Abstract: A method is described of controlling at least one operation in at least part of a lifecycle of a replaceable container which is arranged to be removably seated in a dock in a vehicle and which at least before seating in the dock contains an ancillary fluid for use by the vehicle. A controller communicates with a data carrier carried by the container, determines, on the basis of the communication with the data carrier, data associated with at least one of the container, its contents and the vehicle, and controls carrying out of at least one action in relation to at least one of the container and its contents on the basis of the data associated with at least one of the container, its contents and the vehicle.

Abstract: A method is described of supplying liquid to a liquid delivery system in a vehicle. A a replaceable liquid container including a reservoir containing liquid is releasably coupled in the vehicle to provide fluidic communication between the reservoir and a liquid delivery system of the vehicle during operation of the vehicle. The method includes the steps of : (i) prior to establishing liquid communication between the reservoir and the liquid delivery system of a selected vehicle, communicating with a data carrier carried by the container and determining data associated with at least one of the container and its contents; and(ii) using the data in an analysis of suitability of the container and/or content of the container for the selected vehicle and generating a suitability output, and(iii) establishing liquid communication between the reservoir and liquid delivery system of the selected vehicle in dependence on the suitability output.

Abstract: The present invention relates to a replaceable fluid container for an engine comprising: a first reservoir for holding a fluid; a second reservoir for holding a composition to be added to the fluid; a fluid coupling adapted to provide fluidic communication between the first reservoir and a fluid circulation system of the engine; and a dose controller to provide a dose of the composition into the fluid for circulation in a fluid circulation system of the engine.

Abstract: In some embodiments, there is provided a method of controlling a pressure gradient between a combustion chamber and a crankcase of an engine, the method having: receiving, at a control device, a signal indicating that a lubricant container is coupled to a lubricant circulation system associated with the engine, in response to the received signal, providing data to cause operation of a suction control device for facilitating control of the pressure gradient.
