    摘要: An apparatus for injecting fuel into the combustion chamber of an internal combustion engine, having an injection nozzle and following the injection nozzle a partition (12, 23, 29) which is provided with through openings (13) for the injection streams and is embodied as a guide device for a partial flow of combustion air, which flow is accelerated by the injector action of the fuel streams in the through openings (13). A device (26, 24, 32) for preheating the partial flow of combustion air is also secured to the partition (12, 23, 29). In this apparatus, the partial flow of combustion air circulates virtually continuously through the partition (12, 23, 29) embodied as a guide device, and the acceleration caused by the injector action of the fuel streams increases with increasing engine rpm. This has the advantage that over the entire power and rpm range of the engine, a uniform course of combustion and a reduction of toxic emissions is attainable.

    摘要: An apparatus for injecting fuel into combustion chambers, in particular of self-igniting internal combustion engines, is proposed, in which a fuel injection nozzle generates an aimed fuel spray and in which an air guide device and a heating device are provided. The fuel being injected is accompanied by an air flow which passes the heating device. The heating device has at least two heating elements of different effectiveness, of which at least one element serves for rapid heating and the other element is provided for continuous use.

    摘要: An apparatus for the injection of fuel into combustion chambers, in particular of self-igniting internal combustion engines, having an injection nozzle (10) and a subsequent glow body (20), which has a conduit (30) surrounded by heatable walls (26) and serving for the passage therethrough of the injected streams. At least one lateral opening (32) discharges into this conduit (30), the opening preferably communicating with a region (46) of the combustion chamber (36) remote from the core region of the ignition. The air aspirated through the lateral opening (32) warms up and enters into the peripheral zone of the injected streams, where the result is an air-fuel ratio and temperature conditions which are very favorable for ignition. Less heat energy is required to initiate the ignition than in the known apparatus of this general type. By eliminating the conventional glow plugs, which interrupt the movement of air in the combustion chambers, increased power is attained and the emission of soot is reduced sharply.

    摘要: A system for injecting fuel into the combustion chambers of an internal combustion engine, comprising an injection nozzle and a glow coil which is connected downstream and is enclosed by a sleeve. The sleeve contacts one end of the glow coil on the combustion chamber side and is connected with a current lead. The other end of the glow coil is grounded via a contact ring body, a heat protecting ring and the nozzle body of the injection mozzle. This arrangement has the advantage that an insulation of the contact ring body relative to the heat protection ring is dispensed with and the latter can be supported immediately at the contact ring body.

    摘要: A spark plug for internal combustion engines comprises a center electrode enclosed in an insulating body enclosed in a metal housing, and a ground electrode. The insulating body has an end portion which faces the combustion chamber. An electrical field develops, resulting in a surface spark gap between two electrodes on the surface of the insulating body at the end portion thereof. The insulating body is transversely divided into the upper portion and the lower portion, of which the lower portion facing the combustion chamber is made of a material having dielectric constant 5-50 times higher than that of the upper portion.

    摘要: To provide for improved cleaning of an optical combustion sensor, particularly to determine knocking in an internal combustion (IC) engine, a pick-up element made of glass, glass-coated or covered metal or the like, and, for example, hollow inside and filled with a vaporizable and condensable medium to define a heat pipe, has a sensing end portion which is formed with a mushroom-shaped enlarged head (14). The unit may be combined with the functions of a spark plug by extending a conductor therethrough, making the pick-up of electrically conductive glass or ceramic, placing a metal foil or other conductor at the outside, separated from the metallic housing by an insulating sleeve or the like.
