Abstract: An engine control system includes a power module, an air flow module, a torque estimation module, and an air control module. The power module determines a power-based torque based on a desired engine speed. The air flow module determines an air flow value based on the power-based torque. The torque estimation module estimates a desired torque based on the air flow value. The air control module selectively determines a throttle area based on the desired torque. A throttle valve is actuated based on the throttle area.

Abstract: A control system for an engine of a vehicle includes a requested torque module that determines a first requested torque based on an accelerator pedal position and a current engine torque output capacity. An accelerator effective position module determines an accelerator effective position based on a requested driver axle torque request signal. A power enrichment (PE) module enables a PE mode to provide a richer than stoichiometric fuel equivalence ratio based on the first requested torque and the accelerator effective position.

Abstract: An engine control system comprises a pedal torque determination module, a driver interpretation module, and an actuation module. The pedal torque determination module determines a zero pedal torque based on a desired engine torque at a zero accelerator pedal position and a minimum torque limit for an engine system. The driver interpretation module determines a driver pedal torque based on the zero pedal torque and an accelerator pedal position. The actuation module controls at least one of a throttle area, spark timing, and a fuel command based on the driver pedal torque.

Abstract: An engine control system includes a spark bound module that determines a bounded spark value based on a desired spark value, a torque bound module that determines a bounded torque value based on the bounded spark value and a desired torque value, and an inverse torque calculation module that determines a desired engine air value based on the bounded torque value and the square of the bounded spark value. The engine air value may be one of a desired air-per-cylinder value and a desired manifold air pressure value. The bounded spark value and the bounded torque value are determined based on one or more of a plurality of engine actuator positions. Related methods for determining the bounded spark value, the bounded torque value, and the engine air value are also provided.

Abstract: The present invention relates to a method and a device for treating the surface of objects, in particular strip material or deep-drawn material, in which the to-be-treated surface (2) of the object (1) is subjected to a barrier discharge which is generated between a first planar electrode (4) and a second planar electrode (5) in a discharge region (3) which is filled with a first gas or gas mixture, with a plasma-excited second gas or gas mixture which emits UV radiation being utilized as the second electrode (5).

Abstract: A device for the treatment of a flowing gas, such as an exhaust gas, includes at least one pair of smooth electrodes that are arranged opposite each other so that they form between them a discharge space through which a gas flows. For each pair of electrodes, at least one electrode is coated with a dielectric material on a side facing the discharge space. At least one electrode has one or more thickened areas facing the discharge space. The one or more thickened area has at least one opening through which the gas can flow. A device may be used in the cleaning of exhaust gases from internal combustion engines of motor vehicles as well as the cleaning of waste gases of power plants or waste incinerating plants.

Abstract: Process and device for operating an internal combustion engine with less pollutant emission, whose exhaust gas is subjected to an electrical aftertreatment during engine operation to convert pollutants, the emissions of which are measured. To improve a process with the features mentioned initially, so that on the one hand the desired reduction of emissions of the internal combustion engine is achieved during its entire time of operation, but on the other hand so that the design of the electrical system of the internal combustion engine does not have to be unreasonably large and thus costly, the electrical aftertreatment of the exhaust gas occurs only during the portion of the operating time during which emission peaks occur.

Abstract: A barrier discharge device (4a, 4b, 4c) installed in a vacuum chamber (1) consists essentially of at least two facing electrodes (20, 22); a dielectric (22) situated between the electrodes (20, 22) and in the immediate proximity of one of these electrodes (20); and a power source (26), which is connected electrically to the electrodes (20, 22). The plasma particles and UV radiation generated during the electrical discharge between the electrodes (20, 22) pass through the electrode (22), which is permeable to UV radiation and plasma particles, and thus emerge from the discharge space. On the surfaces (5a, 5b), the UV radiation induces a photochemical cleaning process, and the impinging plasma particles induce a plasma-chemical cleaning process. The cleaning process is essentially independent of pressure and can be used at pressures of up to 10 bars, which means that the cleaning process can be operated in particular during the time in which the vacuum chamber (1) is being pumped out.
