Abstract: A fluid accumulator arrangement suitable for use with a compression ignition internal- combustion engine comprising a first storage volume, a second storage volume, and valve means fluidly connected between the first storage volume and the second storage volume. In one embodiment, the valve means is a three-way control valve wherein, in a first position, the first storage volume communicates with the second storage volume, in a second position the first storage volume is isolated from the second storage volume and, in a third position, one of the first or second storage volumes communicates with a low pressure drain. The arrangement may also include control means to operate the valve means in accordance with predetermined control strategies.
