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.
A fluid accumulator arrangement suitable for use with a compression-ignition internal combustion engine, including a first storage volume, a second storage volume, a valve fluidly connecting the first storage volume and the second storage volume, and control module arranged to receive a signal indicative of an engine start event, in which circumstances the control module is operable to:
A fluid accumulator arrangement suitable for use with a compression-ignition internal combustion engine, including a first storage volume, a second storage volume, and a valve fluidly connecting the first storage volume and the second storage volume and being operable between a first position in which the first storage volume communicates with the second storage volume, and a second position in which the first storage volume is isolated from the second storage volume, and a control module arranged to monitor the pressure of fuel in the first storage volume and the second storage volume when the volumes are isolated from one another, and is configured to link the first storage volume to the second storage volume for a predetermined time period in circumstances where the pressure in the first storage volume exceeds the pressure in the second storage volume.
A fluid accumulator arrangement suitable for use with a compression-ignition internal combustion engine, including a first storage volume, a second storage volume, a valve fluidly connecting the first storage volume and the second storage volume, and a control module arranged to receive a signal indicative of the stability of an engine operating condition and being operable to control the valve in response to the signal.
A fluid accumulator arrangement suitable for use with a compression ignition internal-combustion engine comprising a first storage volume and a second storage volume, and a valve fluidly connected between the first storage volume and the second storage volume, wherein the valve is a three-way control valve and 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.
A fluid accumulator arrangement suitable for use with a compression ignition internal-combustion engine comprising a first storage volume (27) and a second storage volume, and a valve fluidly connected between the first storage volume and the second storage volume, wherein the valve is operable between first and second positions such that, in the first position, the first storage volume communicates with the second storage volume and, in the second position, the first storage volume is isolated from the second storage volume, further comprising a further one or more storage volumes each provided with a respective one of one or more further valves to connect said further one or more storage volumes to the first storage volume.
