  • Publication number: 20130025566
    Abstract: A method and apparatus for controlling an air input in a rotary engine, including selectively controlling inlet ports communicating with an internal combustion cavity of the engine, the ports located serially downstream of the exhaust port. The inlet ports are controlled to alter air intake at various engine operational stages, such as start up, idle, etc., to allow for varying operational requirements to be met. For example: when a power demand on the engine is lower than a predetermined threshold, control may be effected by opening a primary inlet port and closing a secondary inlet port; and, when the power demand exceeds the predetermined threshold, control may be effected by opening the primary inlet port and opening the secondary inlet port, the secondary inlet port being in communication with the exhaust port throughout portions of the engine revolution to purge exhaust gases.

  • Publication number: 20130028768
    Abstract: In one aspect, described is a rotary engine having a purge port located rearwardly of the inlet port and forwardly of the exhaust port along a direction of the revolutions of the rotor, the purge port being in communication with the exhaust port through each of the chambers along a respective portion of each revolution, and the inlet and outlet ports being relatively located such that a volumetric compression ratio of the engine is lower than a volumetric expansion ratio of the engine.

  • Publication number: 20130025565
    Abstract: A multi-rotor internal combustion engine has a plurality of rotary internal combustion units axially distributed along an engine axis. Each unit has a rotor mounted on an eccentric portion of the shaft inside a housing. The housings of adjacent rotary internal combustion units have different angular positions about the engine axis so as to angularly offset the housing from adjacent housings, which may provide for a more uniform temperature distribution around the housings and may also or instead allow optimising of the balancing of pressure induced side loads on the shaft of the rotors.

  • Patent number: 8272010
    Abstract: A television display system with a television display for displaying television services and internet information, and an input unit for providing a command, the television display system receiving a data stream containing a plurality of key files, each key file including executable data and a respective key image representing said executable data. The television display system includes a memory for continuously maintaining over a period at least one of the key files, a display section displaying upon occurrence of any of a number of preselected events, a key image stored in said memory, superposed on a displayed said television service, said key image upon activation executing said executable data included in the same key file. The system also includes a command section for executing content of the key file of the displayed respective image conditional upon a key command being provided by the input unit.

  • Patent number: 7775044
    Abstract: A compound cycle engine (10) comprises a compressor and a turbine section (14, 18), and at least one cycle topping device (16) providing an energy input to the turbine section (18). The compressor section (14) compresses the air according to a pressure ratio PRgt. The cycle topping device (16) further compresses the air according to a volumetric compression ratio Rvc, and wherein PRgt×Rvc are selected, according to one aspect of the invention, to provide a cycle which permit a more compact and lighter compound cycle engine to be provided.
