Abstract: In a fuel injection valve body for a direct injection type internal combustion engine, an entire nozzle body tip portion is formed in a conical shape protruding from a nozzle body outer peripheral surface covered with a cap. Therefore, neither a corner portion or a recessed portion is formed on a surface of the nozzle body tip portion. This prevents heat generated by combustion from concentrating at a corner portion or a surface area from enlarging by a recessed portion, which in turn prevents heat generated by combustion from increasing the temperature of the nozzle body tip portion. Moreover, since a foremost portion of a spherical shape is formed such that it does not form a corner portion or a recessed portion in a peripheral portion of a conical shape, heat generated by combustion does not increase the temperature of the nozzle body tip portion. The temperature of a nozzle hole can therefore be prevented from increasing and accumulation of deposits can be restricted.

Abstract: An electromagnetically activated valve possesses an electromagnetic circuit, formed by, among other things, a magnetic coil, a magnet housing, and a core which serves as the inner pole. A valve element which serves as the anchor and closing element is spherical in structure, and moves axially within the magnet housing. A contact element is arranged between the core and the valve element, and has a contact surface with a spherical curve, facing the valve element. The valve element is surrounded by a guide element at least in part in the circumference direction, which element has a guide opening which also has a spherical curve, at least in part. The valve, in the form of a fuel injection valve, is particularly suitable for use in fuel injection systems for mixture-compressing, outside-ignition internal combustion engines.

Abstract: An apparatus for injecting a fuel-air mixture for multi-cylinder internal combustion engines having an electromagnetically actuated fuel injection valve with a valve seat and valve member, and a distributor with an air feed and a number of distributor bores, corresponding to the number of engine cylinders, and communicating with the air feed. In order for there to be only an extremely slight variation in quantity of the fuel metered to the various distributor bores during the valve opening, while having a simple structure of the fuel injection valve, the valve member is carried by a valve needle that is axially displaceably guided in a valve chamber preceding the valve seat by means of a guide segment, the fuel being delivered to the valve chamber in a region between the valve seat and the guide segment.

Abstract: A device and method for injecting a fuel-gas mixture. The novel device has an advantage of a simple and exact adjustment of an annular gas gap. The adjustment of the axial extension of a narrow annular gap is effected by varying the axial spacing between the face end of a retaining shoulder on a fuel injection valve and the face end of the bottom part in the region of the annular gas gap of the gas enveloping bushing. The proposed device for injecting a fuel-gas mixture is especially suitable for injection into the intake tube of a mixture-compressing internal combustion engine with externally supply ignition.

Abstract: An electromagnetically actuatable valve is proposed, which serves in particular to inject into the intake tube a mixture-compressing internal combustion engines with externally-supplied ignition. The valve includes a flat armature which is firmly connected with a ball arranged to cooperate with a fixed valve seat. The flat armature is pivotably supported on its end remote from the valve seat on a spring tongue preferably embodied out of a remnant air disc. A tubular inflow stub is disposed concentrically to the valve axis, communicating on one end with a fuel distributor line and on the other end protruding as deeply as possible into the valve. A tubular outlet stub leading away from the valve seat is concentrically guided in the inlet stub, and arranged to have its end remote from the valve seat discharge into a fuel return flow line. As a result, a cooling of the valve and the return of heated fuel which contains vapor bubbles to its supply source is assured.

Abstract: An apparatus for the combined blow-injection of fuel and air for fuel injection systems of internal combustion engines having a housing with a fuel connection an air connection and a blow-injection opening communicating with the air and fuel connections. Two valves are disposed in the housing and simultaneously actuated by an electromagnet. Both valves are disposed concentrically with one another, directly at the blow-injection opening to make it possible for the mixing ratio to be determined solely by the opening duration of the valves by means of synchronously clocked metering of fuel and air. The valve seat of the air valve and the valve seat of the fuel valve are carried in common by a hollow shaft valve member actuated by the electromagnet. For valve opening, the valve member of the air valve lifts inwardly of the housing and the valve member of the fuel valve lifts outwardly, and a stroke stop is disposed in the stroke of the valve member of the fuel valve in such a way that the maximum stroke path of the hollow shaft valve member is longer than that of the valve member of the fuel valve.

Abstract: An air injector is provided in the vicinity of a fuel injector. By the fuel injector and the air injector, the droplet diameter of a gasoline spray included an air-fuel mixture supplied to a cylinder of the engine is controlled. When the fuel injector is operated during a suction stroke of a gasoline engine, the droplet diameter of the gasoline spray supplied to a portion if the cylinder in a vicinity of a discharge electrode of a spark plug is controlled to have a predetermined value, such as substantially 40 .mu.m. Since the droplet diameter of the gasoline spray is controlled voluntarily, the air-fuel mixture of the gasoline spray size having a good ignition characteristic property is distributed selectively in the vicinity of the discharge electrode of the spark plug. A stable ignition condition for the engine is maintained without the occurrence of knocking, and an engine having a high thermal efficiency is obtained.
