摘要:
Systems and methods presented herein provide for the processing of PostScript print jobs that are not DSC compliant. A single stream of a PostScript data is processed and divided into multiple streams (e.g., page objects), each comprising data operable to render an individual page. In one embodiment, a method includes receiving the PostScript data stream and identifying object tokens in the PostScript data stream. An object token is operable to generate a PostScript object or execute a PostScript operation. A portion of the object tokens may be operable to define page boundaries in the PostScript data stream. The method also includes analyzing the object tokens to parse the object tokens into a plurality of page objects, separating the page objects into a plurality of data paths, and parallel processing the page objects through the data paths to rasterize the PostScript data stream on a page by page basis.

The invention proposes a sliding door for cold stores, in particular deep-freeze stores, which ensures good sealing around the frame, the intention being to avoid damage when a vehicle drives through too quickly when the door is not in a fully open state. This is achieved according to the invention in that at least one door leaf of the cold-store sliding door has at least one rigid region and at least one flexible region.

An internal combustion engine with spark ignition and a piston that includes a substantially U-shaped asymmetrical piston depression with a depression floor that tapers towards an edge of the piston and that changes in a continuously rising manner into a depression wall, and an expanding squeezing chamber, the arrangement being adapted to promoting a swirling rather than a turbulent flow of injected fuel.

In a method for determining a power limiting value for an electric machine in a vehicle, the electric machine being assigned an energy storage device, an intermediate power value is calculated from a maximally allowable current of the energy storage device and an instantaneous voltage. A corrected intermediate power value is determined by adding at least one power loss to the intermediate power value. A first correction value is determined for reducing the absolute value of the corrected intermediate power value if an instantaneous power of the energy storage device is greater than the absolute value of the calculated intermediate power value. The power limiting value is determined by superimposing the first correction value on the corrected intermediate power value.

A method for operating an engine of a vehicle, the engine having a cylinder with at least a first and second valve, the method comprising during a first mode, operating with the first valve active and the second valve deactivated during a cycle of the cylinder, where during said first mode, the cylinder operates to allow at least air to enter the cylinder during an intake stroke, where the air is mixed with fuel and compressed to attain auto-ignition; and during a second mode, operating with the first and second valves active during a cycle of the cylinder, where during said second mode, cylinder operates to allow at least air to enter the cylinder, where the air is mixed with fuel and ignited via a spark from an ignition plug.
摘要:
In an internal combustion engine with spark ignition and one or more reciprocating pistons, with an ignition device positioned in a roof-shaped top face of the combustion chamber and at least one fuel delivery device for each cylinder for direct fuel delivery essentially in the direction of the ignition device, and with at least one intake port configured so as to generate a swirl movement, the piston exhibits an asymmetrically shaped piston recess whose walls are configured as arcuate flow guiding faces assisting the swirl movement of the cylinder charge. To obtain reliable ignition of the directly introduced fuel on the one hand and maximum liberty in designing the engine on the other hand, the proposal is put forward that the piston recess between opposite walls should essentially constitute an open channel of meander-shaped or S-shaped configuration in plan view, at least one end of the channel forming an inlet area into the recess, which starts at the piston rim.
摘要:
A device for introducing fuel into the combustion chamber of an internal combustion engine, includes a unit for fuel delivery and an injection valve for withdrawing compressed gas from the cylinder and injecting the gas together with the delivered fuel into the cylinder, and a mixing space in the front part of the valve for the purpose of gas storage, the injection valve being provided with a valve for control of the gas exchange between the combustion chamber and the mixing space in the front part of the valve. To obtain reproducible operating conditions and an optimum closing time (E.sub.0) for the injection valve, the mixing space is connected to one or more sensor elements for measuring the pressure and/or temperature of the mixing space, and that the valve is closed in dependence on the physical quantity measured by the at least one sensor element.
