  • Patent number: 7513239
    Abstract: A method for operating an internal combustion engine, injects fuel directly into a combustion chamber as a main injection, a postinjection and optionally also as a preinjection. An injection nozzle with a plurality of injection bores effects the preinjection and the postinjection preferably which is carried out cyclically. To minimize wetting of the combustion chamber walls, during the postinjection the partial quantities of fuel and a lift of the nozzle needle of the injection nozzle are set so that, for each partial quantity of the postinjection injected into the combustion chamber, the reach of the respective fuel jet in the combustion chamber is limited and the reach is less than the distance to a combustion chamber boundary.

  • Publication number: 20080160729
    Abstract: Resist masks exposed to high-dose implantation processes may be efficiently removed on the basis of a combination of a plasma-based etch process and a wet chemical etch recipe, wherein both etch steps may include a highly selective etch chemistry in order to minimize substrate material loss and thus dopant loss in sophisticated semiconductor devices. The first plasma-based etch step may provide under-etched areas of the resist mask, which may then be efficiently removed on the basis of the wet chemical etch process.

  • Patent number: 7225791
    Abstract: The invention relates to an internal combustion engine with a fuel injection device with an injection nozzle having a nozzle needle and a plurality of injection bores. The injection nozzle is arranged to inject fuel into the combustion space in the form of a plurality of fuel jets as a main injection, as a post-injection and/or a preinjection. The injection bores of the injection nozzle are arranged in at least two different separately activatable rows of holes, an operating stroke of the nozzle needle being set by control unit as a function of a piston position and/or an operating point of the engine, and the rows of holes of the injection nozzle different injection-hole cone angles.

  • Patent number: 7185832
    Abstract: In an injection nozzle for an internal combustion engine including a nozzle housing, a closure member disposed in a nozzle opening and connected to a nozzle needle for axially moving the closure member outwardly off its seat in the nozzle opening to open the nozzle by providing a gap to permit fuel to be discharged into a combustion chamber of an internal combustion engine so as to form a fuel injection cone, the nozzle seal and the closure member have seal surface areas provided with turbulence chambers for imparting turbulence to the fuel flowing through the gap in order to more finely atomize the fuel forming the fuel cone in the combustion chamber.

  • Patent number: 7059295
    Abstract: A method is provided for operating an internal combustion piston engine, in which fuel is injected directly into a working chamber in the form of a pre-injection and main injection by means of an injection nozzle with a plurality of injection holes. The pre-injection takes place in a clocked manner. In order to minimize the moistening of the walls of the combustion chamber, a higher fuel pressure prevails in an injection device during the main injection than during the pre-injection. Furthermore, optimum homogenization of the pre-injected quantity of fuel is obtained by restricting the range of the injected fuel jets while simultaneously maximizing the atomization of the fuel particles and reinforcing the disintegration of the fuel jets during the clocked pre-injection.

  • Patent number: 6949399
    Abstract: When changing a dopant species in an implantation tool, typically a clean process is performed to reduce cross-contamination, which is considered a major issue in implant cycles applied in advanced CMOS processes. Especially, the employment of an implanter previously used for heavy ions may generate increased cross-contamination when subsequently used for boron or phosphorus implants at moderate energies. A clean implant process using xenon gas may effectively reduce this cross-contamination at shorter process times compared to a conventional argon clean step.

  • Patent number: 6897114
    Abstract: In manufacturing a recessed gate transistor, a channel implantation and a source/drain implantation are performed by means of a single implantation mask prior to the formation of a gate opening. Thereafter, the gate opening is formed to a depth that extends substantially to the channel implant so that raised drain and source regions are created which are substantially even with the gate electrode formed in the gate opening. Consequently, expensive and complex epitaxial growth steps can be avoided.
