摘要： A launch control method for a continuously variable transmission (CVT) is provided, where the CVT comprises a hydro-mechanical variator, a summing transmission connected to an output side of the variator, and a clutch for selectively connecting the summing transmission to an output member. The method determines whether a launch has been requested, and adjusts a variable displacement pump of the variator to a predetermined fixed displacement. Engagement of the clutch is commenced, and the method then determines whether a predetermined degree of slip exists between input and output elements of the clutch. The clutch is held at its present state of engagement when the predetermined degree of slip has been established, and the variator is placed into a torque control mode. The method then determines when there is zero slip between the input and output elements of the clutch, and then instructs full engagement of the clutch. The method then holds the pump of the variator at its current displacement until a predetermined time period has elapsed, before reverting to a standard transmission control algorithm. A CVT is also provided.

摘要： An apparatus for detecting urea deposits in an exhaust pipe of an internal combustion engine is provided, where the urea is introduced into the exhaust pipe in an aqueous urea solution via a nozzle. The apparatus comprises at least one radiation receiver which, in use, is located within the exhaust pipe downstream of the nozzle. The apparatus further comprises an electronic control unit in communication with the receiver, wherein the receiver communicates radiation data to the control unit which allows the control unit to establish whether deposits have formed within the exhaust pipe. A control valve is also provided which controls flow of the solution to the nozzle in response to signals from the control unit. A method of detecting urea deposits in an exhaust pipe of an internal combustion engine is also provided, as in an automotive vehicle incorporating the aforementioned apparatus.

A variator has an input side connected to the input shaft, and an output side. The variator is adjustable so as to vary a transmission ratio between the input and output sides. A differential transmission has a first differential input element connected to the input shaft, a second differential input element connected to the output side of the variator, and first and second differential output elements. A range transmission has a first range input element, and at least one range output element connected to the output shaft. A first connecting component selectively connects the first differential output element to the first range input element. A second connecting component selectively connects the second differential output element to the first range input element. The first and second connecting components are located in a connecting space defined between the differential and range transmissions. A vehicle incorporating this CVT, and a method of operating the CVT are also provided.

摘要： A control process for controlling an engine speed governor of an engine is provided. The process comprises the steps of calculating the current engine power being developed by the engine, and determining an appropriate engine speed for the current engine power based upon a first engine map. The process then instructs the speed governor to adjust the engine speed in accordance with the first map if required. The process monitors for desired engine power requests, and calculates a power ratio of desired engine power versus current engine power upon receiving a desired engine power request. The process then establishes an engine speed adjustment value based upon a second engine map of power ratio versus speed adjustment value, and instructs the speed governor to adjust the engine speed in accordance with the speed adjustment value. A speed governor system incorporating the control process, and a work machine or vehicle incorporating such a system are also provided.

摘要： A tire apparatus is provided, the apparatus including a tire body for attachment to a wheel rim to define a first inflatable volume. An inner chamber defines a second inflatable volume which is located within the first inflatable volume of the tire body. A first fluid communication path is provided between the first and second inflatable volumes and a second fluid communication path is provided between the first inflatable volume and the atmosphere. A first valve opens and closes the first fluid communication path, and a second valve opens and closes the second fluid communication path. The tensile strength and pressure-containing capacity of the material structure of the second inflatable volume is greater than that of the tire first inflatable volume. A first fluid pressure within the first inflatable volume of the tire body is optimisable by opening the first valve to allow pressure transfer from the second inflatable volume into the tire body, and/or opening the second valve to allow pressure to vent from the tire body to atmosphere. A vehicle wheel and active tire pressure control system incorporating the tire apparatus are also provided.

摘要： A method and system for sampling of airborne microbial activity is described. The system incorporates an air sampler configured to collect and process ambient air to create a liquid sample, the air sampler comprising an air inlet and a liquid outlet. A removable cassette comprising a plurality of vials, each vial dimensioned for receiving a volume of liquid, is also provided. A first vial of the plurality of vials is configured for receiving the liquid sample from the air sampler, at least one other vial of the plurality of vials comprising a reagent for a microbial assay and the system is configured to effect an introduction of at least a portion of the liquid sample into the at least one other vial to create a sample under test. The sample under test can be lysed, and then using a monitoring station it is possible to determine optical changes in the sample under test and to provide an output indicative of monitored optical changes.
