixture compressing externally ignited internal combustion engine. The fuel injection system comprises an air metering member which is displaceable in a suction tube in accordance with the air flow rate and which displaces the movable part of a fuel metering valve in opposition to a resetting force which is produced by fuel operative in a pressure chamber into which projects an effective face of the movable part of the metering valve. The fuel is metered at the fuel metering valve under a specific pressure difference determined by the regulating valve means, the regulating valve means being influenced by the pressure in a control pressure line in which the pressure chamber is also disposed. Enrichment of the fuel-air mixture is obtained by varying the pressure difference of at least a first throttle by means of an electromagnetic valve disposed in the control pressure line and controllable of a function of the operating parameters of the internal combustion engine.
