    • In internal combustion engines having direct injection, an injector injects fuel into the combustion chamber to form an ignitable fuel/air mixture with combustion air supplied separately, the mixture being ignitable by a spark plug. The fuel is injected in a conical pattern, and the electrodes are protected from wetting by fuel and from coking if they are located outside the lateral surface of the fuel cone produced by the injection nozzle. To introduce an ignitable mixture between the electrodes and to ensure optimum operating performance of the internal combustion engine by improving the combustion process, a combustion chamber is configured so that the fuel cone is injected in a free jet which is substantially completely unaffected by the combustion chamber perimeter, and the electrodes of the spark plug project into a fuel vortex emerging from the lateral surface during injection. Electrodes are provided at different spark positions relative to the lateral surface to which the positive potential of the ignition voltage may be applied alternately for ignition of the fuel vortices as a function of the operating point of the internal combustion engine.
    • 在具有直接喷射的内燃机中,喷射器将燃料喷射到燃烧室中以形成可单独供应的燃烧空气的可燃燃料/空气混合物,该混合物可被火花塞点燃。 燃料以锥形图案注入,并且如果电极位于由注射喷嘴产生的燃料锥体的侧表面之外,则电极被燃料和不被焦化保护。 为了在电极之间引入可点燃的混合物,并且通过改进燃烧过程来确保内燃机的最佳操作性能,燃烧室被配置成使得燃料锥体以基本完全不受燃烧室影响的自由射流注入 并且火花塞的电极在注射期间投射到从侧面出现的燃料涡流中。 电极设置在相对于侧表面的不同火花位置处,可以交替地施加点火电压的正电位以使燃料涡流点燃作为内燃机的工作点的函数。

    • The invention relates to a device (1) suitable for controlling a surface (8) of an object (7), notably with respect to raised areas on said surface (8). The device (1) comprises a light source (2, 3) for generating a light beam (5, 6) directed towards the surface as well as a light sensor (4) for detecting light scattered by a raised area on the surface (8). The light beam (5, 6) generated by the light source (2, 3) is configured so as to scan the surface (8) in such a way that the raised area on the surface scatters the light beam (5, 6). If there is no raised area the light beam (5, 6) undergoes ideally no, or else only slight, changes. The light sensor (4) is arranged in such a way that at least part of the scattered light can be detected. In this manner it is possible to detect, for example, impurities on uneven or structured surfaces.

    • A supercharged internal combustion engine has an exhaust gas turbocharger which includes an exhaust gas turbine and a compressor. The exhaust gas turbine and the compressor are connected to a turbocharger shaft and an appliance for the transmission of power for the purpose of a mechanical step-up drive capability for the exhaust gas turbocharger arranged between the turbocharger shaft and the crankshaft of the internal combustion engine. The appliance includes at least one step-up gear and a controllable hydrodynamic coupling for torque transmission arranged between the crankshaft and the turbocharger shaft. In order to configure the internal combustion engine in a simple and compact constructional manner in such a way that a better increase in torque of the internal combustion engine can be achieved in the lower rotational speed range by the mechanical step-up drive of the exhaust gas turbocharger and to achieve substantially shorter response times during transient operation of the internal combustion engine, the hydrodynamic coupling can be locked up by a mechanical or electro-mechanical clutch and is arranged between the step-up gear and the crankshaft of the internal combustion engine.

    • An apparatus for sealing shut-off devices located in gas or liquid transporting pipelines having a sealing arrangement, which seals the shut-off device against a casing, the sealing arrangement having a gasket engageable against the circumferential surface of the shut-off device, a seating ring supporting the gasket, two chambers which can be supplied in a controlled manner with a pressure medium, and a method by which the gasket can be raised from the circumferential surface and pressed against the circumferential surface. The sealing arrangement has a driving member positively connected to the seating ring and a displaceable intermediate piston located on the driving member. The first chamber is located between the driving member and the intermediate piston and when subject to the action of the controlled pressure, brings about a movement of the driving member in the gasket raising direction. A second chamber located between the intermediate piston and the casing, when subject to the action of the controlled pressure, brings about a movement of the intermediate piston in the pressing direction. Between the seating ring and the intermediate piston are positioned spring elements which are biased in the pressing direction.
