Patent DE-19830575-A1 (DE)
Inventor: UITENBROEK PAUL
IPC: F02B43/00
Filed: 1998-07-08
Abstract: The invention relates to a charge control device for a reciprocating internal combustion engine, especially a gas engine. Said internal combustion engine contains at least one cylinder (4) wherein a piston (6) operates, said piston (6) being connected to a crankshaft (10). The cylinder has at least one intake opening (16) wherein an admission valve (18) operates. Said admission valve (18) opens and closes according to the rotation of the crankshaft, temporarily connecting the cylinder to an intake port (14) which terminates in the intake opening. The cylinder also has at least one exhaust opening (20) wherein an exhaust valve (24) operates. Said exhaust valve (24) opens and closes according to the rotation of the crankshaft, temporarily connecting the cylinder to an exhaust port (22) which begins at the exhaust opening. The invention is characterised in that a rotary-disc valve (28, 60, 62) is situated in the intake port (14), said rotary-disc valve being actuated by an electromotor (28; 90) and in that a control device (26) is provided. This control device controls the electromotor in dependence on at least one power requirement mechanism (34) in such a way that when the power requirement is decreasing, the time at which the rotary-disc valve closes increasingly precedes the time at which the admission valve closes.

Filed: 1999-07-26
Abstract: The invention relates to a method and a communication system for managing a packet service having a packet-based core network (CNW) and an access network (ANW). According to the invention, transmission of multimedia data in the packet data can be controlled by means of control nodes (EN) disposed on an interface between the core network (CNW) and the access network (ANW) and integrated into the data transmission from and to the mobile communication device (MS) via the air interface of the access network. The advantage of the invention resides in the fact that it is possible to actively intervene in the signaling of multimedia data tansmission as packet data through the control nodes, taht is, said signaling is no longer effected transparently for the mobile communication device. One additional advantage is that by integrating the control of multimedia data transmissiom, the data flows can be better adapted to the radio resources and/or the requirements of the mobile communication device.
