In a method for simulating a printing process of print jobs in a digital high-capacity printing system with print server and printing apparatus having a plurality of modules: a simulation state of the printing apparatus is activated by (e.g. a user of) a monitoring module of the digital high-capacity printing system, a print job is started with print data at the print server by the monitoring module, the print data is transferred to the printing apparatus, printing is simulated by supplying unrastered print data to an image raster computer of the printing apparatus while data is withdrawn from the image raster computer, and feedback is provided to the monitoring module of the digital high-capacity printing system about the occurrence of an error message. The speed of the removal may correspond to the print speed.

Method for simulating a printing process of print jobs in a digital high-capacity printing system

An installation for controlling the charge-cycle of an internal combustion engine which includes an inlet valve and an exhaust valve as main control devices as well as a shutter arranged in the suction system as auxiliary control device. At low rotational speeds and at full load of the engine, the shutter is so controlled that it rapidly opens a cross section in the suction system during the end phase of a suction operation. An increased velocity of the fresh gas flow and a pressure wave prior to inlet-closure is achieved thereby which increases the cylinder fill. This high pressure level can be maintained in the suction system or in the manifold between the auxiliary control device and the main control device by premature closing of the auxiliary control device. A preferred embodiment includes a valve or flap symmetrically arranged on a rotating shaft which is drivingly connected with an electromagnetic rotary adjusting device that drives the valve or flap oscillatingly and/or rotatingly with very high angular accelerations and decelerations. A valve controlled according to a performance graph and driven by a motor may serve, in addition to an increase of the full load cylinder fill at low rotational speeds, also for the partial load control of the internal combustion engine.
