hi frnd my doubt is abt d oil compression.
like air, is d oil can be compressed into an accumulator??
and can its b used for futher power requirements????
pls help me out, frnd..........

No, compressed oil is not a usable form of energy storage, because oil is virtually incompressible. Compressed air works because a tank of it contains many times more air than the same tank at standard pressure. So you can put a regulator on it and get a constant stream of pressurized air. A tank of compressed oil would contain only a tiny amount more oil; it could give you a tiny squirt of high-pressure oil and it would be back to atmospheric pressure.

Small diesel engines like thoose found in a lifeboat can use a hydraulic starter and an accumulatorfor starting the engine. A small hand pump (like a bottle jack) pumps oil into the accumulator where it displaces a floating piston or compresses a bladder. The oil being incompressible causes a trapped volume of air to be compressed. It it the compressed air which stores the energy.
A quick opening valve would be used to send oil rushing from the accumulator to a hydraulic motor which would be used as a starter. The advantage to this system is that there are no batteries to go dead and as long as you can pump the oil back into the accumulator your can restart the engine...
I also worked on a small diesel vessel which used oil accumulators charged by a small electric pump. This enabled the engine to start with the burst of higher torque and speed available from the hydraulic motor while using a small electric pump to recharge the accumulator. (Also had a hand back up) It would take about 10 to 15 minutes to recharge the acculmulator after a starting.

Oil does not compress . Some techniques have used air on top of the oil. U should use hydraulic fluid as it is explosive resistance.

No liquid can be compressed. Only gases can be compressed.
If you used energy to compress air and stored that compressed air in a tank, you could get energy back as you let the air out.

Oil is essentially non-compressible.
